Tule Sacramento Heat Pump: Heat Pump Installation in Sacramento, CA

3electric utilities in the metro; PG&E supplies the gas

Why the same heat pump plays out differently across the region

A ducted heat pump is a central air conditioner with a reversing valve, so one outdoor unit cools the house in July and heats it on foggy January mornings.

Around Sacramento, three things decide how that plays out. First, your electric utility: SMUD, Roseville Electric or PG&E, while PG&E supplies gas across the region.

Second, your climate zone: Title 24 puts the Placer County cities in zone 11 and most of the rest of the area in zone 12, with 1% design afternoons from 95°F in Galt to 103°F in Rocklin. Third, the house itself: its ducts, its panel and the permit office that covers the parcel.

The Sacramento homeowner's guide walks through all of it, from how the refrigerant loop works to which rebates are still open.

~$18,950SMUD's published median for gas-to-electric heat pump projects, before rebates

What a furnace-and-AC swap costs before and after SMUD

Replacing a gas furnace and central air conditioner with one ducted heat pump has a public benchmark here: SMUD's running median for gas-to-electric heat pump projects in its rebate program is about $18,950 before rebates.

The total moves with what the house needs beyond the equipment. In local program data, conversions without panel or duct work had a lower median, near $16,800, while a 100- to 200-amp panel upgrade typically adds $1,500 to $4,500.

On a qualifying system, SMUD's $3,000 rebate for variable-stage equipment, or $2,000 for two-stage, then comes off the total, and its Go Electric rebates may offset part of the panel and circuit work. Capping the gas line and removing or reusing the furnace cabinet are part of the scope.

The conversion cost breakdown shows where each part of the price goes.

~$17,000SMUD's published median for electric-to-heat-pump upgrades, split systems

Replacing a heat pump that is already there

If the house already heats with electricity, whether through an older heat pump or electric resistance heat, there is no gas line to cap and no furnace to take out, and SMUD tracks those jobs as a separate category.

Its published median for electric-to-heat-pump upgrades is about $17,000 for split systems and about $19,000 for package units, before rebates. Individual projects run far wider: SMUD's program figures stretch from about $9,000 to nearly $45,000, which is why this site gives a midpoint rather than a band.

What moves a replacement price includes whether the air handler and line set suit the newer A2L refrigerants, whether the ducts pass their test, and the compressor tier. SMUD pays $1,000 on a qualifying two- or variable-stage electric-to-electric upgrade. The replacement cost guide lays out each driver.

R-8minimum insulation on new ducts for SMUD's rebate

How SMUD's heat pump money actually reaches you

SMUD's heat pump rebate is not something a homeowner files alone.

A participating contractor in the SMUD Contractor Network submits it, and may apply it upfront on the invoice. The paperwork follows the code: the job needs its permit and inspections, a passing Title 24 result recorded on the CF3R form, any new ductwork insulated to at least R-8, and a Wi-Fi, seven-day programmable connected thermostat.

The home needs an active SMUD account on its own SMUD meter, single-stage equipment does not qualify, and Efficiency First California may carry out a field quality check afterward. Money is subject to funding, and SMUD says its rebate can be combined with other incentives where any apply. Rebate-qualified installations are available on request.

The SMUD rebate walkthrough covers each requirement and the Go Electric add-ons.

Nov 14, 2025last day to reserve TECH Clean California incentives

What closed outside SMUD, and what is left

Most of the statewide and federal money that once stacked on a heat pump is gone.

TECH Clean California took its last reservations on November 14, 2025. The federal HEEHRA rebates, worth up to $8,000 for income-qualified households, are fully reserved in California, and the Energy Commission says a second phase will be announced later.

The federal 25C tax credit covered qualifying heat pumps placed in service through the end of 2025 and does not apply after that.

Outside SMUD, Roseville Electric lists no residential heat pump rebate and no single-family PG&E heat pump rebate is on record, so a budget in Roseville, Davis or Rocklin should assume no utility rebate. The Energy Commission also warns about scams offering federal heat pump rebates. The statewide incentive guide records each program's status.

14days a year at 100°F or hotter, Sacramento Executive Airport (NOAA normals)

Cooling through 100-degree afternoons

A heat pump cools the same way a central air conditioner does, so the July question is capacity and airflow, not the technology.

NOAA's normals for Sacramento Executive Airport count about 76 days a year at 90°F or hotter and 14 at 100°F or hotter, and the heat is dry: the July mean dew point is about 54°F, so nearly all the load is temperature rather than humidity. That shapes what matters.

