How to Improve Indoor Air Quality as You Transition from Summer to Fall

As homes become more enclosed during the cooler months of fall, maintaining good indoor air quality becomes essential. Closed windows and reduced airflow can lead to a buildup of allergens, dust, and pollutants that negatively impact your health and comfort. Thankfully, there are several advanced solutions that can help you maintain cleaner air during this transition period.


1. HRV and ERV Systems for Better Air Circulation


As you begin closing windows and sealing your home from the cooler fall weather, Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs) offer a perfect solution to maintain fresh air circulation without compromising your home's energy efficiency. These systems exchange stale indoor air with fresh outdoor air, while also recovering heat to maintain a consistent temperature inside.


  • HRV Systems are ideal for colder climates and focus on recovering heat while ensuring proper ventilation.

  • ERV Systems not only recover heat but also manage humidity levels, making them an excellent option for homes with varying humidity conditions.


Both of these systems are highly effective in improving indoor air quality by reducing the buildup of pollutants, moisture, and odors. For homeowners in Orangeville, Alliston, and surrounding areas, Don’s Heating and Cooling offers expert HRV and ERV installation services to help you enjoy fresh, healthy air without losing energy efficiency.


Tip: Consider installing an HRV or ERV to keep fresh air flowing through your home, especially during the fall and winter months when your home is more sealed.


2. UV Light Systems to Eliminate Harmful Pollutants

Another advanced technology for improving indoor air quality is UV (ultraviolet) light purification systems. These systems are installed within your HVAC system and work by using ultraviolet light to eliminate airborne pollutants such as bacteria, viruses, and mold spores.


UV lights are particularly beneficial during the fall when homes tend to have more stagnant air. By installing a UV air purifier, you can reduce the spread of harmful pathogens and improve the overall air quality in your home. These systems are designed to keep the air in your home as clean as possible, benefiting those who suffer from allergies or asthma.


Tip: Consider adding a UV light system to your HVAC unit for cleaner, healthier air throughout the year.


3. Schedule Regular Duct Cleaning

One of the most effective ways to maintain clean air in your home is by having your ductwork professionally cleaned. Over time, dust, pet dander, and other contaminants accumulate in your HVAC system’s ducts. When the heating system kicks in during the fall, these pollutants can be circulated throughout your home.


A professional duct cleaning will help ensure that these particles are removed, improving air quality and even enhancing the efficiency of your HVAC system. Cleaner ducts can also lead to energy savings as your system doesn’t have to work as hard to circulate air.


Tip: Consider scheduling professional duct cleaning every couple of years, especially if your home has pets, smokers, or someone with allergies.


4. Replace Your HVAC Filters Regularly

As your HVAC system transitions from cooling to heating, fall is the perfect time to check and replace your air filters. Air filters trap dust, pollen, and other particles, preventing them from being recirculated into your home. Over time, filters can become clogged, reducing the system’s efficiency and causing poor indoor air quality.


Tip: Check your HVAC filters every month and replace them at least every three months. For households with pets or allergies, more frequent changes may be necessary. Contact Don’s for filter replacements or to schedule a maintenance check.


5. Invest in an Air Purifier

Air purifiers are an excellent investment for improving indoor air quality, especially during the fall and winter when homes are more sealed. Air purifiers help remove airborne pollutants such as dust, pet dander, mold spores, and even bacteria.


Don’s Heating and Cooling offers UV air purification systems that use UV light to eliminate harmful particles, keeping your home’s air clean and safe. These systems can also reduce allergens and improve the overall comfort of your home.


Tip: Place air purifiers in frequently used areas like the living room and bedrooms to maximize their effectiveness.


6. Maintain Proper Humidity Levels with a Humidifier

As the weather cools, indoor air can become dry, leading to uncomfortable symptoms like dry skin, irritated nasal passages, and even worsened respiratory issues. A whole-home humidifier can help maintain optimal humidity levels, making your indoor environment more comfortable.


Humidifiers also protect your home’s wood furniture and flooring from damage caused by dry air. Don’s Heating and Cooling offers a variety of Carrier humidifiers, from steam to fan-powered models, to suit your home’s specific needs.


Tip: Keep your home’s humidity levels between 30-50% for maximum comfort and air quality.


7. Ensure Proper Ventilation

As fall sets in, it’s tempting to seal up your home completely, but proper ventilation is essential for maintaining good indoor air quality. Without ventilation, pollutants can build up and lead to poor air quality.


Consider opening windows on mild days to allow fresh air to circulate, or use your kitchen and bathroom exhaust fans to vent out stale air. You can also invest in an energy recovery ventilator (ERV), which brings fresh air into your home without compromising energy efficiency.


Tip: If you’re looking for a long-term ventilation solution, contact Don’s Heating and Cooling to learn more about ventilation systems and how they can improve your home’s air quality.
