Great Falls, Montana quick facts
Frequently asked questions — Great Falls
Does my electrical panel in Great Falls have room for a heat pump?
Most 200A panels in Great Falls have enough headroom for a heat pump under NEC 220.82 Optional Method load calculations — which account for load diversity rather than worst-case simultaneous demand. A 100A panel is more likely to require an upgrade, especially if you also plan to add an EV charger or electric range. Our free 3-minute audit runs the same NEC 220.82 Optional Method your electrician would use — no site visit required for a preliminary assessment.
What heat pump rebates are available in Great Falls, Montana?
Great Falls homeowners can access Montana state and utility rebates. HEEHRA federal rebates have not yet launched in Montana. The top state/utility program is NorthWestern Energy Residential Efficiency Rebates (NorthWestern Energy), offering up to $500 for qualifying heat pumps. IRA 25C expired December 31, 2025 and is not available for 2026 installations.
How much does a heat pump cost in Great Falls?
In Great Falls, a whole-home air-source heat pump typically costs $6,000–$17,000 installed (2026 estimates). That range includes equipment and labor; ductwork modifications, electrical work, or panel upgrades add cost. IECC Zone 6B means a cold-climate rated unit is recommended — these cost 10–20% more but run efficiently to -13°F. Combined Montana rebates can offset part of the total — verify program availability before purchasing.
Is the IRA 25C tax credit available for Great Falls homeowners?
No. The IRA Section 25C non-refundable tax credit expired December 31, 2025. It is not available for heat pump systems installed in 2026. If your system was installed before December 31, 2025, you can still claim it on your 2025 federal tax return (IRS Form 5695). For 2026, the remaining federal incentive is HEEHRA (where Montana has an active, funded program). Geothermal heat pumps may still qualify for Section 25D (30%, no cap, through 2032).
What IECC climate zone is Great Falls in?
Great Falls falls in IECC 2021 Zone 6B — Cold-Dry. Cold climate — a cold-climate ASHP rated to -13°F or better is required for reliable heating all winter. For exact sizing, a Manual J load calculation is required — but as a rough starting point, allow 20–30 BTU/h per square foot for older Great Falls homes.
