ABSTRACT:
A heating and/or cooling system for a dwelling, including a heat exchanger that is located indoors, and ducting that directs rejected air to the attic space or outdoors. The heat exchanger is pre-heated and/or pre-cooled with indoor space air, thereby increasing the efficiency of the system. Additionally, a pair of parallel heat exchangers are mounted in the air path of the air handler that forces air in the indoor space of the dwelling. The parallel heat exchangers are connected to conduit through which refrigerant flows between the first heat exchanger, a compressor and an expansion valve. The parallel heat exchangers are mounted in the air path, and because they are heated or cooled to the same extent, they heat or cool the air blowing through them to a greater extent than a conventional heating and cooling system.
