Your AC may run without cooling because of airflow restrictions, low refrigerant, or duct leaks. Dirty filters, clogged coils, failed capacitors, wiring faults, or thermostat/heat-pump problems can also reduce cooling. We provide on-site diagnostics and repair across Knoxville and Farragut. Technicians inspect coils, refrigerant charge, capacitors, wiring, drain lines, ducts, and thermostat, then fix the issue.
- Replace the air filter.
- Set thermostat to Cool and 3°F lower.
- Ensure supply vents are open and returns clear.
