Heat Pumps in Helena: What Homeowners Should Know

Helena has roughly 8,684 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 Helena cuts heating costs from about $3,786 to $1,721 a year — a saving of roughly $2,065 annually at the local electricity rate of $0.124/kWh, and an estimated $23,057 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.
