Why Is My Air Conditioner Blowing Warm Air?

If you own a whole-house air conditioning system, you expect it to work day-in and day-out. Subpar performance is simply not an option, especially considering the rising cost of electricity these days. Coming home to find that warm air is blowing through your ducts when you’re calling for cooling can be awfully frustrating. Not only is your AC not working, but it’s actually making your home warmer. At the first sign of a problem, you need to get on the horn and call your local HVAC technician to come take a look. For air conditioning repair services in Bellevue, call Fort Collins Heating & Air Conditioning. We can diagnose the issue accurately and provide a viable solution.

There are several possible reasons why your AC is blowing warm instead of cool air. Before you pick up the phone, however, you need to make sure that your thermostat is properly adjusted. It may have accidentally been switched or adjusted to the wrong temperature.

  • Thermostat fault. If, after checking it, you find that it is indeed correctly set, then there could be a problem with your thermostat’s operation. It may not be assessing the temperature correctly, and it cannot, therefore, communicate with the control board effectively.
  • Dirty coils. The refrigerant cycle is based on the ability of your coils to absorb and dissipate thermal energy. The outdoor unit contains condenser coils that disperse heat into the outside air by means of an exhaust fan. However, if they become dirty, then they can no longer do this effectively and you may find warm air blowing through the ducts.
  • Low refrigerant. Your air conditioning system relies on a set level of refrigerant flowing through its coils and compressor. If this level drops, then all sorts of problems can occur, including warm air. The primary cause of low refrigerant is a leak. This may be because of a puncture or corrosion.

Let one of the Bellevue air conditioning repair technicians at Fort Collins Heating & Air Conditioning come take a look at your AC if it blows warm air.
