Tier 1 & 2 Split Systems and Single Package

Equipment installed on or after 1/1/23 must meet the New Efficiency Requirements:

HVAC System Type Existing 2022 Efficiency Requirements NEW 2023 Efficiency Requirements
Central Air Conditioner Tier 1 – Split System ≥ 16 SEER and ≥ 12.5 EER ≥ 15.2 SEER2 and ≥ 12.0 EER2
Central Air Conditioner Tier 1 – Single Package ≥ 16 SEER and ≥ 12.5 EER ≥ 15.2 SEER2 and ≥ 11.5 EER2
Central Air Conditioner Tier 2 – Split System ≥ 18 SEER and ≥ 12.5 EER ≥ 16.9 SEER2 and ≥ 12.4 EER2
Central Air Conditioner Tier 2 – Single Package ≥ 18 SEER and ≥ 12.5 EER ≥ 16.9 SEER2 and ≥ 11.5 EER2

SEER = Seasonal Energy Efficiency Rating: A rating that denotes the efficiency of air conditioning equipment. The higher the SEER, the more efficient the unit and the lower the operating cost.

EER = Energy Efficiency Rating: The ratio of an air conditioning unit’s cooling capacity in British thermal units (Btus) per hour to the total electrical input in watts.
