    Holiday Safety

    Stay safe this holiday season with these tips

    As the song goes, “It’s the most wonderful time of the year.” And yes, the year-end holiday season offers many opportunities to celebrate, gather with family and friends and get out of your usual routines. Carrier wishes you all the best for a happy holiday season, and offers the following tips to promote a SAFE season as well.

    If you’re decorating…

    • Be careful on ladders – use every rung and maintain three points of contact (two feet and one hand, for example).
    • When inside, use a step-stool instead of standing on furniture to hang decorations.
    • Don’t overload electrical outlets – inside OR outside. Follow manufacturers’ recommendations for maximum number of lights / decorations per outlet.
    • Monitor fireplaces and candles – don’t leave open flames unattended.

    If you’re traveling…

    • Turn off your water supply at the main shutoff valve. Drain water lines by opening faucets after the water is off to avoid leaks or potential pipe freezing during cold weather.
    • Put deliveries on hold until you return.
    • Put interior lights on timers or install smart bulbs/plugs that can be turned on/off remotely.
    • If driving, use safety belts and car seats.

    If you’re hosting…

    • Wash hands frequently.
    • Be sure to handle meats properly and cook thoroughly to recommended temperatures.
    • Refrigerate leftovers promptly – don’t leave perishable foods out for more than two hours.
    • Keep an eye on children as they play or eat.

    If you’re doing all of the above…

    • Manage stress levels with balanced activity schedules and keep expectations realistic.
    • Maintain sleep schedules to avoid becoming over tired.
    • Avoid over-indulging on sweets, goodies and alcohol – everything in moderation!
    • Don’t overspend – stick to a holiday budget.

    Of course, one sure way to ruin the holidays is an unexpected breakdown with your heating system. To help avoid the unexpected, inspect your air filter and replace if needed, and if you haven’t had your system serviced this year, contact your local HVAC contractor ASAP. Happy Holidays!

    Maximize Spring Break with These Travel Tips

    Spring is around the corner and it’s time to hit the road for a much-needed break from winter routines. While the word “vacation” elicits visions of fun, adventure or relaxation, getting there and making the most of it takes a little preparation.

    Planning your trip

    Pick a destination that has something everyone can look forward to — adults and children alike.

    Once you have a destination in mind, set a realistic budget that you can afford.

    Make flight and hotel reservations early to help save money on travel costs.

    If traveling by car…

    Schedule your vehicle for any needed pre-trip maintenance – oil change, tires/breaks, windshield wipers, etc.

    Keep younger travelers safe with appropriately sized and properly functioning car seats.

    GPS systems and smartphone apps are a great way to get you where you are going, but know your route in advance and bring a printed road atlas as a backup.

    If traveling by plane…

    Try traveling on less popular days and scheduling your flights early in the morning or late at night.

    Be sure to know your airline’s requirements for carry-on and checked bags, including dimensions and weights.

    Bundle your flight reservation with hotel, rental car and amusement park packages to help save you money using online travel sites, or through club memberships.

    Before you go…

    Install smart outlets or timers that can turn lights on and off to give the appearance that your home is occupied.

    Arrange for a trusted relative, friend or neighbor to stop by and check for deliveries, water leaks or other signs of activity.

    Set up some basic home monitoring devices that include indoor and outdoor security cameras.

    Adjust your thermostat for energy savings – better yet, consider upgrading to a smart thermostat like the Carrier® Infinity® System Control.

    And, if you are already calling your local Carrier HVAC contractor about adding a new smart thermostat, don’t forget to schedule your annual spring HVAC system clean and check!

    Staying Productive While Working from Home: 6 Tips for Making Your Home Your Office

    Before COVID-19 changed everything, working from home was more of a nicety than a necessity. But today, many people are being asked to turn their living space into a work space. And while working from home conjures up images of sitting on your couch in PJs with a laptop and a hot latte, creating a productive work environment in your home takes a little effort. Here’s how:

    1. Set some boundaries

    Working from home can disrupt daily routines for you as well as those you are living with. To help keep you focused while limiting distractions, establish regular “office hours.” Then, stick to them as closely as possible – don’t do personal business during office hours and don’t conduct business during your personal or family time.

    2. Carve out some space

    If you don’t have a home office, try to establish a dedicated work area. A guest bedroom, basement or little-used formal dining room are ideal options. If space is tight, get creative – put a small desk in a closet, set up shop in a garage, or put up a folding table in an out-of-the-way corner.

    3. Dress for success

    Sure, it might be a little more comfortable wearing some old sweats and a pair of bunny slippers, but dressing for work can put you in a more business-like state of mind and lead to added productivity. It also sends a message to your housemates that you are “on the clock.”

    4. Keep communication lines open

    Just because you are isolating at home doesn’t mean you can’t reach out to your work associates. Collaborate on work projects using approved phone conferencing systems, email or direct messaging. Keeping in touch with your work friends will make it easier to maintain some sense of normalcy in unusual times.

    5. Give yourself a break

    While you are trying to maintain a consistent work schedule, it’s important keep a consistent break schedule as well. Make sure you take a daily lunch break. And, step away from the computer or phone from time-to-time – stand up, stretch or even step outside for a little fresh air.

    6. Hunker down in comfort

    Because you’ll be spending a lot of time there, you’ll want your home office to be comfortable. Make sure your cooling and heating system is up-to-date on filter replacement and maintenance. Consider a smart thermostat that allows you to control the temperature in your home from your smart phone or laptop.

    It may take a little patience… a lot of communication between you and your housemates… and a little trial and error… but in the end, working from home can be just as productive, if not more, than working at an office.

