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 University Park
Air duct repair in University Park usually runs between $350 and $900 when we’re sealing failed junctions, patching crushed flex runs, or replacing short sections of damaged duct. Jobs involving full replacement of rusted galvanized trunks in older custom homes run higher, typically $1,200 to $3,800 depending on footage and access. We’re talking about homes built in the 1930s through 1960s, many of them 3,000 square feet and up, where original metal ductwork has been spliced into flexible runs added during later remodels. Those seams are where things fail. If you’re hearing rattles, feeling weak airflow at distant registers, or seeing dust settle within days of cleaning, call (980) 447-2498. We’ll send a tech who knows University Park’s housing stock because we work in it every week.
Why Linden Air Duct Cleaning Is University Park’s Preferred Air Duct Repair Company
University Park homeowners call us because we’re one of the few companies in the area that talks plainly about what’s actually inside the walls of these older houses. When a 1950s ranch near Lovers Lane has original galvanized plenums tied into flex runs added during a 1990s kitchen expansion, the failure points are predictable. Our techs have seen them enough times to know what they’re looking for before the camera even goes in.
Every technician who arrives at your door in University Park has passed a background check and identity verification under the Threshold Standard. You get the tech’s name and photo before the visit, and they show a photo ID badge at the door. That’s not a nicety. It’s the guarantee that the person standing on your porch is exactly who we said it would be. Marcus Veale, who leads our team, has made that protocol non-negotiable since day one.
We also put the price in writing before any work begins. Not a range. Not a guess. A number you approve. And every Air Duct Repair job we complete in University Park carries a written 365-Day Done Right Promise. If the repair fails within that window, we come back at no charge. That’s the kind of accountability these older systems deserve.
HVAC Duct Installation in University Park
HVAC Duct Installation in University Park typically means adding a properly sized run to a home where a previous remodel cut corners, or where a room addition never got sealed ductwork at all. On streets like Lovers Lane, and in the blocks surrounding SMU, we routinely open up ceilings and find flexible duct that was never connected to the plenum correctly, or metal runs that were abandoned in place when a wing was added. Installation means running new, properly sealed duct from the existing plenum to the new registers, sizing it to the room’s actual air volume requirements, and sealing every joint with fresh mastic. For University Park homes, that usually falls between $900 and $2,600 depending on run length, accessibility through attics and crawl spaces, and whether we need to cut new register openings in finished ceilings or walls.
Replacing Abandoned or Undersized Runs
Some University Park additions were served by duct runs that were too small from day one. That’s especially common in second-story additions above original 1950s first floors. We remove the old run and install correctly sized flex or rigid duct, then balance the system so the far rooms stop starving for air.
New Duct for Renovated Spaces
If you’ve turned what was a 1960s utility room into a full kitchen or a primary suite, the old 6-inch run won’t carry the load. We design and install new supply and return lines that match the room’s real heating and cooling demand, not what the original builder guessed decades ago.
Air Duct Replacement in University Park
Air Duct Replacement in University Park is the right call when the original sheet-metal trunk is rusted through, when crushed flex runs can’t be pulled back into shape, or when failed generational seams have gotten so bad that patching would cost more than replacing the affected section. Homes built between the 1920s and 1960s often have galvanized metal ducts that have been in service for 60, 70, even 90 years. Some are still sound. Others are paper-thin at the seams and leaking air into the attic. Replacement in University Park generally runs $1,200 to $3,800, with the biggest variables being the total linear footage, whether we’re working in a tight attic or open basement, and how much of the old material requires careful demolition around wiring and plumbing.
Partial Replacement of Failed Sections
You rarely need to replace everything. We identify the damaged section with a camera inspection, cut it out, and tie in new material with mastic and mesh at every joint. This is the surgical approach that makes sense in a 4,000 square foot home where most of the original metal is still doing its job.
Full Trunk Line Replacement
When the main supply trunk is rusted, separated, or collapsed in more than a couple of spots, piecemeal repairs become false economy. We quote the full replacement honestly, showing you exactly what’s coming out, what’s going in, and what it costs before we touch a single tool.
