AC Blowing Warm Air? 7 Common Causes in Denver Homes
When your AC blows warm air instead of cold, it's frustrating — especially during a Denver summer. Here are the 7 most common causes.
7 Causes of AC Blowing Warm Air
- Incorrect Thermostat Settings — Ensure set to "cool" and fan on "auto."
- Dirty Air Filter — A clogged filter restricts airflow.
- Refrigerant Leak — Low refrigerant means reduced cooling.
- Frozen Evaporator Coil — Often caused by dirty filter or low refrigerant.
- Electrical Issues — A tripped breaker can shut down the outdoor unit.
