Heat pump replacement cost
Replacing a heat pump typically costs $5,000–$15,000 installed for a ducted system — less after state and utility rebates. Here is what to budget.
Heat pump replacement prices (2026)
| System | Installed (before incentives) |
|---|---|
| Ducted air-source | $5,000–$12,000 |
| Ductless mini-split (per zone) | $3,500–$5,000 |
| Geothermal | $18,000–$45,000 |
Replacing is usually cheaper than a first-time install because the ductwork, electrical and pad are often reusable. Price your exact size with the cost calculator.
What drives replacement cost
- Size (tons) — bigger homes need more capacity.
- Type — ducted vs ductless vs geothermal.
- Reusable infrastructure — good existing ducts and a suitable electrical panel keep it cheaper.
- Efficiency tier — higher HSPF2/SEER2 costs more but saves more.

Frequently asked questions
How much does it cost to replace a heat pump?
Most ducted replacements run $5,000–$12,000 installed before incentives; ductless mini-splits $3,500–$5,000 per zone; geothermal $18,000–$45,000.
Is replacing cheaper than a new install?
Usually a bit, because existing ductwork, electrical and the pad can often be reused.
Does a replacement qualify for rebates?
Many state and utility rebates apply to replacements as well as first installs if you fit a qualifying ENERGY STAR unit. (The federal 25C/25D credit expired at the end of 2025.)
When is it time for a heat pump replacement?
Consider a heat pump replacement when the unit is 10–15+ years old, repairs are getting frequent or exceed about half the cost of a new system, your energy bills are climbing, or it still uses phased-out R-22 refrigerant.
