How Much Does Heat Pump Replacement Cost?
Heat pump replacement typically costs about $7,800 at the Standard level when you replace a 3-ton heat pump and indoor coil in a 2,000 to 2,500 square foot home, and about $5,200 to $12,400 across the Budget to Premium range. Replacing only the outdoor unit costs less, and a full system with a new air handler costs more.
This calculator uses the following planning figures for a 3-ton system in a 2,000 to 2,500 square foot home, standard 14 to 15 SEER2 efficiency, a new line set, an existing electrical connection that is still fine, a basement or utility-room indoor unit, easy outdoor access, removal of the old system, a permit allowance and an average labor market:
| Replacement | Budget | Standard | Premium |
|---|---|---|---|
| Outdoor heat pump only | $4,235 | $6,395 | $10,325 |
| Heat pump + new indoor coil | $5,195 | $7,830 | $12,390 |
| Heat pump in place of an AC (dual fuel) | $5,610 | $8,485 | $13,435 |
| Heat pump + electric air handler | $6,490 | $9,770 | $15,470 |
| Package heat pump (ground pad) | $5,770 | $8,760 | $13,875 |
Change any input and the numbers update, because the calculator prices equipment, line set, electrical connection, labor, removal and permit separately.

What Affects Heat Pump Replacement Costs?
What you are replacing
A swap of only the outdoor unit keeps the indoor coil, which makes it the lowest-cost option. A heat pump with a new indoor coil is the most common replacement, because the two parts are designed to work as a matched pair. Replacing an AC with a heat pump while you keep a gas furnace gives a dual-fuel system, and the calculator adds the controls that let the furnace take over in deep cold. A full system adds a new electric air handler, and a package unit replaces everything in one outdoor cabinet.
Home size and system size
The calculator maps your home size to about 1.5 to 5 tons. For a heat pump and coil, the Standard estimate runs from about $5,670 for a home up to 1,000 square feet, to about $6,390 for a home of 1,000 to 1,500 square feet, about $9,265 for a home of 2,500 to 3,500 square feet and about $10,705 for a home over 3,500 square feet. A new unit is sized from a load calculation and not just copied from the old one.
Efficiency level
Higher-efficiency heat pumps cost more up front and use less electricity. A high-efficiency, two-stage unit raises the Standard heat pump and coil estimate from about $7,830 to about $9,340. A premium variable-speed inverter unit raises it to about $11,605. Variable-speed units run longer at lower speeds, which improves comfort and efficiency.
Refrigerant line set
The line set connects the indoor and outdoor units. A new line set is the default, and it is recommended for most replacements. Reusing and flushing the existing lines lowers the Standard estimate to about $7,365, but only when the lines are the right size and clean. Newer refrigerants may require new or flushed lines.
Electrical connection
The default assumes the existing disconnect and whip are fine. A new disconnect and whip raises the Standard estimate to about $8,045, and a new circuit and breaker raises it to about $8,675. A new circuit is needed when the new unit is larger or when the old wiring is damaged.
Install location and access
An indoor coil or air handler in a basement or utility room is the easy case. A closet or crawl space takes more time, and an attic is the hardest. An attic install raises the Standard estimate from about $7,830 to about $8,180. A tight outdoor location, such as a narrow gate or stairs, raises it to about $8,005. A package unit on the roof needs a crane, which raises the Standard package estimate from about $8,760 to about $9,885.
Outdoor pad and stand
The old pad may be cracked, sunken or the wrong size for the new unit. Choosing a new composite pad raises the Standard estimate to about $8,100. In snow country, a raised stand or wall bracket keeps the unit above drifts and raises it to about $8,225.
Thermostat and optional upgrades
A smart thermostat raises the Standard estimate to about $8,205. A hard-start kit, a surge protector, a condensate pump, a media filter cabinet, a UV light or air purifier and a line-set cover each add parts and labor. Upgrades appear only when they apply to the replacement type you chose.
Removal and disposal
The old system must be removed, and its refrigerant has to be recovered by a certified technician. The calculator includes removal, refrigerant recovery and disposal by default. If you uncheck it, the Standard estimate for a heat pump and coil falls from about $7,830 to about $7,345.
Permits
Many cities require a permit and an inspection for a heat pump replacement. The calculator includes a permit allowance of about $200 at the Standard level by default. If you remove it, the Standard estimate falls to about $7,630. The allowance is a planning placeholder, not the municipal fee.
Urgency
Urgent and after-hours calls carry a premium. The calculator adds 15% to labor for work within about 48 hours and 40% for emergencies. An emergency replacement raises the Standard heat pump and coil estimate from about $7,830 to about $8,400.
Budget vs Standard vs Premium Heat Pump Replacement
The three project levels reflect real differences, not a simple multiplier:
Budget
A basic equipment line, a leaner labor rate and fewer labor hours.
Standard
Mid-grade equipment, quality line-set and electrical parts and a licensed installer at typical rates.
Premium
Premium equipment, higher-grade parts, more thorough commissioning and premium service rates.
Use Standard as your main planning number, and the Budget-to-Premium range to see how much your choices can swing the result.
Repair vs Replace
Replacement can make sense when the heat pump is more than about 10 to 15 years old, when it uses the older R-22 refrigerant, when the compressor has failed or when repairs keep adding up. A newer unit is also usually more efficient. If the unit is newer and the problem is small, a repair may be the better choice. Use the AC repair calculator to compare the numbers for the cooling side before you decide.
