SEER2 Regulations and More beginning 2023
The US Department of Energy implemented a new minimum energy efficiency standard for heat pumps and air conditioners applying to all equipment manufactured after January 1, 2023. The changes present new challenges in what can already feel like an overwhelming process when comparing and selecting a new heating and cooling system. Mountaineer Heating & Cooling continues to work with manufacturers to monitor the changes, provide the most up-to-date information, and help simplify the process for you as home and business owners.
The minimum operating efficiency also increased. The new minimum is 14.3 SEER2 / 7.5 HSPF2 (the equivalent of 15 SEER / 8.8 HSPF using the previous rating metrics) *.
Equipment manufactured prior to January 1st, 2023 may still be installed, providing it meets the previous standard from 2015 (Minimum rating of 14 SEER / 8.2 HSPF)
This has happened before and will likely happen again. After much discussion and back and forth through various administrations during the 1970’s and 1980’s, The National Appliance Energy Conservation Act was adopted in 1987 and implemented in 1992 declaring 10 SEER / 6.8 HSPF as the minimum efficiency standard. The minimum efficiency was raised in 2000 (implemented in 2006) to a minimum of 13 SEER. Similarly, the minimum efficiency was raised again in 2011 (implemented in 2015), but for the first time was based on geographical location with our region increasing to 14 SEER / 8.2 HSPF. The new M1 Standard increases efficiency once again and this time comes with a new metric for system rating. The new standard regulates minimums of 14.3 SEER2 / 7.5 HSPF2 or the equivalent of what was 15 SEER / 8.8 HSPF using the previous metrics.
