What services need to be performed for preventative maintenance on my heating and air conditioning equipment?
How often should this maintenance be performed? We recommend that you have preventative maintenance before or during the winter heating season and before or during the summer cooling season. Oliver offers service agreements that include reduced rates on labor and parts and provide priority response. Service/maintenance agreements include cleaning indoor and outdoor coils, tightening electrical connections, checking supply voltage and operating current, checking refrigerant charge, measuring temperature differential at supply and return registers, cleaning blower wheel and motor, inspecting and adjusting burner, checking heat exchangers, cleaning drain lines and pan, checking ductwork for leaks and insulation, and checking the thermostat.
