Montana Heat Pump Rebates
Stackable incentives available to Montana homeowners installing a qualifying heat pump in 2026.
Rebate data is re-verified against primary sources every two months.
What's available in Montana
Montana has no statewide heat pump rebate yet — the state's IRA-funded Home Energy Rebates Program (HEEHRA + HOMES) at the Department of Environmental Quality has not launched, so the income-qualified federal point-of-sale rebates for heat pumps and heat pump water heaters are not available to Montana homeowners. The strongest active incentive is NorthWestern Energy's up-to-$3,000 instant heat pump water heater incentive (pre-approval required, delivered via enrolled participating contractors, funds limited, and stackable with the City of Bozeman's $500 municipal rebate). Missoula County's $1,435 county HPWH rebate closed in October 2025 with all funds allocated; the county now directs residents to NorthWestern Energy or, for co-op members, Missoula Electric Cooperative's $1,400-$1,800 HPWH rebate. Rural electric cooperatives including Flathead Electric and Missoula Electric pay $920 for ductless heat pumps in electric-heated homes (more for income-qualified Flathead members) and also list air-source and ground-source heat pump rebates. Montana-Dakota Utilities currently does not offer a heat pump rebate. Utility and co-op programs are the primary 2026 incentive layer until state HEEHRA launches.

HEEHRA rebate: Point-of-sale rebate up to $8,000 for households at or below 80% of area median income. Funded by the IRA, administered by each state. Montana is finalizing program rules.
How heat pump rebates work in Montana
Montana has no statewide heat pump rebate yet — the state's IRA-funded Home Energy Rebates Program (HEEHRA + HOMES) remains paused at the Department of Environmental Quality awaiting updated DOE guidance, so the income-qualified federal point-of-sale rebates for heat pumps and heat pump water heaters are not yet available to Montana homeowners. The strongest active incentive is NorthWestern Energy's up-to-$3,000 heat pump water heater rebate (delivered via participating plumbing contractors and stackable with the City of Bozeman's $500 municipal rebate; Missoula County's former $1,435 rebate closed in October 2025 and the county now points residents to NorthWestern Energy or Missoula Electric Cooperative's $1,400-$1,800 HPWH rebate). Rural electric cooperatives including Flathead Electric, Missoula Electric, and Yellowstone Valley provide additional ductless, air-source, and ground-source heat pump rebates in the $800-$1,000 range for their members. Montana-Dakota Utilities currently does not offer a heat pump rebate. Utility programs are the primary 2026 incentive layer until state HEEHRA launches.
Montana rebate programs
NorthWestern Energy Heat Pump Water Heater Rebate
$3,000Instant incentive of up to $3,000 for replacing an existing electric water heater with a Tier 3 or Tier 4 heat pump water heater on the Advanced Water Heating Specification qualified products list. Must be installed by an enrolled, trained participating contractor, and each project needs pre-approval before installation; funds are limited and the program is advertised as limited-time with no published end date. Available to NorthWestern Energy residential electric water-heating customers in Montana.
City of Bozeman Heat Pump Water Heater Rebate
$500$500 toward a heat pump water heater for City of Bozeman residents. Note that Bozeman's own page still advertises the rebate as stackable with the federal §25C credit — §25C was repealed effective December 31, 2025, so that pairing is no longer available for 2026 installs.
Missoula County Electric Heat Pump Water Heater Rebate
$1,435CLOSED. Missoula County's own page states the heat pump hot water heater rebate program closed as of October 2025 with all funds allocated, and now directs residents to NorthWestern Energy or Missoula Electric Cooperative instead. Retained for history.
Missoula Electric Cooperative Heat Pump Water Heater Rebate
$1,800$1,400 to $1,800 for a qualified heat pump water heater (on the Bonneville Power Administration qualified product list) that replaces an existing electric storage water heater in a Missoula Electric Cooperative member home. Installed per manufacturer specifications; members submit the co-op's HPWH rebate form with receipts. This is the program Missoula County now points residents to after its own county rebate closed.
Missoula Electric Cooperative Ductless Heat Pump Rebate
$920$920 for a ductless mini-split heat pump installed by a licensed HVAC contractor in a Missoula Electric Cooperative member home that currently heats with electricity. Not available for new construction or gas-heated homes; one rebate per home regardless of the number of heads installed. Members submit purchase and installation receipts to the co-op. MEC also lists separate air-source and ground-source heat pump rebates whose amounts we have not yet confirmed.
Flathead Electric Cooperative Ductless Heat Pump Rebate
$920$920 for a ductless heat pump in a single-family Flathead Electric member home whose primary heat is permanently installed electric resistance (baseboard, cadet heaters, or an electric forced-air furnace). Homes with oil, propane, gas, wood, or pellet furnaces, homes with an existing ducted air-source heat pump, and new construction do not qualify. Use an installer from the co-op's qualified installer list; higher rebate amounts are available for income-qualified members. Flathead also lists air-source and ground-source heat pump rebates whose amounts we have not yet confirmed.

