AfterHow Much Does Furnace Replacement Cost in Carrollton?
Furnace replacement in Carrollton typically runs between $3,500 and $7,500 for a full swap, including removal of the old unit, the new furnace, and standard venting and electrical connections. Most single-family homes land in the $4,500 to $6,000 range. Your written estimate sets the final price, and we give that estimate free.
That number moves up or down based on the size of your home, the efficiency rating you choose, and how much of the existing ductwork and flue can be reused. If you’re weighing a repair against a replacement, a furnace repair in Carrollton usually costs $150 to $700, which gives you a clear line to compare against.

Furnace Replacement Cost Breakdown (2026)
Here’s how a typical furnace replacement in Carrollton breaks down. These are estimated ranges for the Carrollton market in 2026, not quotes. The written estimate you receive is what actually sets your price.
| Line Item | Typical Estimated Range |
|---|---|
| Standard replacement furnace (80% efficiency, common sizes) | $1,800 – $3,200 |
| High-efficiency furnace (90%+ AFUE) | $2,800 – $4,800 |
| Labor and installation | $1,200 – $2,200 |
| Removal and disposal of the old unit | $100 – $300 |
| Flue or venting modifications | $200 – $700 |
| Ductwork and plenum adjustments | $300 – $900 |
| Full job, typical total | $3,500 – $7,500 |
What pushes a furnace replacement toward the top of that range? High-efficiency equipment costs more up front than a standard 80% furnace. Homes with tight mechanical closets, unusual venting runs, or ductwork that needs rework add labor. So does a size upgrade, which happens when the original furnace was undersized for the square footage. On the other side, a straight swap where the old unit comes out and a like-sized one goes in with the same flue and plenum keeps the job near the bottom of the range.
One thing worth understanding about Carrollton: our mild winters mean a furnace here runs far fewer hours than one up north, which is why a lot of homes have an 80% furnace rather than the highest-efficiency model. That’s usually the right call financially. High-efficiency equipment pays back faster in cold climates than it does here, so we’ll tell you plainly when a standard furnace is the better value for your house.
What Affects Furnace Replacement Pricing in Carrollton
- Furnace size and capacity. A furnace has to be matched to your home’s square footage and heat load. A larger home in a Carrollton neighborhood like Castle Hills or Rosemeade needs more capacity, and equipment price steps up with size. Getting the size wrong in either direction hurts efficiency and comfort, so we size it properly rather than matching whatever was there before.
- Efficiency rating. An 80% furnace and a 90%+ furnace are different price tiers. In Carrollton’s climate, the efficiency difference shows up less in monthly bills than it would in a colder market, so the cheaper unit is often the sensible pick. We’ll walk you through the math instead of pushing the premium model.
- Brand and parts availability. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Prices vary between these manufacturers, and because we’re not tied to one brand, we can recommend based on what fits your home and budget rather than what pays us the most.
- Venting and flue condition. A high-efficiency furnace often vents differently than a standard one, which can mean new venting and added cost. If your existing flue is in good shape and compatible, the job stays simpler.
- Ductwork and plenum work. If the new furnace is a different size or orientation than the old one, the plenum and nearby duct connections need adjusting. Homes with older or oddly routed ductwork sometimes need more of this than expected.
- Access and location. A furnace in a tight closet, attic, or crawl space takes more labor to swap than one in an open garage or utility room. Access affects the labor line more than anything else on the estimate.
How to Save on Furnace Replacement
There’s no magic discount on a furnace, but a few practical moves keep the number down.
- Don’t replace too early. If your furnace is still repairable, a repair in the $150 to $700 range usually beats a $4,500 replacement. Get an honest repair-or-replace read before you commit to a new unit.
- Match efficiency to your climate. Carrollton’s mild winters mean the payback on a premium high-efficiency furnace is slower than you might expect. A standard furnace is often the better value here, and we’ll tell you when it is.
- Reuse what’s serviceable. If your flue, plenum, and ductwork are in good shape, keeping a like-sized replacement avoids unnecessary rework. Ask whether the existing venting can stay.
- Get more than one written estimate. Compare line items, not just totals. A low total that skips necessary venting or duct work isn’t a real saving.
- Ask what’s included. Removal, disposal, and startup should be spelled out. Estimates are free here, so there’s no reason to sign anything before you’ve seen the full picture. Call (855) 759-1429 for yours.
Repair or Replace? The Honest Answer
The rule of thumb most homeowners use: if a repair costs a big fraction of a new furnace and the unit is old, replace. A $600 repair on a 20-year-old furnace rarely makes sense. That same $600 on a 6-year-old unit usually does.
Because we handle both furnace repair and furnace replacement with the same team, the recommendation you get isn’t steered toward a sale. We diagnose the system, tell you what the actual problem is, and lay out both paths. If a repair gets you several more seasons, we’ll say so. If it won’t, we’ll say that too. That’s the whole point of a brand-neutral approach: the right fix is decided by your system’s condition, not by which manufacturer we’d rather sell.
What Happens When You Call
When you call, we ask about your furnace’s age, brand, and symptoms, then set up a visit for a free estimate. A technician inspects the unit, confirms the size and venting needs, and gives you a written estimate with the equipment, labor, and any venting or ductwork spelled out. There’s no diagnostic fee and no trip charge on the estimate. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday, and we’re closed on Saturday.
Wondering whether the same team handles your air conditioning too? We install AC as well, so a single visit can cover both systems and you don’t need separate contractors for heating and cooling.

Safety: Why Furnace Work Isn’t a DIY Job
A gas furnace involves a gas line, a heat exchanger, and a flue that carries combustion byproducts out of your home. A cracked heat exchanger or a blocked flue can let carbon monoxide into living space, and that’s a genuine health risk, not a hypothetical one. We don’t recommend homeowners open gas connections or tamper with venting. If you smell gas or your carbon monoxide alarm sounds, leave the house and call from outside first.
What you can do safely: change the filter regularly, keep the area around the furnace clear, and have the system checked if you notice unusual smells, soot, or a yellow rather than blue flame. Beyond that, gas and venting work belongs with a trained technician. We’re state-licensed and insured, and every furnace replacement is done by professionals who work on these systems daily.
Does the Brand of Furnace I Choose Matter?
Less than most people think, and more than a single-brand dealer will tell you. Carrollton AC Repair works on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’re familiar with the equipment and parts across the board. That means we can recommend the furnace that fits your home and your budget instead of steering you to one manufacturer. When a dealer only sells one brand, every problem looks like a reason to buy that brand. We don’t have that bias. The brand matters mainly for parts availability and how the unit integrates with the rest of your system, and we’ll explain that trade-off in plain terms.
How Long Does a Furnace Replacement Take?
A straightforward furnace replacement typically takes a full day, sometimes less if the swap is simple and the venting is unchanged. Jobs that involve new venting, ductwork adjustments, or tight access can run into a second day. We’ll give you a realistic time frame with the estimate so you can plan around it.

- Jeff Thompson"New system install, two days, and they were careful with the floors and the attic access the entire time. Registered the warranty for me and emailed the paperwork."