    Summer Travel Tips for 2020

    Whether it was pre-planned or last-minute, for business or pleasure, traveling in the summer of 2020 looks a lot different than it did just one year ago. Regardless of how you feel about pandemic-era travel, leaving your nest to hit the open road – safely – has always, and will continue to be an exercise in planning, patience and perseverance. Here are some tips to keep in mind when planning this summer’s travels:


    Picking Your Location

    Keep in mind that different states and cities have different restrictions on travel. Be sure to research and understand the current situation in your travel destination, including any self-quarantine requirements. And, be aware that those restrictions can change.


    Method of Travel for Vacations

    According to the CDC, any type of travel can increase your risk of getting and spreading COVID-19. Here are some things to consider as you choose your mode of transportation:

    • Airlines: Most germs and viruses don’t spread easily on flights, but crowded planes and security lines make social distancing difficult and can expose you to frequently touched surfaces.
    • Buses or trains: These methods of transportation make social distancing difficult – you will often be within 6 feet of others.
    • Autos: Stopping for food, gas and bathroom breaks may put you and your companions within close proximity of other travelers and frequently touched surfaces.
    • RVs: Traveling by RV can lead to fewer stops for restrooms and food, but RV parks may offer higher amounts of exposure.


    Health Precautions While Traveling

    Protect yourself and others by following CDC-recommended precautions:

    • Wash your hands often – minimum 20 seconds with soap and water – after touching surfaces, being in a public place, after blowing nose/touching face, etc.
    • Avoid touching your face.
    • Keep social distance of 6 feet or more.
    • In public, wear a face covering (cloth is fine).
    • Cover sneezes and coughs.
    • Pick up food at drive-thru windows, curbside service, or from stores.

    Save Energy and Money at Home While on Vacation

    Any time you will be away from your home, you can save energy by:

    • Turning your water heater down to “vacation mode” – or at least a lower water temperature setting than normal.
    • Unplug “vampire” electronics that use electricity even when they are off – TVs, laptops, printers, etc.
    • Set your thermostat to a higher than normal temperature – or better yet, upgrade to a Wi-Fi®-enabled smart thermostat like the Carrier Infinity System Control for remote monitoring and temperature adjustments.
    • Check your HVAC system’s air filter and replace if necessary. If you are uncomfortable doing this, consider contacting your us for a system inspection or clean-and-check appointment.

    Why do I have one room that’s never the same temperature as the rest of my house?

    No two homes are exactly alike, and every home has its individual quirks. But there is one complaint that is fairly common among homeowners regardless of the size, shape or location:

    “Why is there one room that’s never the same temperature as the rest of my house?”


    Multiple floors/levels

    Whether it’s a 70s era split-level or a brand-new two-story home, keeping the upper levels the same temperature as the lower levels has always been a challenge. That’s due to the physics of rising heat as well as the challenges of delivering conditioned air through longer sections of ductwork.


    Ducting/venting issues

    A long duct run, ductwork traveling through uninsulated areas (like an attic), or not enough return air vents are three typical examples of ducting/venting issues that may not deliver as much heating or cooling as the space requires.


    Oversized or undersized system

    Properly sizing a heating and cooling system isn’t an exact science, and when it’s not done right, you can have serious comfort issues. An oversized system will turn on, then shut down quickly leaving some areas still too hot or cold. An undersized system will just run and run and may never make you comfortable


    Renovations & room additions

    A home remodel can actually change the effectiveness of your heating and cooling system, especially if walls are added or removed. Adding a room means a need for added heating and cooling capacity, which your system may not be adequately sized to handle.


    Location and usage

    A room with southern exposure and lots of windows might generate a lot of extra heat. A finished basement might be cool and clammy. Or a room with computer server and additional heat-generating electronics can add to your home’s comfort needs.


    What’s the solution?

    You may be able to overcome some of these issues with fans, portable heaters, window coverings and the like, but finding a more permanent solution may require a call to the indoor comfort experts – Carrier.

    Whether it’s creating a zoned system with separate temperature control upstairs and down, redesigning your ductwork, or, in the case of sizing issues, potentially replacing existing equipment, Don’s Heating and Cooling can offer a number of solutions for creating a more consistently comfortable indoor environment.

    What Type of Air Filter Should I Use?

    Your heating and cooling system includes an air filter that plays an important role in the life of your equipment, its energy efficiency, and your home’s indoor air quality. That’s why choosing the right air filter for your comfort system matters. Here’s a look at some available filter types, and how to select one that works for your system.


    Typical Filter Types

    1. Standard, 1-inch panel or pleated filter
    The most basic, standard filter is typically about 1” thick and usually features a pleated filter material, flat fiberglass or polypropylene material.  Some 1” filters are made with a flat washable mesh panel. These types of filters should be replaced (or cleaned) every 1-3 months.

    2. Media filter

    Media filters also feature a pleated design and are typically available in 2” – 5” widths. Because they have more filtering capacity, they can typically be changed less frequently, about every months or longer.

    3. Electronic Air Cleaner / Purifier

    Electronic air cleaners apply an electrical charge to airborne particles and then trap them on oppositely charged collector plates or filters. Depending upon the model, these may require monthly cleaning, or, as is the case with the Carrier® Infinity® Air Purifier, require a simple filter change once every 6-9 months.


    MERV Ratings

    You can compare a filter’s “efficiency” by checking its MERV rating. MERV ratings start at 1 and go as high as 20, but MERV 16 is about the highest you’ll find for a residential heating and cooling system. Higher MERV filters can trap smaller particles like mold spores, bacteria and viruses. But before you decide to buy the highest MERV filter you can find, be sure to check with your system’s manufacturer or your HVAC contractor to see if your system can handle a filter with a higher resistance (pressure drop) to air flow that can be associated with a higher MERV filter. Buying the wrong filter can make the system work harder and potentially shorten the life of the system.


