You're considering a heat pump and the first thing you need is a realistic budget, not a lowball number that balloons once the quotes come in. Heat pump installation is a significant investment, and the price swings a lot based on the type of system, your home, and where you live.
This guide gives installed-cost estimates by system type and size, covers the factors that push a quote higher, and lays out the 2026 tax credits and rebates, which changed recently. The figures come from NREL's REMDB and are modeled estimates, not quotes, so get several itemized bids for your home; install quality matters more than the brand on the unit.
A ducted air-source heat pump typically costs about $7,450 to $19,250 installed for a 3-ton, 15-SEER (about 14.2 SEER2) system, about $13,350 at the mid estimate, and adding a new electrical circuit adds about $1,400. A single-zone mini split runs about $4,500 to $10,500 (12,000 BTU, 20 SEER), while a ground-source (geothermal) system is much more and NREL's database does not price it.
Your actual cost depends on system type, size, efficiency, your home's electrical and ductwork situation, and your region (California and the Northeast run higher). Get at least three itemized quotes.
NREL derived its heat pump costs largely from California and Massachusetts incentive-program data, adjusted with location multipliers, so they run high relative to some markets.
Cost by system type
The type of heat pump is the biggest single cost factor:
| System type | Installed cost (REMDB; 3-ton unless noted) |
|---|---|
| Ducted air-source, 15 SEER (about 14.2 SEER2) | about $7,450 / $13,350 / $19,250 |
| Ducted air-source, 16 SEER (about 15.2 SEER2) | about $8,000 / $14,250 / $20,500 |
| Single-zone mini split (12,000 BTU, 20 SEER) | about $4,500 / $7,500 / $10,500 |
| Multi-zone mini split (2–4 ton, 18 SEER) | about $7,000–$29,550 |
| Ground-source / geothermal | Not priced by REMDB |
Ducted air-source is the most common, replacing your furnace and AC while using existing ductwork. Higher-efficiency variable-speed units cost more but run quieter and cheaper. Mini splits avoid ductwork and add zoning; cost scales with the number of indoor heads.
Geothermal has by far the highest upfront cost (the ground loop is the expensive part) but the lowest operating cost and longest lifespan, it makes the most sense in new construction or where long-term efficiency justifies the investment. For the ductless option in depth, see our mini split cost guide.
Cost by size
Heat pumps are sized in tons (1 ton = 12,000 BTU), and cost scales with capacity. Installed low, mid and high estimates for a 15-SEER (about 14.2 SEER2) ducted system; REMDB prices 2 through 5 tons, and the "typical home" square-foot ranges are a rough starting point, not a Manual J load calculation:
| Size | Typical home (rough guide) | Installed cost (REMDB: low / mid / high) |
|---|---|---|
| 2 ton (24,000 BTU) | 1,000–1,400 sq ft | about $6,500 / $11,750 / $17,000 |
| 3 ton (36,000 BTU) | 1,800–2,200 sq ft | about $7,450 / $13,350 / $19,250 |
| 4 ton (48,000 BTU) | 2,700–3,200 sq ft | about $8,400 / $14,950 / $21,500 |
| 5 ton (60,000 BTU) | 3,200–4,000 sq ft | about $9,400 / $16,550 / $23,700 |
Important: don't size by square footage alone. Proper sizing comes from a Manual J load calculation (per ACCA) that accounts for your insulation, windows, climate, and layout, an oversized heat pump costs more and runs worse. Use our heat pump size calculator for an estimate, and insist your contractor does a real load calculation.
What the install covers
The REMDB figures above are total installed costs that already bundle the labor and include removing and hauling away the old equipment, so a single number covers all of these steps:
- Removing the old equipment, including recovering its refrigerant.
- Setting the outdoor unit on a pad with vibration isolation.
- Installing the indoor air handler or coil and running the refrigerant line set.
- Making the electrical connection: disconnect, whip and wiring.
- Mounting the thermostat and wiring it in.
- Commissioning the system: charging it, testing it and verifying performance.
- Pulling permits and passing inspection.
Adding a new electrical circuit for the heat pump adds about $1,400 (NREL). The commissioning step matters more than it looks: a heat pump that isn't properly charged and verified at install underperforms for its whole life, so a contractor who does thorough commissioning is worth paying for.
What pushes the cost up
Several common factors can push a quote well above the base price, ask about these up front so your bid reflects reality:
- Electrical panel upgrade. Homes with a 100-amp panel often need a 200-amp upgrade to handle the heat pump's circuit. Replacing a panel runs about $1,000 to $3,100 (NREL REMDB, rough; see our panel upgrade guide). This is one of the most common surprise costs.
- New or modified ductwork. If you lack ducts or the existing ones are in poor shape, new or reworked ductwork is a significant separate cost that REMDB does not price.
- Difficult access. Second-story, tight crawlspace, or attic placements add labor time and cost.
