Heat Pumps in Duluth: What Homeowners Should Know
Duluth has roughly 9,130 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 $18,000 — or about $15,000 after the local rebate of up to $3,000.
Swapping electric-resistance heat for a heat pump in Duluth cuts heating costs from about $5,008 to $2,276 a year — a saving of roughly $2,732 annually at the local electricity rate of $0.156/kWh, and an estimated $37,321 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 Minnesota rebates and the income-qualified HEEHRA program (up to $8,000) can still bring the cost down. The local utility is Minnesota Power.
