Furnace replacement in Puyallup: what to know first
Replace a Puyallup furnace when it is past about 15 to 20 years old, needs a major repair such as a heat exchanger or gas valve, or no longer keeps the house even. Before choosing a like-for-like gas furnace, compare a heat pump or dual-fuel system, which also cools and can qualify for PSE rebates that a gas furnace alone does not.
Puyallup's heating season is long and damp rather than extreme. Normal January lows are about 33°F and the city averages about 40 inches of rain a year, so a furnace runs for months at a time. Summers are changing too: during the June 2021 heat wave, Sea-Tac Airport, the nearest official station, set an all-time record of 108°F on June 28. That is why many Puyallup homeowners replacing a furnace now add cooling at the same time.
Why so many Puyallup furnaces are due now
Puyallup's median home was built in 1987, and about 49% of homes date from the 1970s through the 1990s. South Hill grew quickly in the same period. Many of those homes are on their second furnace, and original 80% efficiency units from that era are reaching the end of their parts support.

Signs your furnace needs replacing
A furnace usually needs replacing when repairs keep coming back, safety parts fail, or the system can no longer heat the whole house. Common signs in Puyallup homes:
- Age: the furnace is 15 years or older, or still has its original 1980s or 1990s equipment.
- Repeat repairs: you have paid for more than one major repair in the last two heating seasons.
- Heat exchanger or carbon monoxide concerns: a technician found a cracked heat exchanger, or your CO alarm has sounded.
- Burner flame changes: a yellow or flickering flame instead of a steady blue one.
- Uneven heat: upstairs rooms or additions never warm up, or the furnace runs constantly.
- Rising bills: PSE gas or electric bills climb while your usage habits stay the same.
If you smell gas, leave the house and, once you are a safe distance away, call PSE at 1-888-225-5773 or 911.
Furnace and heating options for Puyallup homes
The right replacement depends on your fuel, your ductwork and whether you also want air conditioning. Here is how the main options compare.
| Option | Best for | What to know |
|---|---|---|
| High-efficiency gas furnace (95% AFUE and up) | Homes on PSE natural gas with room for PVC venting and a condensate drain | Lowest gas use. Needs a drain and new venting when replacing an older 80% furnace. |
| Standard gas furnace (80% AFUE) | Homes where venting or drain changes are impractical | Lower upfront cost, higher gas use over its life. |
| Electric furnace | Homes without gas service | Simple, but expensive to run. Replacing one with a heat pump can qualify for PSE's $1,500 conversion rebate. |
| Dual-fuel (gas furnace plus heat pump) | Gas homes that also want air conditioning | The heat pump carries most of the year; gas covers the coldest nights. PSE offers a $1,500 hybrid heat pump rebate when a ducted heat pump is paired with a gas furnace. See furnace vs. heat pump vs. hybrid systems. |
| Heat pump in place of a furnace | Electric-heated homes, or anyone who wants one system for heating and cooling | Efficient at Puyallup's winter temperatures. See heat pump installation in Puyallup. |
Sizing matters as much as the equipment. We size every replacement with a load calculation instead of matching the old furnace, which is often oversized. Read what size furnace your home needs.
What affects furnace replacement cost in Puyallup
Nationally, a new furnace costs an average of about $4,814 installed, and most homeowners pay between $2,823 and $6,896, according to Angi's 2026 cost data (updated September 2026). Your price in Puyallup depends on the fuel, efficiency, venting and ductwork in your home.
| Project (national figures from Angi, 2026) | Typical cost range |
|---|---|
| New furnace, installed (all fuel types) | $2,823 to $6,896 (average $4,814) |
| Natural gas furnace, installed | $3,800 to $10,000 |
| Electric furnace, installed | $2,247 to $8,116 (average $5,148) |
| Furnace and air conditioner replaced together | $5,000 to $12,500 (average $7,500) |
| Permits and inspections | $400 to $1,500 |
| Old furnace removal | $60 to $330 |
These are national averages, not a quote. We give every Puyallup homeowner a written, itemized price after a free in-home visit.
The biggest cost drivers are the type and efficiency of the new system, venting and gas line changes, ductwork condition, and where the furnace sits in the home.
- Efficiency and features: 95%+ AFUE, two-stage and variable-speed furnaces cost more upfront and run quieter and more evenly.
- Venting and drainage: moving from an 80% to a high-efficiency furnace means new PVC venting and a condensate drain.
- Location: crawlspace and attic furnaces, common in older valley homes, take more labor than garage or closet installs.
- Ducts: leaky or undersized ducts waste the efficiency you pay for. PSE offers duct sealing rebates on many older homes (see the rebate table below). We also offer Aeroseal duct sealing and duct cleaning.
- Adding cooling: pairing the furnace with an AC or heat pump adds cost but saves a second project later. See AC installation in Puyallup.
- Electrical: a heat pump or new circuit may need panel work. See electrical panel upgrades in Puyallup.

