Cost to Install a Heat Pump

The cost to install a heat pump is $4,500 to $12,000, installed. A single-zone ductless mini-split sits near the bottom. A whole-house ducted system, or a cold-climate model with backup heat, sits near the top.

A heat pump both heats and cools, so it can replace a furnace and an AC together. This guide covers the two main types, the electrical work they need, and the rebates that change the real cost.

What It Costs to Install a Heat Pump

A ducted air-source heat pump for a whole house runs $6,000 to $12,000, matched to existing ductwork. A ductless mini-split for one or two rooms runs $4,500 to $8,000. A multi-zone ductless system with three or four heads runs $9,000 to $18,000.

The equipment is the largest share. Labor is $1,500 to $4,000. An electrical circuit or a panel upgrade, backup heat strips, and a pad or wall brackets add the rest.

The table below shows cost by system type. Read the cold-climate section if you live where winter lows drop below about 25 degrees.

One number that surprises people: the install price before rebates is often close to a furnace-plus-AC replacement, because you are replacing both at once. The savings show up in the monthly bill and in the incentives, not the sticker.

Ducted vs. Ductless

A ducted heat pump uses your existing supply and return ducts, so it feels like a normal central system. It is the natural swap for a home that already has a furnace and AC.

A ductless mini-split mounts an air handler on the wall of each room it serves, fed by a small refrigerant line through the wall. It suits additions, homes with no ductwork, and rooms that are always too hot or cold.

Many homes use both: a ducted system for the main house and a mini-split for a converted attic or garage. Our cost to replace a central AC unit guide covers the ducted cooling side.

Air-Source vs. Cold-Climate Models

A standard air-source heat pump works well down to about 25 to 30 degrees, then leans on electric backup heat. In a mild climate that is all you need.

A cold-climate heat pump holds most of its capacity down to 5 degrees or lower. It costs $1,500 to $4,000 more but cuts the backup-heat electricity bill sharply where winters are hard.

Ground-source, or geothermal, heat pumps are the most efficient of all but cost $18,000 to $45,000 because of the ground loop. They are a niche choice for large lots and long ownership.

Where the Money Goes

The outdoor unit and the indoor air handler or heads are 50 to 65 percent of the job. A ducted matched system is $3,000 to $7,000 in equipment; a multi-zone ductless system is more.

Labor is $1,500 to $4,000. Electric backup heat strips are $300 to $900. A dedicated 240-volt circuit is $300 to $800, and a panel upgrade, if the service is full, is $1,300 to $3,000.

A permit and inspection are $100 to $500. See our cost to install a gas furnace guide for the dual-fuel comparison.

Do You Need an Electrical Upgrade?

A heat pump adds a large electric load, especially with backup heat strips. A 200-amp panel with open slots usually handles it. A loaded 100-amp panel often does not.

The contractor runs a load calculation. If the service cannot carry the heat pump plus the strips, you either upgrade the panel or choose a cold-climate model that needs far less backup.

A dual-fuel setup avoids the problem. A gas furnace handles the coldest days instead of electric strips, so the electrical demand stays low.

Rebates and Tax Credits

Heat pumps carry some of the largest home-energy incentives available. Federal tax credits, state programs, and utility rebates can together cut $2,000 to $8,000 off a qualifying install.

The rules change often and depend on the equipment rating and your income. Confirm what applies before you sign, not after.

The Department of Energy heat pump page and your utility are the places to check current offers.

Sizing and Comfort

Sizing matters more with a heat pump than with a furnace. An oversized unit short-cycles, struggles with humidity, and gives up efficiency.

A right-sized variable-speed heat pump runs long, gentle cycles that hold a steady temperature and dry the air well. That steady output is the main comfort difference people notice after switching.

Insist on a Manual J load calculation and, for ducted systems, a duct check. Weak or leaky ducts hurt a heat pump more than they hurt a furnace.

Running Cost vs. a Furnace

In a mild or moderate climate, a heat pump usually costs less to run than a gas furnace, and far less than propane, oil, or electric resistance heat.

In a very cold climate with cheap natural gas, a standard heat pump can cost more to run in the deep of winter because of the backup strips. A cold-climate model or a dual-fuel setup closes that gap.

It also replaces your AC, so compare the combined heating-and-cooling cost, not just the heating line.

Common Mistakes When Switching

The most common error is an undersized cold-climate rating. A unit labeled for your square footage at 47 degrees may deliver far less at 5 degrees, so ask for the rated capacity at your winter design temperature, not just the nominal tonnage.

The second is ignoring the ducts. A furnace can push heat through leaky ducts; a heat pump moves cooler air and needs that airflow. Have the ducts checked and sealed before, not after.

The third is skipping the rebate paperwork until the job is done. Many programs require pre-approval or a specific equipment tier, so confirm eligibility before you sign the contract.

What to Expect on Install Day

A ducted swap onto existing ductwork is a one to two-day job. The crew sets the outdoor unit, swaps the indoor coil or air handler, wires the controls and any backup heat, and commissions the system.

A ductless multi-zone install takes longer, because each wall head needs a mount, a line set through the wall, and a condensate route. Expect two to three days for a three or four-head system.

Commissioning matters more than with a furnace. Ask the crew to record the refrigerant charge, the airflow, and the capacity test, and to leave you those numbers.

How to Keep the Cost Down

First, get three quotes that each include the load calculation, the equipment model numbers, and the rated capacity at your design temperature. Compare like for like.

Second, line up every rebate and credit before the install. Third, keep and seal the existing ductwork rather than replacing it, if the contractor confirms it is sound.

Fourth, choose a cold-climate model only if your winters justify it. Fifth, replace in spring or fall for lower pricing and faster scheduling.

Bottom Line

Budget $6,000 to $12,000 to install a heat pump as a whole-house ducted system, or $4,500 to $8,000 for a single-zone mini-split. Add for a cold-climate model, backup heat, or a panel upgrade, and subtract the rebates, which can be large.

Right-size it with a load calculation, seal the ducts, and stack every incentive. If you also have an aging furnace and AC, a heat pump often replaces both. Compare it against a gas furnace and a straight AC replacement, and keep the ducts clean.
