2023 HVAC industry is making big changes towards sustainability starting January 1st, 2023.

  • New test procedures from the Department of Energy, also known as M1, will be used with new equipment.
  • Seer (Seasonal Energy Efficiency Ratio) measures the output compared to the electrical usage it consumes. The higher the SEER, the more efficient
  • The new M1 equipment will convert to SEER2, EER will become EER2 and HSPF will be HSPF2.  Any three-phase equipment with less than 65,000 BTU will continue to use the old SEER.
