Heat pump cost calculator
A free heat pump cost calculator for US homes. It models heat pump installation cost, heat pump operating cost, and only the heat pump rebates that are actually open in your state.

The cost bands behind the model
These are the same bands the calculator scales by your region. They include equipment, standard labor and a permit. They exclude ductwork, electrical upgrades and anything a contractor discovers after opening a wall.
| System | Low | High |
|---|---|---|
| Like-for-like replacement of an existing ducted system | $7,000 | $16,000 |
| Ducted air source heat pump, new install | $9,500 | $22,000 |
| Cold-climate ducted heat pump | $12,000 | $28,000 |
| Single-zone ductless mini split | $2,800 | $8,500 |
| Multi-zone ductless mini split | $6,500 | $20,000 |
| Geothermal ground source heat pump | $18,000 | $45,000 |
| Heat pump water heater, installed | $1,800 | $5,200 |
| Electrical panel upgrade to 200A | $1,400 | $5,500 |

How the calculation works
The model runs in four stages. Each stage is a pure function with no network access.
- Resolve geography. Your ZIP maps to a state, which supplies the residential electricity price from the EIA, the natural gas price from the EIA, and population-weighted heating degree days from NOAA.
- Estimate the heating load. If you entered an annual heating spend, we back the load out of it using your current fuel and its assumed efficiency, which is the most accurate path. Otherwise we model it from floor area, degree days, envelope quality and build vintage.
- Apply system efficiency. A ducted heat pump is modelled at a seasonal coefficient of performance of 2.6, cold-climate ducted at 2.9, and ductless at 3, each reduced by duct losses of 15 percent for ducted systems and 2 percent for ductless.
- Compare and total. We price the same delivered heat from your current system, subtract it from the heat pump, add only the rebates marked open, and produce a 10-year total and a simple payback.
The full published method, including the limitations and the reasoning behind each constant, is on the methodology page.
Privacy
The calculator has no analytics inside it and sends nothing. It runs against a bundled data table. Nothing is collected unless you ask us to email the estimate, and that request only carries the details you can see on the form.

Ask installers to price this job, not a different one
The range is already on this site, and the calculator will give you a ZIP-level number for free. What you do not have is a bid that uses the same scope. We send your ZIP and that range to installers who work the market, and we tell them to quote that job. You get the emails. You decide.
- We attach the modeled range so the bid has to price that job, not a sales package
- You also get a one-page brief you can hand to any contractor you found yourself
- Phone is optional. No account. If nobody covers your ZIP yet, you still get the brief
