In a warm climate like that in Wellington, FL, air conditioners operate for at least six months of the year. A common but annoying problem you may experience is an AC system that blows warm air. In this article, learn about four possible reasons for hot air coming through your supply vents when running the air conditioner.

Thermostat Settings

Sometimes, warm air blowing when your air conditioner is running is due to something as simple as a thermostat that isn’t set properly. You may have it set to Heat instead of Cool, especially if there are young children in the home who may have touched it. Another common error is having the fan set to On instead of Auto, causing the system to blow air even when the AC system isn’t running.

Electrical Issues

It’s possible that the power to the outdoor portion of your AC system went out, but the indoor unit is still running. Without power to this portion of the system, air doesn’t get cooled but is still blown through the vents. Check the circuit breaker and call us if the problem pops up again.

Dirty Coil or Filter

Build-up of ice, grime, dirt or any other substance will affect your AC system’s performance. Change the filter and see if the problem resolves itself. If not, call a service technician to clean the outdoor coils for you.

Low Refrigerant Levels

Air conditioners utilize refrigerant in the cooling process. When levels get too low, the system is no longer able to absorb heat and remove it from the air. A leak is the most common cause of low refrigerant, making a tuneup or repair imminent.

If your air conditioner keeps blowing warm instead of cool air, it’s time to get it checked. Give us a call at North County Cooling Inc. to schedule an AC repair appointment today. We’ll be glad to send over a service technician as soon as possible.
