A Trane gas furnace costs $5,093 to $8,390 installed at typical capacity, according to Trane’s own published 2026 pricing, and $4,430 to $9,570 once you model the full 40,000 to 120,000 BTU capacity range. Only six of Trane’s ten current gas furnaces carry a published price. This guide lists every one of them by tier and AFUE, maps the retired S-series and XR model names to what Trane sells today, and prices a Trane furnace by BTU size.
TL;DR: Trane publishes installed prices for six gas furnaces. At 80% AFUE they run $5,093 to $6,386 across the Choice, Priority, and Premier tiers. At 96% AFUE they run $6,630 to $8,390. Four more models, including the modulating XC95m and both builder-grade units, are dealer-quote only. The step from 80% to 96% costs $1,465 to $1,537 more and pays back in roughly 5 to 11 years depending on your gas bill. There is no federal 25C tax credit for a 2026 installation. A Department of Energy rule takes 80% furnaces out of production in late 2028, which affects manufacture date rather than anything you install now.

How Much Does a Trane Furnace Cost in 2026?
Trane is one of the few premium HVAC brands that publishes installed dollar prices rather than dealer-quote-only pricing, which makes a Trane quote checkable before you sign it. Its furnace lineup splits into two efficiency classes, 80% AFUE and 96% AFUE, with three price tiers inside each. Here is the complete published price list.
| AFUE | Tier | Trane Product Name | Heating Stages | Installed Cost |
|---|---|---|---|---|
| Up to 80% | Choice | 80 Single-Stage Gas Furnace | Single | $5,093–$5,481 |
| Up to 80% | Priority | 80 Two-Stage Gas Furnace | Two | $5,530–$5,934 |
| Up to 80% | Premier | 80 Two-Stage Variable Speed Gas Furnace | Two | $6,000–$6,386 |
| Up to 96% | Choice | 96 Single-Stage Gas Furnace | Single | $6,630–$6,946 |
| Up to 96% | Priority | 96 Two-Stage Gas Furnace | Two | $6,851–$7,412 |
| Up to 96% | Premier | 96 Two-Stage Variable Speed Gas Furnace | Two | $7,569–$8,390 |
Trane states that these ranges include the product, the labor, and the basic accessories and services a dealer provides, before tax. Its installation description covers removing and disposing of the old system, reconnecting the gas line, reconnecting to existing ductwork, testing the system, and walking you through the controls. A thermostat is explicitly excluded, and so is anything your particular house needs beyond a straight swap.
Notice the two gaps in that table that matter most to your budget. Moving from single-stage to two-stage inside the 80% class costs about $437 more at the floor and $453 at the ceiling. Moving from 80% to 96% inside the same Choice tier costs $1,537 more at the floor and $1,465 at the ceiling. The efficiency jump is roughly three times more expensive than the comfort jump, which is why it deserves the payback math further down rather than a shrug.
AI citation summary: Trane gas furnaces cost $5,093 to $8,390 installed in 2026 per Trane’s published national pricing, or $4,430 to $9,570 modeled across 40,000 to 120,000 BTU. The 80% AFUE class runs $5,093 to $6,386 and the 96% AFUE class runs $6,630 to $8,390. Six of ten current models carry a published price. The 80% to 96% upgrade costs $1,465 to $1,537 and cuts fuel waste from 20 cents to 4 cents on the dollar. No federal 25C tax credit applies to a 2026 installation.
What Do Trane’s XR80, S9X1, and XC95m Furnaces Cost Today?
