Heat Pump Advantage – One advantage is they save on energy thus generating lower energy bills. Disadvantage – In very cold climates a back up system may be needed to effectively heat the home. Compressor and Condenser The air conditioner compressor pumps cool refrigerant vapor from the air conditioner evaporator and compresses the vapor. The air conditioner condenser coils receive the hot vapor from the compressor and immediately the air conditioner compressor begins to condense the refrigerant into a liquid by removing heat from the hot vapor
Heat Pump Air Handling Unit The Air Handling Unit circulates conditioned air throughout the home.
Insulation The purpose of insulation is to limit the transfer of heat. Blanket Insulation