Cooling capacity drops as the outdoor air gets hotter, attic ducts pick up heat on the way to the rooms, and SMUD's highest summer price falls on weekdays from 5 to 8 p.m., late in the hot part of the day.

A variable-speed unit that pre-cools and then runs slowly through the evening fits that pattern. The summer performance guide explains rated capacity at high temperatures.

25%largest size increase on the City of Sacramento's standard change-out permit

Getting the size right, and the 25% limit

Capacity should come from a room-by-room load calculation at your town's design conditions, not from the tonnage on the old condenser.

Design afternoons run from 97°F in Davis to 103°F in Rocklin at the 1% level, and new windows, insulation or an addition change the load too. Oversizing has a cost: a system that is too big short-cycles in spring and fall and leaves the far rooms uneven. Title 24 limits it.

Unless airflow is verified at 350 cfm per ton or more, a replacement heat pump may exceed the cooling load by only about 6,000 Btu per hour.

The City of Sacramento's standard web permit also keeps the new unit within 25% of the old one's size; 1,682 of the 1,950 heat pump permits it issued from October 26, 2025 to October 25, 2026 carried that condition. The sizing guide shows how a load is built up.

0.0-0.2nights a year at or below 20°F at Sacramento's airport stations (NOAA normals)

Backup heat strips, and when they should run

A ducted heat pump's air handler can hold electric heat strips as backup.

On the valley floor they are rarely needed for capacity: NOAA's normals show 0.0 to 0.2 nights a year at or below 20°F at the Sacramento airport stations, and the airport's 0.2% heating design is 31°F.

Where strips earn their place is during a defrost cycle, when the unit briefly runs in cooling mode and the strips keep the supply air from turning cool.

The risk is in the controls: a thermostat that brings the strips on every time the setting jumps a few degrees can push winter bills up without anyone noticing. Title 24 also limits electric resistance as the primary heat in a replacement system, and strips add electrical load that can decide the panel question.

The backup heat and defrost guide explains lockout settings and what an aux heat indicator means.

$0.1285SMUD winter off-peak price per kWh

What the electric bill looks like by season

Switching to a heat pump moves heating onto the electric bill, so the rate plan matters as much as the equipment.

SMUD's standard Time-of-Day rate charges $0.1285 per kWh off-peak in winter and $0.3765 at the weekday 5 to 8 p.m. summer peak, plus a $27 monthly fixed charge.

PG&E's E-ELEC plan, open to homes that use an electric heat pump as their main heating and cooling, charges about 28 to 32 cents per kWh in winter, with its peak from 4 to 9 p.m. every day. Roseville Electric has no residential time-of-use schedule; its second tier starts above 500 kWh a month.

In practice that means pre-cooling before the peak, a setback schedule the heat pump can recover from without strips, and checking whether another plan suits the new load. The electric bill guide runs the numbers by utility.

2.9therms a day used by PG&E-gas, SMUD-electric homes in a peak February week (CEC 2019 survey)

Retiring the furnace: what changes besides the fuel

Gas across the region comes from PG&E, at a residential baseline rate near $2.54 per therm, and winter is when that bill peaks: in the Energy Commission's 2019 appliance survey, homes with PG&E gas and SMUD electricity averaged 2.9 therms a day in the coldest February week.

Retiring the furnace removes that heating bill along with the burner, flue and gas valve, and the combustion checks they need. The air feels different too.

A furnace sends air above 100°F in short bursts, while a heat pump sends milder air for longer, which heats the house as well but feels cooler at the register.

The running-cost comparison turns on your electric rate, and on PG&E's default E-TOU-C plan a heat pump has to average a COP of about 4 to beat a 95% furnace. The furnace comparison sets the two side by side.

89%SMUD households with central air conditioning (CEC 2019 survey)

Ducts or no ducts

Most homes in SMUD territory already have a duct system: in the Energy Commission's 2019 survey, about 89% of SMUD households had central air conditioning, against 51% in PG&E's territory.

For those houses a ducted heat pump works through the existing ducts, with one indoor air handler or furnace coil and one outdoor unit, so nothing new goes on the walls of each room. Ductless mini splits put a head in each room and suit additions, converted garages or houses that never had ducts.

They are a separate trade and are not offered through this site. For a ducted system, the deciding question is whether the existing ducts can carry heat pump airflow once they have been tested and sealed. The ducted and ductless comparison sets out the comfort, cost and layout tradeoffs.

$200SB 222 permit fee cap for a residential heat pump HVAC system

Permits, the ECC-Rater and SB 222

California treats a heat pump change-out as an alteration, so the permit brings a set of checks with it.

