Your AC can run but not cool due to a clogged filter, dirty outdoor coil, low refrigerant, a failing capacitor, or thermostat/settings issues. In Roanoke and Cave Spring homes, blocked returns or a frozen indoor coil are also common.
Quick checks:
- Set thermostat to Cool and lower the setpoint.
- Replace or clean the air filter.
- Clear debris around the outdoor unit.
- Check the breaker and condensate drain.
- If you see ice on lines, turn AC Off, Fan On, and call a pro.