Trusted Brands We Service in University Park
We service and install equipment from Rotobrush and Nikro for professional-grade duct and ventilation work, and we’re experienced with air-quality products from Honeywell and Aprilaire when the job calls for filtration upgrades. Because we service University Park regularly, our techs carry common fittings, mastic canisters, and flex duct sizes for the older systems we see on these streets, which often keeps a repair to a single visit rather than a parts run back to the warehouse. If your system includes specialty filtration components from Abatement Technologies, our team can evaluate whether they’re still performing or need servicing during the repair.
Common Air Duct Repair Problems We See in University Park Homes
- Dried and cracked mastic at generational seams. A 1950s galvanized plenum spliced to a 1980s or 1990s flex run, often during a kitchen or addition remodel on streets like Lovers Lane. The mastic dries out, separates, and the open seam pulls attic air, and whatever else is up there, into the house.
- Fiberglass insulation in the supply airstream. Failed junctions under negative pressure don’t just leak air. They actively pull loose fiberglass fibers from attic cavities across the coil and into living spaces. This one is common enough in University Park that we look for it on every camera inspection, because you won’t see it until someone looks.
- Decades of debris packed at every seam. Original sheet-metal trunk lines in 3,000 to 6,000 square foot homes were never resealed at the joints. Dust, pollen, and construction debris settle at each generational seam, slowly choking airflow to the furthest registers. The system runs harder, longer, and the far bedrooms stay warm in August.
- Crushed or disconnected flex runs hidden by heavy pollen loading. The mature live oaks and elms that line University Park streets, particularly around SMU and Lovers Lane, dump extraordinary pollen volumes into HVAC systems during the February through May allergy window. That organic debris masks crushed or disconnected flexible runs that only a camera inspection reveals.
Pricing for Air Duct Repair in University Park, TX
Most targeted repairs in University Park, for example sealing two or three failed junctions and replacing a short crushed section of flex, land between $350 and $900. Partial replacement of a failing plenum-to-flex splice with new fittings and mastic runs $500 to $1,400 depending on access. Full replacement of rusted original trunk lines in older custom homes runs $1,200 to $3,800. The highest costs come from working in very tight attics under low-pitch roofs on 1930s homes, and from careful demolition around original framing. Every job gets a written price before we start, and every repair carries our written guarantee with a free second visit if it fails within 365 days. Call (980) 447-2498 and we’ll give you a number, not a guess.

FAQs About Air Duct Repair in University Park
Yes, and in fact that’s the most common repair we do in University Park. We camera the junction, remove any debris and fiberglass that’s been pulled into the airstream, then reseal the splice with fresh mastic and fiberglass mesh. If the metal on either side is still sound, there’s no reason to replace the entire run. Most of these repairs cost between $500 and $900 per junction. Call (980) 447-2498 and we’ll confirm what you’re dealing with before quoting anything.
The mature live oak and elm canopy in those neighborhoods produces pollen and organic debris loads during the February to May allergy window that newer, more open suburbs simply don’t experience. That material collects at the generational seams in older ductwork, and because systems run nearly continuously from May through October, it packs in faster. Homes near SMU get an extra dose from street trees and the dense older landscaping that defines the blocks around the campus.
A camera inspection shows it immediately. Crushed flex looks like a kinked hose, and a disconnected run shows an open end that should be attached to a boot or plenum. We don’t guess. We run the camera before recommending repair, and we’ll show you the footage so you can see exactly what’s wrong.
Yes. When a return-side or supply-side seam opens under negative pressure, the system pulls air from the attic cavity, and if loose fiberglass insulation is present, fibers enter the airstream. We’ve seen coils coated in it on furnaces in 1930s homes near SMU. That’s a real indoor air quality problem, and it’s why we treat these jobs as more than a simple patch: source removal, then sealing.
We follow NADCA guidelines for duct cleaning, assessment, and repair, and our techs work with Rotobrush and Nikro equipment. We also service and assess air-quality components from Honeywell, Aprilaire, and Abatement Technologies.
