Heat Pump & Smart Thermostat

No changes to timing and eligibility requirements:

HVAC System Type Existing 2022 Efficiency Requirements NEW 2023 Efficiency Requirements
Geothermal Heat Pump (closed loop) ≥ 17.1 EER & ≥ 3.6 COP No Changes
Smart Thermostat* ENERGY STAR® Certified Smart Thermostat No Changes

*Limit 3 per household.

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.

COP = Coefficient of Performance: A ratio that measures the efficiency of a heat pump. The higher the number, the more efficient the heat pump.
