Enhanced Heat Pump Rebates

Increased incentives for high-efficiency heat pumps
Back to Enhanced Residential Program

Heating & Cooling accounts for more than 50% of the average home’s energy use. You can significantly reduce your home's energy consumption, carbon footprint and energy usage by upgrading to energy efficient heat pumps. Combined with weatherization upgrades, your new heat pump will provide comfort, convenience, and energy savings.

Heat pumps can efficiently heat your home in the winter and double as a cooling system in the summer to keep your home comfortable all year long. Based on your income, you may qualify for an even higher rebate on heat pumps.

Air source heat pumps are also available for up to no‑cost. We will even help with the entire process from start to finish. Learn more here.

 

Eligible customers may qualify for a Seasonal Heat Pump Rate, which offers lower electric rates from November through April to help make heat pump operation more affordable. Seasonal Heat Pump Rates can help lower your heating costs while future rate options designed around when you use your energy are developed to provide greater control over your energy bill.

 

Rebate applications for equipment purchased in 2025 must be submitted by February 28th, 2026.
