Montana Energy Rebates 2026
Montana homeowners in 2026 can access federal HEAR and HOMES rebates administered by the Montana Department of Environmental Quality (DEQ), plus utility programs from NorthWestern Energy (the state's primary investor-owned utility). Montana has a severely cold continental climate, making energy efficiency and heat pump upgrades especially high-value. The 25C and 25D federal tax credits expired December 31, 2025. Montana's abundant natural gas and relatively low electric rates from hydropower create unique energy economics.
HOMES Rebate Program in Montana
| Income Level | Max Rebate | Cost Coverage |
|---|---|---|
| Low income (≤80% AMI) | Up to $8,000 | 80% of project cost |
| Moderate income (80-150% AMI) | Up to $4,000 | 50% of project cost |
| Above 150% AMI | Not eligible | N/A |
HOMES rebates are administered by Montana DEQ. Provides up to $4,000 for 20–35% whole-home energy savings and up to $8,000 for 35%+ savings. Income-qualified households (≤80% AMI) receive doubled amounts. Montana's cold climate and older rural housing stock create strong HOMES savings potential.

Frequently Asked Questions
What energy rebates are available in Montana in 2026?
Montana homeowners in 2026 can access: (1) Federal HEAR rebates for cold-climate heat pumps (up to $8,000), heat pump water heaters ($1,750), insulation ($1,600), and electrical panels ($4,000) for income-qualified households (≤150% AMI); (2) HOMES whole-home performance rebates up to $8,000; (3) NorthWestern Energy utility programs; (4) Free weatherization for income-qualified households. The 25C and 25D federal tax credits expired December 31, 2025.
Are federal tax credits still available in Montana?
No. The One Big Beautiful Bill Act (OBBBA, P.L. 119-21, signed July 4, 2025) terminated the Section 25C and 25D federal energy tax credits for installations after December 31, 2025. For 2026 installations, HEAR and HOMES are the primary federal incentive paths.
Can heat pumps work in Montana's harsh winters?
Yes — with the right cold-climate heat pump. Montana winters can reach -30°F to -40°F in some locations. Cold-climate heat pumps with ENERGY STAR cold-climate certification are rated to -13°F, handling most Montana winters. For extreme cold events, electric backup heat (built into most heat pump systems) activates automatically. Many Montana installations use a dual-fuel approach: cold-climate heat pump + existing propane/gas backup for the coldest nights. Given propane's high cost, replacing propane heating with a heat pump + HEAR rebate ($8,000 for qualifying households) often has excellent ROI.
Who administers HEAR and HOMES in Montana?
Montana's Department of Environmental Quality (DEQ) administers both programs. Contact Montana DEQ or visit their website for participating contractors and current program status. Montana's Human Resource Councils and Community Action Agencies provide weatherization services for income-qualified households.
Is propane-to-heat-pump conversion especially valuable in Montana?
Yes. Montana has significant rural propane-heated homes, and propane is expensive (often $3–5/gallon). Switching from propane heat to a cold-climate heat pump — even with Montana's relatively low electric rates (~11¢/kWh) — typically reduces annual heating costs by 40–60%. The HEAR rebate (up to $8,000 for qualifying households) makes the upfront investment much more manageable, often producing payback in 5–8 years.
