Furnace Replacement Cost - What It Actually Costs, Quoted Free

How Much Does Furnace Replacement Cost in Fort Worth?

A full furnace replacement in Fort Worth typically runs $4,800 to $9,600 for a standard-efficiency unit installed, with most single-family homes landing between $5,200 and $7,800. High-efficiency systems (90%+ AFUE) start around $6,800 and can reach $12,500 or more when ductwork modifications, permits, and upgraded filtration are included. These are 2026 figures based on what we’re quoting across Tarrant County right now, not national averages pulled from a database.

Before you read further, understand this: the furnace itself is only part of the bill. Labor, permit fees, disposal of the old unit, and the condition of your existing ductwork all move the final number. We’ll break down exactly where the money goes below, so you can separate a fair quote from one that’s padded or one that’s suspiciously cheap.

Furnace Replacement Cost Breakdown (2026)

Here’s where the money actually goes on a typical Fort Worth furnace replacement. These are line-item ranges from jobs we’ve quoted and completed across Fort Worth, Arlington Heights, Fairmount, Wedgwood, and the northern suburbs up toward Keller and Saginaw.

Line Item	Typical Range (2026)	Notes
Furnace unit (80% AFUE, single-stage)	$1,800 – $3,200	Goodman, Rheem, York, Bryant base models
Furnace unit (92 – 95% AFUE, two-stage or modulating)	$3,000 – $5,500	Carrier, Trane, Lennox, Daikin mid to upper tier
Installation labor (standard swap)	$1,200 – $2,500	Includes removal of old unit, mounting, gas line tie-in, venting check
Permit and city inspection	$150 – $450	Fort Worth mechanical permit; varies by scope
Ductwork modifications or transitions	$400 – $2,800	Only when the existing plenum or return does not match the new unit
Flue / venting upgrade	$300 – $1,500	High-efficiency units may need PVC venting instead of metal flue
Thermostat (new or replacement)	$80 – $350	Basic programmable to smart thermostat
Old unit disposal and haul-away	$100 – $250	We remove the old furnace and leave the site clean; included in most quotes
Gas line modification	$150 – $600	Only if the existing line is undersized for a larger BTU furnace

Add those together and you can see why the “furnace unit price” you find online has almost nothing to do with the installed price you’ll actually pay. A $2,200 furnace on a supply-house website still needs labor, permit, venting, a thermostat, and disposal before it heats your house.

What Moves a Fort Worth Furnace Replacement Up or Down

Two identical 2,000-square-foot houses in Fort Worth can have furnace replacement quotes that differ by $3,000 or more. Here’s why.

Age and condition of the existing ductwork. If the plenum (the sheet-metal box connecting the furnace to the ducts) was built for a unit from 1998, it often doesn’t match a modern unit’s dimensions. A transition piece might cost $400. Rebuilding a rusted return drop in a pier-and-beam house in Fairmount can run $1,800.

Access to the furnace. In Fort Worth’s older neighborhoods like Ryan Place or Mistletoe Heights, furnaces often sit in tight hall closets or attic spaces with 24-inch access hatches. Cramped access means more labor hours, sometimes a partial disassembly, and occasionally a platform rebuild. In newer Saginaw or Crowley homes with spacious attic utility decks, the same swap is straightforward.

Fuel type and venting. If you’re replacing an 80% AFUE unit with a 95%+ unit, the old metal flue usually can’t be reused. High-efficiency furnaces condense and need PVC or polypropylene venting routed to an exterior wall. In a two-story house where the furnace sits in a first-floor closet, that vent run can add $800 – $1,500.

Furnace size (BTU output). A 40,000 BTU furnace for a 1,200-square-foot condo in West 7th costs less than an 80,000 BTU or 100,000 BTU unit for a 2,800-square-foot house in Mira Vista. The difference in equipment cost alone is often $600 – $1,400. The labor difference is smaller, but the equipment delta shows up on every quote.

