Castle Rock Heat Pump Rebates 2026
Here is the honest picture for Castle Rock in 2026. The rebates you can count on today are Black Hills Energy's cold-climate heat-pump rebate ($2,500) and Colorado's $1,000 state heat-pump tax credit -- about $3,500 combined. The $8,000 federal HEAR rebate is currently closed in this area, so we do not put it in the headline. The calculator below shows your exact eligibility.
Your utilities: CORE Electric and Black Hills Energy
Castle Rock's electricity comes from CORE Electric Cooperative, while its natural gas is served by Black Hills Energy. Black Hills runs the heat-pump rebate that applies here: $1,500 for an air-source heat pump and $2,500 for a cold-climate model. Because Castle Rock sits at about 6,200 feet, the cold-climate tier is usually the right one. Utility budgets are finite, so the calculator confirms the current amount for your address.
Where the federal HEAR rebate stands here
HEAR is run by region in Colorado. Castle Rock is on the Front Range (Region 1), which stopped accepting new applications on April 28, 2026, while the mountain and Western Slope counties (Region 2) remain open. So we do not count the $8,000 HEAR heat-pump rebate in your Castle Rock total today, and no reopening has been announced.
Colorado state heat-pump tax credit: $1,000
Colorado offers a $1,000 state heat-pump income-tax credit for the 2026 tax year, available to every Colorado taxpayer regardless of income, and it stacks with the Black Hills rebate. It sunsets at the end of 2026, so a 2026 installation is the window to claim it.

Frequently Asked Questions
How much can I get for a heat pump in Castle Rock?
It depends on your equipment and income, so use the calculator for an exact number. The dependable pieces in Castle Rock today are Black Hills Energy's cold-climate heat-pump rebate ($2,500; $1,500 for a standard air-source unit) and Colorado's $1,000 state tax credit -- about $3,500. The $8,000 federal HEAR rebate is not currently claimable here because HEAR closed to new Front Range applications on April 28, 2026.
Is the Colorado HEAR rebate available in Castle Rock right now?
Not currently. Colorado runs HEAR by region, and Castle Rock (Douglas County) is on the Front Range (Region 1), which stopped accepting new applications on April 28, 2026, with no reopening announced. The mountain and Western Slope counties (Region 2) remain open, so the $8,000 HEAR heat-pump rebate is not part of what a Castle Rock household can claim today.
What utility serves Castle Rock?
Castle Rock's electricity comes from CORE Electric Cooperative, and its natural gas from Black Hills Energy. Black Hills runs the heat-pump rebate that applies here: $1,500 for an air-source heat pump and $2,500 for a cold-climate model. Utility programs change through the year and have limited funding, so the calculator confirms the current amount for your address.
Can I combine the state credit with the utility rebate in Castle Rock?
Yes. Colorado's $1,000 state heat-pump tax credit stacks with the Black Hills rebate on the same project. Note that the federal 25C tax credit expired December 31, 2025, and the federal HEAR rebate is regionally gated and currently closed on the Front Range. Work with a contractor approved for the Black Hills program.
