Why Is My AC Running But Not Cooling Properly?
Your AC is running but not cooling because of airflow restrictions or a refrigeration issue. Common causes include a dirty filter, a blocked outdoor coil, an iced evaporator coil, low refrigerant, thermostat setting problems, or duct leaks. We provide AC repair and maintenance with an on-site assessment and upfront pricing in Denver, Highlands Ranch, and nearby. Seasonal tune-ups help prevent many issues.
- Set the thermostat to Cool and Auto.
- Replace a dirty air filter.
- Clear debris from the outdoor unit; if you see ice, turn the system off to thaw.
