Heat Pump Installation Cost Calculator (2026)
Estimate the installed cost of a ducted central air-source heat pump for any US home, by size, efficiency tier, ductwork, and region.
The short answer
A ducted central air-source heat pump installation for a typical US home runs roughly $10,000–$20,000 all-in, with most projects landing $12,000–$16,000. The four biggest drivers are home size (system tonnage), efficiency tier, whether your existing ductwork is reusable, and your local labor market. Brand premium and complex retrofits push the high end higher.
This calculator covers ducted central air-source systems only. Ductless mini-splits and ground-source (geothermal) heat pumps are priced differently and aren't modeled here.

This is a quick rule-of-thumb size. A proper Manual J load calculation by an HVAC contractor will be more precise — a dedicated sizing calculator on this site is on the roadmap.
What this estimate includes
- Included
- Outdoor unit and matched indoor air handler / coil
- Standard installation labor and crane / lift if needed
- Refrigerant line set and condensate drain
- Basic electrical hookup at the existing panel
- Standard thermostat and basic controls wiring
- HVAC permit and startup commissioning
- Removal and disposal of replaced equipment
- Not included
- Major panel upgrades beyond a standard breaker swap
- Extensive ductwork beyond the selected ductwork add-on
- Asbestos abatement or hazardous-material remediation
- Structural changes to mount the outdoor unit
- Backup heat (electric strips or retained gas furnace)
- Smart-home integrations beyond a standard thermostat
- Federal, state, or utility incentives
These are ballpark estimates for budgeting, not contractor quotes. Actual cost depends on local labor, equipment brand, ductwork, electrical service, and site conditions. Get written quotes from licensed HVAC contractors before deciding.
How this calculator works
We size the system, build a base install cost, layer on efficiency and ductwork, then apply your regional labor market and install difficulty.
- System size (tons)= home size ÷ sq-ft-per-ton for your climate (Hot 500, Warm/Mixed 600, Cold 550, Very Cold 450). We round to the nearest half-ton and clamp to the typical residential range of 1.5–5.0 tons. Larger homes usually need two systems; we'll flag that case.
- Base cost = $3,000 fixed (labor base, permits, electrical hookup, line set, thermostat) plus $1,800 per ton of equipment and installed material.
- Efficiency tier multiplies the base: Standard 1.00×, High-efficiency 1.20×, Premium variable-speed 1.45×.
- Ductwork add-on adds a flat dollar amount: $0 for good reusable ducts, $1,500 for minor modifications, $5,000 for a new duct system.
- Regional × difficulty multiplierscales the whole subtotal by your local labor market (typ. 0.85–1.35) times an install difficulty factor (Standard 1.00, Moderate 1.15, Complex 1.30). The combined multiplier is capped at 1.50× so a single extreme input can't blow up the estimate.
- Range: the point estimate is bracketed ±15% to reflect realistic contractor-to-contractor and site-condition variance.
Frequently asked questions
- How much does it cost to install a heat pump?
- A ducted central air-source heat pump for a typical US home costs about $10,000 to $20,000 installed, with most projects landing between $12,000 and $16,000. Smaller homes in low-cost regions can come in under $9,000; larger homes with premium variable-speed equipment, new ductwork, or panel upgrades commonly cross $25,000.
- How does heat pump cost change with home size?
- Equipment and labor scale roughly with system size, measured in tons of cooling capacity. A typical residential rule of thumb is 450–600 sq ft per ton (more square feet per ton in mild climates, fewer in cold climates). At about $1,800 per ton in installed equipment cost plus a fixed labor base, a 3-ton system runs around $8,400 in base cost and a 5-ton system around $12,000 before efficiency, ductwork, and regional adjustments.
- Does new ductwork add a lot to the install cost?
- Yes. Reusing good existing ductwork is essentially free for the install scope. Modifying or rebalancing existing ducts adds roughly $1,500 on average. A full new duct system (e.g., when converting from baseboard or window-unit heating) commonly adds about $5,000 and can run higher depending on house layout and access.
- Does a high-efficiency heat pump cost more to install?
- Yes. A high-efficiency air-source heat pump (SEER2 17–18) typically costs about 20% more than a standard-efficiency unit. A premium variable-speed system (SEER2 19+) typically costs about 45% more. The trade-off is lower annual operating cost — whether that pays back depends on your climate and electricity rate.
- What's included in a heat pump installation quote?
- A standard installed quote should include the outdoor unit and matched indoor air handler, refrigerant line set, condensate drain, basic electrical hookup at the existing panel, a standard thermostat, HVAC permit, startup commissioning, and disposal of the replaced equipment. Items that often get quoted separately: major electrical panel upgrades, extensive ductwork beyond a minor rebalance, asbestos abatement, structural work to mount the outdoor unit, and backup heat sources.
- Should I get multiple bids?
- Yes — three is standard. Heat pump install bids commonly vary 25% to 40% between contractors for the same home, mostly driven by labor rates, brand sourcing, and how each contractor scopes ductwork and electrical. Compare like-for-like equipment models and total scope, not just bottom-line numbers.
