New Regulatory Requirements

THE CHANGE

NEW REGULATORY REQUIREMENTS

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 These changes may present new complexities, but American Standard® Heating & Air Conditioning is committed to leading our industry in compliance and is prepared to support our partners every step of the way

Why the Change?

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.

New Testing Standards

The new testing procedure (the M1 Standard) increases the external static pressure at which ratings are calculated by up to 5 times the static pressure used in today’s test procedure, effectively reducing the rated efficiency of equipment for both heating and cooling. The heating load line has also been redefined. This new load line will favor variable speed systems and will therefore have a larger negative impact on 1-stage and 2-stage HSPF ratings. The ratings created by the new M1 Standard will be published using new ratings nomenclatures: SEER2, EER2, and HSPF2. 

New Minimum Efficiency Standards

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.