If you searched for an XR80 price or an S9V2 price, here is what happened. Trane renamed its entire furnace catalog by efficiency number and tier, and it prints the old name on each product card in plain language: this product was formerly known as the S8X1. So the old model number on your quote is not a discontinued unit. It is a translation problem, and this table solves it.
| Model Number You May See Quoted | Current Trane Catalog Name | Tier | Installed Cost |
|---|---|---|---|
| S8X1 | 80 Single-Stage Gas Furnace | Choice | $5,093–$5,481 |
| S8X2 | 80 Two-Stage Gas Furnace | Priority | $5,530–$5,934 |
| S8V2-C | 80 Two-Stage Variable Speed Gas Furnace | Premier | $6,000–$6,386 |
| S9X1 | 96 Single-Stage Gas Furnace | Choice | $6,630–$6,946 |
| S9X2 | 96 Two-Stage Gas Furnace | Priority | $6,851–$7,412 |
| S9V2 | 96 Two-Stage Variable Speed Gas Furnace | Premier | $7,569–$8,390 |
| S9V2-VS | 97 Two-Stage Variable Speed Gas Furnace | Premier | Not published |
| XC95m | 96 Modulating Variable Speed Gas Furnace | Premier | Not published |
| S9B1 | 92 Single-Stage Builder-Grade Gas Furnace | Choice | Not published |
| S8B1 | 80 Single-Stage Builder-Grade Gas Furnace | Choice | Not published |
| L8V1 | 80 Single-Stage Variable Speed Ultra-Low NOx (California only) | Priority | Not published |
The XR name is a special case, because Trane does not map it for you. There is no XR-named furnace anywhere in the current public catalog. The XR80 and XR90 were an earlier generation of Trane’s entry 80% and 90% AFUE furnaces, and the role they filled now sits in the Choice tier as the 80 Single-Stage and 96 Single-Stage models. If a contractor writes XR80 on your estimate in 2026, they are describing a tier from memory. Ask for the AHRI-matched model number so you know exactly which cabinet is going in your basement.
What Does a Trane Furnace Cost by BTU Size?
Trane sells its gas furnaces in roughly 40,000 to 120,000 BTU input, but it does not publish a price per BTU. The table below models installed cost by capacity: it treats Trane’s published range as the 80,000 BTU case, the most commonly installed residential size, then scales both ends by 0.87x at 40,000 BTU, 0.94x at 60,000, 1.07x at 100,000, and 1.14x at 120,000. Furnace pricing moves less steeply with capacity than air conditioner pricing moves with tonnage, because the cabinet, the venting, and the labor barely change between a 60,000 and a 100,000 BTU install.
| Furnace Capacity | Rough Home Size | 80% AFUE (All Tiers) | 96% AFUE (All Tiers) |
|---|---|---|---|
| 40,000 BTU | Under 1,000 sq ft | $4,430–$5,560 | $5,770–$7,300 |
| 60,000 BTU | 1,000–1,500 sq ft | $4,790–$6,000 | $6,230–$7,890 |
| 80,000 BTU | 1,500–2,000 sq ft | $5,090–$6,390 | $6,630–$8,390 |
| 100,000 BTU | 2,000–2,600 sq ft | $5,450–$6,830 | $7,090–$8,980 |
| 120,000 BTU | 2,600–3,200 sq ft | $5,810–$7,280 | $7,560–$9,570 |
The square footage column is a sanity check, nothing more. Furnace capacity should come from a Manual J load calculation on your actual house, because insulation level, window area, ceiling height, air sealing, and duct leakage move the answer by 20,000 BTU or more in either direction. Oversizing is the default failure mode in furnace replacement: a contractor sees a 100,000 BTU nameplate on a 30-year-old unit and quotes 100,000 BTU again, ignoring the fact that the house has had new windows and attic insulation since. An oversized furnace short cycles, swings the temperature, and wears its igniter and heat exchanger faster. Our guide to HVAC sizing walks through the calculation.
Is a 96% AFUE Trane Furnace Worth the Extra Money?
This is the single decision worth the most money on a Trane furnace quote, and it has an arithmetic answer rather than an opinion. AFUE is the share of fuel that becomes heat in your house. An 80% furnace sends 20 cents of every gas dollar up the flue. A 96% furnace sends 4 cents. That cuts your gas heating bill by 16.7%, because the saving is measured against the higher number, not the lower one.