    Selecting the right air filter

    Selecting the right filter for your home can be as easy as using the same type, same size and same MERV rating filter that you currently have. If you want to explore an inexpensive upgrade, consider purchasing the same type and size of filter with a higher MERV rating, as long as your system allows for it. Or, if you want to upgrade to a different type of filter altogether, such as moving from a media filter to an electronic air cleaner, contact us for a quote on filtering options that will best complement your current indoor comfort system.

    Ten Tips for Winter Grilling

    Ten Tips for Winter Grilling from the Hearth, Patio & Barbecue Association.  Don’s Heating and Cooling has been a member of HPBA and HPBAC for several years

    There’s “Snow” Reason Not to #Wintercue

    ARLINGTON, VA (Nov. 17, 2020) – Temps are falling, days are getting shorter and there’s every indication that this season we will be staying in and cooking at home more than any winter before.

    Here’s one way to get by: don’t put that grill or smoker away. Instead, embrace backyard cooking through the fall and all winter long.

    “Most people think of barbecuing as a spring and summer past-time, but in reality, there’s ‘snow’ reason not to grill out all year long,” said Emily McGee, Senior Communications Director for Hearth, Patio & Barbecue Association (HPBA). “We call it #Wintercue. Think stews, soups, winter veggies and holiday meals over the flame – any winter meal you’d otherwise make in your indoor kitchen can be made better cooking in our backyard. Grilling and smoking can be a great way to get through the winter, especially this year when we’ll likely be staying home much more.” 

    HPBA offers these 10 tips for grilling out in the months ahead:

    1. Don’t peek! Heat escapes quickly and you’ll be adding on cooking time. Limit lifting the lid except for turning and flipping foods.
    2. Plan on adding 25% more cooking time to compensate for cold temperatures. Use a reliable food thermometer to check.
    3. Consider adding a propane heater to your patio this year. Of course, these heaters can make barbecuing and entertaining in winter much more comfortable.
    4. Make shorter trips outside by moving your barbecue grill a little closer to the house, but make sure you still keep it at least 10 feet from any buildings or structures. Never grill in enclosed spaces, such as a garage or under an overhang, that can trap deadly carbon monoxide.
    5. Position gas grills so the wind is perpendicular to the gas flow, and not blowing the flame down the burner tubes. A sturdy patio umbrella set on its side can also serve as a wind block. When lighting the grill, do not turn the handwheel on the propane tank all the way on. Instead, use a single turn before lighting.
    6. Check that everything is in working order before using your grill. Don’t force a frozen knob or grill lid – you’ll risk cracking it or breaking the seal. Instead, move your grill to a garage where it can thaw or use a hair dryer.
    7. You’ll want to dress warmly, but avoid hazardous bulky clothing and tuck in loose scarves. A pair of easily-removable boots or shoes is a good idea when making trips in and out of the house. You’ll find heat-resistant gloves with plenty of dexterity are worth the investment.
    8. The days are shorter in the winter, and you’ll likely be grilling in the dark. While your favorite flashlight works, it can be hard to juggle with your grill tools. Clip-on or magnetic grill lamps are a handy upgrade for monitoring your cooking.
    9. Consider a wireless remote or instant read thermometer your new best friend. A leave-in remote thermometer allows you to monitor cooking temperature while you stay warm inside, and an instant read thermometer will minimize your time in the cold.
    10. When not in use (and only when completely cooled), protect your grill from the elements with a snug cover.

    About the Hearth, Patio & Barbecue Association (HPBA)

    The Hearth, Patio & Barbecue Association (HPBA), based in Arlington, Va., is the North American industry association for manufacturers, retailers, distributors, representatives, service firms and allied associates for all types of barbecue, patio and hearth appliances, fuels and accessories. The association provides professional member services and industry support in education, statistics, government relations, marketing, advertising and consumer education.

    What Temperature Should I Set My Thermostat?

    Trying to decide what temperature to set your thermostat? You are not alone! Your thermostat settings not only affect your comfort, they can have a big impact on your utility bills as well. And while the ideal thermostat setting for your home is largely based upon personal preference, there are ways to achieve a comfortable balance between comfort and energy savings. 


    Here are some tips on how to find the right temperature setting for your home:



    Regardless of whether you are more interested in comfort or savings, finding that sweet spot on the thermostat may take a little trial and error. A good rule of thumb for energy-saving heating is to set your thermostat at 68° F. For more comfort, try increasing the temperature by 1 or 2 degrees at a time. For energy savings, turn the temperature down 1 or 2 degrees at a time.



    During the hotter, more humid months, nothing beats the relief of a cool, humidity-controlled home. To find your happy place, try setting your air conditioning system at 78° F for a good mix of comfort and energy efficiency. Then, adjust as needed to find your comfort zone.



    According to the Department of Energy, you can save up to 10% a year on your heating and cooling when you set back the thermostat 7-10 degrees from your normal setting, for 8 hours a day. Do this at night when you go to bed, and during the day when you go to work.

    • During the heating season: Try turning the heat down and bundling up – wear a sweater or light jacket, fuzzy slippers, etc. Open window coverings to allow natural sunlight in and let Mother Nature help warm your home.
    • During the cooling season: Try turning up the AC temperature and supplementing with a fan – either a free-standing type or a ceiling fan. Close window coverings to minimize the sun’s warming effect.
    • All year long: Get a programmable thermostat that can automatically adjust the temperature for comfort when you are home or awake. Some of these models will also “learn” your patterns and automatically adjust to help maintain both comfort and energy savings. And, Wi-Fi® thermostats give you even more flexibility with comfort control from your smartphone, tablet or computer. Our Wi-Fi thermostats must be connected to Wi-Fi for remote connectivity. You need an iOS® or Android® mobile device to use our app.

