A new whole-home heat pump typically costs between $17,000 and $28,000 installed, depending on your home’s size and the type of system you choose. That price includes both equipment and professional installation. Federal tax credits and state rebates can knock thousands off the final bill, bringing some projects closer to the cost of a traditional furnace and AC combo.
Whole-Home Heat Pump Costs by House Size
The biggest factor in what you’ll pay is the size of your home. National averages for a complete heat pump installation, including equipment and labor, break down like this:
- 1,500 to 2,500 sq ft: $17,000 to $23,000 (median around $19,500)
- 2,500 to 5,500 sq ft: $22,500 to $28,000 (median around $25,000)
- 5,500+ sq ft: $26,000 to $30,000 (median around $29,000)
These figures represent the middle range of what homeowners actually pay. About 20% of projects come in lower, and 20% come in higher, depending on factors like ductwork condition, local labor rates, and system brand.
How System Type Changes the Price
Not every heat pump installation is the same scope. A single-zone system that heats and cools one area of your home costs far less than a whole-home ducted system, and the type you need depends on what you’re trying to accomplish.
A single-zone heat pump, the kind that handles one room or area, runs $5,400 to $8,500 installed, with a median around $6,600. These are popular for additions, garages, or supplementing an existing system in the room that never seems comfortable.
Ductless mini-split systems, which mount individual units on walls in different rooms, scale with the number of zones you need. A single-zone ductless system runs $2,000 to $6,000. A dual-zone setup costs $3,200 to $10,500. Three or more zones push the price to $5,500 to $13,000 or higher. The equipment itself is often cheaper per zone than a ducted system, but costs add up quickly once you’re conditioning multiple rooms.
Ducted heat pumps, which use your home’s existing ductwork like a traditional furnace and AC, average about $15,300 after state and local incentives. Ductless systems average higher at around $19,500 because multi-zone installations require more indoor units and refrigerant lines. Hybrid systems that pair a heat pump with a gas furnace for extremely cold days average about $15,700.
Geothermal Systems Cost Significantly More
Ground-source (geothermal) heat pumps pull heat from underground instead of the outdoor air. They’re more efficient, especially in very cold climates, but the installation involves drilling or trenching on your property. That pushes total costs to $15,000 to $40,000 or more in 2025.
The type of ground loop your property needs has the biggest impact on price. Horizontal loops require a large yard and less excavation. Vertical loops require deep drilling, which costs considerably more but works on smaller lots. If your property has a pond or other water source, an open-loop system can cut excavation costs significantly. Soil conditions, site accessibility, and local permit requirements can each add thousands to the project. Some complex installations have exceeded $70,000.
What Drives the Cost Beyond Equipment
The heat pump unit itself is only part of the total. Labor typically runs $2,000 to $4,500 for a standard installation, with HVAC technicians charging $75 to $150 per hour. A straightforward swap where you’re replacing an existing system and reusing ductwork sits at the lower end. A first-time installation that requires new ductwork, electrical panel upgrades, or refrigerant line runs will cost more.
System capacity also matters, though not in a perfectly predictable way. A 2-ton system (appropriate for a smaller home) averages around $16,200 before incentives, while a 4-ton system (common for mid-size homes) averages about $22,300. Larger systems for bigger or draftier homes can run higher, but pricing varies widely by brand and installer. Getting multiple quotes is one of the most reliable ways to avoid overpaying.
Tax Credits and Rebates That Lower Your Cost
The federal government currently offers a tax credit of up to $2,000 per year for qualifying heat pump installations. Your system needs to meet the highest efficiency tier set by the Consortium for Energy Efficiency, and starting in 2025, you’ll need to include the manufacturer’s qualification ID number on your tax return. This credit is available for systems installed through December 31, 2025.
Beyond the federal credit, the Home Efficiency Rebates program (HEEHRA) provides additional money for income-qualifying households. In states where the program is active, households earning less than 80% of their area’s median income can receive up to $8,000 in rebates for a heat pump. Households earning between 80% and 150% of the area median income qualify for up to $4,000. These are point-of-sale rebates, meaning they reduce what you pay upfront rather than requiring you to wait for a tax refund. Multifamily properties may qualify for up to $14,000 per unit.
Many states and utilities stack their own rebates on top of federal incentives. Depending on where you live and your income, it’s realistic to reduce a $20,000 installation by $4,000 to $10,000 through combined programs.
How Long a Heat Pump Lasts
A typical heat pump lasts 10 to 15 years. That’s shorter than a gas furnace, which generally runs 15 to 20 years. The difference comes down to workload: a heat pump runs year-round for both heating and cooling, while a furnace only operates during heating season. A separate air conditioner paired with a furnace also typically lasts 15 to 20 years because it only runs in summer.
The tradeoff is that a heat pump replaces both your furnace and your air conditioner with a single system. So while the unit itself may need replacing sooner, you’re maintaining one piece of equipment instead of two. Regular maintenance, particularly keeping the outdoor unit clear and changing filters, helps push your system toward the longer end of its lifespan. In moderate climates where the system doesn’t work as hard through extreme cold, some units last well beyond 15 years.