A worked example: HPWH swap in Bozeman
Lauren owns a 1,400 sq ft home in Bozeman served by NorthWestern Energy for electric service and the City of Bozeman for water. Her 16-year-old electric resistance tank water heater is failing. She picks a 65-gallon ENERGY STAR HPWH (UEF 3.45) at $2,800 installed by a NorthWestern-participating plumbing contractor. Because the install replaces an existing electric water heater with a qualifying HPWH, she qualifies for the NorthWestern Energy HPWH rebate at $3,000 — fully covering the project cost. (NorthWestern's rebate caps at $3,000 or actual cost, whichever is lower.) She also qualifies for the City of Bozeman's $500 municipal HPWH rebate, which stacks freely with the NorthWestern rebate. Bonus: $75 for completing the post-install satisfaction survey. Combined stack: $3,000 + $500 + $75 = $3,575 against $2,800 installed. Net effective: roughly $0 out-of-pocket (the NorthWestern rebate caps at actual cost, so she doesn't get refunded above $2,800). The municipal rebate ($500) is paid as a separate Bozeman check. The federal §25C credit for HPWHs is gone for 2026 installs.
Choosing a contractor in Montana
Montana licenses contractors through the Montana Department of Labor and Industry. For HVAC work, look for the Construction Contractor Registration plus EPA Section 608 certification for refrigerant handling. NorthWestern Energy's HPWH rebate requires a participating plumbing contractor; the contractor processes the rebate. Bozeman's municipal rebate is filed by the homeowner separately through bozeman.net. Missoula County's former $1,435 HPWH rebate closed in October 2025 with all funds allocated. Missoula Electric Cooperative members can instead apply directly to the co-op for its $1,400-$1,800 HPWH rebate using the rebate form at missoulaelectric.com.
Common pitfalls for Montana homeowners
- Missing the NorthWestern HPWH rebate program window. NorthWestern Energy's up-to-$3,000 HPWH incentive is advertised as limited-time with limited funds, and every project must be pre-approved before installation. Installs done without pre-approval, or after funds are exhausted, will not be paid, leaving only municipal or co-op rebates. Verify program status before signing a contract for late-2026 installs.
- Counting on Montana HEEHRA for 2026. Montana's IRA-funded Home Energy Rebates Program at the DEQ remains paused awaiting updated DOE guidance. As of April 2026 there's no firm launch date. Income-qualified Montana homeowners cannot rely on the federal point-of-sale rebates for 2026 installs. Monitor deq.mt.gov for status updates.

How to claim each rebate
- Get pre-approved (where required). Some utility programs require approval before install. Check program details before signing a contract.
- Use a participating contractor. Many programs require a licensed installer from an approved contractor list — especially HEEHRA, which routes through CEC-approved contractors who process the rebate at point of sale.
- Save documentation. AHRI certificate, model numbers, and itemized invoice are required for most utility rebates.
- Submit utility rebate within 60–90 days of install. Some programs are first-come first-served and close mid-year — funding can run out before the calendar year does.
If you can't afford a replacement in Montana
Rebates lower the price, but they still assume you can pay the rest. If your heating system is unsafe or has failed and a new one is out of reach, these programs repair or replace equipment at low or no cost for income-qualified households. Heat Pump Pricing Index is an independent information site — we don't fund, discount, or install equipment — so these are the doors to knock on first:
- Weatherization Assistance Program (WAP). Free energy and health-and-safety repairs — an unsafe furnace is exactly the kind of problem it fixes — for households at or near 200% of the poverty line. Apply through your local community action agency: how to apply (energy.gov).
- LIHEAP. Heating-bill help plus, in most states, a crisis component for broken or dangerous heating equipment. Same local agency; Montana LIHEAP contacts.
- USDA Section 504 Home Repair. For homeowners outside cities: 1% loans up to $40,000, and grants up to $10,000 for homeowners 62 and older to remove health and safety hazards. Program page and state offices (rd.usda.gov).
- Your utility and 211. Most electric and gas utilities run an income-qualified assistance fund — call the number on your bill and ask. Dialing 211 reaches a local specialist who knows which agencies in Montana currently have funds.
Safety first: if a technician has told you a heat exchanger is cracked, stop using the furnace and make sure you have a working carbon monoxide detector before anything else.
