How much does a new furnace cost in Tacoma?

A new gas furnace install in Pierce County typically runs $5,500 to $10,500 depending on efficiency, size, and ductwork condition. High-efficiency 96%+ units cost more upfront and pay back on gas bills. Free written estimate.

How long does a furnace last?

15 to 20 years for a properly sized and maintained gas furnace. Once you cross the 15-year mark and repairs cost more than about a third of a replacement, replacement is usually the better economic call.

Gas or electric furnace, which is better?

In Tacoma, natural gas is still cheaper per BTU than electric resistance, so gas furnaces have lower operating cost. But a heat pump is often cheaper than either. We help you run the actual numbers before choosing.

How often should I replace my furnace filter?

Every 1 to 3 months for 1 inch filters, every 6 to 12 months for 4 to 5 inch media filters. Homes with pets, wildfire smoke exposure, or allergies should replace more often.

My furnace short-cycles or turns off. What is wrong?

Common causes: clogged filter, flame sensor issue, oversized unit, or a failing control board. We diagnose it before we quote a repair. No guessing.

A furnace is the most common heating system in Pierce County homes, and when it’s sized and installed correctly it will run quietly for fifteen to twenty years. When it isn’t, you get cold rooms, noisy ducts, and a utility bill that keeps climbing. GreenFlow installs gas and electric furnaces throughout Tacoma and the South Sound, and we do the math before we do the install.

Why Choose a Furnace

Even, whole home heat. No more cold spots and constant thermostat adjustments.
Energy efficiency. New furnaces are far more efficient than models from even ten years ago. An ENERGY STAR® certified gas furnace can be up to 15% more efficient than a standard model.
Quiet operation. Modern variable speed blowers run smoother and quieter than the single speed units they replace.
Built for the long haul. A well installed, properly sized furnace delivers 15 20 years of steady heat.
Safe and smart. Advanced diagnostics, smart thermostat compatibility, and safer combustion controls.

Your Furnace Options

Natural Gas Furnaces

The most common heating system in American homes. Gas furnaces burn natural gas and deliver warm air through your duct system. They heat quickly and, in most of Pierce County, cost less to operate through winter than electric resistance heat. Pair one with an air conditioner or a heat pump for a complete split system. Efficiency ratings run from 80% AFUE up to 98% AFUE on condensing models. Note: PSE does not offer a standalone gas furnace rebate, but if you pair your gas furnace with a heat pump on the same system, you qualify for the PSE Hybrid Heat Pump rebate at $1,500 standard or $2,400 Efficiency Boost.

Electric Furnaces

Electric furnaces use heating elements to generate warm air and move it through your ductwork. They’re simple, reliable, and a good option for homes without natural gas service. Paired with an AC condenser they form a standard split system. If you currently heat with an electric furnace, ask us about converting to a heat pump instead the PSE rebate is up to $2,400 and the operating cost difference is significant.

Dual Fuel Systems

A heat pump plus a gas furnace on the same ductwork. The heat pump handles most of the year; the furnace takes over in a cold snap. Excellent efficiency without giving up gas heat on the coldest nights.

Furnace FAQs

Gas or electric which is better in Pierce County? Gas furnaces are the more common choice here because they heat quickly and typically cost less to run in winter. Electric furnaces make sense where there’s no gas service, though in that situation a heat pump is usually the smarter long term option.

Furnace or heat pump? Heat pumps heat and cool in one system and are very efficient in our climate. Furnaces are dedicated heating systems that deliver strong, reliable heat in cold weather. Many homeowners here choose a dual fuel combination of both.

What size furnace do I need for a 1,500 sq ft home? Typically 45,000 70,000 BTU, but it depends on insulation, window area, air sealing, and duct capacity. An oversized furnace short cycles, wears out faster, and heats unevenly. We calculate it rather than guess.

How long does a furnace installation take? Usually one day for a straightforward replacement. We arrive in the morning and you have heat that evening.

Do I need a permit to replace a furnace? Yes. Mechanical permits are required by the City of Tacoma and by Pierce County, and gas piping work requires its own permit. We pull them and meet the inspector.

How do I know my furnace is failing? Uneven heating between rooms, banging or grinding noises, burning odors, rising heating costs, a yellow rather than blue pilot flame, or repeated repairs on a unit over 15 years old. See our repair page for a full symptom list.

How often should a furnace be serviced? Once a year, before heating season. Our Precision Comfort membership includes a 29 point inspection and a repair discount.

What Furnace Customers Say

“Our furnace was going out, knew it was time for a new one. Nathan at Greenflow was my first call. He was out same day to assess, and had an estimate by the end of the afternoon. Installation was smooth, and he was extremely communicative throughout the whole process.”
Oscar Lepe · Furnace replacement

“Nathan and Michael are one of a kind. They got the job done very quickly going over and beyond the call of duty. Removing two 275 gallon oil tanks and my old oil furnace as part of their bid, those tanks was not easy. Super clean, great communication, very easy to work with.”
Jeff Scott · Oil furnace + tank removal

“Our furnace was working fine. We figured we needed an inspection to be safe. The technician showed us, much to our surprise, how a neglected furnace can become a fire hazard without regular cleaning. He also was able to inspect and clean our AC unit. Both run like a top.”
Craig · Furnace inspection
