All models of S9X2 and S9V2 furnaces have been updated, and system ratings for those furnaces have been released in AHRI. A cross-functional team reviewed all ratings affected, including those not originally released.
Most ratings were unchanged from those with the old furnace model numbers. In the process of re-rating, however, some ratings were rounded off (i.e., a 16.25 SEER rating may have been rounded to 16 SEER, or a 12.75 EER may have been rounded off to 12.5).
For those few that did change, due to DOE rating requirements that changed in the interim, we have made every effort to ensure there are reasonable substitutions available.
