Air Filters and How They Impact Your HVAC Performance

man-holding-air-filter

Do you know why HVAC professionals tell you to change your systems’ air filters every 1-3 months? The answer may surprise you. Homeowners often assume that the reason a dirty air filter is a problem is due to poor indoor air quality and that this is the reason we tell you to clean or replace it. This is partially true, but definitely not the whole story.

This air filter is in place to do much more than preventing allergens from moving back into your home’s airstream. It blocks particles from damaging the inside of your air conditioner by pummeling the components or jamming the fan. When an air filter is too clogged up though, it can do just as much damage to your HVAC performance, requiring you to need unexpected air conditioning services. Of course, we’re here for those services! But we’d like to help you avoid preventable problems like the ones we’ve outlined below.

Reduced Comfort

Your air filter might seem like a very small component of your home comfort system, but looks can be deceiving! This air filter is located between the intake air register and your HVAC system. A clogged filter prevents air from being drawn into your air conditioner. As a result, airflow is reduced. You may notice hot spots throughout your home, leading to decreased comfort no matter how low you set the thermostat.

Air Conditioner Leakage

Cooling systems function by absorbing heat from the air within your home. As refrigerant evaporates in the indoor evaporator coil, it is able to absorb heat from the air blowing over the coil. If the air filter is clogged, however, that warm air is absent from the process which could cause the coil to freeze over.

As the coil thaws down, it can cause water to leak into your home, causing property damage. A frozen coil is a sure sign of a problem. While it may be due to a different issue than your air filter, it must be managed by a professional as trying to remove ice on your own can lead to unintentional system damage.

Higher Than Average Utility Bills

Your AC blower fan has to work harder to bring in the right amount of air when you have a clogged air filter. Changing the air filter on a regular basis is one of the easiest ways to lower your monthly utility bills.

Potentially Damaged HVAC System

Your air conditioner, and your forced-air heater for that matter, were designed to take in a certain amount of air each time it cycles. When airflow suffers due to a clogged air filter, the components of the system have to work a lot harder to do their jobs. This means you can expect a lot of wear and tear over the season, and your HVAC system might fail you when you need it the most.