- Long refrigerant runs through finished walls, and cold-climate-rated equipment (built for very low temperatures), both add to the price.
2026 tax credits and rebates (what changed)
This is where the rules shifted recently, so the accurate current picture is this:
The federal Section 25C tax credit expired for installs placed in service after December 31, 2025.
The 25C credit had covered 30% of project cost up to $2,000 for qualifying high-efficiency heat pumps, but it was terminated under the OBBBA (PL 119-21, signed July 4, 2025). It does not offset 2026 installations. The Section 25D credit for geothermal also expired for installs after December 31, 2025.
What's still active in 2026:
- IRA HEAR rebates (income-qualified): up to $8,000 point-of-sale for heat pumps, income-tiered, state-administered.
- IRA HOMES rebates: open to all incomes, performance-based on energy savings, state-administered.
- State and utility rebates: many offer substantial incentives, some quite large. Check the DSIRE database (dsireusa.org) or your state energy office for what's currently funded.
Because the state programs roll out on their own timelines and funding levels, confirm what your state offers, and which equipment qualifies, with your installer before signing. See our heat pump tax credits 2026 guide for details.
How to get a better price
A few practical steps genuinely lower your cost:
- Get at least three itemized quotes, and compare them apples-to-apples (same efficiency tier, same included work). Quotes vary widely because scope and equipment differ, not just price.
- Time it for the shoulder season (spring or fall). Contractors are less slammed than during the first heat wave or cold snap, and you have more negotiating room.
- Stack every incentive you qualify for (state, utility, IRA rebates).
- Prioritize the contractor over the brand. Install quality affects performance and lifespan more than which major brand you choose, a well-installed mid-tier system outperforms a premium unit installed poorly. Look for proper licensing, EPA 608 certification, and a willingness to do a Manual J load calculation. Find qualified contractors through ACCA.
Frequently asked questions
Is it cheaper to install a heat pump or a furnace and AC? A gas furnace (80,000 BTU/hr, 80% AFUE) runs about $3,400 installed and a 3-ton, 14-SEER air conditioner about $5,150, so about $8,550 together at the mid estimate, versus about $13,350 for a 3-ton ducted heat pump at the mid estimate; NREL's heat pump figures lean on California and Massachusetts data, so the heat pump usually costs more upfront. The federal 25C credit that used to help close that gap expired for installs after December 31, 2025, though state and utility rebates plus IRA HEAR/HOMES often still narrow it. A heat pump also replaces both heating and cooling in one system and is typically cheaper to run than electric, oil, or propane heating, so it can be the better long-term value depending on your local energy prices.
How long does heat pump installation take? A standard ducted heat pump replacement usually wraps up in a day or so; a single-zone mini split in a matter of hours; a multi-zone mini split in a few days; and geothermal far longer, driven mostly by the ground loop. Add time if an electrical panel upgrade is needed, and note that permit acquisition can add days to weeks before work starts.
Can I finance a heat pump installation? Yes. Common options include utility-sponsored financing (often interest-free during a promotional period), PACE loans repaid through property taxes, manufacturer/dealer financing, home equity loans or lines of credit, and personal loans. Compare carefully, some promotional dealer financing jumps to a high rate after the intro period.
How much does it cost to add a heat pump to an existing furnace? Adding a heat pump alongside your gas furnace (a dual-fuel or hybrid system) is a cost REMDB does not price separately; it depends on the heat pump you choose and the controls to tie it into the existing furnace. You keep the furnace as backup for the coldest days while the heat pump handles moderate-weather heating and all cooling, a popular cold-climate approach that avoids replacing a working furnace.
Why are heat pump quotes so different from each other? Because the scope and equipment differ. Several things move the number:
- Different efficiency tiers
- Different warranty terms
- Whether ductwork and electrical work are included
- Contractor overhead
- Factory-authorized status
Always compare on an apples-to-apples basis, specify the same efficiency tier and the same included work across bids.
Where these numbers come from
The installed-cost figures come from NREL's National Residential Efficiency Measures Database (REMDB), 2024 release, which models a retrofit replacement in 2023 dollars and gives a low, mid and high estimate. They are total installed costs, including removing the old equipment and before any rebates, so prices have generally risen since 2023; NREL derived its heat pump costs largely from California and Massachusetts incentive data, so they run high relative to some markets. Work REMDB does not price, such as new ductwork, geothermal ground loops and dual-fuel tie-ins, has no figure here and is described as a cost driver instead.
Proper sizing follows ACCA Manual J. The tax-credit and rebate information reflects current federal rules: the IRS Section 25C credit and the Section 25D geothermal credit both ended after December 31, 2025 under the OBBBA, while the IRA HEAR and HOMES rebate programs remain, with state and utility incentives tracked in the DSIRE database.
Equipment certification data is available through AHRI. Install quality and proper sizing matter more than brand for a heat pump's real-world cost and performance.
