What To Do If Your Air Conditioner Blows Out Warm Air

What To Do If The Warm Air Output From Your Air Conditioner

During the humid summer months, air conditioners give much-needed thermal comfort. Air conditioners, in particular, help to keep the room at a reasonable temperature. They also aid in the removal of airborne contaminants. When your air conditioner works harder and longer in the heat, it is more prone to breakdowns. Here are some possible causes of your air conditioner not cooling or spewing hot air:

  • The thermostat might inaccurately set to heat
  • A dirty air filter could be causing a dirty evaporator coil.
  • The condenser coil may get clogged.
  • You could be low on refrigerant, sometimes known as freon.

So to avoid problems, your air conditioner, like all other appliances, must be maintained and cleaned regularly. This way, you might never have to deal with a hot air AC unit again during the summer. The above-discussed issues can get solved without much fuss. And here’s how to do that:

  • Dirty Air Filters

If the air filter in your cooling device is unclean, it won’t be able to move cool air through the system efficiently. It puts a burden on your unit, potentially causing it to blow warm air. Check the air filter to see if it’s dirty when trying to figure out why your air conditioner isn’t operating properly. Hence if this is the case, replace it with a new clean filter, or you can even call a professional and have it cleaned, then see if the warm air problem goes away. 

  • Thermostat Malfunctions

One of the primary things you should check is the thermostat, which may seem apparent. If your air conditioner blasts hot air, the thermostat may remain set to heat by mistake. Set the thermostat to chilly and wait for the air conditioner to start blowing cool air. Also, it is better to double-check that the thermostat batteries are in good functioning and that the temperature is not too high.

  • Lack of Electricity

Another explanation could be a lack of electricity in a split air conditioning system. Also, if the power to your house is cut off, only the indoor components of your system work, resulting in warm air blowing through the vents. Check for electricity and, if necessary, reset your outdoor unit.

  • Refrigerant Leaks

Refrigerant leaks might potentially cause your air conditioner to blast hot air. When refrigerant leaks from the system, the unit lacks the necessary charge to complete cooling cycles, so the air you breathe is warmer than it should be. The easiest way to avoid these leaks is to schedule annual air conditioning inspections before the season starts.
