Sign up for e-mail updates on regulations for this and other products

As defined in the Code of Federal Regulations (CFR), “packaged terminal air conditioner” means a wall sleeve and a separate un-encased combination of heating and cooling assemblies specified by the builder and intended for mounting through the wall, and that is industrial equipment. It includes a prime source of refrigeration, separable outdoor louvers, forced ventilation, and heating availability by builder's choice of hot water, steam, or electricity. “Packaged terminal heat pump” means a packaged terminal air conditioner that utilizes reverse cycle refrigeration as its prime heat source, that has a supplementary heat source available, with the choice of hot water, steam, or electric resistant heat, and that is industrial equipment. 10 CFR 431.92 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for PTACs and PTHPs since 1994.

Recent and Ongoing Activities

DOE has published a Federal Register notice undertaking the preliminary stages of a rulemaking to consider amendments to the test procedures for Packaged Terminal Air Conditioners (PTACs) and Packaged Terminal Heat Pumps (PTHPs). Through this request for information (RFI), DOE seeks data and information regarding issues pertinent to whether amended test procedures would more accurately or fully comply with the requirement that the test procedure produces results that measure energy use during a representative average use cycle for the equipment without being unduly burdensome to conduct, or reduce testing burden.  DOE welcomes written comments from the public on any subject within the scope of this document (including topics not raised in this RFI), as well as the submission of data and other relevant information.

DOE has published a Federal Register notice initiating an early assessment review to determine whether any new or amended standards would satisfy the relevant requirements of EPCA for a new or amended energy conservation standard for Packaged Terminal Air Conditioners (PTACs) and Packaged Terminal Heat Pumps (PTHPs). Specifically, through this request for information (RFI), DOE seeks data and information that could enable the agency to determine whether DOE should propose a “no new standard” determination because a more stringent standard: Would not result in a significant savings of energy; is not technologically feasible; is not economically justified; or any combination of foregoing. DOE welcomes written comments from the public on any subject within the scope of this document (including those topics not specifically raised in this RFI), as well as the submission of data and other relevant concerning this early assessment review.

  • Frequently Asked Questions on the Energy Conservation Standards for Consumer Products; Early Assessment Review: Packaged Terminal Air Conditioners and Packaged Terminal Heat Pumps

DOE has published a Federal Register notice undertaking an early assessment review to determine whether to proceed with a rulemaking to amend DOE’s test procedures for packaged terminal air conditioners (PTACs) and packaged terminal heat pumps (PTHPs) to adopt the most recent procedures referenced in the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1, “Energy Standard for Buildings Except Low-Rise Residential Buildings,” which are consistent with DOE’s current test procedures, unless there exists clear and convincing evidence supporting the adoption of alternate procedures. DOE welcomes written comments from the public on any subject within the scope of this document (including topics not raised in this RFI), as well as the submission of data and other relevant information concerning this early assessment review.

Current Standard

PTACs and PTHPs manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 431.97(c).


Current Test Procedure

To determine that PTACs and PTHPs that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 431.96.
