Heat pump replacement cost
Replacing an existing heat pump with a similar ducted system costs about $5,000 to $11,000, since the ducts, wiring and pad are already in place. Upgrading to a high-efficiency or cold-climate model can push the price to $15,000 or more.
Quick answer
$5,000 – $11,000like-for-like ducted replacement
Most heat pump replacements cost $5,000 to $11,000. Small systems start near $4,000; premium variable-speed or cold-climate units with a new air handler reach about $18,000.

What's included
- New outdoor heat pump and matching indoor air handler or coil
- Refrigerant, line set flush or replacement, and pad
- Electrical disconnect and connection
- Thermostat compatible with heat pump staging
- Removal of old equipment and refrigerant recovery
Ask whether the air handler is being replaced. Matching it is usually required for rated efficiency and the full warranty.
Repair or replace?
| Repair | Typical cost |
|---|---|
| Service call / diagnosis | $75 – $200 |
| Capacitor | $100 – $250 |
| Circuit board | $150 – $700 |
| Blower motor | $300 – $900 |
| Refrigerant leak repair | $200 – $1,500 |
| Compressor | $1,300 – $2,500 |
| Air handler | $1,500 – $3,400 |
Heat pumps last about 10 to 20 years. If yours is over 10 years old and needs a compressor or a major refrigerant leak repair, replacing it usually makes more sense. See Should you repair or replace your HVAC system?.
Upgrade options
Variable-speed (inverter) heat pumps cost more but heat better in cold weather, run quieter and control humidity. In very cold areas, a dual-fuel setup that keeps your gas furnace as backup can be the cheapest way to go. Compare Heat pump vs. furnace: which costs less?.
How to get a fair quote
- Get at least three written quotes that list the brand, model number, size (tons or BTU) and efficiency rating.
- Ask whether the price includes permits, removal of the old unit, refrigerant, a new thermostat and any duct or electrical work.
- Ask for a load calculation (Manual J) instead of matching the old unit's size by default.
- Compare labor warranties (1 to 10 years) as well as the manufacturer's parts warranty, and register the equipment.
- Schedule non-urgent work in spring or fall, when contractors are less busy and more willing to discount.
Frequently asked questions
How much does it cost to replace a heat pump?
About $5,000 to $11,000 for a typical ducted heat pump replacement, depending on size and efficiency.
How long does a heat pump last?
About 10 to 20 years. Heat pumps run year-round, so they tend to wear out sooner than air conditioners.
Should I replace my heat pump and air handler together?
Usually yes, so the indoor and outdoor units are matched for efficiency, refrigerant type and warranty.