Regional Pricing Differences
HVAC labor rates and permit practices vary across the country. Rather than guess from your ZIP code, the calculator lets you choose a labor market, from lower-cost areas to the highest-cost metro areas, and applies it to labor, removal and crane rental. A low-cost market lowers the Standard heat pump and coil estimate to about $7,610, and the highest-cost market raises it to about $8,560. Equipment and materials are not adjusted.
DIY vs Hiring a Licensed HVAC Contractor
Replacing a heat pump is not a DIY project. It involves recovering and handling refrigerant, which requires certification, evacuating and charging the lines, wiring the unit and checking airflow. Most areas require a licensed contractor and a permit. A poor install wastes energy and can shorten the life of the compressor.
Questions to Ask HVAC Contractors
- Will you replace the coil along with the outdoor unit, and is the system a matched pair?
- Will you perform a load calculation to confirm the size?
- Which brand and model numbers are in the quote, and what are the SEER2 and HSPF2 ratings?
- Is the line set new, or flushed and reused, and why?
- Does the quote include removal, refrigerant recovery, the permit and the pad?
- Which rebates or tax credits does this model qualify for, and who files the paperwork?
How to Avoid Unexpected Heat Pump Replacement Costs
- Replace the coil with the outdoor unit when the old coil does not match the new unit.
- Check the electrical connection and the pad before the install day.
- Ask for a written scope that lists the equipment, line set, electrical work, removal and permit.
- Check rebates before you sign. Programs and eligible models change.
- Do not wait for a cold snap. Emergency winter calls cost more.

Request QuotesQuick Answers About Heat Pump Replacement Costs
How much does heat pump replacement cost?
Heat pump replacement commonly costs about $7,800 at the Standard level for a 3-ton heat pump and indoor coil in a 2,000 to 2,500 square foot home, and about $5,200 to $12,400 across the Budget to Premium range.
What is the difference between replacing the outdoor unit and the whole heat pump system?
The outdoor unit is the part outside the home. Replacing only the outdoor unit costs less, but a new unit matched to an old indoor coil can lose efficiency. A full system replaces the outdoor unit, the coil and sometimes the air handler.
Can you replace an AC with a heat pump?
Yes. A heat pump uses the same outdoor and indoor equipment layout as an AC, so it can replace one. With a gas furnace kept as backup, the result is called a dual-fuel system.
How much does a new line set add to a heat pump replacement?
In this calculator, reusing and flushing the old line set lowers the Standard heat pump and coil estimate from about $7,830 to about $7,365, so a new line set adds roughly $465.
What is the biggest cost driver in heat pump replacement?
The equipment size and efficiency level are the biggest drivers, followed by whether you replace the coil and air handler, and the electrical and access conditions.
Heat Pump Replacement Cost FAQs
How much does heat pump replacement cost?
In this calculator, a Standard estimate for replacing a 3-ton heat pump and indoor coil in a 2,000 to 2,500 square foot home is about $7,830, with a Budget to Premium range of roughly $5,195 to $12,390. Replacing only the outdoor unit is about $6,395, and a full system with a new air handler is about $9,770.
How much does it cost to replace just the outdoor heat pump unit?
Replacing only the outdoor unit runs about $6,395 at the Standard level for a 3-ton model, with a range of about $4,235 to $10,325. Many installers advise replacing the indoor coil as well, because a new outdoor unit matched to an old coil can lose efficiency and may affect the warranty.
How much does it cost to replace an AC with a heat pump?
Replacing an AC with a heat pump while keeping your gas furnace gives a dual-fuel system. The Standard estimate is about $8,485, which includes the dual-fuel controls and an outdoor sensor that let the furnace take over in deep cold. A matched indoor coil is included.
How much does a bigger or more efficient heat pump add to the cost?
Size and efficiency both raise the price. For a heat pump and coil, the Standard estimate runs from about $5,670 for a home up to 1,000 square feet to about $10,705 for a home over 3,500 square feet. A high-efficiency unit raises the 3-ton estimate to about $9,340, and a premium variable-speed unit raises it to about $11,605.
Can I reuse my existing refrigerant line set?
Sometimes. If the lines are the right size and clean, they can be flushed and reused, which lowers the Standard estimate from about $7,830 to about $7,365. Many installers recommend a new line set, especially when the refrigerant type changes, and your installer confirms what is safe to reuse.
Does the heat pump replacement estimate include removal of the old unit?
Yes, by default. The estimate includes removing the old system, recovering the refrigerant and disposing of the equipment. Unchecking it lowers the Standard estimate from about $7,830 to about $7,345. Refrigerant must be recovered by a certified technician and cannot be vented.
Do I need a permit to replace a heat pump?
Many cities require a permit and an inspection for heat pump replacement. The calculator includes an allowance of about $200 at the Standard level, and removing it lowers the estimate to about $7,630. Real fees are set by your city or county, so ask your contractor or building department.
How long does a heat pump last, and when should I replace it?
Heat pumps often last about 10 to 15 years because they run in both seasons. Replacement can make sense when the unit is old, the compressor has failed, it uses the older R-22 refrigerant or repairs keep adding up. A newer unit is also usually more efficient.
