Why Do I Need To Change My Air Filter?

The humble air filter is the unsung hero of your HVAC system. It has the dirty job of catching dust, debris, and other contaminants before they reach your vents. Without it, your air would be filthy.

Here’s why you need to change it regularly.

Improves HVAC Performance

Filters simply trap indoor pollutants before they enter the air handler, keeping that unit clean. Yet filters only have so much surface area; when all of that is taken up with dirt, pollen, and so on, it restricts the circulation of air and forces the system to work harder. Its struggle to reach your desired temperature (called a setpoint) will be reflected in your utility bills.

All the while, the pollutants that the filters can no longer trap will enter the air handler and clog up the evaporator coil and other components. Dirt will hinder the coil's ability to absorb heat. Again, this means poor performance, higher bills, and additional wear and tear on the system.

Improves Indoor Air Quality

When asthma and allergy sufferers begin to suffer more than usual, it's wise to check the filters. Clogged filters allow all kinds of pollutants to float around in your home. The clogged materials themselves may become the perfect catalyst for mold growth, too. Besides replacing the filters, getting an air purifier or other indoor air quality products may be beneficial.

Improves Comfort

Clogged filters are one of the leading causes of uneven heating and cooling. It's simple: when airflow to a room is hindered, that room will always be cooler or warmer than you want it, causing discomfort. A clean filter will ensure all the rooms will reach your desired temperature.
