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.
Fast, Reliable Air Duct Repair Across Keller
Air duct repair in Keller typically costs $350 – $900 for a single-system repair call, with multi-zone homes running higher depending on how many branch runs need replacement or re-sealing. That’s the honest range we quote here because your house is probably not like a typical DFW suburb home. Keller’s housing stock runs large: 3,500+ square feet, two stories, multiple air handlers, and duct runs that snake through attics that hit 140°F in August. We know those houses because we’ve been inside hundreds of them. When you call (980) 447-2498, you’ll speak to a live person who can schedule a Keller visit and get you a written price before any work starts.
Why Linden Air Duct Cleaning Is Keller’s Preferred Air Duct Repair Company
Homeowners around Keller call us for one reason that keeps repeating: we show up with a name, a face, and a written price. Before your tech arrives, you get their name and photo sent to you. At the door, they show a photo ID badge. Every tech is background-checked and identity-verified under the Threshold Standard we’ve operated to since 2004. No anonymous van pulls up outside your house. That matters in Keller, where a lot of our customers are home alone during the day, or have young kids, or simply don’t like the idea of a stranger walking through their upstairs hallway without knowing exactly who they are.
We’ve worked in Keller long enough to know its specific failure patterns: flex duct corrugating near elbows, mastic seals crumbling at duct boots, and zoned systems where only one air handler gets attention while the other two quietly pack debris. Marcus Veale, who leads our team, insists on camera inspection before quoting repair work. If we can’t show you the problem, we don’t ask you to pay for a fix. That’s not a sales line. That’s how we’ve built our reputation in this city.
Air Duct Replacement in Keller
Air Duct Replacement in Keller is a job we recommend when flex duct has failed beyond repair: liner torn through, branch runs collapsed, or mastic seals so far gone that re-sealing would mean chasing failures across a 25-year-old system. In Keller’s 1995 – 2008 subdivisions, that’s more common than homeowners expect. A typical single-branch replacement runs $220 – $450 in this market. A full supply-and-return replacement for one air handler on a 3,500 sq ft Keller home generally lands between $1,200 and $2,800, depending on run lengths and how many boots need reconnection. We put that number in writing before we start.
Whole-System Replacement for Keller’s Attic Flex Runs
When we replace ductwork in Keller, we’re usually working in an attic that’s been baking the original flex for 15 – 30 years. The outer jacket gets brittle, the inner liner corrugates, and airflow drops even when the HVAC unit tests fine. Our crews use Rotobrush and Nikro equipment for source removal, then install properly sized flex with sealed, insulated boots. We don’t reuse old mastic. We don’t patch what should be replaced.
Partial Replacement When Only One Zone Has Failed
Plenty of Keller homes have three systems, and only one zone is failing. You don’t need a whole-house replacement because the upstairs return has collapsed. We scope what failed, replace those runs, reconnect and reseal the boots, and leave the healthy ducts alone. You pay for the repair, not a sales pitch.
Ductwork Repair in Keller
Ductwork Repair in Keller almost always starts with the same question: is the airflow problem coming from the duct, the air handler, or the return side? In this city’s large two-stories, that question is harder than it sounds. A single repair visit in Keller typically runs $180 – $520 for sealing boots, reconnecting separated branch runs, and patching small liner tears. When multiple zones need work, the job scales per system, not per vent. We price per system because your house may have three of them, and the work is not the same across all three. You get one flat price per system, agreed before anything starts.
Sealing and Boot Reconnection
Keller’s attic heat is brutal on duct boots. The mastic dries out, cracks, and pulls away from the sheetrock or plenum. Conditioned air dumps into the attic while attic dust and fiberglass get pulled into the return path. We remove the old mastic, re-seat the boot, apply fresh sealant, and inspection-camera the result before we call it done.
Flex Liner Repair Near Elbows
The most common Keller failure we see is the inner liner of flex duct corrugating near elbows. The duct looks fine from the outside. Inside, it’s partially collapsed and choked with debris. We identify this with a camera, not guesswork. Then we either replace the affected run or, if the liner is intact enough, perform source removal and re-support the run so it doesn’t re-collapse.