The installer seals the connected ducts and an ECC-Rater tests them against a target of 10% total leakage or 7% leakage to the outside, with a tighter 6% where the system sits in a garage. Refrigerant charge is verified for heat pumps in every climate zone, with at least 300 cfm of airflow per ton.

City of Sacramento change-out inspections also look for working carbon monoxide and smoke alarms.

State law is set to simplify the process: SB 222 caps the permit fee for a residential heat pump HVAC system at $200 unless a city or county adopts written findings, and requires automated online permitting for licensed contractors by July 1, 2028. Ask the permit office whether the cap applies yet.

The permit and Title 24 guide goes office by office.

719City of Sacramento permit descriptions mentioning a panel, Jan 1 to Oct 25, 2026

Panels, circuits and the 125-amp detail

Whether a heat pump needs electrical work depends on its backup heat and on what the panel already carries.

The City of Davis's service-load worksheet counts a heat pump's nameplate load in full, which shows how quickly a heat pump and an EV charger can fill an older 100-amp service.

City of Sacramento permits show how often the two kinds of work travel together: 719 permit descriptions from January 1 to October 25, 2026 mention a main service panel or a panel upgrade. Two SMUD details are worth knowing before an upgrade.

Go Electric pays toward a panel, subpanel or new circuits only on gas-to-electric projects, and SMUD's Low Use rate, with its lower fixed charge, is limited to panels of 125 amps or smaller and low monthly use. A panel upgrade also takes its own electrical permit.

The panel and circuit guide covers load calculations and costs.

2045City of Sacramento goal for all-electric existing buildings

Is anyone requiring you to give up gas?

Nothing the City of Sacramento has adopted requires an existing home to replace a working gas furnace.

Its Existing Building Electrification Strategy, adopted in May 2024, sets a goal of all-electric existing buildings by 2045, and the City's own FAQ says it will not set mandatory requirements for immediate appliance replacement.

The state's heat pump baseline in Title 24 applies to new construction, where homes are designed around heat pumps and a gas furnace is possible only through the code's performance path. State law also pushes the other way for existing homes: SB 222 voids HOA rules that would block a gas-to-electric replacement.

In practice the furnace's age and your electric utility, not a deadline, set the timing for most households. The guide to California's gas furnace rules tracks which rules are adopted and which are only proposals.

10%SMUD households with a heat pump in the CEC's 2019 survey

A heat pump in place of a new air conditioner

A heat pump and a central air conditioner cool identically; the heat pump adds a reversing valve so the same outdoor unit can also heat.

That makes the comparison mostly about winter and money. In the Energy Commission's 2019 survey about 10% of SMUD households had a heat pump, against 89% with central air, so for many homes the AC replacement is the first chance to make the switch.

A new AC leaves the gas furnace doing all the heating and earns no SMUD heat pump rebate. A heat pump costs more than a like-for-like AC but takes over most or all of the heating, and at SMUD's winter rates it can heat for less than gas at modest efficiency.

Either way the outdoor unit needs a matched indoor coil, a permit and Title 24 testing. The AC comparison guide compares the two over the life of the system.

13%SMUD households with an evaporative cooler (CEC 2019 survey)

Moving on from an evaporative cooler

Evaporative coolers work in Sacramento because summer air is dry: the July mean dew point at the airport is about 54°F, and about 13% of SMUD households had one in the Energy Commission's 2019 survey.

Their limit is physics. A cooler cannot bring air below the outdoor wet-bulb temperature, which is 70°F on a 98°F design afternoon in the CEC's data, so its supply air stays well above what a refrigerated system delivers. It also cools by pulling outdoor air through wet pads, which brings wildfire smoke in with it.

A heat pump recirculates and filters indoor air and heats in winter. The catch is ducts: if the cooler feeds a single ceiling outlet or its own duct, the heat pump needs ducts sized for its airflow, so the existing furnace ducts or new ones set the scope. The evaporative cooler comparison covers the switch.

15.2minimum SEER2 for SMUD's two-stage rebate

Reading the efficiency labels

SEER2 rates seasonal cooling efficiency and HSPF2 rates seasonal heating efficiency.

Both are measured on a matched outdoor and indoor pair, so a rating only holds when the coil or air handler is the one it was tested with.

Sacramento sizes for the summer afternoon, but the heating season is long: NOAA's normals give Sacramento Executive Airport about 2,436 heating degree days a year against 1,292 cooling degree days. HSPF2 therefore deserves as much attention as SEER2 here, especially in SMUD territory, where winter heating is where the savings over gas come from.

