When a furnace stops working in Carrollton, the window for finding a trustworthy contractor is short — especially once November arrives and every HVAC company in DFW gets slammed with calls. This guide covers the most credible local options, realistic 2026 price ranges, and the questions worth asking before anyone opens your utility closet. Whether you are dealing with a dead igniter or weighing a full system replacement, knowing what fair looks like puts you in a better position from the first phone call.

Best for Transparent, Upfront Pricing
Varsity Zone HVAC
Carrollton homeowners should not have to sit through a two-hour in-home sales presentation just to find out what a furnace repair costs. Varsity Zone HVAC offers free upfront quotes without that drawn-out pitch, and their online scheduling means you are not stuck on hold during a busy stretch. They are a Trane Comfort Specialist based in Frisco and serve Carrollton, The Colony, Plano, and surrounding communities. The detail that separates them from most competitors is the warranty structure: 10 years covering both parts and labor. Most HVAC companies in this market cover parts for a decade but limit labor coverage to one or two years. In practice, that gap matters more than most homeowners realize. If a heat exchanger or inducer motor fails in year four, the part may be free under a standard warranty — but the labor bill to pull and replace it can run $300 to $600 or more, and that comes entirely out of pocket. With Varsity Zone’s warranty, that call in year four costs nothing. Because a significant furnace failure — a cracked heat exchanger, a failed blower motor — often becomes a repair-or-replace decision anyway, that labor protection matters whether the repair holds or the household ends up going with a full system. Financing is also available. Reach the Carrollton team at (972) 402-6948.
Best for Ethics and NATE-Certified Technicians
Advent Air Conditioning
Advent Air Conditioning has operated since 1981 and holds a distinction that is genuinely rare in this market: they were the first HVAC company in North Texas to receive the Better Business Bureau Torch Award for Ethics. Their technicians are NATE-certified and trained across a wide range of equipment brands, which matters when your furnace is something other than the most common make on the shelf. Based in Lewisville, Advent explicitly lists Carrollton among their service cities, making them a solid option for homeowners in the Josey Ranch or Rosemeade areas who want a contractor with a verifiable track record of straight dealing.
Best for Long-Standing Carrollton Roots
Brothers Air Conditioning & Heating
Brothers Air Conditioning & Heating has been family-owned and operating since 1985, with a physical presence in Carrollton itself. They focus on honest service and respect for the home — no upselling you on parts your system does not need. For residents who prefer working with a contractor that has been in the community through multiple building cycles and neighborhood changes, Brothers is a reasonable first call. They appear among the top-rated Carrollton HVAC providers on Yelp as of July 2026.
Best for Same-Day Emergency Service
Medley Heating, Air Conditioning & Plumbing
If the furnace stops on a cold morning and you need someone there the same day, Medley Heating, Air Conditioning & Plumbing is worth calling first. Carrollton-based and consistently ranked at the top of local listings, Medley offers fast quotes and has responded to emergency situations for Carrollton customers. The added plumbing capability means one call handles more than just the HVAC side if something else surfaces during the visit.
What to Expect: 2026 Price Ranges for Furnace and HVAC Work
Repair vs. Replace — Know the Numbers Before You Call
For most routine furnace repairs in the DFW area — a bad igniter, a faulty flame sensor, a failed control board — expect to pay somewhere between $150 and $650, with the midpoint landing around $350 to $450. Labor and diagnostic fees make up a significant portion of that regardless of the part cost, so a $90 igniter can easily become a $350 invoice once the truck rolls.
More serious repairs climb quickly. A failed inducer motor or heat exchanger replacement can push $800 to $1,500 or beyond. If a quote crosses the $2,500 to $4,000 range on a system that is 10 to 12 years old or more, it is worth pricing a full replacement before signing off. A full HVAC system replacement — furnace and air handler plus outdoor unit using existing ductwork — typically runs $8,000 to $16,000 in the DFW market in 2026, with most mid-tier installs landing between $9,000 and $13,000. The 2026 refrigerant transition to R-454B added roughly $500 to $1,000 to new unit costs across the market.
If your ductwork needs replacement alongside the system, add $3,000 to $8,000 to those figures. DFW installations tend to run 15 to 25 percent above the national average — the climate here pushes equipment hard for eight or nine months a year, and contractors price accordingly.
Oncor’s Home Energy Efficiency rebate program offers $400 to $600 back on qualifying high-efficiency equipment for installations completed before November. The federal Section 25C tax credit expired December 31, 2025 and is not available for 2026 purchases.
Before any contractor starts work, verify their Texas Department of Licensing and Regulation (TDLR) license. Texas requires HVAC contractors to hold a TDLR license backed by at least four years of documented experience and proof of insurance. Carrollton falls under standard Texas permitting requirements, and a licensed contractor should pull the appropriate permit for any major installation or replacement — that is not optional, and any company that suggests skipping it is a red flag.
Frequently Asked Questions
How much does furnace repair cost in Carrollton, TX in 2026?
Most furnace repairs in the Carrollton and broader DFW area run between $150 and $650 in 2026, with an average closer to $350 to $450 for a standard service call. More complex repairs involving heat exchangers or inducer motors can reach $800 to $1,500 or more.
How do I verify an HVAC contractor is licensed in Texas?
Check the Texas Department of Licensing and Regulation database before hiring anyone. Texas requires HVAC contractors to be licensed by TDLR with at least four years of recent experience and current proof of insurance — any reputable company will provide their license number without hesitation.
What is the repair-or-replace threshold for a furnace?
A commonly used rule of thumb: if the repair quote exceeds $2,500 to $4,000 on a system more than 10 to 12 years old, get a full replacement quote before committing. At that cost level, the math often favors a new system with a warranty over patching aging equipment.
Does Varsity Zone HVAC serve The Colony and Carrollton?
Yes. Varsity Zone HVAC is based in Frisco and explicitly serves both Carrollton and The Colony, along with Plano, Prosper, Celina, Little Elm, and Aubrey. Carrollton homeowners can reach them at (972) 402-6948 or schedule online.
What should I ask an HVAC company before agreeing to a repair?
Ask for a written estimate before work begins, confirm they are TDLR-licensed, ask how long the labor warranty lasts separately from the parts warranty, and find out whether they will pull a permit for any major work. A company unwilling to answer those questions directly is worth passing on.
