How island homes heat, and what to do next
Bainbridge Island has no natural gas utility: Puget Sound Energy lists Kitsap County as electric-only service, and Cascade Natural Gas does not list the island among its communities. Island furnaces run on electricity, propane or heating oil.

Replacing your heating system: cost, rebates and financing
Your price depends on your home's heating and cooling needs, the add-ons you need, how many rooms the system serves and where it's installed. Get a price range in about 30 seconds with our free instant quote tool, then a technician confirms the exact price on a free site visit. For a regional benchmark, Angi lists Seattle-area heat pump installs at about $6,667 to $13,852, averaging $10,218 (updated July 8, 2026, Angi); that is not our price.
Rebates on the island come from PSE only: $1,500 to replace electric resistance heat with a heat pump, $1,500 to upgrade an out-of-warranty ducted all-electric heat pump, each with up to $2,400 more through Efficiency Boost, and $300, $400 or $600 instant discounts on qualifying units. PSE's enhanced Bainbridge Island rebates ended December 31, 2025 (PSE Bainbridge update), and the federal 25C tax credit ended for equipment installed after December 31, 2025. We are a PSE Trade Ally and handle the rebate paperwork for you.
Financing through Salal Credit Union or Synchrony starts at $179/month* (financing).
*Financing through Salal Credit Union or Synchrony, subject to credit approval. Rates, terms and monthly payments depend on the amount financed, the plan and your credit. 0% interest options are available to qualifying customers. See lender for full terms.

Install day and the outdoor unit
- Free in-home visit and an ACCA Manual J load calculation.
- Written options, prices and the rebates each one qualifies for.
- A site plan showing where the outdoor unit goes, and the City mechanical and L&I electrical permits.
- Installation, start-up and a thermostat walkthrough. Most furnace installations take between 4 and 10 hours.
- City inspection and first-year maintenance included.
The City asks that permit site plans show mechanical equipment and all required setbacks, and the island zoning code lists no setback allowance for outdoor heat pump units (BIMC 18.12), so we place units outside required setbacks and buffers. Washington's noise rule limits residential equipment to 55 dBA at a neighbor's property, 45 dBA at night (WAC 173-60-040). New installations come with a 3-year Comfort Shield labor warranty on new installations, kept active with yearly maintenance. First-year maintenance is included.
Permits on Bainbridge Island
The City of Bainbridge Island issues permits island-wide and requires a mechanical permit when heat pumps or other heating systems, or LPG tanks, are added, altered or replaced (City permit information). Electrical permits come from Washington L&I. We pull the required permits for every installation.
A recent Bainbridge Island heating call: a thermostat error after a neighbor's visit
In September a Bainbridge Island homeowner called because their thermostat was showing a "max torque exceeded" message; a neighbor had changed the temperature and the furnace had come back on but was not running right.
Our technician checked the filter, inspected the blower motor and wheel (drawing 0.98 amps), brushed out the condensate trap and tested the condensate pump. With supply voltage normal and air coming off the furnace at 105°F against 70°F return air, he reset the thermostat and left the system running.
From our September 2026 service records; customer details are kept private.

Bainbridge Island heating FAQ
What heating systems do you service on Bainbridge Island?
Electric, propane and oil furnaces, heat pumps, ductless mini-splits and dual fuel systems, repaired, maintained and replaced. We also service boilers; we do not install new boilers.
Is there natural gas on Bainbridge Island?
No. PSE lists Kitsap County as electric-only service and Cascade Natural Gas does not list the island, so homes heat with electricity, propane, oil or heat pumps.
What heating rebates are available on Bainbridge Island in 2026?
PSE's standard programs: $1,500 to replace electric heat with a heat pump, $1,500 to upgrade an out-of-warranty ducted all-electric heat pump, each with up to $2,400 more through Efficiency Boost, and $300 to $600 instant discounts on qualifying units (as of October 2026). The enhanced Bainbridge rebates ended December 31, 2025.
Does PSE give a rebate to switch from oil or propane to a heat pump?
PSE's $1,500 conversion rebate is for homes heated by PSE electric resistance heat. Oil and propane homes can still get PSE's instant discount on a qualifying heat pump.
Do heat pumps work in island winters?
Yes. Island winters are mild and damp; the 2021 Seattle Energy Code lists 29°F as the winter design temperature for nearby Bremerton, well within what cold-climate heat pumps handle. A propane or oil furnace can stay as backup.
How much does a furnace or heat pump tune-up cost?
$230 per piece of equipment, or $180 for Home Comfort Club members. An oil furnace tune-up is $336 ($288 Club).
Where can the outdoor heat pump unit go?
Outside required setbacks and buffers, shown on the City permit site plan. State noise rules limit residential equipment to 55 dBA at the neighbor's property, 45 dBA at night.
Do I need a permit to replace my heating system?
Yes. The City of Bainbridge Island requires a mechanical permit to add, alter or replace heating equipment, and electrical permits come from Washington L&I. We pull the required permits.
Do you remove oil tanks?
No. If you convert from oil, you hire a certified tank decommissioner for the tank; we handle the heating system.
Do you offer after-hours heating service?
Our phones are answered and bookings are accepted 24/7. Heating and cooling technicians work during business hours and are available after hours for qualifying emergencies ($330 after-hours fee).
What warranty comes with a new system?
3-year Comfort Shield labor warranty on new installations, kept active with yearly maintenance. First-year maintenance is included. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation.
