Consumer Central Air Conditioners and Heat Pumps

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

Central air conditioners and heat pumps include split system central air conditioners and heat pumps, single package central air conditioners and heat pumps, small-duct high-velocity products, and space constrained products.  They are installed as part of an indoor climate control system.  They may or may not use ducts to distribute cooled or dehumidified air to more than one room.   Some ductless air conditioners and heat pumps are configured as split systems and are commonly referred to as mini-splits or multi-splits.  Due to their configuration as split systems, mini- and multi-splits are also defined as central air conditioners and heat pumps rather than room air conditioners. 10 CFR 430.2 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for residential central air conditioners and heat pumps since 1992.

Recent and Ongoing Activities

DOE has published a Federal Register notice amending the test procedures for central air conditioners and heat pumps that will be required for certification of compliance with applicable energy conservation standards starting January 1, 2023, to address a limited number of specific issues, and making minor corrections to the current test procedures that are required for certification of compliance with applicable energy conservation standards prior to January 1, 2023. This rulemaking does not satisfy the 7- year lookback requirement prescribed by EPCA.

  • The effective date of this rule is November 25, 2022.
  • The final rule changes will be mandatory for product testing starting April 24, 2023.
  • The incorporation by reference of a certain publication listed in the rule was approved by the Director of the Federal Register on February 6, 2017.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.

Enforcement of Regional Standards

DOE has issued final guidance pertaining to the certification and compliance of energy conservation standards for central air conditioners and heat pumps, particularly on how these topics relate to regional standards for these products.

DOE has published a Federal Register final rule pertaining to the enforcement of regional standards for central air conditioners 81 FR 45387 (July 14, 2016).  This rule adopts requirements related to the enforcement of regional standards for central air conditioners.

The residential central air conditioners and heat pumps enforcement of regional standards rulemaking docket EERE-2011-BT-CE-0077 contains all notices, public comments, public meeting transcripts, and supporting documents pertaining to this rulemaking.


Current Standard

Residential central air conditioners and central air conditioning heat pumps 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 CFR 430.32(c)(3).


Current Test Procedure

To determine that residential central air conditioners and heat pumps 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 430.23(m).

For methodology to determine low-temperature heat pump performance, follow these instructions.