    If you just can’t get comfortable at all after experimenting with the temperature in your home, it might be time to get an expert opinion from Don’s Heating and Cooling. We can analyze your HVAC system to make sure it is operating properly, and make repairs if necessary. That’s a solution most people can get comfortable with!

    The Best Part of Owning a Ductless Heating System

    Just how owning a cooling system is necessary for summer, the same can be said for a heating system. With various situations worldwide, many individuals have turned towards working from home and attending classes from home. Considering that certain rooms within the household have not been fitted with ductwork, it becomes impossible to have a new system installed unless fitted with one or only used at certain times of the year.

    To make matters easier, Don’s Heating and Cooling in Orangeville and Alliston provides and helps with the installation of ductless heating. Apart from being easy to install, these systems help maximize the use of every room and space within your home.


    Benefits That Ductless Cooling Can Provide

    Considering that ductless cooling systems act as an additional part to the systems you already have, it does not need ductwork to be pre-fitted by Don’s Heating and Cooling. For those unaware, here are a few other benefits of owning a ductless cooling system.


    A More Efficient System
    One of the main aspects of ductless cooling systems is that they use a modernized heat pump technology that is regarded as a highly energy-efficient way to help cool your home. Being more efficient than the standard Air Conditioners, they also help save on your utility bills as they use a lesser amount of power to function.


    It Can Act as both – a heating and a cooling system
    People who own a space heater have to invest separately in a cooling system for summer. This also means that these systems are being used once a year and forgotten for the remainder of the time. Ductless systems can act as both a cooling and a heating system, allowing you to use them all year round. Contact Don’s Heating and Cooling to get yours installed.


    Minimal Amount of Construction required
    Like any regular HVAC unit, a ductless system also comes with two components. One is the outdoor unit, and the other is the indoor unit. However, unlike the others, these two units are only connected with a diameter tubing that is small in size. This guarantees almost no construction mess as the system is easy to put together quickly, without any hassle.


    Allows Your Original cooling system to operate more efficiently
    Considering that a ductless cooling system is an additional unit to the system you already own, your original cooling unit functions more efficiently. The ductless system prevents your original unit from having to exert more energy and helps in balancing out the temperature in each room and corner of your home.


    Provides Precise Control for your comfort level
    One of the advantages of a ductless cooling system is that it comes with remote control. This makes the system’s operation easier as you can adjust the temperature to that which you desire easily. To have one installed, schedule an appointment with Don’s Heating and Cooling.

    3 Reasons Why Your Home’s Air Equipment Needs Love Too

    Your home is the place where you spend the most amount of time. As the central gathering place for you and your family, you want to make sure that everyone is breathing the best air possible. When your home’s air equipment needs some care and attention, it can be useful to have the experts come take a look.


    You and Your House Breathe Easier

    Everything from the vents to the filters to an air purifying system lead to better breathing quality for everyone involved. Most people know that humans are much like plants in that we need a good air source to live better lives. When our homes are having a difficult time breathing as well, it can put a strain on you and your family. Having a professional come out to service your home’s air equipment can save your mind the worry and your home from working double time.


    Air Quality

    Likening a human to a plant is accurate in how we function and are able to breathe. When the air equipment in your home isn’t working the way it should, it can affect the overall air quality. When you suspect that your filters, air exchanger or purifier aren’t working the way they should, calling to get them serviced can save your family breathing concerns for the future.


    Not Just the Filters

    There are many parts to your home’s air system. From air filters to air exchangers and even air purifiers there are a lot of moving parts to ensure you and your family are breathing well throughout the year. It’s always important to double check with the professionals if you think your home’s air equipment isn’t working the way that it should be. Never simply think that changing the filters will fix the problem as there could be something more serious at play in your home’s breathing.



    From making sure that you change your air filters frequently to calling in the professionals occasionally for any of the large air equipment, you can always guarantee that you and your family are breathing easy in the future. Make sure to always check with a professional when your home’s air equipment isn’t functioning the way it was designed to. Now it’s time to get back to being the healthy human plants you are.

    What should the humidity be in a house?

    Anybody familiar with the cliché, “It’s not the heat, it’s the humidity,” recognizes one of the basic benefits of controlling humidity in your home: it can help you feel more comfortable. However, keeping humidity in check can also help control the quality of the air in your home. While everybody is a little different in terms of what feels comfortable, the EPA recommends maintaining humidity between 30% and 50% to help improve indoor air quality.1


    How humidity affects your comfort

    Humidity’s role in your comfort is supported by science. Your body cools itself by sweating, and how much you sweat is affected by the amount of moisture in the air. With more humidity in the air, your sweat evaporates more slowly, making you feel hotter and less comfortable.  In addition to making you feel less comfortable, high humidity can affect your home’s finishes and furnishings, including causing stains or peeling paint and wallpaper.

    On the other side of the equation, low humidity, often associated with cooler climates or heated indoor air, can cause discomfort with dry skin, throats or nasal passages.


    How humidity affects indoor air quality

    Concentrations of indoor air pollutants can be affected by the humidity level in your home. As an example, high indoor humidity can be linked to an increased opportunity for mold growth. Keeping indoor humidity between the previously described 30 – 50% is recommended because, as stated by the EPA, “moisture control is the key to mold control.”


    How to control humidity

    You can help control the humidity in specific rooms or areas of your home using a portable dehumidifier, running the bathroom fan when showering, using the range hood fan when cooking, or using a vaporizer.

    For a more controlled, whole-home approach to humidity control:

    Run your central air conditioner during the summer, because it actually dehumidifies as it cools your home. Carrier® systems with Ideal Humidity System® technology ensures that they operate to extract the most humidity from your home as possible.
    Install a whole-home humidifier to provide relief from overly dry winter air.
    Consider adding whole-home ventilation, such as a Carrier® heat recovery ventilator (HRV) or energy recovery ventilator (ERV).

