Air Filters Be Changed in an AC System

The air conditioning system in your home has a filter upstream of the evaporator coil that removes particles from the conditioned air. This is a disposable or reusable filter and it can either be found in the return grille of your air conditioning unit or in special slots in the ductwork. The filter is usually a fuzzy or flat paper filter that can range in size from 1 to 3 inches. Most experts recommend a monthly check-in to make sure the air filter is in good shape and not clogged with dust, allergens or pet hair.

The type of filter you have and how people in the house use the air conditioner will determine how often it should be changed. For more information, if you have a family with asthma or allergies, the air filter will need to be replaced more frequently than in a household that has no one suffering from respiratory conditions. The number of people living in the house also factors into this because more bodies create more dust and debris, which can clog an air filter faster.

In addition, the geographic location of your home and the seasonality of the climate will impact the amount of dirt and dust that accumulates on an air filter, which can then lead to it needing to be changed more frequently. People living in desert climates, for instance, will likely need to change their filters more frequently because of the increased level of sand and dust in the air.

How Often Should Air Filters Be Changed in an AC System?

As the air filter becomes loaded with particles, it begins to reduce its efficiency and restricts airflow through the AC system. This causes the air conditioning to work overtime to compensate and can result in a higher energy bill. When a homeowner notices that their energy bills have gone up or they see excess dust collecting in the air vents, it is time to change the filter.

To change the filter, start by removing the old one and then find a new replacement. The old filter should have the size printed on it, so take a picture with your phone or write down the size to make sure you buy a proper-sized replacement. Once you have the correct filter, screw or snap it into place and then replace the cover or grille over the filter.

Before you finish, remember to write down the date on the new filter so you know when it is due to be changed again. You can even set a reminder on your phone for the same day of the month to ensure you never forget. By following these simple steps, you can make sure your air filter is always in the best condition and that your family is breathing clean, healthy air.
