How’s the air in your home? How high is your electric bill during the hottest part of the Hillsborough County summer?

If you haven’t changed your filter in a while, your air conditioner could be sending dirty air through your air ducts. You’re also increasing your energy costs by forcing your air conditioner to work harder to push air throughout your home.

Changing your A/C filter should be a regular habit. With routine air filter maintenance, you can lower your home’s energy use between 5-15%.

Don’t make the mistake of neglecting to maintain your air conditioner. Changing the filter is a simple task you can do yourself.

Here’s how to change air conditioning filters.

Find the Filter

This might seem obvious. But the first step to replacing your filter is knowing where it is.

If you have central air, the filter is in the indoor part of your air-conditioning system. You’ll usually find it in a closet near your thermostat.

Your filter sits located behind a small panel. There should be a latch or small screw to keep the door closed over the filter.

If you have individual room A/C units, you’ll find the filter directly behind the vent grate.

Open the door or remove the vent to check the filter. If the filter fibers are gray (or darker), it’s time to change the filter for a clean one.

Know the Right Size and Type

Air conditioner filters are not one-size-fits-all. Before you get rid of the dirty filter, make sure you have a replacement that’s the right size.

Using the wrong size filter can harm the air quality in your home. This can also cause your air conditioning unit to break.

Filter sizes range from one to six inches thick in depth. You’ll find your filter’s depth, width, and length printed on the edge of the old filter.

Look for numbers in this format to determine the size of your filter: 14 x 25 x 1.

You’ll also see a MERV (Minimum Efficiency Reporting Value) rating on the filter. Filters with a low MERV rating remove fewer particles from the air than filters with higher MERV ratings.

If you suffer from allergies, asthma, or your home has pet dander, use a filter with a higher MERV rating to improve your indoor air quality.

Replace the Filter

After you remove the old, dirty filter, slide the new filter in its place. Make sure the arrow on the filter points toward the duct.

If the filter points the wrong way, this restricts airflow to the unit.

Replace the cover over the filter. Secure the fasteners.

A Clean A/C Filter is Good For Your Health

Regularly changing your A/C filter helps you breathe better in your home.

In addition to keeping clean filters in your unit, be sure you schedule a technician for annual air-conditioning maintenance. They’ll clean your a/c and make sure everything works well before the summer heat arrives.
