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.

AfterFast, Reliable Air Duct Repair Across Sunnyvale
Air duct repair in Sunnyvale usually means one of two things: a collapsed flex run in a 1960s ranch home, or a remodel that just exposed 60-year-old ductwork to a cloud of drywall dust. Either way, you’ll want a crew that knows these homes before the drywall goes back up. Our techs work in Lakewood, Cherry Chase, and Borregas every week, so we know what a 1962 attic flex connector looks like when it’s been crushed flat behind new cabinets. We’re Linden Air Duct Cleaning, and for reliable Air Duct Repair in this part of Texas, call us at (980) 447-2498 for a straight answer and a written price before any work begins.
Why Linden Air Duct Cleaning Is Sunnyvale’s Preferred Air Duct Repair Company
Sunnyvale homeowners don’t have time for a company that has to figure out the area on the day of the job. We’ve worked the ranch tracts here long enough to know that a 1958 Lakewood split-level and a 1972 Borregas single-story need different approaches, because the ductwork was never installed the same way twice. Marcus Veale, who runs our crews, insists on that kind of local knowledge. When a Cherry Chase remodeler calls and says the soffit just came down exposing original duct board, our tech knows what he’s walking into before he pulls up.
Every technician who arrives at a Sunnyvale home is background-checked, identity-verified, and arrives in a clean, marked uniform. You get the tech’s name and photo before the visit, and a photo ID badge is shown at the door. That’s the Threshold Standard, and we’ve held to it since 2004. It matters more out here, where long driveways and quiet streets mean you’re often home alone when the service van shows up.
We back every repair with a written guarantee. If the repair doesn’t hold, we come back at no charge. That’s not a promotion. It’s a standing commitment on every job we do in Sunnyvale.
Air Duct Replacement in Sunnyvale
Air Duct Replacement in Sunnyvale is what happens when a 1960s flex run has been crushed, split, or eaten through and patching it would just buy you another season. In these ranch homes, original duct runs often sit in unconditioned attics where decades of Texas heat and that morning moisture from the east side’s open land have done real damage. Sunnyvale homeowners call us when a remodel exposes ductwork so far gone that replacing it is the only honest fix.
When Replacement Beats Repair
A collapsed flex connector behind a new kitchen soffit isn’t repairable in any meaningful way. Neither is a supply trunk with rust-through along the bottom seam. We tell homeowners the truth: if more than about a third of the run is compromised, replacement costs less long-term than chasing leaks every year.
What Replacement Costs in Sunnyvale
For a typical single-run flex replacement in a Sunnyvale ranch home, you’re looking at $700 to $1,500 depending on run length and attic access. Full-system replacement runs more, often $3,000 to $6,000, but that’s the whole duct system, not one leg. We give you a written price before any work starts, and you approve it before we open a single access panel.
Ductwork Repair in Sunnyvale
Ductwork Repair in Sunnyvale covers the fixable stuff: split seams, disconnected collars, crushed flex runs that still have integrity in the liner, and duct board joints that have pulled apart over 60 years of thermal cycling. A lot of what we do on the east side is prep work for a sale. Homeowners get a pre-listing inspection, the inspector flags the ducts, and we come in before the photographer arrives.
Sealing and Re-Taping
Most older ranch homes in Sunnyvale have sheet-metal or early flex systems put together with whatever tape and mastic the original installer had on hand. That’s gone brittle by now. We re-tape with modern UL-listed materials, re-seal with mastic, and test the run for negative pressure leaks.
Reconnecting Crushed Runs
We see this constantly in Cherry Chase and Lakewood: a remodel crew moving a wall or adding a beam has crushed a flex run or knocked a takeoff loose. Our techs rebuild the connection, re-hang the run properly, and run agitation tools through the supply and return before sealing it back up.
Trusted Brands We Service in Sunnyvale
Sunnyvale homes are a mix of original equipment and whatever a previous owner installed in a hurry. We work with professional-grade systems from Rotobrush and Nikro on the cleaning side, and we stock commonly needed repair parts for Aprilaire and Abatement Technologies components that show up in these ranch homes. If your system has a Guardsman-style filter cabinet or a Honeywell bypass setup, our techs service those too. We keep the parts that actually fail on 1960s flex systems, so we don’t have to order from a warehouse while your remodel sits on hold.
Common Air Duct Repair Problems We See in Sunnyvale Homes
- Dust loading from unpaved roads: Homes on the east side near open land pull dust and pollen into attic ductwork that was never sealed to today’s standards. Old duct board and flex joints load up fast, then the negative pressure from a blower motor spreads that particulate through every room.
- Wood heat residue: Outbuilding woodstoves and shop heaters send creosote-laden smoke back through return ducts. It coats the inside of supply trunks, and that sticky film traps lint and pollen until airflow drops noticeably.
- Crushed flex from remodels: In Lakewood and Cherry Chase, the relentless gut-renovation cycle means a kitchen soffit comes down and some 1962 flex run is found flattened behind it. The leaks start immediately, and the blower motor short-cycles.
- Degraded duct board at the plenum: Original duct board connections at the supply plenum have been baking in attic heat for decades. They delaminate, pull loose, and dump attic air directly into the conditioned space.
Pricing for Air Duct Repair in Sunnyvale, TX
A straightforward Ductwork Repair job in Sunnyvale, like re-taping a section of trunk or reconnecting a single flex run, typically runs $250 to $600. Full Air Duct Replacement of one leg in a ranch attic runs $700 to $1,500. Whole-system replacement in these older homes usually lands between $3,000 and $6,000, depending on how much of the system is accessible and how much demolition the homeowner has already done.

FAQs About Air Duct Repair in Sunnyvale
Every 2 to 3 years is realistic for a Sunnyvale ranch home on the east side, especially if you’re near unpaved roads or open land. The dust load builds faster than you’d think when attic ductwork has 60-year-old seals. If you run a woodstove in an outbuilding, schedule Dryer Vent Cleaning in Sunnyvale and check the return ducts annually. Call (980) 447-2498 and we’ll take a look before recommending a schedule.
It depends on what’s actually wrong. A torn or disconnected joint can usually be repaired with new connectors and sealing. A flex run that’s been crushed flat or has tears along its length in multiple spots is a replacement job. We’ll show you what we’re seeing before we do anything, and you’ll get a written price for the repair or the replacement. Call (980) 447-2498 to schedule an assessment.
Yes, and honest local contractors will tell you the same thing. Once demo starts, 60 years of settled dust gets redistributed directly into the duct system. The soffit comes down, the drywall dust goes airborne, and the return ducts pull it in. We clean the system after rough demo and before finish work, so the new paint and floors don’t get a layer of 1962 attic dust on them. Call (980) 447-2498 to get on the schedule during your remodel.
NADCA is the National Air Duct Cleaners Association, and their standards mean the job includes source removal: agitating debris off the duct walls and extracting it under negative pressure with HEPA filtration, not just vacuuming the registers. On a rural Sunnyvale property where unpaved-road dust and wood heat residue are the main contaminants, NADCA-compliant work is the difference between cleaning the ducts and just moving the dust around. Every job we do follows that standard.
A MERV 8 to MERV 11 filter is the right range for most Sunnyvale ranch homes. Anything higher restricts airflow in older systems that were never designed for high-efficiency filtration, and that restriction causes the same short-cycling and pressure problems as a crushed flex run. If you’ve had ductwork repaired or replaced, MERV 11 is a good ceiling unless you have specific respiratory needs. Call (980) 447-2498 and ask Marcus or the tech about your specific setup.
