Why is My Air Conditioner Always Running?

Cincinnati’s hot, humid summers mean your air conditioner will get a workout keeping you cool. However, that doesn’t mean it should always be running. If you’ve been asking, “Why is my air conditioner always running?” here are a few things to check.

Air Filters and Fan Blades

The first thing to do is make sure your ac unit is clean. Clean or replace the filters and make sure the fan blades are not coated with a layer of grime. Dirt can cause your blower motor or fans to not run properly and cause your ac to run all the time. A good cleaning helps your unit run at peak efficiency.

Air Conditioner Coils

If you didn’t have your air conditioner serviced before summer hit, you may have dirty indoor and outdoor coils or a low refrigerant charge. This is especially true if it is running all the time but the AC is not cold enough to cool the room properly. In this case, it is best to give the air conditioning professionals a call. They can quickly solve your problem.

Size of Air Conditioner

Another issue is that your air conditioner may not be properly sized for your home. Depending on your climate, most air conditioning systems are designed with a 20 degree differential. Which means, if it is 100 degrees, your air conditioner is performing properly if it maintains 80 degrees in your home. If your thermostat is set at 75 degrees, your air conditioner cannot reach that level, which means it just runs all day. You may need a larger system and some ductwork modifications for your home.

Summer in Cincinnati can get especially hot with an average temperature of can reach 83-93 degrees.
