Why Is My AC Not Blowing Cool Air?

Air is blowing out of your air conditioner, but it’s not cool. And unless you’ve intentionally switched the setting to heat, that’s a problem.

There’s a list of reasons why your AC may not be producing cool air and many of them are an easy fix. While the solution may be as simple as adjusting your thermostat, bigger issues call for the expertise of an air conditioning technician. Here’s a guide to help you discover what’s keeping your AC from doing its job and how you can restore your home’s comfort.

Reasons Your AC Isn’t Blowing Cool Air

Thermostat setting: It may seem like a no-brainer, but the wrong thermostat setting can easily lead to a hot house. If you find that your air conditioner is constantly running and alternates between blowing cool air and warm air, it may be because your thermostat is switched to “on” instead of “auto.” In the “on” position, your thermostat will trigger your air conditioner to run even when your home does not need to be cooled, thus, causing it to produce warm air. Switching it back to “auto” should do the trick.

Also, just to be safe, check that your thermostat is set to “cool” and not “heat.” You never know if someone may have accidentally hit the switch.

Dirty air filter: A dirty filter can be the cause of various air conditioning woes, including this one. If the airflow coming out of your vents seems weak and is not as cool as it should be, it may be time to change the filter. If too much dirt, dust and other airborne particles are allowed to build up in a filter, the clog will restrict airflow, decreasing your AC’s overall efficiency. Check your filter to see if it’s full, and if so, replace it! Keep in mind that to get the most out of your AC, you should replace the air filter every month.

Condenser unit issues: Check your system’s condenser unit, which is located outside. If the fan is not working properly, your system won’t be able to produce cool air. A professional technician will need to perform a repair. If the fan is working properly, take note of the area surrounding the condenser. Are there leaves, twigs or other pieces of debris covering it? Wipe them away. Also, make sure there is a buffer of at least two feet between the condenser and any trees or shrubs growing in your yard.

Low refrigerant: Your AC may not be blowing cold air if its refrigerant level is lacking. However, since air conditioners do not actually consume refrigerant, low levels are the result of a leak. If your suspect a refrigerant leak, call an AC professional for a repair right away.