    How often should I change my air filters?

    When properly maintained, your indoor heating and cooling system should provide many years of reliable comfort. One of the easiest ways you can help keep it operating at its best is through routine filter inspections and replacement. According to the U.S. Department of Energy, “Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.”

    Proper filter maintenance starts with regular, monthly inspections. How often you should actually replace the filter will depend upon what type it is. Each filter manufacturer should have a recommended replacement schedule. If not, use the following as a guide:

    1-inch filter

    1-inch filters are typically the most basic type available and should generally be replaced every 30 days.

    Pleated filter

    Pleated filters come in a variety of thicknesses and provide a greater surface area for filtration. These filters typically can provide up to 6 months of protection. Inspect the filter every month, and replace the filter if you see excessive dust/dirt buildup.

    Electronic air cleaner / whole-home air purifier

    Electronic air cleaners and whole home air purifiers like the Infinity® air purifier from Carrier use electronic filtering processes to remove airborne particles from the air. The Carrier® Infinity air purifier captures AND kills many airborne pathogens.*

    These more advanced filtering devices typically include a removable filter that should be inspected and replaced per the manufacturer’s recommendations.

    According to the EPA, indoor levels of pollutants are often significantly higher than outdoor levels. And, most homes have at least one air quality problem, ranging from temperature and humidity issues to particle allergens, chemical pollutants and elevated carbon dioxide levels.

    Brought on by everyday activities like cooking and cleaning, indoor air pollutants can put you and your family at risk, while generally making for a less comfortable, less efficient home. For instance, carbon dioxide levels in today’s “tight”, energy-efficient residences can quietly climb above 1,000 parts per million. Volatile organic compounds (VOCs) found in many common household products such as cleaners, dry-cleaned clothing, ink-jet printers, pesticides and air fresheners, can irritate the eyes, nose and throat, cause difficulty breathing and nausea, and damage the central nervous system as well as other organs according to

    Fortunately, there are a number of products on the market that are designed to enhance and improve indoor air quality through filtration, ventilation and humidity control. Many of these products can be installed by Don’s Heating and Cooling. When you consider that Canadians on average spend approximately 90 percent of their time indoors according to the EPA, it’s easy to see why indoor air quality products can be an attractive addition to people’s homes.

    Here’s a look at some common indoor air quality issues and products that can provide a solution:



    • Pollen and mold spores enter through doors and windows
    • Bacteria and viruses can linger in your air
    • Fine dust particles get kicked up from floors and furniture
    • Dander and hair fall from pets




    • Dry nasal passages
    • Discomfort of dry, itchy skin
    • Annoying static shocks



    • Airborne irritants such as dust mites and mold
    • Warping or structural damage to wood flooring or home furnishings



    • Stale air
    • Higher than average utility costs
    • Pollutants from carpet off-gassing, paint, household chemicals



    • Mold spores inside the cooling coil
    • Bacteria and fungi inside the cooling coil
    • Contaminants can become airborne and circulate through your HVAC system



    • Dust, dirt, pollen and more circulated through heating and cooling vents
    • Polluted indoor air
    • Damage to home furnishings
    • Reduced performance of home comfort systems



    Testing Home Air Quality

    Although indoor air quality isn’t always something you can see, there are contractors equipped to help you out. Using an indoor air analyzer, a qualified Air Quality Analyzer can provide test results in about 30 minutes, then get right to work addressing your home’s air quality issues by recommending an indoor air quality product designed to solve the problem.

    Prepare for Winter with These Five Ways to Winterize Your Home

    Old Man Winter is on his way, and he’s packing his usual bag of tricks – snow, sleet, freezing temperatures and more. But before you start waxing your skis and dragging out the old toboggan, it’s time to start winterizing your home to protect it – and your family – from the elements.


    Check seals around windows and doors

    Any entryway into your home can let heated air out and colder air in if not properly sealed.

    Windows: Use plastic cling wrap or buy a window sealing kit from a local retailer. Also, insulated drapes or window coverings can help reduce drafts and energy loss.

    Doors: Check, and if necessary, replace the weather stripping around the frame of all exterior doors.


    Caulk, paint, repair

    Caulk: Check your home exterior for gaps in door and window frames, wood trim, fireplaces and locations where wiring and piping enter your home. Use a high-quality caulk to seal any gaps.

    Paint: Look for exposed wood surfaces. Scrape any loose paint, clean the area, and apply a good quality paint to protect the wood.

    Repair: Visually inspect your home for loose shingles, poorly installed siding, rotting wood or cracks in masonry. Hire a contractor if you cannot make the repairs yourself.


    Clean the dryer vent

    While this one is easy to forget, your dryer vent will build up a layer of lint during normal operation, causing longer drying time and worse – it can be a fire hazard. Cleaning your dryer vent about every six months, including once in the fall, should be on everyone’s to-do list. If you can’t do it yourself, hire a reputable vent-cleaning contractor.


    Smoke & Carbon Monoxide (CO) detectors

    It’s always a good idea to check your smoke alarms and CO detectors on a regular basis. And because you will likely be spending more time inside and potentially using CO generating appliances such as a gas furnace during the winter, fall is a great time to test and if necessary, replace your smoke alarms and CO detectors.


    Furnace maintenance

    Inspect your furnace filter monthly and replace as needed according to the manufacturer’s recommendations. Hire a qualified Carrier HVAC contractor to perform an annual maintenance and cleaning appointment for your heating system.

    Taking the time to tackle these tasks can help save energy, improve your family’s comfort and help prevent bigger home repairs down the road.

