Why Is Your AC Supplying Warm Air? 4 Common Causes
When the air is hot and humid, you cannot wait to turn on your AC, relax and enjoy the cool comfort. However, sometimes you can turn on your AC during a hot day when you feel sweaty, only to be hit by warm air. Well, this can be an incredibly frustrating situation since you count on your AC to offer you relief from the tormenting heat. But what could be causing this? This article will answer your question by highlighting four reasons your AC could be circulating warm air.
1. Dirty Filter
The air filter is tasked with preventing dust, dirt, and particles from the air from entering the AC. If it is clogged, airflow to the AC may be reduced. And the evaporator coil will not get enough warm air, making it freeze. A frozen evaporator coil cannot absorb heat from the air effectively, which could be why you are getting warm air. You may also note an increase in your power consumption because your AC will be overworking. Therefore, seek AC repair services to replace the filters ASAP.
2. A Faulty Compressor
Do you know the role of a compressor in your air conditioning? The compressor pushes the refrigerant through your unit and pressurizes it to release the heat it has absorbed from the air inside. If the compressor is damaged, it will no longer be able to pressurize the refrigerant, and the air coming from your AC will be warm instead of cool. However, an AC repair expert can inspect your compressor and fix it accordingly.
3. Refrigerant Leak
The refrigerant in the evaporator coil is the one that sucks heat from the interior air and directs it outside. If the evaporator coil is leaky, the remaining refrigerant may not adequately absorb the heat from the air, meaning you will likely get warm air from your AC. The AC repair contractor will seal the leaks and refill the refrigerant to restore your system efficiency.
4. Duct Leaks
The AC ducts supply conditioned air throughout your home. If the ducts have holes, the warm air in your home may enter and raise the temperature of the cooled air, leading to a warm air supply. Besides eliminating the warm air supply, fixing the leak may decrease your energy consumption because your AC won't have to work as hard.
If you are stuck with an AC blowing warm air, now you know what could be the culprit. Contact a local air conditioning repair technician to have your unit inspected. They will fix the problems to ensure your unit offers you and your family the comfort you bought it for.
