Why Is My AC Blowing Out Warm Air?

Imagine that you come home after a hot, long day outdoors, but know for certain that you left the AC running on its regular program. Now imagine that you enter your home, only to find that it is marginally, if at all, cooler than the environment outdoors. That is cause for serious concern, not to mention considerable aggravation.

There are a number of different reasons as to why your air conditioner may blow hot air out of its ducts. Some are, of course, more serious than others. Read on, and remember to dial our number if you need any air conditioning services in Columbia, SC.

  • Thermostat issues are a common cause of warm air blowing from vents in one’s home. There are a few potential issues that you could be dealing with here. First and foremost, you may indeed have a malfunctioning thermostat that will require professional repairs or a replacement. However, it is also possible that you simply have set your thermostat incorrectly, with the temperature too high to sufficiently cool your home. Furthermore, it’s possible that it has been accidentally switched to the “fan only” mode.
  • Ice on the evaporator coil could also result in your system blowing warm air. If you have ice on your evaporator coil, your system may struggle to absorb a sufficient amount of heat from the air surrounding it, as the ice actually serves to insulate the coil. Ice on your evaporator coil could indicate that you have a very dirty air filter restricting airflow. It could also be a symptom of another, more serious problem, though.
  • Refrigerant leaks can lead to ice forming on the coil, as well. Of course, even if there isn’t ice on the coil, refrigerant leaks can still seriously impede the operation of your system. If there is not enough refrigerant in your air conditioning system, it will struggle to effectively remove the right amount of heat from the air in your home.
