As defined in the Code of Federal Regulations (CFR), “Room Air Conditioner” means a consumer product, other than a “packaged terminal air conditioner,” which is powered by a single phase electric current and which is an encased assembly designed as a unit for mounting in a window or through the wall for the purpose of providing delivery of conditioned air to an enclosed space. It includes a prime source of refrigeration and may include a means for ventilating and heating. 10 CFR 430.2. Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for Residential Room Air Conditioners since 1990.

Recent and Ongoing Activities

DOE has published a Federal Register final rule; correction notice pertaining to test procedure for room air conditioners. On March 29, 2021 DOE published a final rule adopting test procedures for room air conditioners (hereafter the “March 2021 final rule”). This document corrects errors and omissions in the Federal test procedure for room air conditioners as amended by the March 2021 final rule, including an incorrect mathematical notation and missing detail regarding the full compressor speed setpoint in the testing instructions. Neither the errors and omissions, nor the corrections in this document, affect the substance of the rulemaking or any conclusions reached in support of the final rule.

  • The correction is effective May 7, 2021. 

DOE has issued a pre-publication Federal Register notice Final Rule pertaining to test procedures for Room Air Conditioners. On June 11, 2020, DOE issued a notice of proposed rulemaking (NOPR) to amend the test procedure for room air conditioners. That proposed rulemaking serves as the basis for the final rule. Specifically, this final rule adopts the following updates to the test procedure for room ACs at appendix F: incorporate by reference current versions of applicable industry standards; establish test provisions to measure energy use of variable-speed room ACs during a representative average use cycle; update definitions to define key terms and support provisions for testing variable-speed room ACs; and incorporate specifications and minor corrections to improve the test procedure repeatability, reproducibility, and overall readability. This final rule does not modify the test procedures for single-speed room ACs and does not affect the measured energy use for these models. The provisions established to measure energy use of variable-speed room ACs will improve the representativeness of the measured energy use of these models.

DOE has published Federal Register notice extending the public comment period for the preliminary analysis it has conducted for purposes of evaluating energy conservation standards for room air conditioners (ACs). DOE published the notice of webinar and availability of preliminary technical support document in the Federal Register on June 17, 2020, establishing a 60-day public comment period ending August 17, 2020. On August 3, 2020, DOE received a comment requesting extension of the comment period by 14 days. DOE is extending the public comment period for submitting comments and data on the notice of webinar and availability of preliminary technical support document by 14 days, to September 8, 2020.

DOE has published a Federal Register notice announcing a webinar to discuss and receive comments on the preliminary analysis it has conducted for purposes of evaluating energy conservation standards for room air conditioners (ACs). The webinar will cover the analytical framework, models, and tools that DOE is using to evaluate potential standards for this product; the results of preliminary analyses performed by DOE for this product; the potential energy conservation standard levels derived from these analyses that DOE could consider for this product should it determine that proposed amendments are necessary; and any other issues relevant to the evaluation of energy conservation standards for room ACs.

DOE has published a Federal Register notice of proposed rule pertaining to test procedures for room air conditioners (room ACs). The notices proposes to amend the test procedure for room ACs to address updates to the industry standards that are incorporated by reference, provide for the testing of variable-speed room ACs to better reflect their relative efficiency gains at lower outdoor temperatures as compared to single-speed room ACs, and to provide specifications and minor corrections that would improve repeatability, reproducibility, and overall readability of the test procedure. Because there are no testing modifications proposed for single-speed room ACs, DOE expects that the proposed changes will not affect the measured energy use for these models. For variable-speed room ACs, the proposed changes will improve the representativeness of the measured energy use of these models. As part of this proposal, DOE is announcing a public webinar to collect comments and data on its proposal.

Current Standard

Residential Room Air Conditioners 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 430.32(b).


Current Test Procedure

To determine that Residential Room Air Conditioners 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 430, Subpart B, Appendix F.
