Why Is My Air Conditioner Blowing Warm Air?

AC Repair Detroit MI

One of the most dreadful experiences for homeowners is when they discover that their air conditioner is blowing warm air. Homeowners who find their air conditioner malfunctioning quickly become uncomfortable as temperatures rise inside the home and because they know that the repair could be costly. 

 

There are several reasons why air conditioners will blow warm air. Sometimes there is a leak in the air conditioner, causing the refrigerant to escape. When the coolant escapes, the motor will continue to propel the fans and warm air will permeate the home. This problem always necessitates a professional AC repair technician to add coolant as the chemicals are highly regulated by the Environmental Protection Agency.

 

Warm air can also emerge from the ducts when the unit is underpowered. This air is usually somewhat cool, but could also be described as somewhat warm. If you think there might be a power related problem, you can unplug the air condenser outside (the plug is usually on the exterior of your home behind the condenser). Wait about 10 seconds and plug the unit back in. Sometimes, this will reset the system. Also, go to your circuit breaker to see if perhaps the furnace or air conditioner has somehow tripped the system. If it looks like they are both in the ON position, it is acceptable to turn them OFF and then ON again. This can also perform a hard reset.

 

One of the most common reasons warm air comes out of the vents is the failure to change the air filter in a timely fashion. While different manufacturers have different recommendations for their products and the timeline for changing the air filters, it is generally wise to change the filter monthly. Dirty air filters, especially very dirty air filters, can restrict air flow, preventing air from becoming cool.
