What the job involves
A heat pump looks like an air conditioner outside but runs in reverse in winter to heat the home. Heat pump replacement in Stockton is either a like-for-like swap or a switch from a gas furnace and AC to a heat pump with an electric air handler.
A switch can change the electrical load. The installer may need a new circuit, and sometimes a panel upgrade. The gas line to the old furnace is capped. Under the 2025 Energy Code, in effect for permits applied for on or after January 1, 2026, heat pumps are the baseline the state uses for many new systems.
Why Stockton’s climate suits heat pumps
Stockton’s winter design temperature is 30°F, according to NOAA engineering data. The area logs about 2,963 heating degree days a year against 1,703 cooling degree days (base 65°F). That’s a heating load most heat pumps can carry, though the contractor should still size it from a load calculation.
Rebates and tax credits in 2026
Rebates for heat pumps are thinner in 2026 than they were in 2024 and 2025. The IRS allows the federal Energy Efficient Home Improvement Credit only for property placed in service before the end of 2025. TECH Clean California says its single-family heat pump incentives have been reserved statewide since November 14, 2025. The TECH incentive updates page says HEEHRA single-family rebates were fully reserved statewide as of February 24, 2026.
Ask the contractor which incentives, if any, still apply to your home on the day you sign. Don’t sign a price that depends on a rebate nobody has confirmed.
What affects the price
Angi’s 2026 data lists air-source heat pumps at $4,500 to $8,000 nationally, and ductless mini-splits from $2,000 to $14,500. Electrical upgrades, the air handler and duct changes add to that. See the cost guide.
Local factors
| Local factor | What applies in Stockton | How it affects the job or price |
|---|---|---|
| City permit | Stockton requires a permit for an HVAC changeout, a furnace, coil or condenser swap, or more than 25 feet of new or replaced ducting (BLDG-0048) | Permit fees and the registered energy forms are part of the price; ask that both appear on the quote |
| Heat pump efficiency minimum | Split heat pumps must meet at least 14.3 SEER2 and 7.5 HSPF2 (DOE) | Sets the lowest-cost equipment that can legally be installed |
| Winter design point | 99.6% heating design temperature of 30°F at Stockton Metro Airport (NOAA) | Mild winters let a standard heat pump carry most homes without large backup heat |
| State rebates | TECH and HEEHRA single-family incentives are reserved statewide (TECH Clean California) | Budget without them unless a contractor confirms a reservation in writing |
| Federal tax credit | The 25C credit covers property placed in service before the end of 2025 (IRS) | A 2026 install can’t claim it; ignore quotes that still subtract it |
Common local situations
Many Stockton homes pair a gas furnace with central AC. Replacing both at once with a heat pump avoids buying two pieces of equipment. If your furnace is newer than your AC, a contractor may suggest a dual-fuel setup that keeps the furnace as backup. Ask for prices for both options.
Questions to ask a contractor
- What are the unit’s SEER2 and HSPF2 ratings?
- Does my electrical panel have room, and is any upgrade priced in?
- Which refrigerant does it use?
- Does the quote assume any rebate, and has it been reserved?
What to mention when you call
Tell us whether you have a heat pump now or a gas furnace with AC, the age of the electrical panel if you know it, and whether you’re interested in ductless units for rooms the ducts don’t reach.
