Heat Pump Cost in 2026 (By Size & Type)

What a heat pump costs depends less on the equipment than on what your house already has. If there is usable ductwork, a heat pump is close to a swap. If there is not, the job becomes either a duct installation or a multi-zone ductless system, and the number roughly doubles. Tonnage, efficiency tier and local labour rates move it as well, but ductwork is the fork in the road. The tables below break the cost out by type and by size, and the incentives section covers what comes back off the top.

Installed cost by type

The single biggest fork in the road is ducted versus ductless. If your home already has decent ductwork, a central (ducted) heat pump is almost always the lower-cost option because one indoor air handler serves the whole house. Ductless mini-splits skip ducts entirely, but you pay for a separate indoor head in each room or zone, and there’s little volume discount for adding zones. That’s why a fully ductless home can cost more than a ducted one even though the idea sounds simpler.

Single-zone mini-splits are the entry point — a 9,000–12,000 BTU head for one room often runs $1,500–$3,100 installed, scaling up to around $5,500 for a 24,000 BTU unit. The math turns once you go whole-home: by the time you wire and run refrigerant lines to four or five indoor heads, you’re often past what a ducted system would have cost.

Installed cost by size (tonnage)

Heat pumps are sized in tons, from about 1.5 tons (18,000 BTU) up to 5 tons (60,000 BTU). Bigger isn’t better — an oversized unit short-cycles, wastes energy, and wears out faster. A pro should size yours with a Manual J load calculation, not a rule of thumb. The table below shows ballpark installed ranges for ducted air-source units at standard efficiency; high-efficiency models push the top of each range higher.

Square-footage figures are rough — climate, insulation, ceiling height, and window count all shift the load. Treat these as a starting point, then let a Manual J calculation set the real number.

What drives the price

Two homes can get wildly different quotes for the “same” heat pump. Here’s where the money goes:

• System size. The biggest single driver. Larger tonnage means a bigger outdoor unit, matched indoor components, and more labor.
• Efficiency (SEER2 and HSPF2). The current federal minimums are 14.3 SEER2 and 7.5 HSPF2. Stepping up to high-efficiency (16+ SEER2, often a variable-speed inverter) can add several thousand dollars but lowers operating cost, and is usually required to qualify for utility rebates.
• Ductwork. If you have sound ducts, you save big. If ducts are missing or badly deteriorated, new or reworked ductwork commonly adds $2,000–$8,000 depending on home size and layout.
• Electrical. Heat pumps run on electricity, and an older 100-amp panel near capacity may need an upgrade to 200 amps — typically $1,500–$4,500 including a new circuit.
• Region and labor. Labor is roughly 40–55% of the total, and rates vary 30–40% by metro. In high-cost areas like coastal California, labor can run 35–50% above the national average, which is why local quotes often look higher than national price guides.

Operating cost vs. a furnace + AC

The sticker shock fades when you remember a heat pump replaces two machines — your furnace and your air conditioner — with one. Compared head-to-head against a new furnace-plus-AC, the installed-cost gap is often only a few thousand dollars, not the $10,000-plus it looks like at first glance.

On running cost, there is no national winner: at national-average prices a heat pump and a gas furnace land close, and the margin either way varies widely. The deciding factor is your local electricity-to-gas price ratio: the break-even is roughly your heat pump’s seasonal efficiency divided by your furnace’s — at the federal minimum of 7.5 HSPF2, a seasonal coefficient of performance near 2.2, against a 95 percent AFUE furnace, that lands close to 2.3 to 1 rather than the 3.5 to 1 often quoted. In mild climates the savings are largest; in very cold climates with cheap natural gas, a high-efficiency furnace can still be competitive in the coldest months. If you’re weighing whether to keep an aging system running or swap it, our guide on whether to repair or replace your AC walks through the same break-even math for cooling equipment.

Tax credits and California rebates in 2026

This is the part that changed for 2026, so read carefully. The federal 25C Energy Efficient Home Improvement Credit — the one that gave up to 30% of project cost, capped at $2,000 for a qualifying heat pump — expired on December 31, 2025 under the legislation passed in mid-2025. Air-source heat pumps installed in 2026 do not qualify. (If your system was installed and placed in service on or before Dec. 31, 2025, you can still claim it on your 2025 return when you file in 2026.) Geothermal (ground-source) heat pumps had their own 30% credit under Section 25D, but the same 2025 budget law (the One Big Beautiful Bill Act) terminated that credit too — it ended December 31, 2025. So for 2026 there is no federal residential tax credit for either an air-source or a geothermal heat pump; only systems placed in service on or before that date can still be claimed. State and utility rebates are now the only incentives for either type.

With the federal credit gone for air-source units, state and utility rebates are now the main savings. In California, the statewide TECH Clean California initiative and local utility programs are where the remaining money is. TECH’s incentive pools are finite and have been fully subscribed in the past, so check current availability on the program’s own site rather than assuming it. SMUD raised its rebates in February 2026 and now offers up to $3,000 for a gas-to-electric heat pump HVAC conversion with a variable-stage system, $2,000 for a qualifying two-stage system, and $1,000 for an electric-to-electric upgrade. LADWP offers up to $2,500 per ton for heat pump HVAC, at amounts increased for equipment installed on or after November 1, 2025. Both were open as of August 2026. These programs are funding-limited and open, close, and change often, so confirm current offers with your own utility before you sign anything.
