Heat Pump Cost in 2026: Ducted, Ductless, Cold-Climate & Geothermal

Why "heat pump" covers such a wide price range

All four types move heat rather than burn fuel to create it, but they differ enormously in how they do it and what that costs to install. A standard ducted heat pump is close kin to a central air conditioner, if the ductwork already exists, the install is similar in scope and price. A geothermal system instead moves heat to and from the ground itself, which means drilling or trenching a loop field before the indoor equipment is even touched: the loop field alone is typically 50-70% of the total project cost.

Standard ducted air-source heat pumps

This is the type most people mean by "heat pump": an outdoor unit and indoor air handler connected to existing ductwork, functioning as both the home's heating and cooling system in one. When ductwork already exists and is in good condition, the install cost tracks closely with a central AC replacement: $4,200–$7,600 installed is typical. Where ductwork needs to be added or substantially modified, add the ductwork cost separately: it is not included in heat pump pricing itself.

The real question for this type isn't the heat pump's price, it's whether it can replace a furnace entirely in your climate, or whether it needs backup electric resistance heat (strip heat) for the coldest days, which is where cold-climate models below become relevant.

Ductless mini-split heat pumps

A ductless system skips the air handler and ducts entirely, instead running refrigerant lines from an outdoor compressor to one or more wall- or ceiling-mounted indoor units, each independently controlled. This makes it the practical option for additions, converted garages, or any home with no existing ductwork: running new ducts through finished walls is often more disruptive and expensive than going ductless instead. A single zone (one indoor unit, one room or open area) runs $3,500–$8,000 installed; adding zones for more rooms scales the cost up, with a 3-5 zone system commonly landing $6,500–$14,500.

Cold-climate heat pumps

Standard heat pumps lose efficiency as outdoor temperatures drop, and older models could struggle to keep a home warm much below freezing without heavy reliance on backup electric heat. ENERGY STAR's Cold Climate Heat Pump designation exists specifically to identify equipment built for this: cold-climate models use variable-speed compressors and refrigerant designed to keep extracting usable heat from outdoor air down to 0°F or lower, which is why they've become the standard recommendation for heat-pump installs in northern climates rather than a niche upgrade. The added engineering typically adds 20-40% over a standard unit of the same size, putting a whole-home cold-climate system in the $8,000–$25,000+ range depending on size and number of zones: premium fully variable-speed systems for larger homes can run higher still.

Geothermal (ground-source) heat pumps

Geothermal systems exchange heat with the relatively constant temperature underground rather than the more variable outdoor air, which makes them the most efficient option on this list, and by far the most expensive to install. The cost is dominated by the ground loop: a horizontal loop (buried in a trench, needing more yard space) commonly runs $25,000–$40,000; a vertical loop (drilled boreholes, needed on smaller lots) runs $25,000–$55,000; a pond or lake loop, where a property has access to a suitably sized and deep body of water, is the cheapest option at $3,000–$6,000 for the loop itself. A typical 3-ton residential system lands around $20,000–$27,000 installed all-in; drilling into hard rock, a larger home's load, or a full ductwork rebuild on top can push the project to $50,000–$60,000 or more.

Geothermal's payback period is long, often a decade or more even with incentives, which makes it a decision driven by how long you plan to stay in the home as much as by the heating bill savings themselves.