Brand and tier. We install and service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. A Goodman 80% AFUE single-stage furnace might be the right call for a rental property. A Trane or Lennox modulating unit with a variable-speed blower will cost more up front but runs quieter and maintains steadier temperatures. We’ll quote the unit that fits the house and your budget, and explain the trade-offs in plain terms before you commit.

What Affects Furnace Replacement Pricing in Fort Worth

Beyond the line items, a handful of local and practical factors shape what you’ll actually be quoted in Tarrant County. Here’s what our techs see most often.

• House size and heat load: Fort Worth homes range from 900-square-foot bungalows near South Main to 4,000-square-foot two-story builds in Tanglewood. Furnace size follows heat load, not square footage alone. A drafty 1950s house with original windows in Ridglea needs more BTU per square foot than a tight 2015 build in Walsh Ranch. Bigger furnace, bigger price.
• Efficiency level (AFUE): An 80% AFUE furnace turns 80 cents of every gas dollar into heat; a 95% AFUE turns 95 cents. The 80% units are cheaper to buy and install. The 95%+ units qualify for utility rebates (Atmos Energy has offered Fort Worth rebates for high-efficiency furnace installs, typically $200 – $500 depending on the program year) and cut winter gas bills by 12 – 18%.
• Ductwork condition: If your supply and return ducts are still solid and sized right, the replacement stays simple. If the return air drop is undersized (common in 1970s and 1980s Fort Worth production homes), the new furnace will strain unless it’s rebuilt. We’ll show you what we’re seeing and put the ductwork reality in writing before work begins.
• Single-stage vs. two-stage vs. modulating: A single-stage furnace is on or off: full fire or nothing. A two-stage has a low and high fire. A modulating furnace ramps between 35% and 100% output in small increments. Equipment cost climbs with each step, and so does comfort and quiet. The right call depends on your house and how you live in it. We stock and install all three.
• Seasonal timing: Fort Worth winters are mild compared to Minneapolis, but heating demand spikes in December and January. Furnace replacement pricing is steady year-round because we carry inventory and quote at the same margin regardless of month. What changes in peak season is lead time. If your furnace dies during a January cold snap, we can usually install within 24 – 48 hours. In shoulder months like October or March, same-day or next-day service is common. Call (817) 730-5369 to ask about current scheduling.
• Permits and local code requirements: The City of Fort Worth requires a mechanical permit for furnace replacement, and the installation must pass a city inspection. We pull the permit, schedule the inspection, and handle any corrections. This is part of why the cheap no-permit quote from a trunk-slammer is cheap: they’re skipping a step that protects your house and your insurance coverage.

Furnace Replacement vs. Furnace Repair: Which One Do You Actually Need?

This is the question we get more than any other, and the honest answer is: it depends on the age of the unit, the cost of the repair, and what’s already failed before. Here’s a direct framework we use with Fort Worth homeowners.

Repair makes sense when:

• The furnace is under 12 years old
• The repair is under $700 (most furnace repairs in Fort Worth run $150 – $700 depending on the part)
• The heat exchanger passes a visual and combustion test
• You haven’t had repeated breakdowns in the last two winters

Replacement makes more sense when:

• The furnace is over 15 years old
• The heat exchanger is cracked or rusted through (this is a safety shutdown situation, not a patch job)
• The repair quote exceeds 40 – 50% of a replacement unit’s installed cost
• You’ve called for repairs twice in the last 12 months and the unit still isn’t right

One more thing on heat exchangers: a cracked heat exchanger can leak carbon monoxide into the house. If we find one, the furnace gets shut down and red-tagged. That’s not a scare tactic; that’s code and conscience. We’ll show you the crack with a borescope camera and give you a written replacement quote before we leave the driveway.

Step-by-Step: How a Furnace Replacement Works with Dalton Heating & Air

Here’s exactly what happens when you call us for a replacement. No mystery, no surprises.

