2023 DOE Regional HVAC Efficiency Standards

New Minimum Efficiency Standards

Every six years, the Department of Energy reviews energy use of certain home appliances and mechanical systems in an ongoing effort to reduce overall energy consumption in the United States. If it is determined that an increase in energy efficiency requirements is justified, higher requirements are put into effect.

On January 1, 2023, the Department of Energy’s new minimum efficiency standards will go into effect. The changes include:

• The minimum efficiencies for all new split air conditioners, heat pumps, packaged units, and ductless will change
• A more rigorous testing standard (known as the ‘M1 Standard’) will produce new efficiency rating metrics

The new 2023 system efficiency minimums may differ by product type and in some cases, system rated capacity.

The following chart outlines your regional standards for ducted and ductless split system air conditioners, split system heat pumps, single-packaged air conditioners and single-packaged heat pumps. Split air conditioners that do not meet the new 2023 M1 Standards will not be allowed to be installed on or after January 1, 2023. Split heat pumps and single-packaged products manufactured prior to January 1, 2023, may be installed on or after January 1, 2023.
