Seer2 Geary Pacific Supply Air conditioning systems. some practical examples of changes effective january 1, 2023, would have the seasonal energy efficiency rating (seer) for residential split air conditioning systems < 45kbtu h for the northern region moving from 13.0 seer to 14.0 seer or 13.4 seer2 (an updated version of the seer. The national heat pump minimum efficiency will increase from 14.0 to 15.0 seer. starting in 2023, all products must be rated using the doe appendix m1 testing procedure, denoted as seer2, eer2 and hspf2. ratings tested under m1 have been generated using external static pressures that are up to 5x higher than doe’s pre 2023 appendix m test.
Seer2 Changes The new doe testing requirements will also result in changes to the airflow set point on indoor blowers, including fan coils and furnaces. *15.0 seer if less than 45k btu, or 14.5 seer if at or above 45k btu, eer requirements also apply in the southwest region: 12.2 eer < 45k btu or 11.7 eer ≥ 45k btu, if seer > 16 then eer minimum is 10.2. 2023 energy efficiency standards. effective january 1, 2023, energy efficiency metrics for residential air conditioners and heat pumps are expressed in terms of seasonal energy efficiency ratio (seer2), energy efficiency ratio (eer2), and heating seasonal performance factor (hspf2). old metrics. All 2023 compliant products will include a new energyguide label with the seer2, eer2 and hspf2 ratings. heating & air equipment affected by seer2. air conditioner condensing units. beginning january 1, 2023 during the rollout of seer2 regulatory changes, heating and cooling equipment must become compliant to us regional minimum energy. The new standards effective in 2023 require a seasonal energy efficiency ratio (seer)—a measure of a system’s cooling performance—of 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.
