How to Know the Right Size Air Filter for Your Home

Taking the confusion out of heating and air conditioning air filters.

You know that your heating and air conditioning system needs some TLC in between twice-yearly service calls, but what exactly does that TLC consist of? Two words: air filters. Read on for everything you need to know, including how to get the right size air filter for your home.

What Does an Air Filter Do in My HVAC System?

Many people assume that HVAC air filters keep dust and other airborne pollutants from circulating through your home. While this is definitely true, and it can have a significant impact on your indoor air quality, the air filter's primary job is to protect your heating and cooling equipment.

As it pulls air into the system through air return vents, that air passes through the filter before the HVAC system cools or heats it. The filter catches and traps dust, dirt, mildew, dander, debris, and other contaminants before they can get into the equipment. This helps keep all of that junk out of the unit and helps keep it running as it should, preventing issues and malfunctions in the process.

How Do I Know the Right Size Air Filter for My Home?

Buying the right size air filter for your HVAC system is critical to it functioning properly. The easiest way to tell what filter size you need is by looking at the owner's manual for your heating and cooling system. It will give you the length and width, along with the type of filter that will work best for your brand and system. Air filters are often quite simple to remove and replace. Your manual will show you just how to do it.

Changing your HVAC air filter in between regular maintenance is the key to an effective and efficient system. For everything you need to know about choosing the right air filter for your heating and air conditioning system, contact our team at H.H. Hovey Heating and Cooling.
