Estimate your heat pump savings and payback
A few choices is all it takes. The assumptions are shown below; this is an indicative estimate, not a quote.
Assumptions: heating load is estimated from home size and climate. Current-fuel cost uses roughly $1.40/therm gas at 92% efficiency, $3.80/gal oil at 85%, and $2.80/gal propane at 90%. Electricity uses your state's typical residential rate (national average about $0.165/kWh if no state is chosen), and heat pump running cost applies a seasonal COP that varies by system and climate (about 2.4 to 4.5). Install figures are typical installed ranges adjusted by a state cost factor. The federal tax credit is 30% of cost, capped at $2,000 for air-source systems (IRS Section 25C) and uncapped for geothermal (Section 25D). If you say the system also replaces air conditioning, we subtract the cost of a separate central AC you would otherwise buy (about $4,000 to $7,500 by home size), since a heat pump cools too. State and utility rebates shown below are additional and vary; income-qualified IRA rebates of up to $8,000 are rolling out where available and are not baked into the payback. Indicative only, not a quote or tax advice.
A heat pump is a single system that both heats and cools your home by moving heat instead of burning fuel, and in 2026 a whole-home air-source install typically runs about $8,000 to $14,000 before incentives. The right choice depends on your climate, your ductwork, and how you size the system, not on the brand a salesperson pushes hardest. This guide walks through what one costs, what it can save, and how to tell whether it fits your house.
What a heat pump actually is
A heat pump runs a refrigerant through a loop that absorbs heat in one place and releases it in another. In summer it pulls heat out of your house and dumps it outside, which is exactly what an air conditioner does. In winter it reverses, pulling heat from the outdoor air (yes, even cold air holds usable heat) and delivering it indoors. Because it moves heat rather than creating it, a heat pump can deliver two to four units of heat energy for every unit of electricity it draws, a ratio engineers call COP.
That efficiency is the whole point. A gas furnace tops out near 95 to 98 percent efficient because it can never return more energy than the fuel contains. A heat pump routinely runs at 200 to 400 percent equivalent efficiency because most of the heat was already outside. If you want the mechanics in plain English, see how heat pumps work, or the plain-language overview at what is a heat pump.
What a heat pump costs in 2026
Installed prices vary widely because “heat pump” covers several system types. A ducted central air-source unit that ties into existing ductwork usually lands between $6,000 and $18,000, with most whole-home projects around $8,000 to $14,000. Ductless mini-split systems run roughly $3,500 to $5,500 per zone, so a multi-zone whole-home setup often totals $8,000 to $20,000. Geothermal systems cost the most upfront, typically $18,000 to $45,000 or more, because burying the ground loop dominates the price.
| System type | Typical installed cost | Best fit |
|---|---|---|
| Ducted central (air-source) | $6,000 to $18,000 | Homes with usable ductwork |
| Ductless mini-split | $3,500 to $5,500 per zone | No ducts, additions, room-by-room control |
| Geothermal (ground-source) | $18,000 to $45,000+ | Long-term owners, lot with loop room |
| Heat pump water heater | $1,500 to $3,500 | Replacing an electric tank |
* Ranges are before tax credits and rebates. Ductwork repair, electrical panel upgrades, and cold-climate models push costs toward the high end.
The single biggest cost driver most homeowners overlook is the work around the equipment: sealing or adding ducts, upgrading an electrical panel, or building a pad for the condenser. For a full breakdown by size and efficiency, see our detailed heat pump cost guide.
What you can get back: credits and rebates
Incentives change the real math significantly. The federal 25C tax credit covers 30 percent of a qualifying heat pump project, up to $2,000 per year, as long as the equipment meets the required ENERGY STAR efficiency tier. It is nonrefundable and claimed on IRS Form 5695, so it offsets tax you owe rather than arriving as a check. On top of that, IRA-funded rebate programs (administered state by state and still rolling out) can provide income-qualified households up to $8,000 toward a heat pump where available.
Availability is not universal, so check your state program before you count on rebate dollars. Stacking a credit and a rebate can cut a $12,000 project by several thousand dollars, but only if your equipment and income qualify. The full picture is in our heat pump tax credit and rebates guide.
Will it work in a cold climate?
Older heat pumps struggled below freezing, and that reputation stuck. Modern cold-climate heat pumps carrying the ENERGY STAR Cold Climate label hold useful capacity down to about 5 degrees Fahrenheit (roughly minus 15 Celsius) and keep working below that, just less efficiently. In much of the country a properly sized cold-climate unit heats an entire house through winter on its own.
When temperatures fall past the point where the heat pump can keep up, auxiliary heat kicks in. That is usually electric resistance strips, or in a dual-fuel setup, a gas furnace that takes over on the coldest days. You will also notice the outdoor unit periodically run a defrost cycle, which briefly blows cooler air indoors and is completely normal.
A right-sized cold-climate heat pump is a primary heating system in most of the US, not a backup.
Getting the size right
Sizing is where good installs separate from bad ones. Capacity is measured in tons, and a common rough rule is 20 to 30 BTU per square foot, which works out to about one ton per 400 to 600 square feet. But that rule ignores insulation, windows, ceiling height, air leakage, and climate, so treat it only as a sanity check.
The real answer is a Manual J load calculation, which any competent installer performs before quoting. Oversizing is the most common mistake: a too-large system short-cycles, turning on and off rapidly, which wastes energy, wears out the compressor, and leaves humidity in the air. Undersizing leaves you cold on design-day extremes. Our heat pump sizing guide walks through the numbers.
How to read efficiency ratings
Post-2023 equipment is rated with updated metrics. SEER2 measures cooling efficiency over a season, HSPF2 measures heating efficiency, and higher numbers mean lower running costs. These replaced the older SEER and HSPF ratings, so do not compare a 2026 SEER2 number directly against an older SEER figure.
Higher-efficiency equipment costs more upfront but draws less electricity every hour it runs, and it is usually what qualifies for the federal credit. Whether the premium pays back depends on your climate and rates. We break down SEER2, HSPF2 and COP so you can judge the tradeoff instead of chasing the biggest number.
How to choose without getting oversold
Start with your house, not the catalog. If you have sound ductwork, a ducted air-source system is usually the simplest swap. No ducts, or an addition to heat, points toward a mini-split. Planning to stay 15-plus years with room in the yard makes geothermal worth pricing out. New systems now use lower-GWP refrigerants like R-454B or R-32 as legacy R-410A is phased down, so ask what the equipment uses.
Then get three itemized quotes and compare them line by line. A good quote shows the Manual J result, the exact model and its SEER2 and HSPF2 ratings, the air handler or indoor unit, and any electrical or duct work separately. Vague quotes hide upsells. Our guides on reading heat pump quotes and the installation process show what a fair proposal looks like.
A heat pump is a long-lived purchase; most last 12 to 15 years or more with basic upkeep. Size it right, buy the efficiency your climate justifies, claim the incentives you qualify for, and it will heat and cool your home for less than the fossil system it replaces. Take the pieces one at a time and the decision is far less daunting than the sticker price first suggests.
