Finding energy rebates and incentives
Incentives can cut the cost of insulation, heat pumps, water heaters and smart thermostats. Here's what changed and where to look now.
What changed
The federal tax credits for energy-efficient home improvements (Section 25C) and residential clean energy such as rooftop solar (Section 25D) ended for property placed in service after December 31, 2025, under legislation passed in 2025. If someone promises you one of these federal credits for work done in 2026, ask them to show you the current rule in writing.
Where to look now
Your electric and gas utilities
The most common source of rebates: heat pumps, heat pump water heaters, insulation and air sealing, smart thermostats, appliance recycling and free or low-cost home energy assessments. Search your utility's website for "rebates".
DSIRE
A long-running database of state, utility and local incentives, searchable by ZIP code.
ENERGY STAR rebate finder
Search by ZIP code for rebates on specific ENERGY STAR certified products.
Your state energy office
Some states run home energy rebate programs funded by federal grants or state budgets. Availability, eligibility and timing vary widely.
Weatherization Assistance Program
Free weatherization for income-eligible households through state and local agencies.
Before you buy anything
- Confirm the rebate is open and still has funding.
- Check product and installer requirements; some rebates need a participating contractor or pre-approval.
- Keep receipts, model numbers, AHRI certificates for HVAC equipment and installer invoices.
