How much does a heat pump cost to install?
A heat pump runs $4,500 to $20,000 installed, and that spread is the whole story. The size of the unit explains part of it. The rest is your ductwork, your electrical panel, whether you need a cold-climate model, and which contractor you ask. This guide breaks the installed price down by size and type, shows where the money actually goes, and explains why the same house gets quotes that differ by thousands.
Short answer
A typical 3-ton ducted heat pump runs $9,000 to $14,000 installed.
That is the mid-tier, average-complexity number most homes land near. A single-zone mini-split can be half that. A cold-climate system with a panel upgrade and new ductwork can be double. The price you get depends far more on the condition of your home than on the brand on the box.
Installed, by type
- • Single-zone mini-split: $3,000 to $6,000
- • Multi-zone mini-split: $8,000 to $14,500
- • Ducted central, 3-ton: $9,000 to $14,000
- • Cold-climate ducted: $12,000 to $20,000
- • Geothermal: $20,000 to $35,000
How much does a heat pump cost installed?
The price has two parts, and online listings only show one. The equipment by itself is roughly half the total: a 3-ton outdoor unit and matching indoor coil or air handler runs $4,000 to $8,500 at the distributor. Labor, refrigerant, electrical, the thermostat, permits, and hauling away the old system make up the other half. The figure you see advertised for "the unit" is never what shows up on the quote.
For a typical ducted air-source heat pump replacing an existing system on usable ductwork, most homes land between $9,000 and $14,000 all-in at mid-tier efficiency. The full national spread runs from about $4,500 for a single-zone mini-split up to $20,000 for a premium cold-climate system. Where you fall inside that range comes down to size, equipment tier, and the condition of the house, which the rest of this guide walks through.
Heat pump installation cost by size: 2, 3, 4, and 5 ton
Tonnage is sized to your home's heating and cooling load, not square footage alone, but a rough guide is one ton per 500 to 600 square feet in a moderate climate. Run the heat pump sizing calculator for an accurate load before you price anything. These are typical installed ranges for a ducted mid-tier system:
- 2-ton (about 1,000 to 1,200 sqft): $7,000 to $11,500
- 3-ton (about 1,500 to 1,800 sqft): $9,000 to $14,000
- 4-ton (about 2,000 to 2,400 sqft): $10,500 to $16,000
- 5-ton (about 2,500 to 3,000 sqft): $12,000 to $18,000
Notice the jumps between sizes are small. Going from a 3-ton to a 4-ton adds a few thousand dollars at most, because the labor, the line set, and the electrical work are nearly the same regardless of capacity. The thing that moves the price is not whether you buy a 3 or a 4, it is everything around the unit. An oversized unit is the more common and more expensive mistake, since it short-cycles and never dehumidifies properly.
It helps to see where the money goes on a typical 3-ton job. The outdoor unit runs roughly $2,500 to $5,000, the indoor coil or air handler another $1,500 to $3,500, and refrigerant, electrical, the thermostat, and the drain line add $700 to $2,700. Labor lands around $2,500 to $5,500, with permits and the load calculation a few hundred more on top. Add it up and the equipment is a little over half the bill and the install is the rest. That split is why two contractors quoting the same outdoor unit can still land thousands apart, and it is why a higher-priced quote is sometimes the better deal if it includes work the cheaper one skipped.
Ducted central heat pump vs ductless mini-split cost
A ducted central heat pump uses your existing ductwork and one outdoor unit, which keeps the per-zone cost low when the ducts are already there. A ductless mini-split mounts an indoor head in each room or zone and runs refrigerant lines instead of ducts. Single-zone mini-splits start around $3,000 to $6,000 installed. Each added head costs nearly as much as the first, so a 3-zone or 4-zone system lands at $8,000 to $14,500 with no volume discount.
The rule of thumb is simple. If you already have good ductwork, a ducted heat pump is usually the cheaper way to condition the whole house. If you have no ducts, an addition, a converted garage, or a few rooms that never get comfortable, a mini-split avoids the $3,500 to $7,000 cost of installing ductwork from scratch. The heat pump vs mini-split comparison walks through which one fits your layout.
There is a third type that sits at the top of the price ladder. A geothermal heat pump pulls heat from the ground through buried loops instead of from the outdoor air, which makes it the most efficient option and by far the most expensive to install, commonly $20,000 to $35,000 because of the digging and the ground loop. It only pencils out on a long timeline, in a home you plan to keep for decades, and the geothermal cost calculator runs that math. For most homes the decision is between a ducted air-source unit and a mini-split, not geothermal.
Why two quotes for the same house can differ by thousands
This is the question most cost guides skip. You can get three quotes for the same heat pump on the same house and see a $4,000 to $6,000 spread. It is almost never one contractor gouging you. It is that each one scoped the job differently. The big drivers:
- Ductwork: one contractor reuses your ducts, another prices in $2,000 to $7,000 of repair or replacement after measuring static pressure and finding them leaky or undersized.