    Air Conditioning and Covid-19: Slowing the Spread

    A generation of research and experience has proven that when properly maintained
    and operated, heating, ventilation and air-conditioning systems (HVAC) can reduce
    the spread of viruses. These critical building systems not only provide thermal
    comfort but, according to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), may also improve resistance to infection.

    The American Society for Microbiology (ASM) has recently addressed the issue of COVID-19 transmission in the “built environment” (BE), defined as the buildings, automobiles and other indoor settings in which most humans spend more than 90 percent of their daily lives.

    There are several major transmission vectors that promote infection in these built
    environments, the report says, including occupant density, the amount of social activity and interaction, and human
    contact with abiotic surfaces. The cruise ship industry, nursing homes and prisons have taught us about the risk of
    transmission from settings where these vectors intersect. However, we also have learned that proper hand-washing
    and social distancing work to reduce transmission.

    Alongside these primary mitigants, HVAC systems work in a built environment to supply comfortable, clean,
    recaptured air, mix in healthy levels of fresh air, and contain or exhaust contaminants. Air delivery systems can reduce the transmission of viruses through inline filtration, something HVAC professionals are capable of assessing.
    Air-conditioning systems are also critical in maintaining healthy humidity levels. “Maintaining a RH (relative
    humidity) between 40% and 60% indoors may help to limit the spread and survival of SARS-CoV-2 within the BE,”
    the ASM suggests, “while minimizing the risk of mold growth and maintaining hydrated and intact mucosal barriers
    of human occupants.”

    The Centers for Disease Control (CDC) echoes these findings, saying that employers can decrease the spread of
    COVID-19 by maintaining a healthy work environment. “Consider improving and engineering controls using the building ventilation system,” the CDC suggests, including increased ventilation rates and increased percentage of outdoor air circulating through the system.

    Well before COVID-19, the Healthy Building Movement had begun to measure and improve air quality in the built
    environment to improve productivity and health. Of the nine foundations for a healthy building, five relate to HVAC,
    including air quality, ventilation, thermal health, moisture, dust and pests. “There’s just no reason anymore to
    economize on airflow and filtration,” Harvard Business School’s John Macomber says. “It’s a cheap way to help people be healthier.”

    A Restaurant Story
    Modern, professionally maintained air conditioning can play a positive role in the
    control of COVID-19 by ensuring a healthy built environment during and after
    the pandemic. But news reports about an incident in a restaurant in China have
    attributed the spread of the virus to the restaurant’s air-conditioning system.
    Technically, none of this reporting was incorrect, but a careful look at the
    underlying details reveals a very different story.
    By February 10, 2020, 10 people from three families who had eaten at the same air-conditioned restaurant in
    Guangzhou were infected with COVID-19. Researchers at the Guangzhou Center for Disease Control and Prevention
    believe that the virus was transmitted from an asymptomatic 63-year-old woman in one family to at least one
    member of each of two nearby families seated at neighboring tables about 1 meter apart. Because immunologists
    are confident that COVID-19 can be transmitted via large infected droplets caused by talking, sneezing or coughing,
    the researchers believe that this diner’s infected droplets — normally heavy enough to fall to the floor before
    reaching a table 1 meter away — were boosted by airflow from the restaurant’s air conditioning.

    Seventy-three other restaurant customers were identified as having close contact with members of those three
    families, but none developed COVID-19 symptoms. Neither did the eight restaurant workers serving those guests.
    Six smear samples from the air conditioner’s air outlet and air inlet also tested negative for the virus.
    In other words, the restaurant’s air-conditioning system was virus-free and operating as intended. “The key
    factor was the direction of the airflow,” researchers surmised.

    Proper airflow management is essential. Without knowing all the details in this case, it is likely that improper air
    distribution, combined with a lack of social distancing, may have contributed to the transmission in this restaurant.
    It is important to manage airflow and airflow velocity in an occupied space. Research and ASHRAE guidelines
    point to an upper limit of air velocity in an occupied space of 40 fpm. To achieve this condition, the air needs to be
    properly blown by the HVAC system into the room, and properly distributed in the occupied space. It is unclear if the
    restaurant in this case met these criteria, but, based on the researchers’ conclusions, it appears unlikely.
    “To prevent spread of COVID-19 in restaurants,” the report concludes, “we recommend strengthening temperature monitoring surveillance, increasing the distance between tables, and improving ventilation.”
    Nowhere in the report is there any suggestion of turning off the air conditioning as a mitigating action.

    HVAC Best Practices
    As previously mentioned, HVAC systems and the built environment can play an
    important role in preventing the spread of viruses. To ensure the proper indoor air
    purity, a good HVAC system should include some or all of the following:
    1. (Demand Controlled) Ventilation: When outside air is not provided via separate devices, the HVAC system should
    provide outside air based on the size/use of the space. Where possible, the HVAC system should include a sensor for
    carbon dioxide or other pollutants to calculate and correct in real time the amount of ventilation needed. It is important to be aware that the increase of the ventilation rate may cause an increase of load, and the HVAC unit, if not properly sized, may not be able to provide sufficient cooling capacity. In such situations, it may be appropriate to consider Direct Outdoor Air Supply (DOAS) units, which are specifically designed for large amounts of outside air.

    2. Filtration: Filters are rated on their ability to capture and retain particles of different sizes. The industry standard
    is a Minimum Efficiency Reporting Value (MERV) rating. Filters with MERV>13 have a significant ability to capture
    particulate matter (PM) and smaller particles. HEPA filters are even more efficient and are able to capture bacteria and viruses. Note that there are important tradeoffs to consider: the higher the filtration requirements, the greater the air pressure drop and the size of the filter. For this reason, the air management system of the HVAC needs to be carefully sized based on the filtration requirements.

