Furnace replacement in Port Orchard, WA
Home Comfort Alliance replaces gas and electric furnaces in Port Orchard homes, with installers dispatched from our Bremerton branch across the Sinclair Inlet. Every replacement starts with an in-home visit: we measure the house, check the ductwork and venting, and hand you written options with model numbers, rebates and financing on one page. Replacement estimates are free.
Port Orchard looks across Sinclair Inlet toward Bremerton, with SR 16 running along its edge. Homes here heat with a mix of fuels. Electricity comes from Puget Sound Energy, and natural gas, where the street has it, comes from Cascade Natural Gas (Kitsap Economic Development Alliance, infrastructure). That split decides which rebates apply to your new furnace, so we confirm your utility accounts before we price anything.
In short: if your furnace is past about 15 years old, needs a costly repair, or can’t keep the house even, replacement usually beats another repair. We will also show you whether a heat pump or a dual-fuel system would cost less to run than a straight furnace swap.
What a new furnace costs
Prices below are a regional estimate from Seattle-area data, since no Port Orchard-specific survey exists. Your written quote replaces them once we see the house.
| Furnace type | Typical installed cost (Seattle area) |
|---|---|
| Average new furnace | About $4,683 |
| Common range | $2,762 to $6,683 |
| Natural gas furnace | $3,800 to $10,000 |
| Electric furnace | $2,000 to $7,000 |
| Labor share of the project | About 20% to 30% |

What moves the number on a Port Orchard job:
- Efficiency. A 95% or higher condensing gas furnace costs more up front than an 80% model and needs PVC venting and a condensate drain.
- Location. Crawlspace and attic installs take longer than a garage or basement closet.
- Ductwork. Undersized or leaky ducts can undo a new furnace; we price repairs as a separate line so you can decide.
- Gas line and venting changes. Moving the unit or switching vent types adds labor and permit work.
- Add-ons. Pairing the furnace with a heat pump or central AC, or adding filtration, is priced as an option, not bundled in.
Signs your furnace is ready to retire
- It is 15 to 20 years old and the heat exchanger or control board is failing.
- A single repair quote runs toward a third or more of the cost of a new unit.
- Rooms at the far end of the house stay cold while the furnace runs constantly.
- Your gas or electric bill climbs winter after winter with the same thermostat settings.
- You hear rumbling, banging or squealing at start-up, or see yellow flames on a gas burner.
- A carbon monoxide alarm has sounded. Leave the house, call 911 and your gas utility first, then call us.
If the furnace is younger and the problem is a single part, we will tell you so. See our Port Orchard heating repair page for repair options.
Gas furnace, electric furnace or heat pump?
| Option | Best fit in Port Orchard | Worth knowing |
|---|---|---|
| High-efficiency gas furnace | Homes already on Cascade natural gas with good ductwork | May qualify for Cascade rebates; add central AC or a heat pump for cooling |
| Electric furnace | Homes with no gas service and a tight budget | Lowest install cost, but electric resistance heat is the costliest to run |
| Ducted heat pump | Electric furnace homes on PSE power | Heats and cools; PSE rebates apply when replacing electric resistance heat |
| Dual-fuel (heat pump plus gas furnace) | Gas homes that want cooling and lower bills | Heat pump carries most of the year, furnace takes the coldest hours |
Electric furnace owners often look at heat pumps, because the same ducts can carry heated and cooled air. Read more on our Port Orchard heat pump installation page.
Rebates for Port Orchard furnace replacements
Rebates depend on which utility serves the home. As of September 2026:
- Cascade Natural Gas customers: Cascade lists Washington rebates for qualifying high-efficiency gas furnaces and dual-fuel systems installed on or after March 15, 2026, where gas stays the primary heat (Cascade Natural Gas residential rebates). Amounts are set by Cascade, so we check them against your model before you sign.
- Electric furnace homes on PSE power: switching an electric furnace to a qualifying heat pump can earn PSE’s electric resistance to heat pump rebate of $1,500, with up to $2,400 more through Efficiency Boost for qualifying households (PSE electric resistance to heat pump rebate).
- PSE gas programs: PSE’s hybrid and gas conversion rebates are for PSE natural gas customers, so they do not apply to Cascade gas homes in Port Orchard.
Home Comfort Alliance is a PSE Trade Ally approved contractor for HVAC systems, and PSE heating rebates require a Trade Ally or registered installer. We fill in the rebate paperwork with you at install. The federal 25C tax credit ended on December 31, 2025, so we don’t count it in any estimate.

Sizing, venting and ductwork
A furnace that is too big short-cycles, wears out sooner and leaves rooms uneven; one that is too small runs nonstop on the coldest nights. We size the new unit with a room-by-room load calculation instead of copying the old nameplate, because many homes have had windows, insulation or additions changed since the original furnace went in.
Venting matters as much as size. An 80% gas furnace vents hot exhaust through a metal flue, while a condensing furnace vents cool exhaust through PVC and drains water, so the pipe route and the drain location are planned before install day. We also static-pressure test the ductwork. If a return is starving the system, fixing it is often the cheapest comfort upgrade in the whole project.
Permits and install day
Inside city limits, the City of Port Orchard issues residential mechanical permits for furnace replacement (City of Port Orchard, residential plumbing and mechanical permits). Homes in unincorporated South Kitsap are permitted through Kitsap County instead, and any new circuit is permitted through Washington L&I (L&I, cities that do their own electrical permits). We pull the right permit and schedule the inspection.
- Estimate visit: measurements, duct check, written options.
- Scheduling: most straight replacements take one day; relocations or dual-fuel systems can take two.
- Install: floor protection, removal and disposal of the old furnace, new unit, venting, gas and electrical connections.
- Start-up: combustion and temperature checks, thermostat setup and a walk-through of filter changes.
- Inspection: we meet the inspector and close out the permit.
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.
Join our Home Comfort Club, a monthly membership starting at $15 a month, and a new system we install gets extended labor coverage for as long as your membership stays active, up to 5 years from installation. Ask your technician or comfort advisor for the current plan details.
Port Orchard furnace replacement FAQ
How much does furnace replacement cost in Port Orchard?
Seattle-area data puts a new furnace at about $4,683 on average, with most installs between $2,762 and $6,683 (Angi, July 2026). Gas furnaces run higher than electric ones. Your written estimate from our in-home visit is free and lists the exact model and price.
Should I replace my furnace or repair it?
If the furnace is under about 12 years old and the repair is a single part, repair usually makes sense. If it is 15 or more years old, needs a heat exchanger or control board, or the repair quote is a large share of a new unit, replacement is usually the better value. We price both so you can compare.
Do Port Orchard homes use PSE or Cascade for gas?
Electric service in Port Orchard is from Puget Sound Energy. Natural gas, where available, is from Cascade Natural Gas. That is why PSE’s gas-only rebates don’t apply to most Port Orchard gas furnaces, while Cascade’s rebates may.
Can I replace my electric furnace with a heat pump?
Yes, and it is one of the most common upgrades we quote. A ducted heat pump can often use your existing ducts, adds air conditioning, and may qualify for PSE’s electric resistance to heat pump rebate because Home Comfort Alliance is a PSE Trade Ally contractor.
Do I need a permit to replace a furnace in Port Orchard?
Yes. The City of Port Orchard issues residential mechanical permits inside city limits, and Kitsap County handles unincorporated addresses. We pull the permit and meet the inspector.
How long does a furnace replacement take?
Most like-for-like replacements are finished in one day. Moving the furnace, changing venting or adding a heat pump can stretch the job to two days.
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.
