Heat Pump Cost Calculator: 2026 Installation Planning Tool

Use this calculator to build a planning benchmark for a heat-pump project using current 2026 cost datasets.

It is not a local contractor quote.

Heat-pump pricing varies substantially by:

system architecture
number of zones
equipment tier
building load
ducts
electrical work
climate requirements
labor market
permits

The tool shows the source-backed benchmark it is using rather than pretending one national formula can price every home.

Heat pump cost calculator

Prepare a budget using published national benchmarks and an optional ductwork scenario. These averages describe different project scopes; they are not a local quote or a prediction of your installed price.

Project type

The calculator selects the most directly relevant published benchmark. Single-zone and geothermal defaults describe replacement projects.

Ductwork scenario

Only an explicit full-new selection adds a separate typical ductwork range. Targeted work and unknown duct condition are not priced.

Verified rebate or incentive ($, optional)

Only enter an amount you have verified with the official program. Read the rebate guide for eligibility and source checks. Confirm eligible costs and whether incentives can be combined.

Known contractor quote ($, optional)

Enter the gross quoted amount before incentives. Comparison uses the selected benchmark average, excluding this tool’s extra ductwork scenario.

Optional amounts accept $0–$1,000,000. These are input limits, not a ceiling on project costs or incentives. Leave blank to apply no incentive or quote comparison.

Not automatically priced by this tool

Electrical service or panel upgrades
Permits
Structural work
Specialty access or cranes
Asbestos or environmental remediation
Custom finish work
Geothermal drilling and site complexity
Local labor premiums
Model-specific equipment premiums

The published averages can include some of these items. The tool does not determine their cost for your home or add them automatically. Request an itemized quote and avoid counting work twice.

Published benchmarks used by this calculator

Each row is a separate national average, not the low or high end of one common price range. Scope and survey mix differ between publishers.

Default benchmark, project scope, source, and review date for each project type
Project	Average benchmark	Scope and source	Reviewed
Ducted whole-home	$14,529	Whole-home ducted upfront installed-price average from EnergySage marketplace projects. EnergySage.	2026-10-04
Ductless single-zone	$3,250	Single-zone mini-split average replacement cost. A first-time installation can have a different scope and cost. This Old House.	2026-10-04
Ductless whole-home / multi-zone	$25,957	EnergySage ductless (mini-split) marketplace average, used as a broad reference for this selection. The source does not define a whole-home-only cohort. EnergySage.	2026-10-04
Hybrid / dual fuel	$14,353	Hybrid upfront installed-price average from EnergySage marketplace projects. Retained or replaced furnace scope must be checked in the quote. EnergySage.	2026-10-04
Geothermal	About $17,000	Small/medium-home geothermal average replacement cost. This is not a complete budget for a new ground loop or drilling. This Old House.	2026-10-04

For a separately assumed full-new-ductwork scenario, Angi reports a typical $2,000–$7,500 ductwork range. It is not a ceiling; larger projects can reach $12,000 or more. Benchmarks may already contain ductwork, so do not add the same work twice.

Geothermal’s default is a small/medium-home replacement benchmark. Larger-home projects can exceed $30,000. Ground-loop and drilling conditions can dominate cost; this tool cannot price them from national data.

Data version 2026-10-04.1. Publication dates: EnergySage 2026-03-19; This Old House 2026-08-28; Angi 2026-05-30. All sources reviewed 2026-10-04.

Turn on JavaScript to use the calculator. The calculation happens in your browser; no form data is sent.

Start with the project’s published average. Subtract only your verified incentive, with a minimum net amount of $0. An explicit full-new-ductwork scenario adds the separate $2,000–$7,500 typical ductwork range before that subtraction.

Example: the $14,529 ducted benchmark plus separately assumed full new ductwork gives a $16,529–$22,029 gross planning scenario. A user-verified $3,000 incentive gives $13,529–$19,029 after that incentive. This combined scenario is arithmetic, not an observed local price range; avoid adding ducts already included in the underlying project scope.

A $15,000 gross contractor quote is $471 (about 3.2%) above the $14,529 benchmark. Scope, equipment, ducts, electrical work, permits, labor market, and climate requirements can explain a difference; a higher or lower quote is not automatically bad or good.

Current 2026 Cost Benchmarks

EnergySage's installation guide, updated March 19, 2026, reports these upfront marketplace averages:

Project type	Average upfront cost
Ducted	$14,529
Ductless (mini-split) marketplace projects	$25,957
Hybrid	$14,353
Overall	$15,393

Source: EnergySage Heat Pump Installation

The ductless figure is a broad category average; the source does not define a whole-home-only cohort. The calculator uses it as a reference for whole-home/multi-zone planning, not as a prediction for a particular number of indoor units.

This Old House's guide, updated August 28, 2026, combines Homewyse estimates with a 2026 survey of homeowners who repaired or replaced HVAC equipment within the preceding five years. Its system-type table describes average replacement costs:

Project type	Published replacement benchmark
Central heat pump overall	$10,575 average
Single-zone mini-split	about $3,250
Whole-home air-source	about $8,007
Geothermal small/medium home	about $17,000
Geothermal large home	$30,000+

Source: This Old House Heat Pump Cost

The geothermal figures describe replacement projects. About $17,000 is not a complete budget for a first-time system with new ground loops or drilling; site conditions need an itemized local estimate. The $30,000+ large-home figure is a separate category, not the upper end of a guaranteed price range.

Different datasets use different project mixes.

The calculator identifies the benchmark source for each scenario.

How Much Can New Ductwork Add?

Angi's ductwork guide, updated May 30, 2026, gives a typical installation range of $2,000-$7,500, including materials and labor. This is not a ceiling: its larger-home examples reach $12,000 or more.

Source: Angi Ductwork Installation Cost

Usable existing ducts receive no automatic ductwork add-on. Select a new-ductwork scenario only when the project needs it.

Adding this separate range to a marketplace average is an assumed planning scenario, not a combined observed price dataset. The average or contractor quote may already include ductwork; do not count the same work twice.

What the Calculator Should Include

Choose a system/project type and ductwork scenario, then optionally enter a verified incentive amount and a contractor quote for comparison.

The result identifies the source, gross planning benchmark, selected ductwork adjustment, verified incentive you entered, and resulting net planning figure. It also shows exclusions and unknowns.

The calculation runs in your browser. It does not submit your entries or request a contractor quote. Obtain actual proposals directly from local contractors.

What the Calculator Does Not Price Automatically

The calculator does not estimate:

electrical panel/service upgrades
permit fees
structural work
specialty cranes
asbestos
geothermal drilling complexity
custom finish work

These need local quotes.

Why Doesn't the Calculator Use Square Footage to Pick Tonnage?

Because square footage alone is not a valid heat-pump sizing method.

Equipment size should come from building load.

Can Rebates Lower the Result?

Yes, but the calculator subtracts only a verified user-entered incentive. Confirm program availability, eligibility, and the amount directly with the official program before entering it.

The calculator does not automatically apply a federal tax credit.

What Should You Do With the Estimate?

Use it to:

establish a budget
identify obviously incomplete quotes
compare project architectures
model ductwork/rebate scenarios

Then replace the estimate with actual contractor proposals.

Compare installation costs, review installation planning, and use the installer guide to assess proposals.

Compare Real Heat Pump Installation Quotes

Get multiple local bids based on the same Manual J load and scope.

Prepare for installer conversations

Check the design process and compare written scopes, equipment matches, and installed costs.
