Why Are Filters so Important for Your Furnace?

Your furnace filter is a critical element of your HVAC system. It performs an important job, especially during the coldest months of the year.


Your furnace filter helps keep clean air circulating through your home. That's one reason why you want to change the filter whenever it's dirty.


The best air furnace filter is the one that's right for your home. Here's a look at the importance of furnace filters for heating your home.


Furnace Filters Help Remove Pollutants from Your Home

The number one job of an air filter is to filter air. Furnace filters are made to capture and trap dirt, dust, pet dander, smog, and mould spores.


If your furnace filter is clogged, it becomes useless for trapping indoor allergens and dirty air particles. A dirty filter can make the air quality of your home worse.


If you're concerned about the air quality, be sure to choose a filter with a high minimum efficiency reporting value (MERV). This ranges from 1 to 12, and the higher the number, the better it filters the air.


Extend the Life of Your HVAC 

An HVAC unit is expensive. You don't want to have to replace it unless it's necessary. You can extend the life of your system by replacing the furnace filter regularly.


A dirty filter is a common cause of system breakdowns. When air can't pass through and the filter is clogged, it can cause the system to overheat. 


That makes the motor work harder to heat your home, and it can lead to costly repairs or even system failure.


Keep Energy Costs Down

No one wants to see their energy bills creeping up month after month. You can help keep energy costs down if you change your furnace filters on a regular basis.


When your filter is clogged and not filtering as it should, the system requires more energy to run. This drives up your energy bills.


Maintaining your furnace and changing the filter can help you save some energy dollars. Talk to an HVAC pro to make sure you're using the best furnace filter for your HVAC system.


Lower the Chances of a Dangerous Scenario

Although rare, a dirty, clogged furnace filter can be dangerous. When the filter is dirty, it isn't efficient. The HVAC system must work harder to accomplish the job of heating and cooling.


A dirty filter can cause a problem called short-cycling. This can cause the furnace to turn off before it should.


An overworked heating unit can lead to a fire. Be sure to get regular HVAC maintenance and change your furnace filters to avoid this possibility.