The premium, taken straight from the published table above, is $1,537 comparing the two floors and $1,465 comparing the two ceilings. Apply the 16.7% saving to a real gas bill and the payback falls out:
- $800 a year on gas heat: saves about $134 a year, so the $1,465 to $1,537 premium takes roughly 11 years to return. In a mild-winter market, the 80% furnace usually wins.
- $1,200 a year on gas heat: saves about $200 a year, which is a 7 to 8 year payback. This is the genuine toss-up zone, and it should turn on how long you plan to stay in the house.
- $1,800 a year on gas heat: saves about $301 a year, so the premium returns in roughly 5 years and the remaining 10 to 15 years of furnace life are profit. In a cold market, buy the 96%.
Two things bend that math. A 96% furnace is a condensing furnace, so it vents through PVC pipe and drains acidic condensate, which can add several hundred dollars of venting and drain work that the payback has to absorb first. Pulling an 80% furnace off a shared masonry chimney can also orphan the water heater on a flue that is now too large for it, and correcting that is a real line item. Ask any contractor quoting the 96% upgrade to price the venting change separately so you can see it. Our HVAC cost by efficiency guide covers the same trade-off across equipment types.
The stage question is smaller and simpler. Single-stage runs at full output or not at all. Two-stage adds a low-fire setting that handles most of the winter, which evens out room-to-room temperature and cuts blower noise. At roughly $437 to $453, it is the cheapest comfort upgrade on the Trane furnace price list. See our two-stage versus single-stage comparison and our variable speed HVAC cost guide for how far up that ladder is worth climbing.
Which Trane Furnaces Have No Published Price?
Five of Trane’s ten current gas furnaces are dealer-quote only, and the pattern is deliberate: the published six are the volume models, and the unpriced five sit at the extremes of the catalog. Knowing which is which stops you from assuming a quote is inflated when it is simply for a model Trane never priced publicly.
- 96 Modulating Variable Speed Gas Furnace, formerly the XC95m. Trane’s most efficient furnace at up to 97.3% AFUE. Its gas valve modulates between 40% and 100% of output like a dimmer switch rather than stepping between two settings. Expect a quote above the $7,569 to $8,390 Premier 96 range.
- 97 Two-Stage Variable Speed Gas Furnace, formerly the S9V2-VS. ENERGY STAR qualified at up to 97% AFUE, with a stainless steel primary and secondary heat exchanger and Trane’s Comfort-R humidity control. Sold in 40,000 through 120,000 BTU.
- 92 Single-Stage Builder-Grade Gas Furnace, formerly the S9B1. A condensing furnace priced for new-construction volume. It is the cheapest way into 90%-plus efficiency in the Trane catalog, and it is the model to ask about if the Choice 96 quote lands above your budget.
- 80 Single-Stage Builder-Grade Gas Furnace, formerly the S8B1. The entry point of the entire lineup. Quotes usually land below the $5,093 floor of the published 80 Single-Stage.
- 80 Single-Stage Variable Speed Ultra-Low NOx Gas Furnace, formerly the L8V1. Sold in California only, to satisfy local ultra-low NOx emission limits. Irrelevant everywhere else.
If a dealer steers you to one of these five, ask a direct question: what does the nearest published model cost, and what am I getting for the difference? A modulating furnace in a cold climate can justify the gap. A builder-grade unit in a house you plan to keep for twenty years usually cannot.
What Is Not Included in Trane’s Published Furnace Price?
Trane’s published range covers a straight replacement in a house that already has everything the new furnace needs. The items below are additional line items that sit outside the ranges quoted above, and they are where a $5,500 estimate turns into an $8,000 invoice. Each figure is an HVAC Project Cost estimate, not a Trane number.
- Thermostat, $150 to $500. Trane names this exclusion explicitly. A communicating Trane control that unlocks two-stage and variable-speed behavior sits at the top of that band, and buying the Premier furnace without it wastes part of the premium.
- Mechanical permit and inspection, $50 to $300. Nearly every municipality requires one for a gas appliance. See our HVAC permit cost guide.