SMUD's rebate sets the floor at 15.2 SEER2 with a two-stage or variable-stage compressor. Ratings also assume correct charge and airflow, which is one reason Title 24 verifies both after installation. The ratings explainer shows how COP relates to both numbers.

700EPA GWP limit for refrigerant in new residential systems

The newer refrigerants, R-454B and R-32

New residential heat pumps must use a refrigerant with a global warming potential below 700 under the EPA's Technology Transitions rule, which applied to new systems from January 1, 2025.

In practice that means A2L refrigerants such as R-454B or R-32 in place of R-410A.

A2Ls are classed as mildly flammable, so some indoor equipment carries leak detection, and the indoor coil must be rated for the same refrigerant as the outdoor unit: a new outdoor unit cannot simply be paired with an old R-410A coil. Existing line sets are checked for size and cleanliness rather than reused by default.

Systems whose components were all made or imported before 2025 have no installation deadline, which matters if a quote offers older R-410A stock. The refrigerant guide explains what the change means for older systems and repairs.

Where the outdoor unit goes, and how loud it is

The City of Sacramento's standard change-out permit assumes the new outdoor unit goes where the old condenser sat and is no more than 25% larger.

Moving it, say away from a bedroom window or a neighbor's patio, takes the job off that simple path, and in Roseville a new unit in the attic or on the roof needs stamped plans.

Location also affects how well the unit runs: the coil needs the open space around it that the manufacturer specifies, and the pad has to shed defrost water away from the foundation so it does not refreeze underneath. Sound depends on the installation as much as the brand.

A level pad, vibration isolation, a line set that does not touch the framing and a variable-speed compressor that runs slowly most of the time all help. The placement guide covers clearances and quieter options.

From the permit to the final inspection

A change-out follows a fixed order.

The load calculation, duct test and panel check come first, because they decide the equipment. The permit is pulled before work starts: in the City of Sacramento it is an online minor permit, and in unincorporated Sacramento County a residential heating and cooling permit issues automatically once it is paid.

On installation day the old refrigerant is recovered, the outdoor unit and the air handler or coil are set, and the lines are brazed, pressure-tested and evacuated before charging. Commissioning checks airflow, charge, defrost and any backup heat, and the thermostat is set up.

Then the ECC-Rater verifies the ducts and charge, and the inspector signs off. SB 222 requires cities and counties to offer asynchronous inspections from July 1, 2027. The step-by-step installation guide covers what to expect at each stage.

3bids SMUD advises getting before choosing

Lining up bids side by side

SMUD advises getting at least three bids, and bids are only comparable when they describe the same job.

A complete one names the outdoor unit and the indoor coil or air handler as a rated match, the compressor type (single-stage, two-stage or variable-speed) and the SEER2 and HSPF2 ratings. It says whether a load calculation was done, what duct sealing or replacement is included and what happens if the duct test fails.

It lists the electrical work, the permit, the ECC-Rater verification and who files any SMUD rebate paperwork. SMUD's published median for gas-to-electric projects, about $18,950 before rebates, is a useful check on a bid that looks far too high or too low for its scope.

The quote comparison checklist lists the questions to ask each bidder.

Smoke season and indoor air

When wildfire smoke settles over the valley, a ducted heat pump helps mainly because it recirculates indoor air through a filter rather than pulling outdoor air in, as an evaporative cooler does.

How much it helps depends on the filter and the ducts. A denser filter catches finer smoke particles but resists airflow, and a heat pump already needs more airflow than a furnace, so the return and filter slot have to be sized for it or the system loses capacity.

Running the fan continuously on smoke days moves more air through the filter. Leaky return ducts in the attic or garage can draw unfiltered air in, which Title 24 duct sealing reduces. SMUD lists filtration among the factors that change a project's installed cost. The smoke and filtration guide covers filter ratings and fan settings.

How long the system lasts, and what shortens it

No heat pump comes with a guaranteed service life, and in Sacramento one outdoor unit works both seasons, so it builds run hours faster than an air conditioner that rests all winter.

Much of what shortens that life can be avoided. An oversized system short-cycles, adding starts and wear. A wrong refrigerant charge or starved airflow makes the compressor work harder, which is why Title 24 verifies both on every change-out.

Clogged filters, a coil boxed in by plants or fences, and a blocked condensate drain wear on it over time. Two-stage and variable-speed compressors that run slowly most of the time start and stop less often. When the time comes, replacing an older heat pump with a qualifying system earns SMUD's $1,000 electric-to-electric rebate.

The lifespan guide covers maintenance and when replacement beats repair.
