Last updated: July 2026 · Based on 2026 US installed pricing
A heat pump costs $4,000 to $9,000 installed for a typical ducted air-source system in 2026, with most homeowners paying around $5,500–$7,000. But the full range is wide — a single-zone ductless mini-split can start near $3,500, while a geothermal system runs $15,000–$35,000. What you pay depends on the system type, size, efficiency, your existing ductwork, and — importantly — the rebates and tax credits available, which can cut thousands off the sticker price. This guide breaks down every cost and shows where the real savings are.
Heat Pump Cost by Type (2026, Installed)
| System type | Typical installed cost | Best for |
|---|---|---|
| Ductless mini-split (single zone) | $3,500–$5,500 | One room / addition |
| Ductless multi-zone (2–4 heads) | $7,000–$14,000 | Whole home, no ducts |
| Air-source (ducted, central) | $4,000–$9,000 | Homes with ductwork |
| Geothermal (ground-source) | $15,000–$35,000 | Long-term, lowest bills |
Cost by Size (Tonnage)
Heat pumps are sized in tons — a measure of heating and cooling capacity, not weight. A bigger home needs more capacity, which raises the cost. Rough installed ranges for ducted air-source systems:
| Size | Home size (approx.) | Installed cost |
|---|---|---|
| 2 ton | Up to 1,000 sq ft | $3,500–$5,500 |
| 3 ton | 1,200–1,800 sq ft | $4,500–$7,000 |
| 4 ton | 1,800–2,400 sq ft | $5,500–$8,500 |
| 5 ton | 2,400–3,000 sq ft | $6,500–$10,000 |
What Drives the Price
- Size (capacity): measured in tons; a bigger home needs more capacity, raising cost.
- Efficiency (SEER2/HSPF2): higher-efficiency units cost more upfront but cut running costs and unlock bigger rebates.
- Ductwork: reusing good existing ducts keeps cost down; new or repaired ducts add $2,000–$5,000+.
- Backup heat and electrical: adding electric backup strips or upgrading your panel adds cost.
- Cold-climate models: hyper-heating units that perform below freezing cost more but may be essential in northern climates.
- Labor and region: installation rates vary widely by market.
Rebates and Tax Credits Can Cut Thousands
This is where heat pumps get much more affordable than the sticker price suggests. Federal tax credits and state or utility rebates can significantly lower the net cost of a qualifying high-efficiency heat pump — in many cases by thousands of dollars. Because these programs change year to year and vary by location and income, check the current federal energy-efficiency tax credit and your local utility’s rebate program before buying. The savings are often large enough to make a higher-efficiency unit the cheaper choice over its life, and sometimes cheaper upfront than a lower-efficiency model after incentives.
Running Costs: The Other Half of the Math
A heat pump’s purchase price is only part of the picture — it replaces both a furnace and an air conditioner in one system, and typically costs less to run than electric resistance heat or older systems. In moderate climates, a heat pump can cut heating costs substantially versus baseboard electric or propane. In very cold climates, it relies more on backup heat, which narrows the savings. Pairing an efficient heat pump with the rebates above is what makes the long-term economics work.
Repair vs. Replace
If your heat pump is under 10 years old, most faults are worth repairing — a failed capacitor or contactor is a few hundred dollars. Past 12–15 years, or when a major component like the compressor fails, replacement usually makes more sense. If your unit is having trouble, first check our guides on a heat pump not heating, not cooling, and how to fix a heat pump — many “failures” are just a dirty filter or a setting.
FAQ
How much does a heat pump cost to install in 2026?
A typical ducted air-source heat pump runs $4,000–$9,000 installed, with most homeowners around $5,500–$7,000. Ductless mini-splits start near $3,500 for a single zone; geothermal systems are far higher at $15,000–$35,000. Rebates can cut thousands off these figures.
Is a heat pump cheaper than a furnace and AC?
A heat pump replaces both heating and cooling in one system, so upfront it often costs less than buying a separate furnace and AC. Running costs are usually lower too, especially in moderate climates, though very cold regions may need backup heat that narrows the savings.
How long does a heat pump last?
Most heat pumps last 12–15 years, sometimes longer with good maintenance. Because they run year-round for both heating and cooling, they tend to wear slightly faster than a furnace that only runs in winter.
What size heat pump do I need?
As a rough guide, about 1 ton per 500–600 sq ft, but proper sizing depends on insulation, climate, windows, and ceiling height. A contractor should perform a Manual J load calculation rather than just going by square footage — an oversized heat pump short cycles and an undersized one cannot keep up.
