Heat Pumps in Cambridge: What Homeowners Should Know

Cambridge has roughly 6,593 heating degree days a year, a cold climate that determines how hard a heat pump works each winter. A typical 2,000 sq ft home here needs about a 4-ton system, installed for around $17,500 — or about $7,500 after the local rebate of up to $10,000.

Swapping electric-resistance heat for a heat pump in Cambridge cuts heating costs from about $6,583 to $2,633 a year — a saving of roughly $3,950 annually at the local electricity rate of $0.284/kWh, and an estimated $67,723 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 Massachusetts rebates and the income-qualified HEEHRA program (up to $8,000) can still bring the cost down.