Step 1: You call (817) 730-5369 and talk to a real person.

A live person answers, 24/7. Not a voicemail, not a callback service. You describe the situation, and we schedule a visit inside a window you choose. Evening and weekend slots are available.

Step 2: A background-checked, uniformed technician arrives at the scheduled time.

Before the tech arrives, you know who’s coming. Background-checked, uniformed, and factory-trained to service all nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The tech greets you, puts on shoe covers, and gets to work.

Step 3: We measure, inspect, and explain what we find.

The tech checks the existing furnace, the ductwork transitions, the gas line, the venting, and the electrical. If the furnace is repairable, we’ll tell you plainly. If it needs replacement, we’ll explain why in terms you can understand, not trade jargon. You’ll hear words like “heat load,” “AFUE,” and “return drop,” and we’ll translate each one on the spot.

Step 4: We hand you a written price before any work begins.

This is the Dalton Standard: the price is in writing and it’s final. It includes the unit, labor, permit, disposal, and any ductwork transitions. No haggling, no surprise line items at the end. The number we write down is the number you pay. Period.

Step 5: We install, test, and inspect.

Most replacements are completed in one day. The tech installs the new furnace, connects the gas and venting, checks manifold pressure and temperature rise, and runs a full combustion test. Then the installation is scheduled for city inspection (if your job required a permit).

Step 6: We walk the job with you and leave the site clean.

We show you the finished install, walk you through the new thermostat, and answer every question before we pack up. The work area is left cleaner than we found it, and the old unit goes with us. No debris, no tape, no mess.

Step 7: The repair or replacement is guaranteed in writing for a full year.

Every job includes a written guarantee, not a verbal promise. If something isn’t done right within 365 days, we come back at no charge and fix it. That’s our 365-Day Done Right Promise, and it’s been part of The Garrison Standard since 2003.

How to Save on Furnace Replacement in Fort Worth

You don’t have to pay top dollar to get a solid furnace installed. Here are practical, specific ways to keep the price reasonable without cutting corners.

• Get the right size, not the biggest size. An oversized furnace costs more up front, cycles on and off constantly, and wears out faster. A proper heat-load calculation (we do this on every replacement, not a rule-of-thumb guess) ensures you pay for the BTU you actually need.
• Ask about manufacturer rebates. Carrier, Trane, Lennox, and others run seasonal rebates on high-efficiency units. These stack on top of any utility rebate from Atmos Energy for Fort Worth customers. Current rebate programs change quarterly; we’ll check what’s active when you get a written estimate.
• Consider an 80% AFUE unit if your house is small and well-insulated. If you live in a tight condo or a small bungalow with updated windows, a high-efficiency furnace may never pay back its premium. We’ll do the math with you and tell you if the numbers support the upgrade or not.
• Replace the furnace and AC together if both are aging. If your AC is 15+ years old and the furnace is going, replacing both as a matched system avoids paying for a second set of labor and ductwork modifications later. An AC installation in Fort Worth runs $3,500 – $7,500, and bundling with a furnace replacement can save $800 – $1,500 in labor overlap.
• Don’t skip the permit. It’s not a place to save. An unpermitted furnace replacement can void your homeowner’s insurance coverage if a fire or gas issue traces back to the install. If someone offers you a no-permit furnace replacement for a suspiciously low price, walk away. The $150 – $450 permit is the cheapest insurance you’ll ever buy.
• Call us for a free, written estimate. Estimates from Dalton Heating & Air Fort Worth are free, and the price is in writing before you decide anything. Call (817) 730-5369 to schedule. Even if you don’t hire us, you’ll have a detailed, itemized quote to compare against other bids.

Furnace Replacement Cost FAQs – Fort Worth

These are the questions Fort Worth homeowners ask us most often, answered with real numbers.

How much should I budget for a furnace replacement in Fort Worth in 2026?

