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 Denton
Air duct repair in Denton typically runs $275 – $690 depending on whether we’re replacing a collapsed flex run in a near-campus duplex or sealing disconnected trunk lines in a 1950s bungalow. Most repairs are completed in a single visit, though we always confirm the exact scope and price with you before any work begins. Our technicians know Denton’s housing stock: the converted rentals on Fry and Hickory, the tract homes down in south Denton, and the older builds circling the Square. Call (980) 447-2498 and we’ll send a background-checked, photo-badged technician to your door.
Why Linden Air Duct Cleaning Is Denton’s Preferred Air Duct Repair Company
Denton homeowners don’t have time for a technician who has to learn the city block by block. We’ve worked the near-campus rental corridor enough to know that a 1940s duplex on Hickory has a different duct failure profile than a 2015 build near Rayzor Ranch. That matters when you’re deciding whether a repair will hold or whether the whole run needs replacing.
Every technician who comes to your door in Denton is background-checked, identity-verified, and arrives in a clean, marked uniform. Before the visit, you get the tech’s name and photo. At the door, they show a photo ID badge. That’s the Threshold Standard, and it’s been how we operate since 2004. No one walks into your home without you knowing exactly who they are.
We also put the price in writing before any work starts. Not a range. Not an estimate we’ll revise upward later. A fixed number for the specific repair your system needs. If a covered repair fails during the 365-Day Done Right Promise period, we come back and fix it at no charge.
Air Duct Replacement in Denton
Air Duct Replacement in Denton is a job we handle most often in the older rental stock near UNT and TWU, where original flex duct has collapsed under years of filter neglect and repeated tenant turnover. The job involves removing the failed section, installing properly supported new duct, sealing every connection, and rebalancing airflow at the air handler. In Denton, full or partial duct replacement typically runs $450 – $1,200 depending on accessibility and the length of the run.
Collapsed Flex Duct Runs
Flex duct has an inner liner that, once torn or compressed, chokes airflow to the far end of the house. We see this constantly in Denton’s converted 1920s – 1960s rentals, where five or six tenant cycles pass without a filter change. The blower motor over-amps, the back bedroom never cools, and replacement is the only fix.
Disconnected Galvanized Trunk Lines
Older craftsman homes around the Denton Square often have original galvanized trunk lines patched with tape decades ago. When those patches fail, conditioned air pours into the attic. We cut out the bad section, transition to new flex or metal, and seal everything with mastic. Same-day repair keeps your AC from working against itself through a North Texas July.
Ductwork Repair in Denton
Ductwork repair in Denton covers the smaller failures that still kill your system’s efficiency: separated joints, torn vapor barriers, improperly supported runs sagging against attic joists, and return-air leaks pulling 140-degree attic air into the system. Typical ductwork repair in Denton runs $275 – $575, though repairs requiring multiple access points or extensive sealing push higher.
Sealing and Re-Supporting Existing Duct
Many Denton attics have duct runs that were never properly supported during the original install. A sagging run collects condensation, tears at the joints, and slowly detaches from the boot. We re-support with proper strapping, seal every seam with mastic, and verify the static pressure at the air handler matches spec.
Return Air Leak Repair
A return air leak means your AC is pulling superheated attic air into the system, which drives up runtime and wastes energy every single day. In south Denton tract homes from the 2000s and later, we regularly find return plenums that were never sealed at the drywall transition. Sealing those leaks is one of the highest-ROI repairs a Denton homeowner can make before summer.

Common Air Duct Repair Problems We See in Denton Homes
- Collapsed flex duct in near-campus rentals. The duplexes and converted bungalows along Fry, Hickory, and the avenues just west of UNT sit in a constant tenant turn cycle. We frequently repair the same collapsed flex run on a 12-month rotation because the system never gets cleaned between leases.
- Construction debris in south Denton tract homes. Homes built between 2000 and 2025 in neighborhoods south of Loop 288 often have drywall dust, fiberglass insulation particles, and construction grit sealed inside the ducts from day one. That grit grinds blower motor bearings and coats the evaporator coil.
- Shared dryer vent stacks in apartments and condos. When one tenant’s lint pathway backs up into a neighbor’s unit, the property manager can’t see it from any single apartment. We trace the shared stack, locate the blockage, and repair the damaged section to restore proper airflow and reduce fire risk.
- Patched galvanized trunks leaking into attics. Around the historic Square and the older streets ringing downtown, original metal ductwork has often been patched with tape multiple times over decades. Those patches fail, and conditioned air pours into the attic instead of the living room.
Pricing for Air Duct Repair in Denton, TX
Air duct repair in Denton runs $275 – $575 for sealing, re-supporting, and minor section repairs. Full replacement of a collapsed flex run lands between $450 – $1,200 depending on run length and attic access. The difference in price comes down to two things: how much duct has failed and how hard it is to reach.

FAQs About Air Duct Repair in Denton
Yes. We handle confined attic hatches and tight street parking on Fry, Hickory, and the surrounding blocks regularly. At a duplex on Hickory Street just south of the UNT campus, our tech opened a 1950s unit’s registers and found collapsed flex duct that had been choking the back bedroom for years. The blower motor was over-amping. We ran a camera inspection, cut out the crushed run, replaced it with properly supported duct, rebalanced the supply and return at the air handler, and handed the landlord a before-and-after static pressure reading. She booked the next two units on the block the same week. Call (980) 447-2498 and tell us the address so we can plan for access before we arrive.
Because with roughly 61,000 students at UNT and TWU inside a city of about 140,000, Denton’s near-campus rentals cycle through tenants at a rate that no other comparable DFW city matches. Each turnover brings new occupants, irregular filter changes, and zero duct maintenance. After five or six tenant cycles, the flex duct has collapsed or the return has pulled apart. At that point, cleaning doesn’t help. The duct has to be replaced. We tell landlords exactly what happened and what it costs to fix it permanently.
It very often is. In Denton apartment and condo buildings with shared dryer vent stacks, one tenant’s lint pathway can back up into a neighboring unit’s vent. You’ll notice longer dry times, a burning smell, or the dryer kicking off mid-cycle. That’s a blockage or a separated duct section, and it’s a legitimate fire risk. We trace the stack, locate the failure, and repair the damaged section. If you rent, we’ll work with your property manager to document the finding. Call (980) 447-2498 and we’ll schedule a camera inspection.
Yes, more often than most people expect. Homes built in the 2000s – 2020s wave south of Loop 288 and toward Rayzor Ranch were framed and finished quickly, and construction debris, drywall dust, and fiberglass insulation particles often get sealed inside the duct system before anyone moves in. If the system has never been cleaned, that grit grinds blower motor bearings and coats the coil. We also find return plenums that were never sealed at the drywall transition. Fixing those leaks early is a lot cheaper than replacing a burned-out blower motor two summers later.
Late summer and early fall. Denton sits in the heart of the Ashe juniper pollen belt, and mountain cedar blankets north-central Texas from December through February. That fine particulate works its way into return-air systems. But the bigger factor is AC runtime: from May through September, systems run nearly continuously, and sustained condensation inside flex ductwork creates conditions where mold-related failures surface. If your system has been running hard all summer and rooms aren’t cooling evenly, book the repair before the next tenant cycle or the next pollen bloom makes it worse. Call (980) 447-2498 and we’ll get you on the schedule.
