Heat Pumps in Butte: What Homeowners Should Know

Butte has roughly 8,683 heating degree days a year, a very cold climate that determines how hard a heat pump works each winter. A typical 2,000 sq ft home here needs about a 5-ton system, installed for around $17,000 — or about $16,500 after the local rebate of up to $500.

Swapping electric-resistance heat for a heat pump in Butte cuts heating costs from about $3,175 to $1,443 a year — a saving of roughly $1,732 annually at the local electricity rate of $0.104/kWh, and an estimated $16,673 over 15 years. Savings are even larger if you currently heat with propane or oil. Note: the federal 25C heat-pump tax credit expired at the end of 2025, but Montana rebates and the income-qualified HEEHRA program (up to $8,000) can still bring the cost down. The local utility is NorthWestern Energy.
