How do a heat pump, a gas furnace and dual fuel compare?
A heat pump moves heat instead of making it, and the same equipment cools in summer. A gas furnace burns natural gas for heat and needs a separate AC. Dual fuel pairs a heat pump with a gas furnace that covers the coldest hours. Here's how they differ on the things that matter in a Sacramento-area house.
| Factor | Heat pump | Gas furnace | Dual fuel |
|---|---|---|---|
| How it heats | Pulls heat from outdoor air and moves it inside through a refrigerant circuit | Burns natural gas and blows the heat through the ducts | Heat pump for most hours; the furnace takes over when it's colder or cheaper to burn gas |
| Cooling | Same system cools in summer and replaces the AC | None. Needs a separate AC | The heat pump does the cooling |
| Efficiency | Natural Resources Canada (opens in new tab) puts typical air-source efficiency at 2.0 to 5.4 units of heat per unit of electricity at 46°F (8°C) | Rated by AFUE, the share of the gas's energy that becomes heat in the house | Depends on which side is running |
| Feel of the air | More air at a lower temperature, roughly 77 to 113°F per NRCan | Less air at a higher temperature, roughly 131 to 140°F per NRCan | Changes with the heat source |
| Combustion and CO | No combustion in the house (ENERGY STAR (opens in new tab)) | Burns gas, so venting and a CO alarm matter | The furnace side still burns gas |
| Bills | Electric only | PG&E gas for heat, plus electricity for the blower and the AC | Mostly electric, plus gas when the furnace runs |
| SMUD rebate (as of 2026-10-06) | $3,000 variable-stage or $2,000 two-stage for gas-to-electric; $1,000 electric-to-electric | None listed | SMUD's gas-to-electric tiers describe conversions. Confirm with SMUD before assuming a dual-fuel setup qualifies |
| Usually fits | Replacing both the AC and the furnace, especially at a SMUD address | A newer AC with a failing furnace, or when electrical upgrades aren't practical yet | A newer furnace with an aging AC, per ENERGY STAR (opens in new tab) |
Do heat pumps work in Sacramento winters?
Yes. The Department of Energy (opens in new tab) says that in moderate climates, heat pumps can be an energy-efficient alternative to furnaces and air conditioners. SMUD (opens in new tab) goes further on its rebate page: it states that new multi-stage heat pumps heat and cool extremely well in Sacramento's climate.
Two things feel different if you're used to gas. First, a heat pump delivers more air at a lower temperature, so the vents feel warm rather than hot, and the system runs longer cycles. Second, on frosty mornings the outdoor unit runs short defrost cycles, and you may see steam rising from it. Both are normal. Our guide to a heat pump that seems not to be heating explains what's normal and what isn't.
Which utility serves your city, and why does it matter?
Your electric utility decides which rebate applies and what it costs to run a heat pump. Gas is PG&E in every city below, including the SMUD cities, because SMUD, Roseville Electric and Valley Clean Energy sell electricity only. Check the electric line on your bill, not the gas line.
| City | Electric | Gas | Heat pump incentive channel |
|---|---|---|---|
| Sacramento | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Elk Grove | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Folsom | SMUD (since the 1980s, not PG&E electric) | PG&E | SMUD heat pump rebate (amounts below) |
| Rancho Cordova | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Citrus Heights | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Carmichael (unincorporated) | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Fair Oaks (unincorporated) | SMUD | PG&E | SMUD heat pump rebate (amounts below) |
| Roseville | Roseville Electric (city-owned) | PG&E | Roseville Electric's own programs, separate from SMUD. Confirm current offers with Roseville Electric (opens in new tab) |
| West Sacramento | PG&E (not SMUD, not VCE) | PG&E | TECH Clean California: reserved and waitlisted (see below) |
| Davis | Valley Clean Energy (opens in new tab) supplies; PG&E delivers | PG&E | TECH Clean California: reserved and waitlisted (see below) |
What rebates and credits apply as of October 2026?
In SMUD territory, a real rebate. Elsewhere, mostly a waitlist. We checked each program against its official page on October 6, 2026. Amounts and funding change, so confirm them again on the day you sign.
Where each program stands:
- SMUD (as of 2026-10-06). Gas-to-electric conversions pay $3,000 for a variable-stage heat pump or $2,000 for a two-stage system (15.2 SEER2 minimum). An electric-to-electric upgrade pays $1,000. Go Electric rebates for a smart panel, subpanel or new circuit add up to $4,000, but only with a gas-to-electric conversion. SMUD announced the increased levels on February 18, 2026 (opens in new tab).
- SMUD's conditions. The installer must be a participating contractor in the SMUD Contractor Network (opens in new tab), the system needs a connected thermostat, the ducts must pass Title 24 testing (HERS CF3R) or new ducts must be insulated to R-8, and the job must meet permit and inspection requirements. Ask any installer for their network status and verify it yourself. This page makes no claim about 916air's.
