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 Leon Valley
Air duct repair in Leon Valley typically runs $275 – $650 for a single failing run, and $900 – $2,400 when multiple sections of original duct board need replacement. Most repair jobs here trace back to one thing: homes built between the 1950s and 1980s that still carry their first-generation duct systems. If your registers are blowing weak, your attic smells musty when the air kicks on, or you are seeing dust settle back on furniture within days of cleaning, there is a real chance the ducts themselves are the problem. Call (980) 447-2498 and we will send a verified technician to camera-inspect your system and give you a written price before any work starts.
Why Linden Air Duct Cleaning Is Leon Valley’s Preferred Air Duct Repair Company
We work Leon Valley’s postwar streets every week, and we know what hides in these attics. This is not the kind of repair you want handed to someone who has never dealt with 1960s fiberglass duct board delaminating under 140°F attic heat. Our Air Duct Repair team has spent years learning how these specific homes fail, and we bring that experience to every camera inspection.
Every technician who arrives at your door in Leon Valley has been background-checked and identity-verified under the Threshold Standard. Before the visit, you get the tech’s name and photo. At the door, they show a photo ID badge. You know exactly who is walking into your home before they step inside.
Marcus Veale, who leads our team, insists on one standing rule that our Leon Valley customers notice fast: the price goes in writing before the work begins. Not an estimate that becomes a bigger invoice. Not a teaser number. The actual price, on paper, agreed to before we touch a single vent.
HVAC Duct Installation in Leon Valley
HVAC Duct Installation in Leon Valley usually means one of two things: replacing a section of original duct board that has failed beyond repair, or running new flex duct to a room that has been added or converted. With most of this city’s housing stock dating from the 1950s through 1980s, we rarely install into a blank attic. We are almost always adapting to what is already up there.
A straightforward single-room install in Leon Valley, with new flex duct, grille, and sealed connections, typically runs $350 – $700. A full attic re-duct for a 1,600-square-foot ranch home generally lands between $2,800 and $4,800, depending on access and how much old material needs hauling out.
When Original Duct Board Has Failed
There comes a point where the foil facing on old fiberglass duct board has separated to the extent that patching it is a waste of your money. We will tell you when that point is. If the liner has collapsed into the air stream, rebuilding that section with fresh duct board and properly sealed joints is the only repair that holds.
Adding a Return or Rebalancing a Room
Leon Valley ranch homes often have one central return for the whole house, which means the back bedrooms never pull enough air. Installing a dedicated return run restores airflow and keeps those rooms from feeling stale through the long cooling season.
Air Duct Replacement in Leon Valley
Air Duct Replacement in Leon Valley is a bigger job than patching and should not be done unless the existing system has truly reached the end of its life. But in this city, plenty of systems have. When we camera-inspect a duct and the liner is peeling away like old wallpaper, replacement is the honest call.
We price replacement by the run, not by the vent. A single supply or return run, fully replaced and sealed, costs between $275 and $650 in Leon Valley depending on length and attic access. Replacing all accessible supply and return runs in a typical 1,400 – 1,800-square-foot home here runs $2,200 – $4,200, including removal of old material and re-insulating where needed.
What Replacement Actually Involves
We set the system under negative pressure with HEPA filtration while we work, so demolition debris and decades of accumulated dust do not blow through the house. Old duct board and collapsed flex come out through the attic access, not through your living room. New runs go in with sealed, mastic-and-taped connections.
When Replacement Is the Cheaper Long-Term Option
We have looked at Leon Valley homes where the same run has been patched three times. Each patch costs money and the run still leaks. If a duct is failing in multiple places, replacement costs less over five years than repeated patching, and it actually solves the problem.
Trusted Brands We Service in Leon Valley
We run Rotobrush and Nikro equipment, and we build with materials and components from Aprilaire and Abatement Technologies where they fit the job. For Leon Valley’s older systems, we keep common duct board sizes, flex duct, and sealing materials in stock locally, which means we do not have to put a repair on hold waiting on a parts delivery from across the state. If your system needs a specific component, we will tell you what it is, why it is needed, and what it costs before we order it.
Common Air Duct Repair Problems We See in Leon Valley Homes
- Original duct board foil separation. Homes off Evers Road, Bandera Road, and Huebner Road from the 1950s – 1970s often have duct board whose foil facing has peeled back and fallen into the air stream. The “dust” coming out of the registers is sometimes pieces of the duct itself.
- Crushed or disconnected flex ducts. Decades of 140°F summer attic heat degrades the plastic liner in flex duct until it cracks or pulls loose from its collar. Conditioned air dumps into the attic, and the rooms never feel comfortable no matter how low you set the thermostat.
- Ashe juniper pollen saturation. Leon Valley sits right in the path of the December – February cedar fever surge blowing in from the Hill Country. Ducts that are already compromised recirculate that fine allergen load through the house instead of moving it out.
- Return air starvation in single-return ranch layouts. A single central return cannot pull air from closed-off back bedrooms, which hurts both comfort and system efficiency. Many Leon Valley homes we repair were designed this way and never updated.

FAQs About Air Duct Repair in Leon Valley
Because so many homes here still run original fiberglass duct board from the 1950s – 1980s. Once the foil facing separates and the liner starts breaking down, no amount of cleaning restores structural integrity. We camera-inspect first, show you the footage, and only recommend replacement when patching would fail within a year or two. Call (980) 447-2498 to schedule an inspection.
Rooms served by a crushed or disconnected duct get noticeably less airflow than the rest of the house, often while the utility bill stays high. Dust buildup alone does not cause one room to feel stagnant. If you hold a tissue near a register and it barely moves while other rooms blow strong, that is a duct problem. We confirm with a camera inspection and show you exactly what we found before quoting a repair.
Leon Valley sits on San Antonio’s northwest fringe, and from December through February the Ashe juniper pollen load from the Hill Country is heavier here than in cities further east. That fine pollen packs into return ducts and the evaporator coil. If a duct is torn or a run is disconnected, the system pulls pollen-laden attic air straight into the house and recirculates it. A compromised duct during cedar fever season is actively making indoor air worse. Call (980) 447-2498 and we will help you figure out what is going on.
Yes. When we pull out failing duct board from a 1960s attic, we are releasing decades of dust, pollen, and liner debris. Running the system under negative pressure with HEPA filtration while we work keeps that material from blowing through your living room and settling into furniture, curtains, and carpet. It is standard practice on every repair we do in Leon Valley, not an add-on.
Summer attic temperatures here routinely exceed 140°F. That heat is what kills flex duct liners and accelerates foil delamination on duct board. It also means sealant and tape choices matter: we use mastic and foil tape rated for high-heat attic conditions, not the cheap plastic-backed tape that dries out and falls off in a season. If a previous repair on your system is peeling away, heat degradation is often the cause.
