What a heat pump costs in the Bay Area: our real price ranges
Our installed price ranges as of November 2026, what is and isn't in them, and real projects at each scope.
The short answer
As of November 2026, most 3rdGen heat pump installs in the East Bay and Marin fall between $20,000 for a ducted system on usable existing ducts and $40,000–$80,000 or more for whole-home systems that mix ducted and ductless equipment. A single ADU system usually runs $10k–$15k. These are installed prices for our own projects, not national averages, and every number below comes from jobs we have designed and built.
Price ranges by scope
Installed price for 3rdGen projects, as of November 2026, before rebates.
| Scope | Typical range | What drives it |
|---|---|---|
| Ducted heat pump, existing ducts usable | $20k–$30k | Equipment tier, capacity, controls, condenser location and access |
| Ducted heat pump + duct repair or resizing | $25k–$45k | Amount of ductwork replaced, crawlspace or attic access, return-air changes |
| Ductless multi-zone, 3–4 indoor units | $25k–$40k | |
| Whole-home ducted + ductless combination | $40k–$80k+ | Multiple systems, zoning, ductwork, filtration, ventilation and architectural coordination |
| New construction system | $20k–$50k+ | Building size, system count, Title 24/design requirements and coordination with the build |
| ADU system | $10k–$15k | Zone count, head type, line-set routing, and whether the ADU shares the main house or stands alone |
| Electrical panel upgrade, when required | $10k+ | Service size, meter location, utility requirements and site conditions |
What the ranges include
- A room-by-room Manual J load calculation, and equipment sized to it
- The heat pump equipment, indoor units and controls
- Refrigerant piping, condensate and control wiring
- Duct connections, plenums and distribution for the scope in the range
- Pressure test, evacuation, startup and commissioning
What is priced separately
- Electrical panel or service upgrades (see the table above)
- Asbestos testing and abatement, which is common in older Bay Area duct systems
- Permit scope beyond a standard mechanical permit, such as Title 24 HERS testing when the job triggers it
- Structural, finish or remodel work by the general contractor
What moves the price
Ducts
Reusing sound, correctly sized ducts is the cheapest path. Leaky, undersized or asbestos-wrapped ducts move a job up a row in the table.
Access and routing
Tight attics, crawlspaces, plaster walls, hillside lots and long line-set runs all add labor. So does hiding equipment in ceilings or behind architectural grilles.
Number of zones
Each indoor unit adds equipment, piping, a condensate path and a control. Matching each unit to its room costs more than one big unit, and it is usually why the house ends up comfortable.
Electrical
Most installs need a dedicated 240V circuit. Older 60 or 100 amp panels, or a panel already carrying solar, can mean a panel upgrade.
Ventilation and filtration
An ERV for fresh air or MERV 16 filtration for wildfire smoke is extra equipment and duct work, but it is far cheaper to add during the install than afterward.
Rebates lower the net cost
Utility, city and Air District programs can take a few thousand dollars off, and some wood-stove replacement programs pay much more. Most need approval before work starts, so check them before you sign. Our rebates page lists the current Bay Area programs and their deadlines.
Real projects at each scope
These are 3rdGen jobs that show what each kind of scope looks like. Every house prices differently, so use them for scope, not as a quote.
Ducted on existing ducts
Ducted with new duct work
- Hazel Ln, Piedmont: asbestos abated, new duct system and a 3-ton ducted heat pump
- Kensington: two ducted heat pumps in a crawlspace with new duct runs
Ductless multi-zone
- Madera Ave, Oakland: four ceiling cassettes upstairs and a wall unit downstairs
- Pacific Ave, Piedmont: four indoor units sized room by room on one outdoor unit
Whole-home, mixed systems
- Virginia St, Berkeley: three floors on one Smart Multi system, with an ERV and MERV 16
- Capistrano Ave, Berkeley: five zones of three indoor-unit types on one outdoor unit
How we get to your number
We start with a site visit and a Manual J load calculation for your house, then price the scope that calculation calls for. The estimate lists the equipment, the duct and electrical work and anything priced separately, so you can compare it line by line.
