At least once a year, we suggest that homeowners schedule a professional tune-up for the central heating and cooling system in their home. Inspections on boiler and furnace systems should include duct work, 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.
