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.

Why Linden Air Duct Cleaning Is Nassau Bay’s Preferred Air Duct Repair Company
We know Nassau Bay’s housing stock better than most. The city was built almost entirely in the 1960s for NASA and Johnson Space Center families, which means the homes here share the same construction era, the same original duct materials, and now, the same failure points. When we pull up to a ranch on San Sebastian Lane or a split-level off Point Lookout Drive, we already know what we’re likely to find: fiberglass liner that’s delaminating, supply boots with disconnected collars, and early flex duct that’s been crushed for decades.
Marcus Veale leads our team with a simple standard: the tech’s name and photo arrives before the visit, and a photo ID badge is shown at the door, every time. That’s the Threshold Standard, and it matters in Nassau Bay, where homeowners are rightfully selective about who enters their homes. Our background-checked, identity-verified technicians arrive in clean, marked uniforms. We put the repair price in writing before work starts, and we back every job with a written guarantee. If a covered repair fails, we return at no charge.
We also coordinate scheduling through our Dallas-Fort Worth office, with crews serving Nassau Bay locally. A live person answers the phone 24/7 at (980) 447-2498. No voicemail loops, no callback queues.
Ductwork Installation in Nassau Bay
Ductwork Installation in Nassau Bay means replacing failing sections of existing duct runs rather than patching them indefinitely. For homes in the 77058 ZIP code and surrounding Nassau Bay neighborhoods, this typically involves swapping out original 1960s metal trunk sections with delaminated liner, or replacing early flex duct that has collapsed internally and can’t be resealed. In Nassau Bay, a full ductwork replacement for a typical 1,800 to 2,400 square foot ranch runs between $3,200 and $6,800 depending on access, run length, and how many supplies and returns are involved. Partial installations, like replacing one main trunk line, usually fall between $1,200 and $2,800.
Full System Replacement
When more than about 40 percent of the duct system shows liner failure, crushed runs, or corroded joints, patchwork repair stops making sense. A full replacement gives you new sealed ductwork sized correctly for today’s higher-efficiency AC systems, which matters in Nassau Bay’s saturated air because tighter sealing means less Clear Lake humidity entering the system.
We walk the attic or crawlspace, show you photos of what we found, and give one flat price per system before any material is ordered. No per-vent pricing. No surprises at the end.
Partial Runs and Trunk Lines
Sometimes only one trunk line or a few supply runs have failed, while the rest of the system is sound. We’ll replace just those sections, seal the connections with mastic, and verify static pressure at the air handler before we leave. This is common in Nassau Bay split-levels where the lower-floor supply trunks draw in crawlspace air every time the blower runs.
HVAC Duct Installation in Nassau Bay
HVAC Duct Installation in Nassau Bay covers the connection between the air handler, the supply plenum, and the duct runs that carry conditioned air through the house. In older Nassau Bay homes, this connection point is where we consistently find degraded return duct connections pulling attic and crawlspace air, along with the near-coastal humidity that comes with it, directly into the system. Installing new sealed connections here often costs between $450 and $1,400 for a typical single-system home, though the price depends on access and how much of the plenum needs rebuilding.
Supply and Return Plenums
The plenum is the transition box where air leaves the AC unit and enters the ductwork. On 1960s Nassau Bay ranches, original plenums are frequently sheet metal with failing tape seals that have been leaking for decades. We rebuild these with sealed sheet metal or fiberboard and mastic-seal every seam, because a plenum leak wastes conditioned air into the attic and pulls humid coastal air back through the returns.
Air Handler Connections
If the connection between the air handler and the return duct is loose, the system draws attic air every cycle. That attic air in Nassau Bay carries near-saturated humidity, which condenses inside the duct and feeds the mold growth we so often find downstream. A properly installed, sealed return connection stops that path at the source, and it’s one of the most cost-effective repairs we do on Air Duct Repair calls.
Trusted Brands We Service in Nassau Bay
We service and pair duct systems with air-quality and dryer vent cleaning equipment from Nikro, Honeywell, and Aprilaire. For Nassau Bay homeowners, that matters because we keep stock on hand for the materials these older systems need, including replacement duct liner for the 1960s fiberglass-lined metal trunks we see on nearly every job here. If you have an older Aprilaire media cabinet or a Honeywell bypass humidifier tied into the ductwork, we can service it as part of your repair visit, something few generalist HVAC shops in Clear Lake bother with. We carry professional-grade inspection cameras and sealant materials sized for original equipment, so there’s no second trip while parts ship from a distributor.
