AfterHow Much Does Furnace Replacement Cost in Dallas?
A full furnace replacement in Dallas, TX typically runs between $4,200 and $8,900 for a standard single-family home as of 2026. Most Dallas homeowners pay around $5,800 to $7,200 for a mid-efficiency gas furnace with professional installation, including removal of the old unit. High-efficiency models (90%+ AFUE) or installations requiring new ductwork, venting changes, or electrical upgrades can push the total to $10,000 – $14,000. The price you’ll pay depends on furnace size (BTU output), efficiency rating, brand, and whether your existing ductwork and gas lines can be reused.
At Brandt HVAC Co Dallas, you’ll get a written price before any work starts. No surprise line items, no vague allowances for “miscellaneous” charges. What we quote is what you pay, and every installation includes our 365-Day Done Right Promise: if it’s not done right, we make it right.
Furnace Replacement Cost Breakdown (2026)
Here’s how the numbers break down for the Dallas market. These ranges reflect actual installed costs, not just equipment prices.
| Cost Component | Typical Range (Dallas, 2026) |
|---|---|
| Furnace unit (80% AFUE, single-stage) | $1,100 – $1,900 |
| Furnace unit (96% AFUE, two-stage) | $2,100 – $3,600 |
| Furnace unit (97%+ AFUE, variable-speed) | $3,200 – $5,200 |
| Labor & installation | $1,000 – $2,800 |
| Sheet metal, venting, gas line work | $250 – $600 |
| Electrical (new circuit if needed) | $150 – $450 |
| Permit & inspection fees | $100 – $300 |
| Old furnace removal & disposal | $75 – $250 |
| Thermostat (if upgraded) | $80 – $350 |
Three things swing these numbers most. First, furnace size: a 1,500-square-foot Dallas ranch needs a different BTU output than a 3,800-square-foot two-story in Lake Highlands, and the larger unit costs more. Second, efficiency: an 80% AFUE furnace is the budget option, but Dallas winters, while mild compared to Minneapolis, still have stretches of nights in the 20s and 30s, and a 96% two-stage unit can cut your January gas bill noticeably. Third, installation complexity: if your existing furnace is in a finished attic, a tight closet, or a basement with a low ceiling, labor hours and sheet metal work go up.
You’ll also see line items for permit fees. The City of Dallas requires a mechanical permit for furnace replacement, and we handle that paperwork as part of the job. If a contractor tells you a permit “isn’t necessary,” walk away. It is, and skipping it means no third-party inspection of the gas connections and venting, which is exactly the kind of thing you don’t want discovered at 3 a.m.
What Affects Furnace Replacement Pricing in Dallas
- Home size and furnace BTU output. A 60,000 BTU furnace for an 1,800-square-foot home in east Dallas costs less than a 100,000 BTU unit for a 3,200-square-foot home in Preston Hollow. The larger the heat load, the larger the unit, the higher the equipment cost. It’s that straightforward.
- Efficiency rating (AFUE). An 80% AFUE furnace sends 20 cents of every gas dollar up the flue. A 96% AFUE unit sends 4 cents. The high-efficiency unit costs $1,000 – $2,500 more up front, and Dallas homeowners who plan to stay in the house 5+ years usually make that back in gas savings.
- Venting changes. If you’re switching from an 80% furnace to a 90%+ condensing model, you may need new PVC venting installed through a side wall instead of the existing metal flue. That’s labor and material, and it’s one of the most common reasons a “simple swap” turns into a larger job.
- Ductwork condition. Dallas attics get brutally hot in summer, and older flex duct can be degraded, disconnected, or undersized. If your ducts leak, a new furnace won’t fix the comfort problem, and you’ll be paying to heat the attic. We’ll tell you honestly if your ducts need sealing or replacement before or during installation.
- Brand and warranty length. Goodman and Rheem replacement parts are generally less expensive than Carrier or Trane parts, and the upfront unit cost reflects that. Longer manufacturer warranties (10 years for parts is standard on most brands now) also factor into price. We service and install all major brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so you’re not locked into one manufacturer’s markup.