    3. Other Indoor Air Quality Devices: Numerous technologies are available to reduce the presence of contaminants.
    Ultraviolet lights, ultraviolet photocatalytic oxidation, ionization, plasma, electrostatic active, active carbon and other components can be installed to specifically target volatile organic compounds (VOC), bacteria and viruses. Some of these options can be available as integral parts of the HVAC system.

    Air Distribution:
    1. The airflow rate, air velocity and direction of the air discharged by the air-conditioning unit need to be carefully
    controlled. The goal is to have uniform distribution of temperature in the room and to avoid air velocities above 40
    fpm in the occupied space, thus avoiding draft and risk of carrying particles from one part of the room to the other.

    2. The total amount of airflow needs to be properly calibrated to the cooling capacity of the unit (a best practice
    in North America of 200-400 cfm/ton is often quoted). In addition, the cooling capacity of the unit should not be
    oversized or undersized compared with the cooling load of the space.

    3. The location of the air outlet, the orientation of the air and the intensity of the air velocity at the discharge tend to
    determine the airflow in the room and need to be optimized. The more the air is blown directly to an occupied area,
    the more we will have a “spot cooling” effect and the worse the air distribution will be. On the other hand, an ideal
    distribution is achieved by: (1) locating the air outlet in a position that ensures good airflow, but does not directly
    blow air into the occupied space; (2) ensuring that air has the possibility to travel and expand before reaching the
    occupied space.

    Air Conditioning Facts
    Air conditioning is defined as the process of controlling temperature, humidity,
    purity and motion of air in an enclosed space. The main goal is to provide
    comfort to the occupants or needed precision temperature and humidity
    In addition to comfort, good air conditioning improves health by reducing discomfort and thermal stress
    and associated susceptibility to viruses.8
    It is also proven that proper air conditioning in buildings increases productivity in schools and offices.9
    In general, the primary parameters of indoor comfort/health are:
    Temperature: It is the primary element of comfort. The ideal temperature (typically set using a thermostat)
    varies depending on numerous conditions (season, location, clothes, etc.). ASHRAE and CDC recommend10 a
    range of 68.5-75 F in the winter, 75-80.5 F in the summer.
    Humidity: Excessively high or low humidity leads to discomfort. A target range of 40%-60% relative humidity is
    normally used for comfort. ASHRAE recommends relative humidity below 60%.
    Air Purity: In general, the presence of particulate, gases (carbon dioxide (CO2), radon, volatile organic
    compounds), as well as viruses and bacteria cause poor air quality, with negative consequences for the
    occupants. Air conditioning helps improve air quality with various techniques, of which the most widely used are
    outdoor ventilation and filtration. ASHRAE prescribes specific ventilation rates depending on the application.11 For
    instance, a conference room should see an outdoor ventilation rate of 15 cfm/person.

    Air Velocity/Air Distribution: It is important that no sensation of draft (unwanted local cooling of the body
    caused by air movement) is caused by the air conditioning or other elements of air movement in the occupied
    space. Research and ASHRAE guidelines point to an upper limit of air velocity in the occupied space of 40 fpm.12
    To achieve this condition, the air needs to be properly blown by the HVAC system into the room, and properly
    distributed in the occupied space.

    Three Things You Should Avoid Doing to Your Air Conditioner

    Generally, you might come across things that homeowners should do for their air conditioners, such as replacing air filters or clearing and cleaning air vents. Although, there are several things you must avoid doing as it can cause your air conditioning system to malfunction. 

    There is a lot at stake, from system warranties to delicate components. Don’t hinder the health of your air conditioner by attempting a do-it-yourself repair. Make sure you hire a professional. A good rule of thumb to learn when it comes to air conditioners is letting the professionals look after the issues related to the air conditioner. 

    If you don’t believe you should be opening a particular AC component to perform a task, it’s best to avoid it. Anything other than replacing an air filter is going to be interference into a technical area. Here are 3-things that you should avoid doing to your air conditioner:


    Keep Adjusting The Thermostat:

     If you have to keep regulating the thermostat to maintain a comfortable temperature, you are raising the workload on the A/C and increasing the chances of costly repairs or untimely equipment failure. To increase comfort and save energy, add more insulation and seal air leaks in your home.


    Forgetting to Change the Air Filter: 

    A clogged air filter can reduce essential airflow over the evaporator, resulting in coil icing and decreased cooling output. These operating conditions also put additional strain on the A/C compressor, causing it to fail abruptly. 

    Examine the filter monthly and clean or replace it when it becomes dirty to avoid these issues and reduce your cooling energy consumption by up to 15%.


    Neglecting Annual Maintenance: 

    Allow an HVAC professional to perform AC maintenance before each cooling season to keep the air conditioner running optimally and efficiently. Without a yearly tune-up, an A/C can lose up to 5% of its cooling capacity each season. 

    Routine servicing also allows professionals to detect and correct minor issues before escalating into inconvenient breakdowns and costly repairs.

    5 Furnace Tips for New Homeowners

    Five Furnace Tips for New Homeowners

    1. Know the Details

    Not all HVAC systems are the same as there are many types of equipment that heat and cool homes. For example, an HVAC system may have an air conditioner and gas furnace, or a heat pump and an electric furnace. If a home uses a boiler for heat, it might run on propane, oil, natural gas or a different type of fuel. If your realtor didn’t provide you with information regarding the type of heating and cooling systems in your home, now is the perfect time to learn more about it. In addition to knowing about the types of equipment used, it is also a good idea to know about their energy sources and any add-on systems, such as zoning systems, air purifiers and dehumidifiers.


    2. Replace the Filters

    Don’t assume that the previous homeowners replaced the filters in the heating and cooling units before they handed you the keys. Even if your home is brand new, contractors might have used the HVAC system to create an environment that’s ideal for drying paint, drywall, adhesives and other materials. When you move in, replace the HVAC filter to ensure the system works efficiently and circulates clean air throughout your home.