A realistic budget is $5,200 – $7,800 for a standard mid-efficiency replacement in a typical Fort Worth home. That covers the furnace, labor, permit, disposal, and standard ductwork transitions. If you want a high-efficiency modulating unit or have significant ductwork work, budget $8,000 – $12,500. Call (817) 730-5369 for a written quote specific to your house; estimates are free.

Is it cheaper to repair or replace a furnace?

If the repair is under $700 and the furnace is under 12 years old, repair usually wins. If the repair is over $700, the unit is over 15 years old, or the heat exchanger is cracked, replacement is the better financial call. Most furnace repairs in Fort Worth run $150 – $700 depending on the failed part, so it’s often worth a diagnostic visit first. We’ll show you the numbers and let you decide, no pressure either way.

Can you install a furnace the same day I call?

In most cases, yes, and especially during Fort Worth’s milder months. During winter cold snaps, lead times can stretch to 24 – 48 hours. We carry inventory of major brands and sizes in our local warehouse, so same-day or next-day installation is common. Call (817) 730-5369 and a live person will tell you exactly what’s available today.

What does a high-efficiency furnace save on gas bills in Fort Worth?

A 95% AFUE furnace uses about 15 – 18% less gas than an 80% AFUE unit to produce the same heat. On a typical Fort Worth winter gas bill of $80 – $120 per month, that’s roughly $12 – $22 per month in heating season, or $60 – $100 per winter. Over a 15-year furnace lifespan, the efficiency upgrade often pays for itself, plus the house is more comfortable and the utility rebates help offset the initial cost difference.

Do I need a permit to replace a furnace in Fort Worth?

Yes. The City of Fort Worth requires a mechanical permit for furnace replacement, and the job must pass a city inspection. We pull the permit, handle the inspection, and correct anything the inspector flags. This is part of the written price we quote. A company that skips the permit is skipping a code requirement and putting your insurance coverage at risk. That’s not a corner you want cut.

What furnace brands do you install?

Dalton Heating & Air Fort Worth is factory-trained to install and service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The right brand for your house depends on your budget, efficiency goals, and the size of the house. We’ll give you written options and explain the trade-offs of each in plain English.

Why Fort Worth Homeowners Choose Dalton Heating & Air

We’re not the cheapest option you’ll find on a search results page, and we’re fine with that. Cheapest usually means no permit, no inspection, no guarantee, and a phone number that stops answering in February. Here’s what we do differently.

Written price before anything starts. The Garrison Standard, in effect since 2003 across every Garrison Partners location, requires that the price be in writing before work begins. No verbal estimates that drift upward. No “we found something else” mid-job upcharges. The number on your estimate is the number on your invoice.

Background-checked, uniformed technicians. You know who’s coming to your door before they arrive. Every Dalton technician passes a background check, wears a uniform, and is factory-trained on all nine major brands we service. When you schedule a visit, you get the tech’s name, and you get them inside your scheduled window.

Written guarantee, not a verbal promise. Every furnace replacement includes a written guarantee covering the work for a full year. If something isn’t done right within 365 days, we come back at no charge. That’s not an extended-warranty upsell; it’s the standard on every single job. The 365-Day Done Right Promise means the job is covered for a full year, not a 30-day window.

Live phone answer, 24/7. When your furnace dies at 2 a.m. in January, you call (817) 730-5369 and a live person picks up. Not a voicemail tree, not an answering service that takes a message and “maybe someone will call you back.” A real person, any hour, any day, including holidays.

We leave the site clean. The old furnace goes with us. The work area is swept and wiped down. No debris in the attic, no tape on the floor, no mess in the closet. The Garrison Code is simple: arrive inside the window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year.

Marco Benitez, who leads the Dalton Heating & Air Fort Worth team, has built the business around one principle: we treat your house like we’d want ours treated if a contractor were working in it. That means showing up when we say we will, charging the price we wrote down, and fixing anything that isn’t right. It’s not complicated, and it shouldn’t be rare.
