Is a Dirty Air Filter Really That Serious?

dirty-air-filter_1416598855.jpgYou take a look at the air filter you have in your Cleveland home and see that it's a bit dusty and appears to be in need of replacement, but you close the door and tell yourself it's just an air filter and not all that important. After all, your system seems to be working just fine. Unfortunately, this is a common response when homeowners discover that they have a dirty air filter, and it really is a big deal when it comes to the health of your HVAC system.

It's no secret that a dirty filter can actually compromise indoor air quality with dust and allergens. However, this can actually be the least of your worries. Leaving a dirty filter in place can cause damage to the system in a couple of different ways.

The air conditioner relies on returned air through the filtration system that's warm enough to keep the coils from freezing up. If no air is able to be pulled through the filter because it's clogged, this can can freeze the entire system and actually prevent cool air from being sent out through the ductwork as it should be.

When it comes to the heating system, or heat pump, it relies just as much on clear air circulation through the filters as the A/C. A dirty air filter will actually prevent the HVAC system from heating your home. The clogged air filter will prevent warm air from flowing, which will cause overheating. Most systems are designed to switch burners off when the temperature becomes to high. This means that the blower may continue to run, but no heat will be coming through the vents.

A clogged filter will also put undue strain on your system blower or fan.  In some cases this can lead to motor failure and a potentially costly repair.  In any event, it will cause the unit to draw motor power and raise you electric bill.

Prolonged use of dirty air filters can cause serious issues with your home's HVAC system. Therefore, it's imperative to keep close tabs on the filter being used. If you'd like more information about repairing issues caused by dirty air filters, contact P.K. Wadsworth Heating & Cooling.