- Roseville Electric. A separate city-owned utility, so SMUD rebates don't apply. Check Roseville Electric's rebates page (opens in new tab) or call the utility for current heat pump offers before you count on one.
- PG&E territory (West Sacramento, and Davis through PG&E delivery). TECH Clean California (opens in new tab) single-family heat pump HVAC incentives have been reserved statewide since November 14, 2025. HEEHRA single-family rebates have been fully reserved since February 24, 2026, with new reservations put on a waitlist. Both were unchanged at our October 6, 2026 check.
- Federal 25C tax credit. Per the IRS (opens in new tab), the Energy Efficient Home Improvement Credit covered qualifying property placed in service from 2023 through 2025. A heat pump placed in service in 2026 doesn't qualify unless Congress extends the credit.

Will your ducts and electrical panel handle a heat pump?
Often yes, but check both before you sign. A ducted heat pump uses the same supply and return ducts as a furnace, and ENERGY STAR (opens in new tab) notes it can usually go in as a drop-in replacement when either the AC or the furnace needs replacing. The catch is duct condition. ENERGY STAR estimates a typical duct system loses 20 to 30 percent of the air it moves to leaks, holes and poor connections (duct sealing (opens in new tab)). A heat pump's gentler supply air makes those losses easier to feel, and SMUD's rebate requires the ducts to pass Title 24 testing anyway. A ductwork and airflow check belongs in the scope.
The panel is the other question. A heat pump, especially one with electric backup heat, may need a new circuit or more panel capacity than a gas furnace did. That's what SMUD's Go Electric rebate is for, and it's why the permit matters. Our Sacramento HVAC permit guide explains which office issues it where you live.
When does a gas furnace or dual fuel still make sense?
When the timing or the house doesn't fit a full conversion. If your AC is only a few years old and the furnace is the part that failed, replacing the furnace alone is usually the sensible move. For a like-for-like swap in the City of Sacramento, see furnace installation in Sacramento.
The reverse case is where dual fuel fits. ENERGY STAR (opens in new tab) suggests that if you have a relatively new furnace and an older AC, replacing the AC with a heat pump creates a dual-fuel system for a modest cost over a standard AC. The heat pump covers most of the heating, and the furnace stays as backup.
Gas also stays on the table when the panel work isn't practical yet, or at a PG&E-territory address where the main incentives are reserved. None of this is permanent. You can plan the heat pump for the next replacement cycle.
How do you decide for your house?
Start with the facts you can check yourself, then get a written scope that answers the rest. A good proposal names the equipment and its ratings instead of just saying "heat pump."
Work through these before you choose:
- Which electric utility is on your bill: SMUD, Roseville Electric, or PG&E (with VCE supply in Davis)
- The age and condition of both the AC and the furnace, since a heat pump replaces both
- Whether the ducts can pass a Title 24 duct test, or need sealing or replacement first
- Panel capacity, and whether a new circuit or subpanel is needed
- The rebate status on the day you sign, checked on the program's own page
- A written scope with model numbers, SEER2 and HSPF2 ratings, permit handling and HERS testing

Frequently asked questions
Is a heat pump cheaper to run than a gas furnace in Sacramento?
It depends on your electric rate, PG&E's gas rate, the equipment's efficiency, and how you set the thermostat, so no single answer fits every house. The useful comparison uses your own bills: your winter gas use against the heat pump's expected electric use on your rate plan. A written proposal should show that math, not just a promise of savings.
Will a heat pump keep my house warm on a cold morning?
A correctly sized heat pump should. The Department of Energy calls heat pumps an efficient alternative to furnaces in moderate climates, and SMUD states that new multi-stage heat pumps heat well in this climate. On frosty mornings it runs short defrost cycles, and some systems use backup heat briefly. The air feels warm rather than hot, and cycles run longer than a furnace's. Both are normal.
What is a dual-fuel system?
Dual fuel pairs an electric heat pump with a gas furnace. The heat pump heats the house most of the time and handles all the cooling. The furnace takes over when it's colder or when gas is the cheaper option. ENERGY STAR suggests it when you have a relatively new furnace and an AC that needs replacing.
Does SMUD pay a rebate for replacing a gas furnace with a heat pump?
As of October 6, 2026, yes: $3,000 for a variable-stage heat pump or $2,000 for a two-stage system in a gas-to-electric conversion, plus up to $4,000 in Go Electric rebates for panel and circuit work. The installer must be in the SMUD Contractor Network, and the job must meet SMUD's equipment, duct-testing and permit rules. Check SMUD's page for current terms.
Can I still get the federal tax credit for a heat pump?
Not for a heat pump installed in 2026, unless Congress extends the credit. The IRS says the Energy Efficient Home Improvement Credit (25C) covered qualifying property placed in service from 2023 through 2025. Utility rebates like SMUD's are a separate program and are still offered. Check the IRS page and your tax preparer if your project straddled the deadline.
