Heat Pump Installation Cost 2026: $8,000–$18,000 Typical

Installing a common ducted air-source heat pump in a US single-family house — about 2 to 4 tons, mid-tier efficiency, outdoor unit and indoor air handler or coil where the old equipment sat, with the ducts kept in place — often clusters around $8,000–$18,000. The wider national spread, about $4,000–$30,000, covers a single-zone ductless mini-split in a lower-cost area at the low end and a cold-climate ducted unit, dual fuel, multi-zone ductless, a hard-to-reach install, or electrical work that the heat pump forces at the high end. Geothermal, all-new ducts, or a house that needs a service upgrade can clear that spread. This is a planning range, not a quote.

The rows below are ways to read one install. They are not added together. Dual fuel replaces the ducted band when the bid keeps a gas furnace for the coldest days. It is not a second system stacked on a heat pump you already priced.

Scope	Typical cost
Ducted air-source heat pump, about 2 to 4 tons, existing ducts	$8,000–$18,000
Dual fuel, a heat pump plus a gas furnace	$12,000–$22,000
Wider national spread, from a single-zone ductless unit to a hard multi-zone or cold-climate install	$4,000–$30,000

A heat pump is not a furnace with a different badge, and it is not only a summer air conditioner. One outdoor unit moves heat both ways. That is why this page is its own guide, next to the furnace replacement and central air replacement bands, instead of a footnote on either.

The carton price is not the job. Equipment at a supply house can look like a few thousand dollars. The bid is the permit, the line set, the electrical whip and disconnect, startup, and haul-away. Square-foot rules of thumb are a poor way to pick tons. A tight two-story and a leaky ranch with the same floor area are not the same load. Price the heat pump and the ducts you have, not a chart you saw on a forum.

What the range includes

The typical band assumes an existing single-family house with ducts, one ducted air-source heat pump of a common residential size — often something like 2 to 4 tons, which is a description, not a sizing rule — set where the old outdoor unit and air handler or coil sit. It includes the outdoor unit, the indoor air handler or matched coil, connection to the existing supply and return, a line-set replacement or a flush when the contractor says the old line is acceptable, refrigerant, a disconnect if required, a permit where the city requires one, startup, and haul-away of the old equipment. A basic thermostat swap is often included. A communicating thermostat and a zoning panel are not.

An easy pad swap in a lower-cost area, with a short line set and a circuit that already fits, sits toward the floor of the typical band. An attic air handler, a long buried line set, a cold-climate model, or a dual-fuel pair that keeps a gas furnace sits at the top of that band and leaves it.

The floor of the national spread, near $4,000, is usually a single-zone ductless mini-split on a simple wall, in a lower-cost market — not a whole-house ducted system someone discounted. Zone and BTU ranges for that mini-split are on the ductless mini-split guide. The top, toward $30,000, is where multi-zone ductless, a cold-climate ducted install with difficult access, dual fuel, new duct branches, and an electrical service that has to grow usually land. Geothermal and a full duct replacement can clear that top. Treat a number above it as a different scope and ask which driver caused it.

A like-for-like air-conditioner condenser and coil, when the furnace stays for heat, is often discussed closer to $5,500–$9,500 on the central air guide. A mid-efficiency gas furnace on the same ducts is often discussed around $4,000–$6,500 on the furnace guide. A matched gas furnace and central air conditioner replaced in one visit, without a heat pump, is the AC and furnace guide. Dual fuel — a heat pump for most of the year and a gas furnace for the coldest days — is often discussed from the top of this typical band into the wider spread, roughly $12,000–$22,000, when both pieces of equipment and the controls are in one bid. Those figures are cross-checks, not quotes.

None of the bands include all-new ductwork, asbestos abatement, a main electrical panel or service upgrade, geothermal, or a separate envelope job such as attic insulation. If the panel cannot take the breaker the heat pump needs, price that on the electrical panel guide. Do not fold the service into the heat-pump bid, and do not fold the heat pump into the panel bid.