    3. Schedule a Professional Maintenance and Inspection

    Waiting until the HVAC system has a problem to call a professional could backfire on you because you might find yourself without heat on the coldest winter day. If your home is not brand new, hire an HVAC professional to inspect and maintain the system as soon as possible. The specialist will alert you to small problems that could become expensive repairs if they aren’t addressed, tell you more information about the system (e.g., the type and age), and give you maintenance tips that you can do on your own throughout the year to keep the unit running more efficiently. Schedule professional HVAC maintenance and inspection every year to prolong the life of your heating and cooling units and prevent the need for major repairs.


    4. Know Details about the Warranty

    Learn about the warranty that came with the heating and cooling systems in your new home. Details to pay attention to include the period of coverage and the types of repairs the warranty covers. Keep in mind that if the previous homeowners failed to hire a licensed professional to complete annual maintenance on newer HVAC equipment or failed to hire a professional to perform certain repairs, they may have accidentally voided the warranty.


    5. Learn to Use the Thermostat to Maximize Efficiency

    A programmable thermostat helps ensure your system operates efficiently throughout the year. Take advantage of its various settings to keep your home comfortable when it’s occupied and to save energy while you’re asleep or on vacation. An HVAC specialist can show you how to program and operate the thermostat, as well as make recommendations regarding the best temperatures settings.

    Furnace efficiency rating: What is AFUE and why is it important?

    Winter is around the corner, and that means it’s time to check in on the old heating system. And if it’s time to think about replacing an aging furnace or boiler, you should know about AFUE.


    What is AFUE?

    AFUE is an acronym for Annual Fuel Utilization Efficiency. It’s a standardized measure of the fuel efficiency for furnaces and boilers, used much the same way you would use miles-per-gallon (MPG) for cars. According to

    • AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler.

    • It is expressed in terms of percentage. For example, if you have a 90% AFUE furnace, 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere.

    • AFUE does not account for heat loss resulting from ducting or piping in an unconditioned space, such as an attic or garage.


    Why is AFUE Important?

    The Federal Trade Commission requires new furnaces and boilers to display their AFUE so consumers can compare the efficiency of different models. As you research your new heating system, keep in mind that the Department of Energy puts efficiency levels into three categories:

    Low efficiency – older models with AFUE in the 56 – 70% range (new units must meet current AFUE minimums, which are higher)

    Mid efficiency – 80% – 83% AFUE (these models meet current minimum standards for new equipment)

    High efficiency – 90% – 98.5% AFUE (many of these models also offer comfort-enhancing technology in addition to high energy efficiency)

    When making a purchase decision using AFUE ratings, it is important to note that models with higher AFUEs are often deluxe units with extra features such as:

    • Two heat exchangers

    • Multi-stage heating

    • Variable-speed fans

    • Communicating “intelligent” controls

    The added components and technology can lead to higher price tags for the higher AFUE models.


    Making the right decision for your home’s furnace efficiency

    Actual performance and efficiency of any furnace or boiler in your home will depend on additional variables including:

    • Age, size and condition of home

    • Condition and quality of windows, insulation and ductwork

    • Personal temperature settings and usage habits

    Your local Carrier HVAC contractor can be an excellent source for navigating the many AFUE options available for your new heating system. They have the tools and expertise to assess your home, your personal preferences and your budget considerations to help you make the right decision for your family.

    Why is my furnace blowing cold air?


    Winter can be a real gut-check with its cold, blustery wind, rush-hour snow storms and some downright frigid nights. It can also be a great time to hunker down on the couch, grab a blanket and enjoy the warm, soothing comfort coming from your heat registers.

    But what happens if you settle in only to find – gasp – cool air blowing from the register? Don’t panic yet. Cool air from your heat vents doesn’t always mean you have to make a late-night call to your local Carrier HVAC contractor. There are a number of perfectly normal explanations that you can remedy yourself.


    Check the thermostat


    First, take a look at the brain of your comfort system – the thermostat – and check for the following:

    • Make sure it is set for heating, and not for cooling.
    • Check the fan setting. The “on” setting circulates air continuously whether it’s been heated or not. Change it to “auto” so it only blows warm air into your home.
    • Compare the temperature setting to the actual temperature in the home. You may need to turn up the set temperature for more heating comfort.
    • If you have a programmable thermostat, review temperature settings and make sure they still line up with when you are home or away from home.

    Check the furnace filter


    Check your filter and if it’s dirty, replace it. In some cases, a clogged, dirty filter might restrict airflow enough to affect your comfort. Or in more extreme cases, an overly dirty filter can cause the furnace to overheat and shut down.


    Signs that it’s time to call an HVAC contractor


    Unfortunately, sometimes cool air from the register DOES mean an issue is lurking that your Carrier dealer will need to address. Knowing what to look for can help your HVAC contractor get to the issue – and the resolution – a little quicker.

    • Fan limit switch: A malfunctioning fan limit switch might cause the furnace blower to circulate cool air when the furnace isn’t heating, or shut it down completely
    • Flame sensor: If the temperature inside is cooler than the thermostat’s setting, or if the furnace turns on and off repeatedly, a flame sensor may be malfunctioning.
    • Leaking ducts: If air from the registers is cooler and/or weaker than usual, and you notice higher heating bills, your air ducts may be leaking.
    • Pilot light is out: If you have a pre-1990s furnace, a furnace blowing cool air or shutting down may indicate that the pilot light is out. Follow the manufacturer’s instructions to re-light.

    If you do end up contacting your Carrier dealer, doing a little advanced troubleshooting might help make the process faster, more efficient, and maybe save a little time on the service call.
