At least once a year heat pumps require a professional tune-up. Because gas-fired equipment functions with greater efficiency, it only needs to be serviced every other year. Professional tune-ups should include:
Inspections on boiler and furnace systems including ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank and every part of the actual furnace and boiler. The heat pump inspection should also include inspections of the fan, compressor, indoor coils, outdoor coils and refrigerant lines.
