Now that we’re knee-deep in summer, it seems like the only reprieve from the heat and humidity is inside of our cool, climate-controlled homes.

Your air conditioner may be the only thing that stands between you and sweating in your living room, but did you know that air conditioners are not designed to run constantly?

In fact, if your air conditioner never shuts off, it may be a sign of one of these five problems.

Apply scented extract to a return air filter to help reduce musty odors.

1. Your air filter is clogged.

When it comes to your air conditioner’s efficiency, circulation is the key. All of the dust and debris in a dirty air filter keeps your air conditioner from receiving the air flow it needs to cool effectively and then turn off.

Change your filter according to the manufacturer’s directions, usually once every 30-90 days for maximum airflow.

Bonus: A clean air filter will keep dust and allergens from infiltrating your house.

2. You are running low on refrigerant.

Your air conditioner requires refrigerant to cool the evaporator coils. As your unit ages, leaks are likely to develop, causing refrigerant levels to drop.

In some cases, these leaks are slow enough that recharging your refrigerant level is all it takes to beef up your air conditioner cooling capacity.

Fortunately, most HVAC specialists do this as a part of your annual maintenance package.
