One of the most frustrating problems a homeowner can experience during a hot Delaware summer is an air conditioner that blows warm air. There are several possible causes for this issue, and some you may be able to address yourself before calling a technician.
Common Causes of Warm Air from Your AC
- Incorrect thermostat setting: Check that the thermostat is set to “cool” and the temperature is set below room temperature
- Dirty air filter: A clogged filter restricts airflow and can cause the system to overheat
- Low refrigerant: If your system is low on refrigerant, it can’t properly absorb heat from your home
- Frozen evaporator coil: Ice buildup on the coil prevents proper heat exchange
- Compressor failure: A faulty compressor can’t pump refrigerant properly
- Dirty condenser coils: Outdoor unit debris buildup reduces efficiency
