Energy Conservation Program: Energy Conservation Standards for Packaged Terminal Air Conditioners and Packaged Terminal Heat Pumps

The Energy Policy and Conservation Act of 1975 (EPCA), as amended, prescribes energy conservation standards for various consumer products and certain commercial and industrial equipment, including packaged terminal air conditioner (PTAC) and packaged terminal heat pump (PTHP) equipment. EPCA requires the U.S. Department of Energy (DOE) to determine whether more-stringent standards for PTACs and PTHPs would be technologically feasible and economically justified, and would save a significant amount of energy. In this final rule, DOE is adopting amended energy conservation standards for PTACs equivalent to the PTAC standards in American National Standards Institute (ANSI)/ American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)/Illuminating Engineering Society (IES) Standard 90.1-2013. DOE is not amending the current energy conservation standards for PTHPs, which are already equivalent to the PTHP standards in ANSI/ASHRAE/IES Standard 90.1-2013. DOE has determined that adoption of PTAC and PTHP standards more stringent than ANSI/ASHRAE/IES Standard 90.1-2013 is not economically justified.
