SEER2 vs. SEER: What’s the Difference?

Beginning in 2023, manufacturers will be required to comply with new testing standards for efficiency ratings to represent field performance more accurately. There will be new metrics and new naming for these updated ratings: SEER2, EER2, HSPF2.

How are these Ratings Calculated?

The Increase of static pressure used during efficiency testing means SEER2 and EER2 ratings will be approximately 5% lower than current SEER and EER ratings. Additionally, HSPF2 ratings will be approximately 15% lower. This does not equate to a loss of performance.

What Does this Mean?

During this transitional period, SEER and SEER2, EER and EER2, and HSPF and HSPF2 ratings will be published for all products. Current AHRI system matches will be updated and relaunched in accordance with these new standards.
