System Requirements
For contractors in the north region, compliance is determined by each system's manufacturing date. This allows ample time to sell 13.0 SEER inventory.
To meet SEER2 requirements in this region, residential central air systems below 45,000 Btu must have a SEER2 rating of 13.4 (14.0 SEER). Residential central air systems 45,000 Btu and above must have a SEER2 rating of 13.4 (14.0 SEER) as well. In addition, heat pumps in any region must meet 14.3 SEER2 (15.0 SEER) and 7.5 HSPF2 (8.8 HSPF) requirements. For more information on SEER2 rules and regulations, visit our SEER2 page.
