Packaged Terminal Air Conditioners and Heat Pumps



Department of Energy

The Department of Energy (DOE) has regulated the energy efficiency level of packaged terminal air conditioners and heat pumps since 1994. Packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs) are through-the-wall space conditioning units commonly used in lodging, townhouse office complexes, and extended care facilities.

Current Efficiency Standards
Standard Level

Standard size PTAC or PTHP refers to equipment with wall sleeve dimensions having an external wall opening greater than or equal to 16 inches high or greater than or equal to 42 inches wide, and a cross-sectional area greater than or equal to 670 square inches.

Non-standard size refers to PTAC or PTHP equipment with existing wall sleeve dimensions having an external wall opening of less than 16 inches high or less than 42 inches wide, and a cross-sectional area less than 670 square inches.

Standard size packaged terminal air conditioners or packaged terminal heat pumps manufactured on or after September 30, 2012, and distributed in commerce, as defined by 10 CFR 431.92, must meet the energy conservation standards specified in the Code of Federal Regulations 10 CFR 431.97(c). The standards apply to non-standard sized packaged terminal air conditioners and heat pumps manufactured on or after September 30, 2010.
