Heat pump cost — the short answer
Installed US prices for 2026, before any state or utility rebate. Local quotes routinely land 15–30% either side of these.
| System | Typical installed cost | Who it's for |
|---|---|---|
Mini split, 1 zone | $1,500 – $4,500 | One room, an addition, a garage or office |
Mini split, 2 zones | $4,000 – $9,000 | A floor, or two rooms that need separate control |
Mini split, 4–5 zones | $8,000 – $18,000 | Most of a house, ductless |
Air-source, whole house | $8,000 – $15,000 | Standard ducted replacement |
Air-source, large / complex | up to $25,000 | Big homes, new ductwork, difficult installs |
Geothermal (ground-source) | $12,000 – $30,000+ | Long-horizon owners with land to dig |
The number most people are looking for is $8,000 to $15,000 — a whole-house air-source heat pump, installed, in 2026. If you only need to condition one room, the number is $1,500 to $4,500 for a single ductless mini split zone, and about $3,000 is where most of those quotes land.
Those two figures are far apart because “heat pump” describes two quite different purchases, and most cost guides blur them into one average that matches neither. This page separates them, then explains the part that changed this year: the federal tax credit that used to take up to $2,000 off the total no longer exists.
The one thing that changed in 2026: the 25C credit is gone
If you read this page a year ago, or you are reading another cost guide today, you will see a promise of 30% back, up to $2,000, on a qualifying heat pump. That was the Section 25C Energy Efficient Home Improvement Credit, and it is no longer available.
The IRS states the credit is allowed for qualifying property placed in service on or after 1 January 2023 and before 31 December 2025. The early end date came from the One Big Beautiful Bill Act (P.L. 119-21), signed 4 July 2025. The practical version:
- A system placed in service in 2025 can still be claimed, on your 2025 return, using Form 5695. That deadline has passed for new work but not for paperwork.
- A system installed in 2026 gets nothing from 25C.
This matters more than a footnote, because it moves the actual number you write on a cheque by up to $2,000 — and because a large share of the cost guides currently ranking for these searches still quote the credit with no expiry note. If a contractor’s quote shows the credit as a deduction, that quote is wrong.
What is still live: state programmes and utility rebates are separate from the federal credit and many continue to run, some of them generous. They are administered locally, so the only reliable check is your own state energy office and your own utility. ENERGY STAR maintains a rebate finder that is a reasonable starting point.
Mini split cost, by number of zones
| System | Typical installed cost | Labour share |
|---|---|---|
| 1 zone | $1,500 – $4,500 (≈$3,000 typical) | $300 – $2,000 |
| 2 zones | $4,000 – $9,000 | $700 – $3,000 |
| 4–5 zones | $8,000 – $18,000 | $700 – $3,000+ |
| DIY-style kit (equipment only) | $800 – $2,000 | — |
Zones, not BTUs, are what move a ductless quote. Each additional indoor head adds equipment, a line-set run, a condensate path and labour — which is why the second zone roughly doubles a single-zone job while the fifth adds proportionally less.
The DIY kit line deserves a caution. Pre-charged units exist and are legal to buy, but the moment a line has to be cut, evacuated or recharged, federal law requires an EPA Section 608 certified technician. A self-install also voids most manufacturer warranties. The full breakdown, including how to read an itemised quote, is in our mini split installation cost guide.
Whole-house heat pump cost
| Type | Typical installed cost |
|---|---|
| Air-source, standard ducted replacement | $8,000 – $15,000 |
| Air-source, large home or new ductwork | up to $25,000 |
| Ductless, single zone | $1,500 – $4,500 |
| Geothermal (ground-source) | $12,000 – $30,000+ |
The regional spread on the same equipment is genuinely enormous — the identical air-source system can be an $8,000 job in a low-cost market and a $30,000 one in a high-cost city with a difficult install. That is not a reason to distrust the range; it is the reason to get two or three local quotes rather than budgeting from a national average.
What drives the price
Size and zones. More BTUs and more indoor heads cost more. But bigger is not better: an oversized system short-cycles, dehumidifies poorly and wears faster. Right-sizing is a calculation (a Manual J load calculation), not a guess, and a contractor who sizes by square footage alone is a contractor to be sceptical of.
Install complexity. This is the line item homeowners underestimate. An electrical panel that needs upgrading, a long line-set run, difficult mounting, or replacing ductwork can add thousands with no change to the equipment.
Efficiency tier (SEER2 / HSPF2). Higher ratings cost more upfront and cut the running cost. The break-even depends on your climate and your electricity price — in a mild climate with cheap power, the premium tier can take longer to pay back than the equipment lasts.
Local labour rates. Often the single largest regional variable.
Brand. Real but smaller than expected. Premium names (Mitsubishi, Daikin) cost more; the comparison is in our Mitsubishi vs Daikin breakdown. Installation quality moves long-term running cost more than the badge on the box does.
The cost that isn’t in the quote: running it, and fixing it
A purchase price is only part of the arithmetic, and the two numbers below are the ones that decide whether the system was a good buy five years in.
Running cost. A heat pump moves heat instead of generating it, which is why the Department of Energy describes it as delivering considerably more energy than it consumes. The saving is real but it is relative — the gain is largest when replacing electric resistance heating, and smallest when replacing a modern, efficient gas furnace in a region with cheap gas and expensive electricity.
Repair cost. Budget for it before you need it. The average heat pump repair in the US is about $400, with most landing between $150 and $650 — but the range runs from a $100 capacitor to a $2,500 compressor. Full part-by-part pricing, and the calculation for deciding whether to repair or replace an ageing system, is in heat pump repair cost.
Maintenance. Mostly free and mostly filters. A restricted filter raises energy use, and it is the root cause behind a surprising share of “the system is broken” service calls — see cleaning the filter and the maintenance guide.
Is it worth it in 2026?
The equipment case is unchanged: one system does the work of a furnace and an air conditioner, and it does it by moving heat rather than burning fuel. The financing case is weaker than it was in 2025, because the $2,000 federal credit is gone and nothing federal replaced it.
So the honest answer depends on what you are replacing:
- Replacing electric resistance heat (baseboards, furnace with electric strips): the strongest case, and it survives the loss of the credit comfortably.
- Adding conditioning to a room that has none — an addition, a converted garage, an attic office: a single-zone mini split at around $3,000 is usually the cheapest route to a comfortable room, credit or no credit.
- Replacing a dead AC and an old furnace together: strong, because you were buying two systems anyway.
- Replacing a working, modern gas furnace: the weakest case financially in 2026. There may be good non-financial reasons to do it, but the payback maths no longer flatters it the way it did last year.
Before you sign
- Get two or three quotes, and get each one itemised — equipment, labour, electrical, permits, separately.
- Ask how the system was sized. The answer should reference a load calculation, not square footage.
- Confirm the licence and the EPA 608 certification.
- Check state and utility rebates yourself rather than taking the contractor’s word — and treat any quote showing the expired federal 25C credit as a red flag about the rest of the numbers.
- Ask what the warranty requires. Most require professional install and documented maintenance to stay valid.
