Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Air Duct Cleaning in Flower Mound for Trane systems typically runs $380-$780 for a single system and $890-$1,650 for a full three-system home, with written pricing delivered before any panel comes off. We’re an independent Lewisville-based crew, not a Trane-authorized dealer, and we’ve worked on Trane residential systems in Flower Mound’s subdivisions since those homes were new. Call (940) 240-8552 for a free written estimate.
Why Flower Mound Residents Choose Us for Trane Service
We’ve been inside the ductwork of Flower Mound homes since the first master-planned subdivisions were finishing out in the late 1990s. Tomas Reyes, our owner, picked up his HVAC fundamentals at Manhattan’s Apex Technical School and spent the next two-plus decades working inside ductwork across North Texas. He and our crew have run jobs in Flower Mound for years, including plenty of large homes near the Estates of Montalcino and Lakeside, where the flex duct tends to sag and accumulate debris in ways that don’t show up until you put a camera inside.
We know how Trane equipment ages here. The Trane sales & service work we do covers XR series split systems, XR80 and XR90 gas furnaces with cased coils, XB and XR outdoor condenser units, and XV series variable-speed air handlers. We stock genuine Trane OEM filter racks, mastic, and flex-duct fittings for when the original components are Trane-specific, and we source quality aftermarket materials for general flex duct and insulation that match or exceed original spec.
Every job starts with a written price under Haven Standard Clause 1. Every duct run is photographed before and after. Our 365-Day Done Right Promise is backed in writing, not stated and forgotten. And our equipment roster, Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman, is named on every estimate so you can verify what we’re running before you agree to anything.
Common Trane Air Duct Cleaning Problems We Solve in Flower Mound

- Baked-on coil dust in attic air handlers. Trane cased coils mounted in Flower Mound’s attic air handlers collect dust through the long cooling season, then that dust bakes onto the fins when attic temperatures hit 130-140°F in July and August. The result is restricted airflow and a compressor that runs longer than it should. We clean the evaporator coil and blower assembly in place when possible, documenting the before condition with photos.
- Detached flex-duct liners at register boots. Trane XR series systems in 2000s-era Flower Mound homes were paired with first-generation flex duct whose inner liner has now separated after two decades of attic heat cycling. Conditioned air dumps into the attic instead of the bedroom. We find this regularly in the Estates of Montalcino and similar subdivisions. We reattach, mastic-seal, and photograph the repair.
- Undersized or disconnected return chases pulling attic debris. Trane air handlers in Flower Mound’s large homes frequently draw return air through chases that were never properly sealed or have separated over time. Attic dust, insulation fibers, and pollen get pulled straight into the blower wheel and evaporator coil. We video-inspect the return path and seal what we find.
- Cracked plenum mastic joints after thermal cycling. After 15-25 years of expanding and contracting through Flower Mound’s extreme attic temperature swings, Trane plenum mastic joints crack and leak. This lowers static pressure at the coil and allows unfiltered return air to bypass the filter entirely. We scrape, reseal, and pressure-test.
- Three-system homes where only one system was ever touched. Because nearly every Flower Mound home from the 1993-2008 boom has two or three separate Trane systems, previous “duct cleaning” visits often addressed just the main system and ignored the second and third attic air handlers. We check every system, every time, and we put it in writing.
Before
AfterTrane Service in Flower Mound: What Local Conditions Mean for Your Equipment
Flower Mound sits in the Cross Timbers ecological zone, where post oak, cedar elm, and mountain cedar produce pollen loads that don’t let up. Cedar fever peaks December through February, oak and elm follow through spring, and the AC runs nearly continuously from April through October. That’s seven or more months of pulling allergen-laden air through aging flex duct, plus Grapevine Lake’s localized humidity elevating mold-spore risk when condensation forms inside attic runs.
Here’s what this means for Trane owners specifically. A 4,000-square-foot home in the Estates of Montalcino with three Trane systems has roughly three times the linear duct footage of a 1,800-square-foot home in older Lewisville. Each system has its own plenum, its own flex-duct network, its own evaporator coil, and its own set of mastic joints that have been thermal-cycling for 20 years. When we arrive for a “duct cleaning,” we’re often looking at a full-day job covering three independent attic air handlers, not a two-hour vacuum session. Homeowners are routinely surprised that the second and third systems were never touched by the previous company. We photograph what’s in every run before and after, so you can see exactly what changed and for how much. Here’s the before photo. Now let’s talk about what happens next.
Trane Models & Products We Service in Flower Mound

We service Trane XR series split systems (XR13, XR14, XR15), XR80 and XR90 gas furnaces with cased coils, XB and XR outdoor condenser units paired with attic air handlers, and XV series variable-speed air handlers. These are the systems we find in Flower Mound’s 1990s-2000s housing stock, and we carry the OEM filter racks, mastic, and flex-duct fittings to match Trane-specific components when needed.
For general flex duct, mastic sealant, and insulation, we use aftermarket materials that meet or exceed original specifications. When a Trane coil or heat exchanger is genuinely failing, we tell you plainly. On 20-year-old Trane equipment in Flower Mound, a cleaning plus duct sealing is usually the right call. We’ll say so if it is not.
Our equipment includes Rotobrush agitation systems, Nikro and Abatement Technologies negative-pressure extractors, and Honeywell, Aprilaire, and Guardsman air quality components. You can look up every brand independently.

FAQs - Trane Air Duct Cleaning in Flower Mound
No. Brand doesn’t determine cleaning frequency; local conditions do. Flower Mound’s heavy pollen seasons, long cooling season, and 20-year-old flex-duct infrastructure mean any system here accumulates debris faster than in milder climates, which is why our Dryer Vent Cleaning in Flower Mound also addresses built-up lint and debris. We recommend inspection every 3-5 years for homes built during the 1993-2008 boom. Call (940) 240-8552 to schedule.
Yes. Each system has its own duct network, plenum, and air handler. Cleaning one does not clean the others. We quote each system separately in writing, and we photograph every run before and after. Many Flower Mound homeowners discover their previous “whole house” cleaning only addressed the main system. Call (940) 240-8552 for a three-system estimate.
Usually, yes. We access the coil through the plenum or filter rack, clean it in place with foaming cleaner and low-pressure rinse, and photograph the result. If the coil is too degraded for safe in-place cleaning, we’ll tell you before we start and give you a written price for the additional work.
No. Professional duct cleaning by an independent service provider does not void manufacturer warranties. We are not affiliated with Trane, and we do not perform warranty work on their behalf. For warranty claims, contact Trane directly or an authorized dealer. We handle the cleaning, sealing, and repair of the duct system itself.
Mountain cedar pollen peaks December through February, and it is fine enough to pass through standard filters and accumulate in duct walls and on coils. When the AC starts up in April, that pollen gets redistributed. Cleaning before the cooling season starts removes the buildup and reduces what gets blown through the house. Call (940) 240-8552 to book pre-season service.
