Why Is My Air Conditioner Running But Not Cooling Properly?
Your AC can run but not cool if it has low refrigerant, a failing compressor, a broken condenser fan, drainage problems, or electrical/thermostat faults. Our NATE-certified technicians diagnose and fix these issues, and we offer 24/7 emergency service across Southwest Virginia, including Roanoke and Rocky Mount.
Quick checks:
- Set thermostat to Cool and lower it 3–5°F.
- Replace a dirty filter.
- Clear debris around the outdoor unit.
- If you see ice or water at the air handler, turn the system off and call.
