Heat Pump vs Furnace: Should You Replace or Repair?
Repair the furnace or switch to a heat pump? Compare repair cost, system age, energy savings, and climate to decide.
Furnace repair runs $150–$650 for most fixes and makes sense when the unit is under 12–15 years old and the repair is below 30–50% of a replacement. Switching to a heat pump ($5,000–$18,000 installed) is the bigger move: it replaces both heating and cooling, runs on electricity, cuts energy bills 30–50% in moderate climates, and qualifies for federal and utility rebates. If your furnace is old, inefficient, or facing a major repair like a cracked heat exchanger, a heat pump often pays back the difference within 5–10 years. For a young furnace with a minor fault, repair is the economical call.