- Time of year. Dallas demand for furnace work peaks during the first hard cold snap of the season, usually November or December. If your furnace dies during a freeze, you’re in the same queue as a few thousand other homeowners. Scheduling replacement in spring or fall often means faster scheduling and occasionally better equipment pricing from distributors. That said, we staff our phones with a live person 24/7, so if your furnace fails at midnight in February, someone answers and starts the process.
How Much Does Furnace Replacement Cost by Type in Dallas?
Here’s how the installed numbers shake out by furnace type, which is the question most homeowners actually mean when they ask “how much does a furnace cost.”
- Basic 80% AFUE single-stage furnace: $4,200 – $6,500 installed. The lowest upfront cost. It’s a simple, reliable machine, but it’s less efficient than modern minimum standards in some states. Still a common choice in Dallas rental properties and smaller homes.
- 96% AFUE two-stage furnace: $6,000 – $8,900 installed. The sweet spot for most Dallas homeowners. Two stages mean it runs on a low setting for mild days and ramps up only when temperatures drop, which saves gas and keeps temperatures more even across the house.
- 97%+ AFUE variable-speed furnace: $8,500 – $14,000 installed. Variable-speed, also called modulating, means the furnace adjusts its heat output in tiny increments instead of just “low” and “high.” Costs more, runs quieter, delivers the most even heat. Often paired with a high-end thermostat upgrade.
Dallas market context matters here. Our winters are short, but they’re not nonexistent. The February 2021 freeze, when the grid failed and many homes saw frozen pipes and furnace failures, is still fresh in local memory. A furnace that handles sustained cold efficiently isn’t just a comfort upgrade, it’s a hedge against the next cold snap. Many Dallas homeowners size their replacement choice to handle a week of 20-degree nights, even if that only happens once every few years.
Furnace Replacement vs. Furnace Repair: When to Make the Call
Repair costs run $150 – $700 for most furnace issues in Dallas. Replacement costs $4,200 – $14,000. The classic rule of thumb is: if the repair cost times the furnace age (in years) exceeds $5,000, replacement starts to make more sense. A $500 repair on a 15-year-old furnace? That’s a repair that buys you time, not a long-term solution.
You’re generally better off replacing when, first, the heat exchanger is cracked, since that’s both a carbon monoxide risk and a repair that often approaches 40 to 50 percent of new-furnace cost. Second, when the furnace is over 15 years old and a major component like the blower motor or control board fails. Third, when efficiency is below 80% AFUE and your gas bills have crept up year after year. A fourth sign most homeowners miss: uneven heating. If some rooms in your Dallas home feel noticeably colder than others, the problem may be an aging single-stage furnace that can’t move air properly anymore, and patching it with higher thermostat settings just runs up the gas bill.
Furnace repair is still the right call in plenty of situations. An igniter, flame sensor, or pressure switch on a 6-year-old furnace is absolutely worth fixing. For most repairs, a good technician will tell you honestly: “This will fix it, here’s the bill, here’s the guarantee window.” If our technician thinks replacement makes more sense for your situation, they’ll say so and show you the numbers side by side.

How to Save on Furnace Replacement in Dallas
Smart ways to reduce your out-of-pocket without cutting corners on safety or quality:
- Get a written, itemized quote and compare, but compare honestly. When comparing quotes, make sure each one lists the same furnace size in BTU, the same AFUE rating, the same brand tier, and the same scope for venting, electrical, and removal. A lower price that omits the permit or uses a smaller furnace isn’t a better deal, it’s a different project.
- Don’t oversize, but don’t undersize either. A furnace that’s too big for your Dallas house cycles on and off constantly, wastes gas, and wears out sooner. A furnace that’s too small runs constantly on cold days and still can’t hit the setpoint. Proper sizing is free if the company does a real Manual J load calculation. At Brandt HVAC Co Dallas, we run that calculation on every replacement, not guesses based on square footage.
- Ask about manufacturer rebates and utility incentives. Atmos Energy and local Dallas-area municipal utilities sometimes run efficiency rebates for high-efficiency furnace installation. We can tell you what’s currently available for your address and subtract it from your quote.
