HVAC Maintenance

High-quality heating and air conditioning equipment is manufactured to be rugged and dependable through many years of service. However, critical system components experience substantial operational stress, especially during extreme temperatures. A modern furnace or air conditioner requires periodic, routine maintenance to maximize indoor comfort, minimize operating costs, and avoid unexpected failures.

Services for Maintenance Customers

Annual HVAC maintenance for residential and commercial systems helps ensure that the equipment continues to perform according to the manufacturer’s specifications. Our factory trained technicians use a variety of high-tech diagnostic tools to uncover systemic problems before a unit actually fails.

Annual tune-up packages provide comprehensive testing of vital furnace and air conditioning components including the blower, heat exchanger, ignition system, burners, circuit boards, contactors, defrost controls, fan motor, and the compressor. We also check refrigerant levels and record the temperature drop across the coil.

Other important HVAC services include recalibrating the thermostat, measuring volts and amps on motors, testing the flue, cleaning the evaporator and condensing coils, changing filters, and recalibrating the system for optimal performance.