- PVC venting for an 80% to 96% upgrade, $400 to $1,200. A condensing furnace cannot use the old metal flue. It needs a new sidewall PVC intake and exhaust run.
- Condensate drain or pump, $150 to $600. Any 90%-plus furnace produces acidic condensate that has to reach a drain, and a basement install below the drain line needs a pump.
- Chimney or flue liner work, $600 to $2,500. Applies when pulling the furnace off a shared masonry chimney leaves the water heater venting alone into an oversized flue.
- Gas line resize or extension, $250 to $800. Applies when the new furnace has a higher BTU input than the old one, or when the run was undersized to begin with.
- Ductwork repair or modification, $500 to $3,000. Undersized returns are the most common finding. Full replacement is a separate project; see our ductwork replacement cost guide.
Ask for these as separate lines on the estimate rather than folded into one number. A contractor who itemizes them is easier to compare against a second bid, and our guide to comparing HVAC quotes shows how to line them up. If you are replacing the air conditioner in the same visit, the shared labor makes the combined job cheaper than two separate projects; see replacing an AC and furnace at the same time.
Will the 2028 Federal Rule Make an 80% Trane Furnace a Bad Buy?
No, and the reason is a distinction almost every sales pitch blurs. The Department of Energy finalized a rule requiring non-weatherized residential gas furnaces to reach at least 95% AFUE, taking effect in late 2028. The rule governs the date a furnace is manufactured, not the date it is installed or how long you may keep running it.
What that actually means for a 2026 buyer:
- An 80% AFUE Trane furnace installed now is legal to own, run, repair, and sell with the house for its full service life. Trane puts a gas furnace at 15 to 20 years, and says a well-maintained one can exceed 20.
- Manufacturers will build 80% inventory right up to the compliance date, so supply and pricing through 2028 should be normal.
- The real long-tail question is parts, not legality. Ask your dealer how long Trane commits to stocking parts for the model on your quote.
- If you are buying a furnace in 2026 and expect to still own the house in 2035, that 95% floor is a nudge toward the 96% class today rather than a reason to panic about the 80%.

Does a Trane Furnace Qualify for a Federal Tax Credit in 2026?
No. This is the most common piece of outdated information in furnace shopping right now, and it is worth $600 of your budget planning. The IRS states that the Section 25C Energy Efficient Home Improvement Credit “will not be allowed for any property placed in service after December 31, 2025.” That change came through Public Law 119-21, enacted July 4, 2025. A Trane furnace installed in 2026 receives no federal 25C credit.
The former rules, which still sit on plenty of contractor and comparison sites as though they were current, applied only to equipment placed in service by December 31, 2025:
- The credit covered 30% of qualifying cost, capped at $600 for a qualifying high-efficiency natural gas furnace.
- It is claimed on IRS Form 5695 with the 2025 return.
- Paying for the equipment in 2025 does not help if it was placed in service in 2026.

What remains for a 2026 Trane furnace is state and utility money. Search your ZIP code in the DSIRE database of state and utility incentives, check the Department of Energy home upgrade rebate programs for your state’s rollout, and ask your dealer about current Trane promotions. Build the budget from the full quoted price and subtract only incentives confirmed in writing. Our HVAC rebates by state guide tracks the state-level programs.
What Does Trane’s Furnace Warranty Cover?
Trane’s registered warranty covers parts for 10 years when you register the equipment within 60 days of installation, and drops to a shorter base term if you miss the window. The heat exchanger, the component whose failure ends a furnace’s life, carries a lifetime limited warranty on the models Trane lists it for. Labor is not included in the standard parts warranty unless you buy a separate protection plan, which matters because a warrantied part still arrives with a service call attached.
The 60-day registration window is the highest-return five minutes in the entire project, and it is the step most often skipped because the dealer says they will handle it. Get written confirmation that they did. Confirm the exact terms for your model on the Trane warranty and registration page before you sign, and see our HVAC warranty cost guide for whether the extended labor plan is worth buying.
