What Is Included in a Typical AC Tune Up Service?

A typical AC tune-up service includes inspection, cleaning, testing, and calibration to restore efficient, reliable cooling and reduce breakdown risk. The most common issues we prevent are airflow restrictions and coil fouling, which drive up energy use and stress the compressor. Our technicians service homes around Lancaster with a consistent checklist that targets performance, safety, and indoor air quality; a thin film on the outdoor coil can raise system pressure more than most homeowners realize.

• Measure refrigerant levels/pressures and run a full system performance test
• Clean condenser coils; lubricate moving parts; verify blower and motor operation
• Tighten electrical connections; check the control board; test and recalibrate the thermostat
• Clear the condensate drain; replace or clean the air filter; check ductwork, airflow, and supply temperatures

Turn the system off at the breaker and schedule service if you see ice on the refrigerant lines or water pooling at the air handler.
