The Honest 2026 Picture: What Changed
Most heat pump calculators online still show a 30% / $2,000 federal tax credit. That is no longer correct. The One Big Beautiful Bill, signed July 4, 2025, ended both the Section 25C energy-efficient home improvement credit (the $2,000 heat pump credit) and the Section 25D residential clean energy credit (which covered geothermal) for anything placed in service after December 31, 2025.
For a 2026 install there is no federal tax credit. What survives is the HEEHRA point-of-sale rebate (up to $8,000, income-qualified) plus a patchwork of state and utility programs. This calculator models that reality — so your numbers are real, not based on an incentive that expired.
Savings by Current Fuel Type
The single biggest driver of whether a heat pump saves money is what you heat with today. Replacing an expensive or inefficient fuel produces large savings; replacing cheap natural gas can be close to break-even on running cost.
| You heat with… | Typical running-cost result | Why |
|---|---|---|
| Electric resistance | Big savings (50–65%) | A heat pump delivers 2.5–3× the heat per kWh |
| Propane | Big savings | Propane is expensive per delivered BTU |
| Heating oil | Usually saves | Oil prices are volatile and high |
| Natural gas (warm/mixed) | Modest savings | Little backup heat needed; cooling upgrade helps |
| Natural gas (cold, cheap gas) | Can cost more to run | Backup heat + expensive electricity vs cheap gas |
Why the Backup Heat Matters (and Most Tools Ignore It)
Below a heat pump’s balance point — the outdoor temperature where it can no longer meet your home’s full heat loss — it falls back on electric-resistance strip heat at a COP of 1.0. In a cold climate that backup can be 10–22% of seasonal heating with a standard unit, and it is expensive. A cold-climate (ccASHP) variable-speed unit holds capacity down to about 5°F and cuts that backup to a few percent. This is the difference between a heat pump that saves money in Minnesota and one that doesn’t — and it is built into this calculator’s effective seasonal COP.
How to Use Your Actual Bills (Most Accurate)
Climate-and-square-footage estimates are fine for a first look, but the accurate path is to switch the calculator to “I know my annual usage” and enter your real consumption: therms of natural gas, gallons of oil or propane, or kWh for electric heat. Your last 12 months of utility bills give you this number directly, and it removes all the modeling uncertainty from the heating side.
Heat Pump Install Cost (2026)
| System | Installed cost | Best for |
|---|---|---|
| Ductless mini-split (1 zone) | $4,000–$8,000 | Single room, addition, no ducts |
| Ducted air-source (whole home) | $12,000–$20,000 | Existing ductwork, full replacement |
| Multi-zone ductless | $12,000–$25,000 | Whole home, no ducts |
| Geothermal (ground-source) | $20,000–$45,000 | Highest efficiency, no 2026 federal credit |
Equipment + labor. Cold-climate and premium variable-speed units cost more. Confirm with local quotes.
Pro tip: weatherize first
Air-sealing and insulation lower your heat loss, which shrinks both the heat pump you need and its running cost — and it pushes the balance point colder, cutting expensive backup heat. In the calculator, switching insulation from “poor” to “good” can move a break-even result firmly into the black. See our insulation calculator to size it.
Frequently Asked Questions
Will a heat pump actually save me money?↓
It depends on what you heat with today and your local prices. Switching from propane, heating oil or electric resistance almost always saves money — often $800–$2,000/year. Switching from cheap natural gas in a cold climate with expensive electricity can cost slightly more to run. This calculator shows the honest answer for your exact fuel, prices and climate, including the electric-resistance backup heat most tools ignore.
Did the federal heat pump tax credit expire?↓
Yes. The One Big Beautiful Bill (signed July 4, 2025) ended the Section 25C energy-efficient home improvement credit — including the $2,000 heat pump credit — for anything placed in service after December 31, 2025. The Section 25D credit covering geothermal also expired the same day. If you installed in 2025 or earlier you can still claim it on Form 5695, but 2026 installs get no federal credit. The calculator defaults the federal credit to $0 for this reason.
What is the HEEHRA rebate and do I qualify?↓
HEEHRA (the Home Electrification and Appliance Rebates program) is a point-of-sale rebate of up to $8,000 toward a heat pump. Households below 80% of area median income (AMI) can get 100% of project cost up to $8,000; those at 80–150% AMI get 50% up to $8,000; above 150% AMI are not eligible. Unlike the tax credit, HEEHRA survived the 2025 law — but it is administered state-by-state and funding is limited. Several states (e.g. California single-family, Colorado Front Range) are already fully reserved, so check your state energy office before counting on it.
How does the calculator estimate my heating demand?↓
Two ways. The accurate path: enter your actual annual fuel use (therms of gas, gallons of oil/propane, or kWh) from your utility bills. The estimate path: we model delivered heat from your home size, climate zone and insulation level. Heat pump electricity is then delivered heat ÷ HSPF2, plus a climate-dependent electric-resistance backup fraction below the balance point — which is why cold climates show higher running costs unless you pick a cold-climate unit.
What is HSPF2 and what number should I use?↓
HSPF2 (Heating Seasonal Performance Factor 2) is the seasonal heating efficiency under the 2023 test standard — higher is better. Standard ducted air-source heat pumps are around 7.5–8.5; good ductless mini-splits and cold-climate units reach 9–11. A seasonal HSPF2 of 8.5 is roughly a seasonal COP of 2.5 (it delivers 2.5 units of heat per unit of electricity). SEER2 is the cooling equivalent; 15–18 is typical, premium variable-speed units hit 20+.
Do I need a cold-climate heat pump?↓
In zones 5–7 (the Northeast, Upper Midwest, Mountain West), yes — it matters a lot. A standard heat pump leans on electric-resistance backup heat (COP 1) on the coldest days, which is expensive. A cold-climate (ccASHP / variable-speed) unit holds capacity down to about 5°F and slashes that backup, raising your effective seasonal COP. Tick the cold-climate box in the calculator to see the difference.
How much does a heat pump cost to install in 2026?↓
A whole-home ducted air-source heat pump typically runs $12,000–$20,000 installed; a single-zone ductless mini-split is $4,000–$8,000, and a multi-zone ductless system $12,000–$25,000. Cold-climate and premium variable-speed equipment costs more. Geothermal (ground-source) is $20,000–$45,000 and, since the 25D credit expired, no longer carries a 30% federal credit for 2026 installs.
Does a heat pump replace both my furnace and AC?↓
Yes — a single air-source heat pump provides both heating and cooling, so it replaces your air conditioner as well as your furnace. That is why the calculator compares cooling cost at both your old AC efficiency and the new SEER2: if your old AC was inefficient, the cooling side adds to your savings too. Some cold-climate homes keep the existing furnace as a "dual-fuel" backup instead of electric resistance.
