If you’ve ever talked to one of our HVAC professionals about the air filter in your system, then you’ve likely been advised to change it out every month or so–less often if it is a higher quality air filter (maybe every 3 months).
You’ve likely assumed that the reason we recommend this is to improve your overall indoor air quality. We understand why this assumption is made, but it’s actually a little misguided. While whole-house air purifiers and air filtration systems are designed to improve your indoor air quality, the standard HVAC air filter has a different purpose.
Rather than being there to protect your air quality, it’s in place to protect the HVAC system itself from dust, dirt, and other debris that can get inside and damage its sensitive components, and therefore negatively impact the performance of the system.
This is why it’s so important to change out the air filter regularly. Read on to learn more.
Dirty Air Filter = Less Comfort
Your air filter seems like a really small and unimportant component, but it actually has a really important job. This air filter rests between your HVAC system and the intake air. A clogged air filter restricts air from coming into your air conditioner.
As a result, you won’t have enough air getting back into your home to keep you cool (or warm, in the case of a furnace!) When your home experiences uneven temperatures or if the temperature doesn’t seem to match your thermostat, a clogged air filter can absolutely be the culprit. And that’s not all that happens.
You Might Experience AC Leakage
Air conditioning systems operate by absorbing heat from the air within your living space. As refrigerant flows through the evaporator coil it absorbs the heat from the air blowing over the coil. If your air filter is too blocked up, warm air is limited, which can cause the coil to freeze.
Not only can this prevent the evaporator coil from absorbing heat like it’s meant to, but as this ice thaws out, it creates more moisture than your air conditioner’s condensate drain or condensate pan can handle. As a result, you’ll see water leakage, which can damage your property.
If you even do see ice forming on your air conditioner, it’s important that you call in a pro right away. Trying to chip away at it on your own can ultimately damage your air conditioner further. Thawing it on your own won’t resolve the root of the problem. If you do change the air filter and notice that the ice goes away, be alert to any leakage that may occur afterward!
