How Often Do I Need to Change My AC’s Air Filter?

One question our Certified Air Systems, Inc., experts get asked a lot is, “do I have to change my air filter?” The answer is unequivocally “yes!” Then comes the follow-up question: how often do I have to change it? The answer to this is also straight-forward: you should change your AC’s air filter every 3 months. If you have smokers and/or pets in your home, it should be every 2 months. But the last question is always the longer one to answer: “why do I need to change my air filter?” To answer this, we’ll list out some of the more common problems that can develop when you don’t change your system’s air filter regularly:

Low Air Volume

Your air conditioner is designed to deliver a specific amount of air so that you have the cooling you need. A clogged air filter will actually block the air flow, significantly reducing the amount of air flowing through your system. The result is less air reaching your living spaces.

Excess Stress Added to Your System

Your system has to fight the imbalance in the air flow caused by your clogged air filter. This forces your system to work harder, which adds excess wear and tear to the system.

Decreases Energy Usage

As your system works harder to achieve the level of cooling you need, it will consume more energy. You’ll see this extra usage in your monthly utility bill.

Icing on the Evaporator Coils

When the air flow is reduced in your system, the heat release/cooling process is directly affected. One sign of this is ice build-up on your evaporator coils. This isn’t normal and simply scraping off the ice does not fix the problem.