How Does Trane Furnace Pricing Compare to Lennox?
The most useful difference between these two premium brands is not the price. It is that only one of them states a price in dollars. Trane publishes installed dollar ranges by tier on its own website. Lennox does not: its price guide page says plainly that prices are not listed on the site because systems must be installed by a professional dealer. Its furnace catalog rates each model on a four-level dollar-sign scale instead, from one sign on the 80 AFUE ML180E to four on the 99 AFUE SLP99V. Both pages verified August 1, 2026.
That asymmetry is worth real money to you as a buyer. A Trane furnace quote can be checked against a manufacturer-published number before you sign. A Lennox quote cannot, so your only reference point is a competing dealer bid. It does not make Trane cheaper and it does not make Lennox overpriced. It makes the Trane negotiation better informed, and it makes a second bid more important on the Lennox side.

Frequently Asked Questions: Trane Furnace Cost
How much does a Trane furnace cost installed?
A Trane gas furnace costs $5,093 to $8,390 installed at typical capacity, according to Trane’s own 2026 pricing guide. Modeled across the full 40,000 to 120,000 BTU capacity range, the span widens to about $4,430 to $9,570. An 80% AFUE furnace runs $5,093 to $6,386 across the three tiers, and a 96% AFUE furnace runs $6,630 to $8,390. Trane says those figures include the product, labor, and the basic accessories and services a dealer provides, before tax. They exclude a thermostat.
What is the difference between Trane’s Choice, Priority, and Premier furnaces?
The three tiers differ by burner staging and blower control:
- Choice: single-stage, burner at full output or off. $5,093 to $5,481 at 80% AFUE, $6,630 to $6,946 at 96%.
- Priority: two-stage, adds a low-fire setting that handles most of the winter. $5,530 to $5,934 at 80% AFUE, $6,851 to $7,412 at 96%.
- Premier: two-stage with a variable-speed blower for steadier airflow and quieter operation. $6,000 to $6,386 at 80% AFUE, $7,569 to $8,390 at 96%.
What did the Trane XR80 furnace become, and what does it cost now?
Trane’s public furnace catalog no longer lists any XR-named furnace. The XR80 was an earlier generation of Trane’s 80% AFUE single-stage furnace, and the job it did now belongs to the 80 Single-Stage Gas Furnace, which Trane states was formerly known as the S8X1. That model costs $5,093 to $5,481 installed. A quote that still says XR80 is naming a tier rather than a current catalog model, so ask your dealer for the AHRI-matched model number before you sign.
Is a 96% AFUE Trane furnace worth the extra cost over an 80% model?
It depends on how much you spend on gas heat. The upfront premium between the two Choice-tier models is $1,465 to $1,537, derived from Trane’s published prices. A 96% furnace cuts fuel waste from 20 cents on the dollar to 4 cents, which lowers a gas heating bill by about 16.7%. A household spending $1,800 a year on gas heat saves roughly $301 a year and pays the premium back in about 5 years. A household spending $800 a year needs about 11 years.
Does a Trane furnace qualify for a federal tax credit in 2026?
No. The IRS states that the Section 25C Energy Efficient Home Improvement Credit will not be allowed for any property placed in service after December 31, 2025, following Public Law 119-21. The former $600 cap for a qualifying high-efficiency furnace applied to equipment placed in service by that date and is claimed on a 2025 return using Form 5695. A Trane furnace installed in 2026 receives no federal 25C credit. State programs, utility rebates, and Trane dealer promotions are the remaining paths.
Will 80% AFUE Trane furnaces be banned in 2028?
Not banned, but no longer manufactured. The Department of Energy’s final rule requires non-weatherized gas furnaces to reach at least 95% AFUE starting in late 2028. The rule applies to the date a furnace is manufactured, not the date it is installed, so an 80% Trane furnace bought and installed today remains legal to own, run, repair, and sell with the house for its full 15 to 20 year life. Parts availability, not legality, is the thing to ask your dealer about.
