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.