- Time your replacement for the off-season. March and October are typically slower for Dallas HVAC companies. You’ll often have more scheduling flexibility, and that flexibility occasionally translates to better pricing on equipment from distributors. But don’t wait until your furnace is dead, because emergency replacement means less time to consider options.
- Get a free estimate. This one’s simple: call (325) 312-3269 and we’ll come out, size your home, assess your ductwork and venting, and give you a written quote. The estimate is free, and the written price is exactly what you’ll pay. No add-ons later.

Who Is Coming to Your Door?
Here’s where we’re different from most HVAC companies in Dallas, and we’re going to say it plainly because it matters. When you book a furnace replacement with us, you know who is coming before they arrive. We send you the technician’s name and photo in advance. When they ring the bell, they show you a photo ID badge at the door. If anyone shows up who you weren’t told to expect, that visit is on us.
That standard has a name: Threshold Verified. Every Brandt HVAC technician is background-checked and identity-verified before they ever set foot on your property. For a homeowner who’s often home alone, a parent with young children, or an older homeowner, opening the door to a stranger is a genuine concern. We built our company for exactly that person.
Brandt comes from an old word for a firebrand, a fitting name for the work of keeping a home warm. The company was established in 2003 as part of the Threshold Group family of home-service companies. Each location is independently owned and operated. This Dallas location is led by Devin Marlowe, and the person who answers your call is a live person, not a phone tree, 24 hours a day, 7 days a week.
Gas appliances, including furnaces, involve risk. Natural gas leaks, carbon monoxide, and improper venting are real dangers, not hypotheticals. A cracked heat exchanger can leak carbon monoxide into your home, and you can’t see it or smell it. If you suspect a gas leak or smell gas, leave the house and call your gas utility’s emergency line. Do not flip light switches or use anything that could spark. Furnace installation is not a DIY project, and we won’t pretend otherwise. This is skilled trade work with life-safety implications, and it belongs in the hands of a trained professional.
FAQs – Furnace Replacement Cost in Dallas
Is it cheaper to repair or replace a furnace?
For most repairs ($150 – $700 in Dallas), repair is cheaper in the short term. Replacement at $4,200 – $14,000 only makes financial sense when the furnace is over 15 years old, the heat exchanger is cracked, or repairs are stacking up. Our technicians will show you the repair cost and the replacement cost side by side and let you decide, no pressure.
How long does furnace replacement take in Dallas?
A standard same-size furnace swap takes 4 – 8 hours for a two-person crew. If venting changes, ductwork modifications, or electrical work are needed, plan for 1 – 2 days. We’ll tell you the expected timeline in your written quote, and we don’t leave until the furnace is fully tested and running.
What brand of furnace should I buy in Dallas?
Any of the major brands will serve a Dallas home well: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The bigger decision is size and efficiency, not the nameplate. We’ll help you match a brand and model to your home’s heat load and your budget, and we service all of them if you already have a preference.
Can you replace a furnace the same day?
Same-day replacement is possible in many Dallas cases, especially during the off-season, but it’s not something to assume. Emergency replacements are most common during cold snaps in November through February, when demand is highest. Call (325) 312-3269 and a live person will tell you our current scheduling window and whether same-day service is available for your address.
How much does a high-efficiency furnace cost in Dallas?
A 96% AFUE two-stage furnace runs $6,000 – $8,900 installed in Dallas. A 97%+ variable-speed unit runs $8,500 – $14,000. The higher upfront cost typically pays back in lower gas bills over 5 – 10 years, depending on your usage and how long you stay in the home.
Do I need a permit to replace a furnace in Dallas?
Yes. The City of Dallas requires a mechanical permit for residential furnace replacement. We pull the permit and coordinate the inspection as part of the installation. If a company skips this step, you’re taking on liability that no savings is worth.
What is the 365-Day Done Right Promise?
It’s our guarantee on every job: if we didn’t do it right, we make it right. Within 365 days of your furnace replacement, if something we installed fails, we return at no charge. No argument. You’ll have the guarantee in writing, and it states exactly what it covers and for how long. If our work fails inside that window, the second visit is free. That’s the whole promise.
