How much does heat pump replacement cost?
Heat pump replacement commonly costs $6,000 - $15,000+ installed for a ducted system. High-efficiency cold-climate models, dual-fuel setups, electrical upgrades, duct corrections, or backup heat changes can push projects above that range.
The estimate should separate the outdoor unit, indoor air handler or coil, backup heat source, thermostat/controls, electrical work, permit, warranty, and rebate assumptions.
Common heat pump replacement scenarios
Standard ducted heat pump swap
$6,000 - $11,000How to tellExisting ducted heat pump is being replaced with a similar size and no major support work
The fixReplace outdoor unit and matched indoor equipment, test refrigerant charge and airflow
High-efficiency or cold-climate heat pump
$10,000 - $18,000+How to tellContractor recommends variable-speed or cold-climate equipment for better winter performance
The fixCompare efficiency, low-temperature capacity, rebate eligibility, and backup heat needs
Dual-fuel heat pump and gas furnace
$10,000 - $20,000+How to tellHome keeps gas backup but uses a heat pump for most heating and all cooling
The fixConfirm controls, changeover temperature, gas venting, and matched equipment
Electrical or backup heat changes
$500 - $4,000+ extraHow to tellPanel, breaker, disconnect, heat strips, or wiring cannot support the new setup
The fixInclude electrician scope and permit in the quote
Duct or airflow problems
$500 - $5,000+ extraHow to tellExisting system struggles in some rooms or has high static pressure
The fixCorrect returns, supply ducts, insulation, sealing, or balancing before blaming equipment size
Before approving a heat pump quote
- Ask whether the quoted unit can heat your home at your local winter design temperature without relying too heavily on expensive backup heat.
- Confirm whether the indoor unit, coil, air handler, or furnace is being replaced too.
- Ask for SEER2, HSPF2, low-temperature capacity, warranty, and exact model numbers.
- Check utility, state, federal, and manufacturer rebate rules before signing. Not every heat pump qualifies.
- If switching from gas or oil, ask about comfort expectations, operating cost, panel capacity, and backup heat.

When a heat pump deserves a closer look
- You need both heating and cooling replacement
- You have high electric or fuel bills and old equipment
- Your climate and utility rates make heat-pump operation favorable
- There are rebates that materially change the project cost
- You want to reduce gas or oil usage without giving up backup heat
Repair, replace, or convert?
If the heat pump is newer and needs a small part, repair can be sensible. If it needs a compressor, coil, reversing valve, major refrigerant work, or repeated service calls, replacement is worth pricing. If you are converting from another heat source, treat it as a design project, not a simple equipment swap.

Related questions
Is a heat pump cheaper than a furnace and AC?
It can be, especially when it replaces both heating and cooling equipment and qualifies for incentives. The answer depends on climate, utility rates, backup heat, equipment tier, and duct/electrical work.
Do heat pumps work in cold weather?
Modern cold-climate heat pumps can work well in many colder regions, but capacity drops as outdoor temperature falls. The quote should explain backup heat and expected winter performance.
How long does a heat pump last?
Many heat pumps last 10-15 years, sometimes longer with good installation, airflow, maintenance, and reasonable climate load.
Can I replace only the outdoor heat pump unit?
Sometimes, but the indoor coil or air handler must be compatible. A mismatched setup can reduce performance and complicate warranty coverage.
