Replacing a furnace in Silverdale, WA
A furnace usually tells you it is near the end before it quits: repairs get more frequent, rooms heat unevenly, and the gas or electric bill creeps up. When that happens, our Bremerton branch comes to your Silverdale home, measures it, and lays out the replacement choices side by side with written prices. The estimate is free.
Silverdale sits at the head of Dyes Inlet in central Kitsap County, and it is not an incorporated city. Heating here runs on either Cascade Natural Gas or PSE electricity (Kitsap Economic Development Alliance, infrastructure), and that single fact drives most of the decisions below: which furnaces make sense, which rebates apply, and whether a heat pump should be part of the plan.
Furnace replacement costs
No Silverdale-only price survey exists, so these are Seattle-area figures. They are a guide, not our quote.
| Item | Seattle-area estimate |
|---|---|
| Average new furnace, installed | About $4,683 |
| Most common range | $2,762 to $6,683 |
| Natural gas furnace | $3,800 to $10,000 |
| Electric furnace | $2,000 to $7,000 |
| Labor as a share of the job | About 20 to 30 percent |

Four things change the price most on a Silverdale job:
- Efficiency. A 95 percent or better condensing gas furnace costs more than an 80 percent unit and needs PVC venting and a condensate drain, but it burns less gas every winter.
- Where the furnace sits. Garage and utility-closet installs are quicker than crawlspace or attic installs.
- Duct condition. We quote duct repairs as a separate line so you can choose.
- Venting and gas line changes when the unit moves or the vent type changes.
When to replace instead of repair
We will tell you when a repair is the smarter spend. Replacement usually makes more sense when:
- The furnace is 15 to 20 years old or older and needs a major part such as a heat exchanger, inducer or control board.
- A repair would cost a large share of a new unit’s price.
- You have had several repair calls in the last two winters.
- A crack in the heat exchanger or a carbon monoxide problem has been found. That is a safety issue, and we will shut the unit off.
- Some rooms never get warm, the blower runs loud, or the house is dusty and dry all winter.
Gas furnace, electric furnace, heat pump or dual fuel
What you have now narrows the choice:
| You have | Options we usually quote |
|---|---|
| Cascade gas furnace | A new high-efficiency gas furnace, or a dual-fuel system that pairs a heat pump with a new gas furnace |
| Electric furnace | A ducted heat pump with an electric air handler, or a new electric furnace |
| Baseboard heat, no ducts | Ductless mini-split heat pumps |
Electric furnaces are the most expensive way to heat with electricity. Swapping one for a heat pump is usually the replacement with the fastest payback, and it is the one PSE rebates most heavily.
Choosing the furnace itself
Once the fuel is settled, three features separate one furnace from the next:
- Burner stages. A single-stage furnace is on or off at full fire. A two-stage or modulating furnace runs at low fire most of the winter, which means quieter operation, steadier temperatures and fewer cold spots between cycles.
- Blower motor. A variable-speed blower moves air gently for longer, improves filtration, and pairs well with a heat pump or central AC added later.
- Efficiency (AFUE). An 80 percent furnace sends a fifth of its fuel up the flue. A 95 to 97 percent condensing furnace keeps most of that heat in the house.
Ask us to quote two options side by side: a solid standard choice and a higher-efficiency one, with the yearly running cost difference explained, so you can pick what fits your budget and how long you plan to stay.
After the install: keeping it running
A new furnace needs little, but that little matters:
- Change or clean the filter every one to three months during heating season.
- Keep the area around the furnace and the outdoor vent terminations clear; leaves and moss can block a PVC vent on a side wall.
- Test your carbon monoxide alarms twice a year.
- Book a tune-up each fall so the burners, flame sensor, drain and safeties are checked before the first cold snap.
Register the furnace with the manufacturer soon after install. Many manufacturers require registration within a set time for the full parts warranty, so check the paperwork left with the unit.
Rebates that apply in Silverdale
- Electric heat to a heat pump (PSE): $1,500, plus up to $2,400 more for income-qualified homes through Efficiency Boost (PSE electric resistance to heat pump rebate).
- Cascade Natural Gas: rebates on qualifying furnaces and dual-fuel systems installed on or after 15 March 2026 (Cascade Natural Gas residential rebates).
- PSE hybrid heat pump rebate: only for PSE gas customers, so Silverdale homes on Cascade gas do not qualify.

Sizing, venting and ducts done right
The old furnace’s size is not a good guide; many older units were oversized. We run a load calculation for the house as it is today, including any insulation, window or addition changes. We then check the ducts: static pressure, leaks at joints and the plenum, and whether the return is big enough. A new furnace on a starved return runs hot, loud and short-lived.
Venting gets the same attention. An 80 percent furnace vents through a metal flue; a condensing furnace vents through PVC to an exterior wall or roof. If an old water heater shares the flue, removing the furnace from it can leave the flue too large for the water heater alone, so we check and line it if needed.
Permits and the day of the install
Because Silverdale is unincorporated, the mechanical permit comes from Kitsap County Department of Community Development (Kitsap County DCD, residential mechanical and plumbing permit form), and any new wiring is permitted through Washington L&I. We file both.
- Before the day: we confirm the model, the permit and the arrival window.
- Removal: we protect floors, shut off gas and power, and take the old unit away.
- Install: set the furnace, connect gas, venting, power, condensate and ducts, and fit a new filter rack.
- Start-up: test gas pressure, temperature rise and combustion, check for carbon monoxide, and set the thermostat.
- Walkthrough: we show you the filter, the shutoffs and the paperwork.
Most straight swaps take one day. Heat pump or dual-fuel jobs usually take two. The county inspection is scheduled after the install.
Warranty and Home Comfort Club
We support the manufacturer’s warranty on covered equipment parts, and we stand behind our furnace installations with a 1-year labor warranty from installation.

Silverdale furnace replacement FAQ
How much does a new furnace cost in Silverdale?
Seattle-area data puts the average installed furnace at about $4,683, with most jobs between $2,762 and $6,683 (Angi, July 2026). Your written quote comes after we see the home.
Should I repair or replace my furnace?
Replace when the furnace is 15 to 20 years old and needs a major part, when repairs keep recurring, or when a cracked heat exchanger is found. Otherwise a repair is often the better spend.
Is gas in Silverdale supplied by PSE or Cascade?
Cascade Natural Gas supplies gas in Silverdale; PSE supplies electricity. That is why PSE’s hybrid heat pump rebate does not apply here.
Can I swap my electric furnace for a heat pump?
Yes. A ducted heat pump can use your existing ducts, and PSE offers a $1,500 rebate for switching from electric heat.
Who issues the furnace permit in Silverdale?
Kitsap County DCD, since Silverdale is unincorporated. We pull the permit and meet the inspector.
How long does furnace replacement take?
Usually one day for a like-for-like swap, two days for a heat pump or dual-fuel system.
What furnace efficiency should I choose?
A 95 percent or higher condensing gas furnace burns less gas each winter but needs PVC venting and a condensate drain. An 80 percent furnace costs less up front. We explain the running-cost difference so you can compare.
What warranty comes with your work?
We support the manufacturer’s warranty on covered equipment parts, and our labor warranty covers installations for 1 year from installation. Home Comfort Club members (monthly membership starting at $15 a month) with a new system installed by Home Comfort Alliance get extended labor coverage for as long as their membership stays active, up to 5 years from installation.
