Preventive maintenance is a good investment and it is your assurance that your HVAC system will function properly. On a regular basis, heat pumps and air conditioners should have a tune-up by professionals. Gas-fired equipment function with greater efficiency should be maintained every other year. Inspections on boiler and furnace systems should include 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.
Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils and refrigerant lines. It is required to ensure compliance to relevant standards and is an essential services code requirement.
