Effective January 1, 2023, the Department of Energy has mandated new minimum efficiency standards. These changes will impact newly manufactured air conditioners and heat pumps that may affect the system(s) installed in your new home.
NEW TESTING STANDARDS
Today, home heating and cooling systems use a testing procedure, the M Standard, to rate their energy efficiency. The cooling efficiency of air conditioners and heat pumps are measured in Seasonal Energy Efficiency Rating (SEER), and the heating efficiency of heat pumps are measured in Heating Season Performance Factor (HSPF).
Beginning in 2023 the Department of Energy will measure energy efficiency with a new testing procedure known as the M1 Standard. This new testing procedure will produce energy efficiency ratings that use new terms to describe energy efficiency: SEER2, and HPSF2. The M1 Standard produces SEER2 and HSPF2 ratings that have lower numerical values compared to the M standard. For example, a system that is rated 16 SEER using M Standard would achieve approximately 15.2 SEER2 under M1 Standard.
Your replacement will come with a reliable HVAC system from TRANE, whether your system has an M standard or M1 standard system, that adheres to Department of Energy requirements for energy efficiency.
This means starting from January 2023, as Department of Energy converting efficiency ratings to SEER2/EER2 standards, model numbers and efficient ratings are subject to change.
