An HVAC air filter works to trap dust and debris whenever your heating or air conditioning is running. The main purpose of the filter is to prevent any debris from damaging the blower fan and other components, but it also helps to improve air quality by filtering out pollen and other allergens and pollutants. You should always make sure to replace the filter every one to three months, and here is a guide on how to do it and why it’s important.

Locating and Replacing Your Air Filter

The location of your air filter can vary depending on what type of HVAC system you have. If you have a furnace and air conditioner, then the filter will be located inside the return duct just next to the furnace. If you instead use a heat pump, the filter will either be located inside the air handler cabinet or underneath the return-air vents.

Once you’ve located the filter, all you need to do is slide the old one and put the new filter in its place. When putting the new filter in, make sure that the arrows on it point in the direction that air flows through the system. If you have a furnace, the arrow should point toward the furnace. For filters inside a return vent, the arrows should point toward the duct and away from the vent cover.

What Happens If the Air Filter Isn’t Replaced Regularly?

If you go too long without replacing your air filter, it will become clogged to the point where very little air can flow through it. The less air that comes into the system, the less effective your heating and cooling will be. This will lead to higher energy costs and more wear and tear on all of your HVAC components. A clogged filter can also cause the evaporator coil to freeze up and prevent your AC from working at all. If the filter is clogged when your heat is on, it can lead to your furnace overheating which has the potential to cause serious damage.
