Why Is Warm Air Coming From My AC in West Ashley, SC?

When you turn on the air conditioner in your West Ashley, SC home, you expect cold air to come out of the vents. When warm or hot air comes out instead, you know you have a problem. Learn more about the possible causes of warm air coming from your AC below, so you know when to call our advanced technicians for help.

Thermostat Settings

If you aren’t getting cold air from your vents after turning on the air conditioner, first check your thermostat. Make sure you have flipped the switch to cool mode and that the temperature setting is low enough to require cold air.

Dirty Air Filter

Air filters trap dust and other contaminants to keep them out of your system and the circulating air. The filters require changing every three months or so. If debris is clogging the filter, your air conditioner may be unable to push cold air to the vents.

Frozen Coils

When your air conditioner is excessively dirty or experiencing a heat exchange issue, the evaporator coils may freeze. When this happens, the AC may be unable to create cold air, resulting in warm air blowing through the vents.

Low Refrigerant

Your air conditioner can’t create cold air without an adequate supply of refrigerant. If there is a leak, the refrigerant levels may be too low for cold air creation. Leaks are hazardous to personal safety and the environment and require immediate action.

Faulty Fan

A broken or malfunctioning fan inside your air conditioner can contribute to a lack of cold air. If the fan can’t push the cold air through the ducts, the air may warm back up before it slowly reaches the vents.

Having hot or warm air blowing out of your air conditioning vents will result in miserable conditions inside your home. For this problem, call AC Heating and Air Conditioning Services and let our technicians perform trusted AC repairs in your West Ashley, SC home.
