Most “heat pump cost” pages give you a guess dressed up as a range. This one doesn’t: the numbers below come from TECH Clean California program data — 46,963 completed heat pump installations across 54 California counties — not a contractor survey or an industry estimate. A ducted heat pump installed comes out to a $20,066 median (25th–75th percentile: $16,013–$26,128). A ductless (mini-split) system runs a $12,625 median ($8,200–$20,110). This is California program data specifically, so treat it as a real-install benchmark from one large, well-documented market rather than a national number — your local labor rates and incentives will move it.
Ducted vs. ductless: the split that matters most
The gap between ducted and ductless isn’t just equipment — it’s what has to happen to the house. A ducted system reuses (or extends) existing ductwork and typically replaces a central air handler; a ductless mini-split needs no ducts at all, which is why the low end of its range runs well under the ducted low end. But ductless systems also carry a wider spread ($8,200 to $20,110) than ducted ($16,013 to $26,128) — multi-zone ductless jobs with 3-4 indoor heads can cost as much as a full ducted replacement, while a single-zone job can be a fraction of it. See Central Air vs. Mini-Split for how to tell which category your house actually falls into.
Cost per ton falls as the system gets bigger
Among ducted systems, cost per ton of capacity drops steadily as tonnage rises: $9,421/ton for systems under 2 tons, down to $4,721/ton for 4–5 ton systems. That’s not a quirk of this dataset — a lot of the cost in a heat pump installation is fixed (permit, commissioning, electrical work, line-set routing) regardless of unit size, so it gets diluted across more capacity on a bigger job. The uptick at 5+ tons ($5,999/ton) comes from a much smaller sample (363 jobs) skewed toward larger or commercial-adjacent homes — don’t read too much into it.
What this means for your quote: if two contractors quote wildly different totals for the same house, check whether they sized the equipment the same way first. A correctly-sized 3-ton system will often cost less and perform better than an oversized 4-ton system chosen “to be safe” — oversizing is a real failure mode, not a cost-per-ton bargain.
What actually drives the price
Ducted vs. ductless is the single biggest lever, covered above. Past that:
- Electrical panel capacity. Heat pumps need a dedicated 240V circuit. In this dataset, jobs flagged for an electrical upgrade ran a median of $20,668 versus $20,011 for jobs that didn’t need one — a real but modest premium (about 5% of ducted installs needed one). The IRA has a separate credit for the panel upgrade itself.
- Cold-climate equipment. A standard heat pump loses capacity below about 25–35°F and needs backup heat; a cold-climate model (rated to hold capacity at 5°F) costs more up front but skips the backup-heat conversation entirely. See Heat Pump vs. Gas Furnace for when that trade-off is worth it.
- Duct condition and replacement. If existing ductwork needs replacing rather than reusing, that’s a separate line item on top of the ranges above.
- Home size and heating/cooling load. Bigger homes need more capacity, which — per the chart above — actually brings the per-ton price down even as the total goes up.
Incentives, and what they net out to
The median incentive in this dataset was $3,000 for ductless systems and $1,000 for ducted systems — TECH Clean California program incentives specifically, which vary by income tier and utility territory and won’t be available outside that program. Nationally, the federal IRA Section 25C credit covers 30% of a qualifying heat pump’s cost, up to $2,000/year, and a separate credit of up to $600 covers a qualifying electrical panel upgrade. On a $20,000 ducted installation, the federal credit alone brings net cost to roughly $18,000 before any state or utility incentive layered on top — confirm current terms at ENERGY STAR before budgeting, since eligible-equipment lists and credit terms change annually.
FAQ
Q: Is a heat pump worth the cost compared to a gas furnace?
A: It depends on your climate and your local electricity-to-gas price ratio, not on the heat pump’s price tag alone. In mild-to-moderate climates a heat pump is usually cheaper to run than gas heat and unlocks the IRA credit; in very cold climates with cheap gas the operating-cost case is tighter. See Heat Pump vs. Gas Furnace for the full comparison and the break-even math.
Q: Why is my ductless quote higher than the “ductless is cheaper” range I’ve read elsewhere?
A: Multi-zone ductless systems (3-4 indoor heads on one outdoor unit) scale up fast — the ductless range here runs to $20,110 at the 75th percentile, close to the ducted median. A single-zone quote should land well under that; if a multi-zone quote is near the top of the range, ask what’s driving it (zone count, cold-climate equipment, or electrical work).
Q: Does a bigger heat pump cost more per ton or less?
A: Less, in this data — cost per ton drops from $9,421 for systems under 2 tons to $4,721 for 4-5 ton systems, because fixed costs like permitting and commissioning get spread across more capacity. That’s a reason to get sizing right (a correctly sized system can cost less than an oversized one), not a reason to size up on purpose.
Q: What’s included in “installed cost” here?
A: Equipment, labor, and commissioning for a complete working system. It does not separately itemize permit fees, though those are typically included in a contractor’s total quote. Electrical panel upgrades and duct replacement, where needed, are reflected in the dataset’s median (see above) but add to any individual quote that requires them.
Q: Are these prices current for 2026?
A: The dataset reflects completed TECH Clean California installations aggregated in September 2026. Get 2-3 local quotes for your specific home — this page exists to help you evaluate whether a quote is in a reasonable range, not to replace one.
