Why Is My AC Running But Not Blowing Cold Air?
Your AC can run but stop cooling due to a dirty filter, low refrigerant, a dirty outdoor coil, wrong thermostat mode, a tripped outdoor breaker, or a failed blower/capacitor. Sierra offers same-day service and 24/7 emergency help, and we stock parts to complete 93% of repairs on the spot.
Quick checks:
- Set thermostat to Cool and fan to Auto.
- Replace or clean the air filter.
- Clear debris around the outdoor unit.
- Verify the outdoor disconnect/breaker is on.