Rebates and incentives for Puyallup furnace projects
Most of Puyallup, including South Hill, gets electricity and natural gas from Puget Sound Energy, so PSE programs usually apply. The largest rebates go to heat pumps and hybrid systems, not to a gas furnace on its own.
| Program | Who it fits | Amount (checked September 2026) |
|---|---|---|
| PSE electric resistance to heat pump conversion | Homes heated by an electric furnace, baseboards or wall heaters | $1,500, plus $2,400 more through income-based Efficiency Boost |
| PSE hybrid heat pump | PSE gas customers adding a ducted heat pump to an existing or new gas furnace | $1,500, plus $2,400 more through income-based Efficiency Boost |
| PSE income-qualified heat pump | Income-eligible PSE customers switching from natural gas heat | $4,000 |
| PSE duct sealing and insulation | Site-built homes from 1989 or earlier | Up to $1,000 (duct sealing only, homes from 2000 or earlier: up to $550; Aeroseal advanced duct sealing: up to $1,250) |
| PSE attic insulation | Site-built homes from 1989 or earlier with 0 to 4 inches of insulation | $1.75 per sq ft, up to $3,500 |
| Tacoma Power heat pump incentives | The few addresses near Puyallup served by Tacoma Power | $1,000 air-source or $2,000 variable-speed when replacing electric heat; $1,000 variable-speed when replacing non-electric heat |
| Federal 25C tax credit | Equipment placed in service after Dec 31, 2025 | Ended |
PSE rebates require installation by a PSE Recommended Energy Professional or PSE Trade Ally, and programs change, so we confirm eligibility for your address before you buy. See our PSE rebates guide for more.
Permits for furnace replacement in Puyallup
A furnace replacement needs a mechanical permit, and usually a gas piping or electrical permit as well. Where you file depends on whether your address is inside Puyallup city limits.
| Your address | Mechanical and gas permits | Electrical permits |
|---|---|---|
| Inside Puyallup city limits | City of Puyallup permit portal (the city adopts the International Mechanical Code and International Fuel Gas Code) | Washington L&I (Puyallup does not run its own electrical program) |
| South Hill and other unincorporated areas | Pierce County | Washington L&I, or Tacoma Power in its service territory |
We pull the permits, schedule inspections and are on site for them, so you do not have to.
Our furnace replacement process
Most furnace replacements take one day from arrival to final testing. Here is what happens:
- Free in-home assessment. We check the current furnace, venting, gas line, ducts and thermostat, and ask about comfort problems.
- Load calculation and options. You get two or three choices with upfront prices and any rebates shown.
- Permits filed with the City of Puyallup or Pierce County, and L&I when electrical work is involved.
- Installation day. We protect floors, remove the old unit and haul it away.
- Safety and performance testing. Gas pressure, combustion, temperature rise, carbon monoxide and airflow are checked before we leave.
- Walkthrough and maintenance. We show you the thermostat and filter and schedule your first tune-up through our Comfort Club maintenance plan.

Furnace replacement FAQs for Puyallup
How long does a furnace last in Puyallup?
Most gas furnaces last about 15 to 20 years with yearly maintenance. Long, damp heating seasons and skipped tune-ups shorten that.
What's the difference between a gas and an electric furnace?
A gas furnace burns natural gas from PSE and is cheaper to run in most Puyallup homes. An electric furnace uses resistance heating, which is simple but costly to operate. Homes with an electric furnace are usually better served by a heat pump, which can qualify for PSE's $1,500 conversion rebate.
Should I replace my furnace with a heat pump?
Often, yes. Puyallup's mild winters suit heat pumps, and a heat pump adds air conditioning. If you want to keep gas as backup, a dual-fuel system pairs a heat pump with a gas furnace and can qualify for PSE's $1,500 hybrid heat pump rebate.
When is a ductless heat pump the right choice?
A ductless heat pump suits Puyallup homes without ductwork, additions, bonus rooms and older homes where running ducts would mean opening walls. It heats and cools, and one outdoor unit can serve several rooms. See our ductless systems page.
Are there rebates for a new furnace in Puyallup?
PSE's main heating rebates are for heat pumps and hybrid heat pump systems rather than a gas furnace on its own. PSE also offers duct sealing and insulation rebates on many older homes. The federal 25C tax credit ended for equipment placed in service after December 31, 2025.
Do I need a permit to replace a furnace in Puyallup?
Yes. Inside city limits the mechanical permit comes from the City of Puyallup; South Hill and other unincorporated addresses go through Pierce County. Electrical work is permitted through Washington L&I. We handle all of it.
How long does furnace replacement take?
Most straight replacements are finished in one day. Switching to a high-efficiency furnace with new venting, or adding a heat pump, can take one to two days.
