AfterFurnace Replacement in Dallas, TX
Furnace replacement in Dallas typically runs between $3,800 and $7,500 for a standard single-family home, depending on furnace size, efficiency rating, and whether ductwork needs modification. Most replacements take one full day, and Dalton Heating & Air Dallas provides a written price before any work begins so you know the exact number before we touch a single component. If your furnace is over 15 years old, needs a repair that costs more than half its remaining value, or has a cracked heat exchanger, replacement is usually the smarter financial decision.
We’re a Garrison Partners company held to The Garrison Standard since 2003, which means every replacement includes a written price up front, a written guarantee on the work, and a 365-Day Done Right Promise. Call (254) 280-5320 and you’ll reach a live person, not a voicemail queue. We also handle broader Heating & Furnace in Dallas work, including repairs, maintenance, and heat pump installation.
When You Need Furnace Replacement
Not every furnace problem means replacement. But these are the situations where we tell Dallas homeowners to stop repairing and start replacing:
- Your furnace is 15 years or older. Most furnaces in Dallas last 15 to 20 years. Once you’re past the 15-year mark, every repair is money going into a system that’s nearing the end of its service life anyway.
- The heat exchanger is cracked. This is the part that separates combustion gases from the air you breathe. A cracked heat exchanger is a carbon monoxide risk and should trigger immediate replacement, not a patch job.
- Repair costs are stacking up. If you’ve spent $600+ on repairs in the last two years and the furnace is over 12 years old, you’re on the wrong side of the cost curve. The rule of thumb we use: if a repair costs more than 40 to 50 percent of a new unit, replace it.
- Your heating bills keep climbing while comfort drops. Older furnaces run at 70 to 80 percent efficiency. A new high-efficiency unit runs at 90 to 96 percent. In Dallas, where heating season is shorter but cold snaps hit hard, that efficiency gap translates to real money each winter.
- Uneven heating or constant cycling. Rooms that never warm up, a furnace that short-cycles on and off every few minutes, or a blower that runs constantly can signal a unit that’s no longer sized or functioning correctly.
- Yellow burner flame or soot buildup. A healthy gas furnace burns blue. Yellow flame or black soot around the burner access panel means incomplete combustion, which wastes fuel and can put carbon monoxide into your home.
Our Furnace Replacement Process
Replacement is not the same job as repair. It requires load calculation, sizing decisions, sometimes ductwork adjustments, and exact installation work. Here’s how we run it:
- On-site assessment and load calculation. We measure your home’s square footage, ceiling height, window orientation, insulation levels, and existing ductwork. Then we run a Manual J load calculation to determine the correct furnace size. Guessing at sizing is how you get a furnace that short-cycles or never satisfies the thermostat.
- Written quote with equipment options. You get a written price that itemizes the furnace model, efficiency rating, labor, and any ductwork or venting changes. That price does not change when the crew arrives. It’s The Garrison Standard: price in writing before any work starts, every job, no exceptions.
- Equipment selection across major brands. We service and install nine major residential HVAC brands, including Trane, Lennox, Goodman, and Rheem. We’ll recommend what fits your budget and home, not what’s sitting in a warehouse. You decide before we order anything.
- Removal and installation. We disconnect and remove the old furnace, set the new unit, connect gas and electrical supply, tie in the venting, and test the full system. Our technicians are background-checked, uniformed, and factory-trained. You’ll know who’s coming before they arrive.
- System startup and combustion testing. We verify gas pressure, airflow, temperature rise, and carbon monoxide output. At the end of the install, the furnace is running at manufacturer spec, not just “running.”
- Cleanup and walkthrough. We leave the site clean, walk you through what was done, and hand you the written guarantee. If anything fails within the guarantee period, we return at no charge. That’s the 365-Day Done Right Promise, and it’s in writing.
Furnace Replacement Pricing in Dallas
Here’s what furnace replacement costs in Dallas, based on the work we do across the metro:
| Furnace Type | Typical Installed Cost | Who It Fits |
|---|---|---|
| Standard efficiency (80% AFUE), 60,000 – 80,000 BTU | $3,800 – $5,200 | Smaller homes, mild winter use, budget-conscious replacement |
| High efficiency (92 – 96% AFUE), 60,000 – 100,000 BTU | $5,500 – $7,500 | Most Dallas homes, especially if you plan to stay 5+ years |
| Two-stage or variable-speed high efficiency | $6,800 – $9,500 | Larger homes, comfort-focused homeowners, homes with zoning |
What moves the price: furnace size (BTU output), efficiency rating (80 percent vs. 96 percent AFUE), brand (Goodman runs lower than Trane or Lennox on average), whether the venting needs conversion for high-efficiency, and whether ductwork needs sealing or modification. A straightforward swap in a home with good ductwork stays in the lower ranges. A 40-year-old house in Lakewood with original ducts and an old gravity vent setup will run higher.
We provide free estimates on every replacement, and the quote is in writing before you commit to anything. Call (254) 280-5320 and we’ll schedule an assessment.
Furnace Brands We Install
Dalton Heating & Air Dallas is factory-trained to service and install nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For replacements specifically, we often recommend Trane for long-haul reliability and strong warranty coverage, Lennox for high-efficiency performance in cold snaps, and Goodman for homeowners who want a solid unit without paying for a premium name. We’ll lay out the trade-offs in plain terms so you can decide with your budget and your house in mind, not marketing brochures.
Furnace Replacement vs. Repair: How to Decide
The math is straightforward. Take the repair cost and multiply it by the age of your furnace. If your furnace is 14 years old and the repair quote is $600, you’re looking at $8,400 in accumulated age-adjusted cost. A new Goodman 80-percent furnace installed runs $3,800 to $4,800. You’re past the tipping point. On the other hand, a six-year-old furnace with a bad igniter that costs $200 to fix is a repair, not a replacement. We’ll give you the straight answer either way, because the written quote tells you the real numbers before you decide.
What Happens to Your Old Furnace
We haul away the old unit as part of the replacement. That includes disconnect, removal of the old furnace, and responsible disposal. We don’t leave the old furnace sitting in your yard or expect you to drag it to the curb. The site is clean when we leave, full stop.
FAQs – Furnace Replacement
How much does furnace replacement cost in Dallas?

Is it cheaper to repair or replace a furnace?
It’s cheaper to repair if your furnace is under 12 years old and the repair costs less than 40 percent of a new unit, but replacement wins when the furnace is over 15, the heat exchanger is cracked, or repair totals exceed half of replacement cost. We’ll show you the numbers for both options in writing before you commit.
Can you replace my furnace same day?
In most cases, yes, if the furnace is in stock at a local supplier and the load calculation confirms the same size unit fits.
