When a furnace stops working in Aubrey, you have a real problem — North Texas winters are short but they can push overnight lows into the 20s, and a failed heat exchanger or igniter is not something you want to diagnose yourself.

This guide covers the credentialed options, honest price ranges for 2026, and the questions worth asking before anyone touches your equipment.

Best for Local Roots: Air-Care Texas
A contractor with a physical Aubrey address
Air-Care Texas has been operating since 1987 and maintains a listed address at 5025 US 377 in Aubrey, which matters when you want someone who understands the housing stock in subdivisions like Sandbrock Ranch and Arrowbrooke — neighborhoods built fast over the last decade with equipment that is now hitting its first major service cycles. New customers receive 10 percent off service and repair calls, and the company advertises a 10-year parts and labor warranty option, which is worth asking about specifically when you call. For straightforward furnace diagnostics, igniter replacements, or heat exchanger inspections on a standard gas forced-air system, this kind of long-tenured local shop is often the most efficient call.
Best for Combined Trades: Strittmatter Plumbing, Heating & AC
When your furnace repair is part of a bigger project
Strittmatter has held NATE-Certified technicians since 1980 and has served Denton County families for more than four decades. NATE certification matters because it is the industry’s most recognized third-party credential for HVAC technicians — it is not a manufacturer badge or a self-reported rating. If your furnace repair is connected to a larger renovation, a new construction project in one of Aubrey’s fast-growing developments, or a situation where both plumbing and heating lines run through the same mechanical room, having a single licensed contractor handle both trades reduces coordination headaches and liability questions.
Best for Accountability and Transparency: Milestone Electric, A/C, & Plumbing
A+ BBB rating in a market where that still means something
Milestone has been family-owned and operating in North Texas since 2004 and carries an A+ rating from the Better Business Bureau. For homeowners who have been burned before by vague invoices or technicians who upsell without explanation, a BBB-accredited company with that rating has at minimum agreed to respond to complaints through a formal process. Milestone covers Aubrey as part of its broader North Dallas service area. If you are dealing with a furnace issue that involves a major component like a secondary heat exchanger or a variable-speed blower motor, the kind of repair where a second opinion has real dollar value, Milestone is a reasonable call for that estimate.
Best for Indoor Air Quality Alongside Furnace Work: Eric’s Home Services
Veteran-owned, licensed, and same-day in most cases
Eric’s Home Services is veteran-owned, carries Texas HVAC contractor license TACLA87910C, and dispatches same-day for most Aubrey calls. You can verify that license number directly through the Texas Department of Licensing and Regulation website before scheduling — TDLR’s public lookup takes about 30 seconds and confirms whether a contractor is active and in good standing, which is the single most important check any Aubrey homeowner can do before letting someone work on a gas appliance. Eric’s specialty focus on indoor air quality — NADCA-method duct cleaning, UV-C purification, whole-home dehumidifiers, HEPA filtration — makes them a useful call if your furnace issue is accompanied by air quality concerns, which is common in tightly built newer homes in this part of Denton County.
Best for the Aubrey-Little Elm Corridor: Legend Air
Positioned specifically for this stretch of 380 and beyond
Legend Air is a licensed HVAC company that explicitly targets Aubrey, Little Elm, Frisco, and McKinney — the corridor most Aubrey residents actually move through for work and errands. That geographic focus often means faster response windows and technicians who are already running routes through the area rather than driving in from Dallas proper. Services include furnace repair and service, duct cleaning, and maintenance agreements. If you are newer to Aubrey and do not yet have an established HVAC relationship, Legend Air is worth including in your quote comparison.
Frequently Asked Questions
What does furnace repair cost in Aubrey, TX in 2026?
For most common repairs — igniter replacement, flame sensor cleaning, pressure switch, or blower motor — expect to pay between $150 and $650 in parts and labor in the DFW area in 2026. A full furnace replacement in Denton County, including installation, typically runs $2,800 to $5,500 for the furnace alone, or $8,000 to $16,000 if you are replacing the full system including the air conditioner and air handler. These are estimates; get itemized written quotes from at least three contractors before committing.
Do I need a permit to replace a furnace in Aubrey, TX?
Yes, in most cases. The City of Aubrey and Denton County require mechanical permits for furnace replacements, and a licensed contractor should pull that permit on your behalf. If a contractor tells you a permit is unnecessary for a full system swap, that is a red flag. Permitted work is inspected, which protects you if you sell the home.
Is the federal HVAC tax credit still available in 2026?
No. The Section 25C federal tax credit for high-efficiency HVAC equipment expired on December 31, 2025, and is not available for equipment placed in service in 2026. However, if you are in CoServ territory — which covers much of Aubrey — CoServ offers a $400 rebate for qualifying central AC systems at SEER2 16 or higher, and $500 for qualifying heat pumps. Ask your contractor to confirm the equipment meets those thresholds before installation.
How do I know if an HVAC contractor is licensed in Texas?
Search the contractor’s name or license number through the Texas Department of Licensing and Regulation public database at tdlr.texas.gov. A valid Texas HVAC contractor license is required by state law for anyone charging to install, repair, or replace HVAC equipment. If a company cannot provide a license number, do not hire them for gas furnace work.
What should a furnace repair quote include?
A legitimate quote should itemize the diagnostic fee, each part being replaced with its part number or description, labor cost, and any warranty terms in writing. A lump-sum total with no breakdown is a red flag — reputable contractors itemize because they have nothing to hide. Get at least three written quotes before approving any repair over $300, and compare not just the total but the warranty each company stands behind.
