Air conditioners cool indoor spaces by moving heat outside and returning the cooled air inside. Thus, if your AC stops working properly, you may start feeling the heat inside your home. This can put you and your family at risk of heat-related illnesses during the hottest days of the year.

To be able to fix your AC correctly, you need to identify first the root cause of the problem. Here are the top 3 reasons why your air conditioner is not cooling your indoors:

Incorrect thermostat setting

If your AC is blowing warm air instead of cold air, the first step you should take is to check your thermostat settings. Make sure to set the device to cool. The U.S. Department of Energy suggests setting your thermostat to 78°F (26°C) only when you need cooling and setting it higher when you’re away to save cooling costs in summer.

Clogged air filter

Your AC air filters help clean the air in your home by trapping harmful contaminants, like dust, dirt, pollen, mold, and pet dander. Over time, your filters get clogged, restricting the flow of cold air. You can prevent this from happening by cleaning your air filters regularly. Changing of air filters should be done every 30 to 90 days.

Refrigerant leak

When your air conditioner is low on refrigerant, you may get warm air when you want it cold. A refrigerant leak is a serious AC problem and should only be handled by professionals. If you suspect a refrigerant leak in your home, turn off your AC first, then call for an emergency air conditioning repair.

If your air conditioner has problems that are not safe to fix on your own, do not hesitate to ask for help from a reputable HVAC company. Get your AC back running smoothly again by hiring a professional repair service now!
