Explore Furnace Filter And Winter GuidesA Trane furnace is a gas furnace from Trane, the home heating and cooling brand of Trane Technologies, sold and installed through independent Trane dealers. Trane's 2026 national-average pricing puts a new Trane gas furnace at about $5,093 to $8,390 installed. Where you land depends on two choices. The first is efficiency, rated as AFUE, the share of fuel that becomes heat in your home. The second is staging, which sets how the furnace ramps its heat.
Filterbuy doesn't make furnaces. We make the filters that go inside them, in our own US plants. This guide covers Trane prices, models, efficiency, and warranty, then the filter details most furnace guides skip.
TL;DR
A new Trane gas furnace runs about $5,100 to $8,400 installed under Trane's 2026 national averages. Models range from 80% to 97.3% AFUE, and the 96% versions pay off fastest in homes with big winter gas bills. Register within 60 days for 10 years of parts coverage. Then keep the right-size filter in the slot and change it on schedule.
Key Takeaways
Trane's 2026 pricing guide puts installed costs between $5,093 (80% AFUE, single-stage) and $8,390 (96% AFUE, two-stage variable speed).
A 96% furnace burns about 17% less gas than an 80% furnace for the same heat.
Registering within 60 days of install lifts Trane parts coverage from 5 to 10 years. Labor isn't covered either way.

How Much Does A Trane Furnace Cost In 2026?
A Trane gas furnace costs about $5,093 to $8,390 installed, using the national averages in Trane's 2026 residential pricing guide. The 80% AFUE single-stage tier is the cheapest. The 96% AFUE two-stage variable-speed tier costs the most. Those prices don't include a thermostat, and your local quote will shift with home size, ductwork, and region.
Source: Trane residential pricing guide, updated May 26, 2026. National averages for the equipment shown, excluding accessories.
Your home and its ductwork drive most of the price. Ask about these line items before you sign:
Venting. Moving from an 80% furnace to a 96% condensing furnace (one that pulls extra heat from its exhaust) usually means new PVC vent pipes and a condensate drain.
Thermostat. A smart or communicating thermostat is priced separately.
Permits and gas work. Local permits and gas line changes add to the total.
Old furnace removal. Trane's install pricing includes hauling away the old unit, so make sure your quote does too.
The flagship Trane 96 Modulating Variable Speed furnace isn't in the published tier table. It typically quotes above the Premier range, so ask your dealer for a line-item price.
Which Trane Furnace Model Is Right For Your Home?
Trane now names its gas furnaces by efficiency and staging, such as the 96 Two-Stage Variable Speed (formerly the S9V2). Pick efficiency by climate first. The 80% models suit mild winters and tight budgets, while the 92% to 97.3% condensing models suit cold regions. Then pick staging for comfort and noise.
Availability varies by region. Confirm the model number on your quote.
Single-stage furnaces run at full blast every time. Two-stage furnaces sit on low most of the day, so rooms swing less. Modulating furnaces trim the flame in small steps for the tightest control.
What Do Trane Furnace Efficiency Ratings Mean?
AFUE, short for Annual Fuel Utilization Efficiency, is the share of a furnace's fuel that turns into heat for your home over a year. The federal minimum efficiency standard for gas furnaces is 80% AFUE, and Trane's gas furnaces meet or beat it. Put in money terms, a 96% furnace loses about 4 cents of each fuel dollar. An 80% furnace loses about 20 cents.
ENERGY STAR sets the bar higher. Its ENERGY STAR gas furnace criteria call for 97% AFUE or more in the U.S. North and 95% or more in the U.S. South. Only Trane's top models clear the northern bar, so check the model number if a rebate depends on it.
How Long Does The 96% AFUE Upgrade Take To Pay Back?
A 96% furnace needs about 17% less gas than an 80% furnace for the same heat, because 80 divided by 96 is 0.83. Trane's pricing puts the gap between the 80% and 96% Choice tiers at about $1,465 to $1,537. We ran the math on a $1,500 premium so you don't have to:
$400 a year in heating gas: about $67 saved a year, so roughly 22.5 years to pay back.
$800 a year: about $133 saved, so about 11.3 years.
$1,200 a year: about $200 saved, so 7.5 years.
$1,600 a year: about $267 saved, so about 5.6 years.
These Filterbuy estimates assume steady gas prices and leave out venting costs. With a big winter gas bill, the 96% furnace pays back in well under a decade. In a mild climate, an 80% furnace is often the better buy.
Trane Furnace Reviews: What Owners Praise And What They Flag
Trane owners tend to praise quiet operation and steady comfort on the two-stage and variable-speed models. The most common complaints in public reviews involve uncovered repair labor, uneven dealer quality, and waits for parts. Several trace back to the installer, so the dealer you choose matters as much as the model.
Before you sign a quote, ask the dealer:
Will you size the furnace with a Manual J load calculation, the industry standard for matching heat output to a house, instead of copying the old unit's size?
Will you register the Trane warranty for me within 60 days?
What does your labor warranty cover, and for how long?
Which filter does this furnace take, and where's the slot?
What Does The Trane Furnace Warranty Cover?
Trane's Registered Limited Warranty covers furnace parts for 10 years and the heat exchanger, the sealed part that passes heat into your air, for 20 years. Some higher-efficiency models carry a limited lifetime heat exchanger warranty. You'll need to register within 60 days of installation to get the 10-year parts term. Skip it, and the Base Limited Warranty gives you 5 years on parts. Neither covers labor.
The registered warranty can transfer to a new owner within 90 days of a home sale. In Florida, for home sales on or after July 1, 2024, skipping registration doesn't shorten the warranty. Ask your dealer what a labor plan costs.
Which Air Filters Fit A Trane Furnace?
Finding your Trane furnace filter size is quick. Pull out the filter you have now and read the nominal size printed on the frame, such as 16x25x1 or 20x25x5. That's the size to order. Most Trane furnaces take either a standard 1-inch filter in a return grille or blower slot, or a 5-inch media filter in a Trane Perfect Fit cabinet.
Perfect Fit cabinets use Trane's sizing, so a generic 5-inch filter may not seat correctly. Filterbuy makes Trane-compatible replacement air filters designed to fit Trane Perfect Fit and American Standard cabinets, plus standard 1-inch sizes. If your size isn't listed, we cut custom sizes to the eighth of an inch. Can't read the frame? Our guide on how to find the right furnace filter size walks you through measuring the slot.
Filterbuy tip: Replacing your furnace? Hold off on stocking up until the new unit is in. A new cabinet can be wider than the old one, and some installers add a Perfect Fit cabinet. Then write the filter size on the cabinet with a marker.
Choose your MERV rating by what's in your air. MERV 8 filters are the standard choice for most homes. MERV 11 filters suit homes with pets or heavy pollen. MERV 13 is the smoke-season pick, and the EPA suggests choosing at least a MERV 13 filter when you upgrade. As with sizing, confirm the right rating in your Trane furnace manual or with your HVAC technician. Here's how MERV ratings work tier by tier.
Change 1-inch filters about every 90 days, and sooner with pets or heavy use. Thicker 5-inch filters go longer between changes, and our guide to furnace filter thickness explains why. Follow the interval on the filter or in your manual, and see how often to change your HVAC filter for the full schedule.
Our Take As A Filter Manufacturer
We build filters, not furnaces, so we've got no stake in which brand heats your home. A gas furnace typically lasts 15 to 20 years with regular maintenance, and the filter is the one part most owners handle between yearly service visits. Pick the right size once and mark it on the cabinet. Then put replacements on a delivery schedule.
