New Minimum Efficiency Standards The new 2023 system efficiency minimums may differ by product type. 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. All products manufactured prior to January 1, 2023, may be installed on or after January 1, 2023. |

North Region The chart above outlines the regional standards for ducted and ductless split system air conditioners, split system heat pumps, single-packaged air conditioners and single-packaged heat pumps. All products manufactured prior to January 1, 2023, may be installed on or after January 1, 2023. |

| 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. |
