AC FAQ: Why Is My Air Conditioner Blowing Warm Air?

To say that the heat of summer in this part of the country is intense is to make a massive understatement. When temperatures soar, you need to know that your home cooling system is functioning precisely as it ought to. If you enter your home, only to find that it is hardly any cooler than the environment outdoors, this is obviously not the case. If your air conditioner in Miami, FL is blowing hot air into your living space, dial our number to schedule prompt air conditioner repair services.

Potential Causes of the Problem

While most issues are going to require the repair services of a trained professional, some can actually be resolved on your own. Read the following list of potential causes of the issue, and dial our number to ask any questions that you may have.

  • Dirty filter – This one won’t actually require the services of a trained professional. You just need to be more diligent in changing out your AC filter (though we can certainly show you how to do so if you are unsure). When your filter is very dirty, it can impede airflow throughout the system. This can cause the evaporator coil to get too cold, which can lead to icing. When that happens, it is further insulated, which cuts down on cooling capacity.
  • Thermostat issues – Problems with your thermostat may or may not require professional intervention, depending upon the nature of the problem. It’s possible that your thermostat is just set wrong, or that it was accidentally switched to “fan only”. If this is the case, you can adjust it on your own. However, if your thermostat is actually registering/regulating temperatures wrong, it will need to be professionally repaired/replaced.
  • Refrigerant leaks – This is a big one. If your system is leaking refrigerant, it can lead to the aforementioned icing of the evaporator coil. Even if ice does not develop, though, the low refrigerant level will make it impossible for your system to cool the air in your home successfully.
