What does an annual HVAC tune-up actually include?
A professional AC tune-up includes refrigerant level verification, coil cleaning, capacitor and contactor testing, motor amp draw check, thermostat calibration, condensate drain flush, and a written performance report. A furnace inspection covers heat exchanger inspection, ignition system test, burner cleaning, flue and venting check, and airflow measurement. AIRONE technicians complete both visits with a written report left with the homeowner after every appointment.
