What’s Making My AC System in Chelsea, AL, Blow Warm Air?

Summer’s hot weather makes air conditioning a necessity in Chelsea, AL. When your AC system malfunctions, it produces warm instead of cold air. We’ll explain some possible reasons your AC system is blowing warm air.

Thermostat Issues

The thermostat is the house’s control center for the AC system. If the thermostat is malfunctioning or not set appropriately, the AC system blows unwelcome warm air. Make sure the thermostat is operating in COOL mode and the setting is below the current room temperature.

Dirty Air Filters

Air filters are critical for maintaining proper air circulation and preventing the accumulation of contaminants in your AC system. As you cool your home, excessive dust fills the filters, hindering airflow and causing the system to stir hot air. Change your air filter every one to three months to avoid this issue.

Refrigerant Leaks

Your AC uses refrigerant to absorb heat and cool the air in your home. Refrigerant leaks in the lines prevent air cooling. Symptoms of a refrigerant leak include squealing, squeaking or hissing noises from the HVAC system, ice buildup on the refrigerant line and poor cooling performance.

Frozen Evaporator Coils

Another factor that may lead to warm air is frozen evaporator coils. Restricted airflow causes the coils to freeze or lead to poor performance in the air conditioner. If you see that ice has formed on your indoor unit, switch off the AC system and let it melt.

Electrical Problems

Faulty electrical work contributes to the problem of the AC system blowing warm air. Position your circuit breakers correctly so that none of them is likely to trip.