- Electrical: a heat pump may need a panel that has room for it. Adding a circuit is cheap. A full 200-amp service upgrade is $1,500 to $7,000 depending on your area.
- Equipment tier: a builder-grade single-speed unit and a variable-speed cold-climate model can both be "a heat pump" on a quote and differ by $2,000 to $4,000.
- Sizing method: a contractor who runs a real load calculation may spec a smaller, cheaper unit than the one who matched whatever was already there.
- Overhead: a larger company with a sales team and financing carries more overhead than a two-truck shop, and it shows in the bottom line.
The fix is to make every quote describe the same scope. Ask each contractor to itemize the equipment model, the ductwork plan, and the electrical work separately so you are comparing the same job, not three different jobs. The HVAC replacement cost calculator gives you a line-item baseline to hold the quotes against.
Why heat pumps cost more now: the refrigerant change explained
New heat pump prices stepped up recently and the reason is the refrigerant inside them. Under the federal AIM Act, manufacturers stopped building new residential systems with the old R-410A refrigerant and switched to lower-warming replacements, mainly R-454B and R-32. The changeover pushed wholesale refrigerant and equipment prices up across the board, and a new system today commonly runs 10 to 20 percent more than the same unit cost before the transition.
There is no waiting it out. R-410A equipment is being sold off as remaining inventory, and buying it to dodge the price bump leaves you owning a system on a refrigerant that is being phased down, which makes future repairs more expensive as that refrigerant gets scarce. The practical move is to buy a current R-454B or R-32 system and treat the higher price as the new baseline. The refrigerant recharge cost calculator shows how the same change is moving repair pricing on existing systems.
The hidden costs: panel upgrades, line sets, permits, and backup heat
The base quote covers the unit and a standard swap. These add-ons are where a clean-looking price grows, and any of them can be legitimate depending on your home:
- Electrical panel upgrade: $1,000 to $3,500 for a sub-panel or circuit add, up to $7,000 for a full 200-amp service upgrade.
- New line set: $200 to $1,200. Required if the old lines are damaged, undersized, or were used with R-22.
- Backup electric heat strips: $300 to $1,000 installed. Common in colder zones so the system has heat on the coldest days.
- Permits and inspection: $100 to $500, more in strict-code cities. A contractor who skips the permit is a red flag, not a discount.
- Old equipment removal: $100 to $1,000, including recovering the old refrigerant, which is required by law.
- Ductwork modifications: $300 to $1,200 for minor repairs, $2,000 to $7,000 for a full replacement.
Get these itemized before you sign. A quote that buries "electrical as needed" without a number is the one that surprises you mid-install.
The add-ons also explain why install times vary so much. A straight changeout that reuses your ductwork and electrical is usually a one-day job for a two-person crew. The moment a quote includes a panel upgrade, new ductwork, or running a circuit, it stretches to two or three days, and that extra labor is a real part of the higher number, not padding. When you compare quotes, a longer install is often the sign of a more thorough scope, so ask each contractor how many days they expect and what is driving it.
Cost to replace a heat pump, and can you replace just the outdoor unit?
Replacing a worn-out heat pump costs about the same as a new install, $9,000 to $14,000 for a typical ducted system, since the labor and electrical are nearly identical. The money-saving question homeowners ask is whether they can replace only the dead outdoor unit and keep the indoor coil. Sometimes, but the conditions are strict.
You can usually swap just the outdoor unit if it is the same brand, the same tonnage, and the same refrigerant as the indoor coil. The refrigerant is the catch. An old R-22 or R-410A coil will not match a new R-454B outdoor unit, and mixing them voids the warranty and tanks the efficiency you paid for. Once your existing coil is a generation behind on refrigerant, the outdoor-only swap stops being an option and you are looking at a full system. A contractor who offers an outdoor-only replacement should be able to show you the indoor coil matches on brand, size, and refrigerant before you agree to it.
How much extra does a cold-climate heat pump cost?
A cold-climate or hyper-heat heat pump holds its heating output at low outdoor temperatures where a standard model fades. That capability runs $1,000 to $3,000 more than a comparable standard heat pump, and up to $4,000 to $5,000 more when it also moves you to a full variable-speed system. In a warm climate that premium is wasted. In a cold one it is the difference between a heat pump that carries the winter and one that leans on expensive backup heat through every cold snap. The cold-climate heat pump guide covers which climate zones actually need it.
Heat pump rebates that lower your cost
The federal 25C tax credit that paid 30 percent up to $2,000 toward a qualifying heat pump ended for systems installed after December 31, 2025. If your unit was running by that date, you can still claim it on your return. For an install today, the federal credit no longer applies, so do not let a contractor quote it as a live discount.
State and utility rebates are where the real savings still live, and in many states they are larger than the federal credit ever was. Income-qualified households may also reach the state-administered rebate programs, where funding is available, for several thousand dollars more. Programs change often and some run out of money mid-year, so check current status before you count on it. The rebate finder pulls every program that applies to your zip code and income tier, and the payback period calculator shows when the upgrade pays for itself once the rebates and lower running cost stack up.