What moves the price

Driver	How it changes the bid
System type	A ducted air-source unit on ducts you keep is the typical band. A single-zone ductless unit is often cheaper. Multi-zone ductless and dual fuel leave the typical band.
Climate rating	A standard air-source unit is the planning job in mild winters. A cold-climate heat pump, built to keep capacity farther below freezing, costs more to buy and sometimes more to install.
Tonnage and efficiency	Larger equipment and higher SEER2 / HSPF2 ratings cost more. Oversizing for a cold room is still the wrong fix when the attic is bare.
Access	A condenser on a clear pad with a short line set is the planning job. An attic air handler, a crawl-space coil, or a unit that must be craned is labor.
Line set and pad	A long, buried, or undersized line set is often replaced rather than reused. A crumbling pad is a small line; a relocated pad is not.
Electrical	A like-for-like circuit swap is ordinary. A heat pump that needs a larger breaker, a new run, or a panel that is already full is a different project.
Ducts and backup heat	Leaky or undersized ducts can cost as much as the equipment. Strip heat, a dual-fuel furnace, or emergency heat kits add scope this range does not assume.

If the old system was a gas furnace and a separate air conditioner, say whether the furnace stays, goes, or becomes the dual-fuel backup. A bid that removes the furnace without pricing strip heat or a backup plan is not comparable to a dual-fuel bid. Price a furnace-only swap on the furnace guide when that is the real project.

A room that stays cold at the outside wall is not automatically a heat pump that is too small. Thin attic insulation and tired windows lose heat you already paid to move. Price those on the attic insulation guide before you buy a larger tonnage. Oversizing short-cycles the unit and can leave the house clammy in summer. It does not fix a bare attic.

Some utilities and rebates care about the AHRI match, the HSPF2 rating, and whether the install is ducted or ductless. A bid that will not list the outdoor and indoor model numbers is not ready to compare, and it is not ready for a rebate form either.

DIY or hire

Hire. Handling refrigerant requires EPA Section 608 certification, and the electrical connection is not a homeowner add-on. Most jurisdictions treat the change-out as licensed, permitted work. Manufacturers also tie warranties to a licensed install and a commissioning record.

Homeowner work stops at the filter, the thermostat batteries, keeping plants and snow off the outdoor coil, and pouring a cup of vinegar through a condensate line that clogs. None of that is an installation. Do not open the line set, “top off” refrigerant, or swap the outdoor unit because the pad looks open.

Hire even more clearly when the air handler is in a crawl space or a tight attic, when the job is dual fuel, when the panel is full, or when the line set is buried. Those are the jobs where a cheap weekend mistake becomes a leak, a tripped main, or a warranty denial.

Repair or replace

Repair when the heat pump is under about 10 to 12 years old, it has been maintained, the compressor and coils are intact, and one part failed: a capacitor, a contactor, a fan motor, a reversing valve, or a defrost control. Ask for the repair price next to a replacement price. A repair that is a large fraction of a new system, on a unit already near the end of its life, is usually the wrong purchase.

Replace when the compressor failed, a coil is leaking, the equipment is past about 12–15 years — a service life people plan around, not a warranty — it still uses R-22, or this is the second significant repair in a short span. A new thermostat on a heat pump that will not reverse into heat is still the old heat pump.

Have the technician check charge, airflow, and the defrost cycle before you choose. Uneven rooms are not, by themselves, proof that the heat pump is done. They are often ducts, a closed register, or an envelope problem. Have those checked before you buy tons you do not need. If winter backup is the real question, compare a repair, a new heat pump, and dual fuel as three scopes — not as one vague “HVAC upgrade.”

How to use this number

Ask for bids that state the AHRI-matched outdoor and indoor models, the tonnage, the SEER2 and HSPF2 ratings, whether the unit is standard or cold-climate, whether the line set is new, what happens to the old furnace if there is one, whether strip heat or dual fuel is included, who pulls the permit, and who hauls the old equipment away. Compare a ducted air-source swap on existing ducts with the typical band. Compare a single-zone ductless unit with the floor of the wider spread. Compare dual fuel, multi-zone ductless, or a panel upgrade with the top of that spread and with the central air, furnace, and electrical panel guides so the heat pump stays visible as its own line.

A very low bid on a “whole-house heat pump” is a reason to ask whether the indoor unit, the line set, backup heat, and the electrical circuit are included, not a reason to celebrate. A high bid should point at cold-climate equipment, dual fuel, ducts, access, or the electrical service. Two or three local bids on the same system type and the same location are the number that matters. How this site sets the band is explained on the methodology page.
