New Standards for Residential HVAC Units in 2023
The new standards require a no less than 14 SEER for residential systems in the northern part of the United States and 15 SEER in the southern part of the United States, where cooling loads are a larger share of home energy use.
- Minimum efficiency standard increasing (over 7%)
- New efficiency testing standards (SEER2, EER2, HSPF2) are more stringent
- 0.5” external static pressure (current testing is up to 0.3” E.S.P.)
- More accurately simulate real world home installations
- As a result, SEER2, EER2, and HSPF2 will all be lower
- SEER2 ratings approximately 5% lower
- SEER2 ratings approximately 4% lower
- >HSPF2 ratings approximately 15% lower (does not result in a loss of performance)
- During the transition, SEER and SEER2, EER and EER2, and HSPF and HSPF2 ratings will be published for all product lines
- All AHRI system matches will be updated to comply with the new standards|
