Heat pump cost in California
Gas still wins on running cost in California, by about $966 a year. For 2,000 sq ft we estimate $2,318 a year with a minimum-efficiency heat pump versus $1,353 for a gas furnace plus central AC.
Yearly running cost in California
| Heat pump heat, 7.5 / 9.5 HSPF2 | $1,976 / $1,560 |
| Heat pump cooling, 14.3 SEER2 | $342 |
| Furnace, 95% / 80% AFUE | $1,010 / $1,200 |
| AC at 14.3 SEER2 (Southwest min) | $342 |
| Heat pump vs furnace + AC | $2,318 vs $1,353 |
The heat pump costs about $966 a year more to run, so it has to win on purchase price, e.g. when the AC is due anyway.
33.25¢/kWh (EIA, July 2026 YTD); gas $2.15/therm (EIA 2025, $22.01/Mcf at 1,022 Btu/ft³). Energy only; estimates.
Installed cost (estimate)
We have no state-level installation data, so these are national estimates: about $10,000–$20,000+ installed for a 2,000 sq ft air-source system. Given California's mixed climate, start with the 16–17 SEER2 / 8–9 HSPF2 tier, which HomeGuide prices at $8,000–$15,000+.

Climate and sizing
California averages 2,814 heating degree days (40th of 48) and 929 cooling degree days (NOAA, 1991–2020). In practice, both seasons matter, which suits a heat pump that replaces furnace and AC at once. Dec's implied mean, roughly 48°F (degree-day approximation), is within what most modern heat pumps handle with little backup heat.
Heating and cooling loads are comparable; have a Manual J check both, and consider a variable-speed unit.

Questions
How much is a heat pump in California?
About $10,000–$20,000+ for 2,000 sq ft (national estimate, HomeGuide). Get three local bids.
What electricity price makes a heat pump beat gas in California?
About 17.0¢/kWh for a 7.5 HSPF2 heat pump against a 95% furnace at $2.15/therm; prices would need to fall about 16.2¢ from California's 33.25¢ average. A 9.5 HSPF2 unit would heat for $1,560 a year.
Is there a federal heat pump tax credit in 2026?
Not for 2026 installs. The federal 25C credit (30%, up to $2,000/yr for qualifying heat pumps) covered property placed in service from 2023 through December 31, 2025; 2025 installs also needed the manufacturer's QMID on the return. Source: IRS: Energy Efficient Home Improvement Credit.