Common Air Duct Repair Problems We See in Nassau Bay Homes
- Delaminated fiberglass duct liner. The original liner inside 1960s metal trunks breaks down and sheds gray fiber into the airstream every time the blower runs. We see this on the majority of repair calls in Nassau Bay, and many local contractors keep replacement liner stock on the truck as a standard item because it’s that common here.
- Corroded and disconnected joints behind supply boots. Clear Lake’s humidity creeps into any gap. We routinely find supply boots that have pulled away from the duct, letting saturated air into the system and conditioned air out into the wall cavity.
- Crushed or kinked early flex duct. The first-generation flex runs installed in the 1960s and 70s collapse internally over time. A camera inspection shows the restriction clearly, even when the outside of the duct looks fine from the attic.
- Degraded return connections at the air handler. Loose or torn return duct connections pull attic and crawlspace air directly into your system. In Nassau Bay, that air is wet, and it condenses inside the ducts, feeding chronic mold colonization that a simple cleaning won’t stop.
Pricing for Air Duct Repair in Nassau Bay, TX
Targeted air duct repair in Nassau Bay typically runs $350 to $900 for jobs like resealing a disconnected supply boot, patching a crushed flex run, or replacing a short section of failed liner. Replacing an entire trunk line runs $1,200 to $2,800. Full ductwork replacement for a typical 1960s ranch falls between $3,200 and $6,800. What moves the price is access, how many runs are affected, and whether the liner failure has spread into multiple trunks. We give one flat price per system in writing before work begins, and every repair includes our written 365-Day Done Right Promise with a free second visit if the repair doesn’t hold.

FAQs About Air Duct Repair in Nassau Bay
Because nearly every home in Nassau Bay was built in the 1960s for NASA and JSC families, and the original duct materials are now failing at the same time. Cleaning removes debris, but it can’t fix a duct liner that’s delaminating, a boot that’s disconnected from the trunk, or a return that’s pulling humid attic air into the system. We show you camera footage of what’s actually wrong before recommending repair, so you’re not paying for a cleaning that won’t solve the problem. Call (980) 447-2498 and we’ll walk you through what we see.
Clear Lake and the tidal inlets around Nassau Bay keep the air nearly saturated year-round, and that moisture enters your ducts through any gap, crack, or disconnected joint. Inside the dark, cool ductwork, that moisture condenses and feeds mold growth behind the supply boots and inside the liner. Sealing the ducts is the real fix; cleaning alone just buys time. We seal every repair with mastic and verify the connection before we leave.
We start with a camera inspection of the trunk lines, supply runs, and return connections to map every failure point. Then we give you a written price for the whole job before work starts. On a typical 1960s ranch, that means reconnecting separated boots, sealing joints with mastic, replacing failed liner sections, and checking static pressure at the air handler to confirm the system is moving air properly. The visit usually runs 3 to 5 hours, and you get before-and-after photos of your own ducts.
Yes, we do. Because delaminated fiberglass liner is so common in Nassau Bay’s 1960s housing stock, our techs stock replacement liner sections as a standard item when they roll out to this area. That means most liner repairs finish same-day without waiting on a distributor. Marcus Veale’s team keeps the trucks stocked specifically for the failure patterns we see block after block in Nassau Bay.
The clearest signs are gray fiber dust accumulating on supply registers, musty air from the vents, and rooms that never hold temperature no matter how long the AC runs. A camera inspection confirms it, and we always show you the footage before quoting any work. If the liner is intact and the ducts are sealed, a cleaning is likely the right call. If it’s delaminating, repair is the only fix that stops the shedding. Call (980) 447-2498 and we’ll help you figure out which situation you’re in.
We pulled a camera through a 1965 ranch off Regatta Drive near the Nassau Bay waterfront and found the original fiberglass duct liner had delaminated in the main trunk, shedding gray fiber into the supply and return ducts with every AC cycle. During source removal we uncovered two crushed flex runs off the plenum and disconnected collars at the supply boots feeding the back bedrooms. We reconnected and sealed the joints, replaced the failed liner section, and the static pressure at the air handler dropped enough that the blower motor stopped short-cycling by the end of the visit. That’s the kind of problem we find in Nassau Bay homes week after week.
If your vents are blowing musty air, your energy bills keep climbing, or certain rooms never reach the temperature on the thermostat, call Linden Air Duct Cleaning at (980) 447-2498. We serve all of Nassau Bay with honest pricing, camera-verified findings, and a written guarantee on every repair.