Trusted Brands We Service in Keller
Keller homes came with a mix of builder-grade and upgraded ductwork, and we service all of it. Our techs work with professional equipment from Rotobrush and Nikro, and we’re familiar with air-quality products from Guardsman and Abatement Technologies when a repair calls for filtration or antimicrobial treatment. Because Keller’s housing stock is so uniform in age, we keep common parts and fittings in our vehicles: flex duct in standard diameters, boot connectors, mastic, and plenum repair materials. That means fewer return trips and faster turnaround when we identify a failed run in your attic. We come prepared for Keller’s specific homes, not a generic service call.
Common Air Duct Repair Problems We See in Keller Homes
- Collapsed flex liner near elbows off the plenum. Keller’s 1995 – 2008 builders commonly used unlined sheet-metal plenums connected to flexible branches. After 20-plus years of attic heat, the inner liner corrugates and chokes airflow. Homeowners often think the HVAC unit is dying when the duct was the problem all along.
- Failed mastic seals at duct boots and branch takeoffs. Attic temperatures in Keller routinely exceed 140°F from May through October. Mastic doesn’t survive that forever. When seals crack, you’re paying to cool the attic and pulling dust into the return side at the same time.
- Multi-zone homes where one system gets all the attention. Keller has many houses with three air handlers. The upstairs gets serviced, the downstairs is forgotten, and the return side of the forgotten system packs debris deeper each cooling season. Repairing one zone doesn’t fix a house where another zone is starving for airflow.
- Debris load from Keller’s cedar fever cycle. From December through February, Ashe juniper pollen settles into return grilles and filter housings. Spring brings oak and elm surges. In a house that runs AC near-continuously from May to October, that debris works into the duct liner and compacts at restrictions. When we open a duct boot in Keller, we can usually tell what season the leak started by what’s packed inside.
Pricing for Air Duct Repair in Keller, TX
What you’ll pay for air duct repair in Keller depends on how many systems your house has and what the camera shows. A single-system repair: $180 – $520. A branch-run replacement on a two-story: $220 – $450. A full duct replacement for one air handler of a 3,500 sq ft home: $1,200 – $2,800. Three-system homes run higher because three systems mean three times the linear footage, three plenums, and three sets of boots. We give you one flat price per system before work starts. If the repair doesn’t hold, our 365-Day Done Right Promise means we come back and make it right, in writing, at no charge. Call (980) 447-2498 for a free estimate.

FAQs About Air Duct Repair in Keller
Keller duct repair costs more because the houses are bigger, the runs are longer, and most homes have multiple systems. A 3,500 sq ft two-story in Keller may have three air handlers and hundreds of linear feet of flex duct in 140°F+ attics. That’s more labor, more materials, and more time per system than a 1,800 sq ft single-story in a neighboring town. You’re not paying more for the same job; you’re paying for a physically larger job. Call (980) 447-2498 and we’ll give you a specific price for your home’s systems.
The only way to know is a camera inspection. We run a scope through your supply and return runs. If the liner is torn, collapsed, or corrugated shut near an elbow, that’s a mechanical failure that cleaning won’t fix. If the liner is intact but packed with debris, it’s a cleaning problem. We don’t quote repair work without showing you what the camera sees. In Keller’s 2000s-era homes, we often find both: debris packed into a section of liner that’s already partially collapsed.
Keller’s building boom happened between the mid-1990s and late 2000s. Those homes are now 15 – 30 years old. The flex duct installed during construction has been through 15 – 30 North Texas summers of 140 – 150°F attic temperatures. Mastic seals dry and crack. Boot connections loosen. Flex liners corrugate and collapse near elbows. That’s the age of failure for builder-grade ductwork, and most of Keller is now right in that window. Cleaning removes debris. Repair fixes the structure that caused the debris to accumulate in the first place.
Yes. Keller sits in the cedar fever corridor, and Ashe juniper pollen from December through February is relentless. It settles into return grilles and filter housings, then gets drawn into the duct system. When your AC runs from May through October, that pollen and the spring oak/elm load behind it keeps recirculating and compacting. If you have a return-side leak, which is common in Keller’s aging mastic seals, you’re also pulling attic dust and fiberglass into the system. Repairing the leak stops the intake. Cleaning removes what’s already inside. Call (980) 447-2498 for a camera inspection to see which problem your house has.
You should expect before-and-after camera footage of every run that was repaired or replaced. You should expect a written description of what failed, what was done, and what materials were used.

Marcus Veale’s standard on every Keller job is simple: the customer gets proof the work happened, proof of what it cost, and a written promise that it holds. That’s what the Threshold Standard has meant since 2004.
