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.

AfterFast, Reliable Air Duct Repair Across Longwood
Air duct repair in Longwood typically runs $450 – $1,800 depending on the work required, with most single-run repairs well under $900. The big variable is whether we’re sealing a disconnected run or replacing a section of 45-year-old fiberglass duct board. If your system is leaking air, whistling at the registers, or you have rooms that never seem to cool properly, call (980) 447-2498 and we’ll diagnose it properly. We know Longwood’s housing stock well enough to tell you honestly when a repair makes sense and when you’d be throwing good money after bad.
Why Linden Air Duct Cleaning Is Longwood’s Preferred Air Duct Repair Company
We’ve spent a lot of time in Longwood homes, and the pattern is consistent: 1970s and ’80s tract subdivisions with original duct board that’s been baking in Florida heat and Wekiva-basin humidity for four or five decades. That’s not a generic “old ducts” observation. It means our Air Duct Repair technicians know what they’ll find behind the return grille before they even pull the panel. Longwood walls, Longwood insulation, Longwood pollen load. None of it surprises us anymore.
We don’t ask you to take our word for it. The Threshold Standard applies to every visit: background-checked, identity-verified technicians, a name and photo sent to you before we arrive, and a photo ID badge shown at your door. You know exactly who’s walking into your house, which matters whether you’re home alone with a toddler or retired and cautious about who you let in. Marcus Veale, who leads our team, built our protocols around that specific concern.
Our pricing is put in writing before any work begins. Not an estimate range. A written price. And every repair carries the 365-Day Done Right Promise: if the repair fails, we return and make it right at no charge. That’s not a promotion. That’s been our standing commitment since 2004, as part of the Threshold Group family.
Ductwork Repair in Longwood
Ductwork repair in Longwood means finding and fixing the leaks, disconnections, crushed runs, and failed seams that steal airflow from your system and pump conditioned air into your attic. The work typically runs $450 – $900 for a single run, or $800 – $1,800 when multiple sections need sealing and reconnection. Most Longwood jobs land in the $600 – $1,200 range once we’ve done a full inspection.
Sealing and Reconnecting Failed Runs
A run that’s separated at a joint or crushed behind the air handler is the most common repair we do in Longwood. Airflow drops dramatically, the blower motor strains, and rooms on that branch never reach temperature. We reconnect, seal with mastic and UL-listed tape, and verify static pressure before we leave.
Patching Fiberglass Duct Board
Original 1970s – 80s duct board can be patched when the damage is localized. But we’ll be honest: if the board is shedding fibers at multiple seams or showing microbial growth inside, patching is a stopgap. In Longwood’s humidity, that material doesn’t stabilize. It continues degrading. We’ll show you photos so you can see the condition yourself before deciding.
Duct Replacement in Longwood
Duct replacement in Longwood means removing failing fiberglass duct board or collapsed flexible duct and installing new, properly sized, code-compliant ductwork. A partial replacement of one or two runs runs $600 – $1,400. A full system replacement in a typical Longwood single-story home runs $3,500 – $7,000 depending on the home’s layout, the number of runs, and accessibility. We price the entire job before work starts, so there’s no ambiguity.
Replacing Aged Fiberglass Duct Board
When 40 – 50-year-old duct board is shedding fibers, softening at the seams, or showing microbial colonization, replacement is the honest recommendation. New ductwork with proper insulation and sealed joints restores airflow, reduces dust, and cuts the conditions that let mold return. It’s not the cheapest option, but it’s often the only one that actually solves the problem.
Upgrading Crushed Flex Runs
Early-generation flexible duct from the ’80s loses its shape, kinks, and collapses over time. If we find a crushed run during a repair or routine cleaning, replacing it with modern R-8 flex and properly supporting the run restores full airflow. This is one of those repairs that visibly improves comfort in the back bedrooms within a day.
Trusted Brands We Service in Longwood
We run professional-grade equipment from Rotobrush and Nikro, and we stock parts for the most common Longwood system configurations so we’re not waiting on a distributor when your repair is scheduled. When replacement or filtration upgrades are warranted, we work with air-quality products from Aprilaire and Honeywell. That means a repair visit can often include the exact part and upgrade solution in the same trip, installed by a technician who knows how these systems perform in Florida humidity.
Common Air Duct Repair Problems We See in Longwood Homes
- Fiberglass duct board shedding at the seams. Original board in 1970s – 80s tract homes has lived through decades of condensation cycling from Wekiva-basin humidity. The board swells, softens, and sheds fiber into your airstream. Sealing failing seams helps temporarily; replacing the section is often the real fix.
- Crushed or disconnected runs behind the air handler. We find these during routine cleans all the time. The run gets pinched during a previous service, insulation work, or simply from age. Airflow to half the house drops, and your system runs longer trying to compensate.
- Pollen-packed return bypasses in canopy neighborhoods. Sabal Point and similar oak-shaded streets see extreme spring pollen loads. The first-inch return bypass on aging duct board packs solid within one season, starving the system for air and spreading dust through the supply side.
- Condensation and microbial growth in the plenum. Longwood’s ambient humidity near the Wekiva River basin means interior duct surfaces cycle through more condensation than drier Orlando suburbs. Once the interior insulation gets damp and stays damp, mold and dust-mite contamination become a persistent problem, not an occasional one.

FAQs About Air Duct Repair in Longwood
It depends on the condition of the board, not the age alone. If the board is dry, rigid, and only failing at one or two seams, sealing is a legitimate repair that will hold. If the board is soft, shedding fibers at multiple seams, or showing interior microbial growth, replacement is the honest recommendation. We’ll show you photos from inside your ducts so you can see exactly what we’re seeing. Call (980) 447-2498 and we’ll give you a straight answer, not a sales pitch.
Mold appears as dark, sometimes green or black staining that is adhered to or growing across the duct surface, often with a musty odor. Ordinary dust is loose, gray, and brushes away without staining. Longwood’s humidity means we see real mold contamination in aging duct board far more often than in drier neighboring cities. We’ll confirm visually and recommend either cleaning with source removal or replacement depending on the material’s condition. Either way, you’ll see the evidence first.
Sabal Point sits under a dense mature oak canopy right against the Wekiva basin, so the spring oak pollen load is concentrated and persistent. The first-inch filter bypass on your return grille catches everything, and on aging duct board systems that are already restricted, it packs solid within one season. Lake Mary’s newer, more open subdivisions simply don’t produce the same volume. If your return is packing that fast, the fix is usually a deeper cleaning combined with repairing any restrictions in the return duct work.
Weak airflow in one room usually points to a physical restriction in that run: a crushed section, a disconnected joint, or a damper issue. Cleaning won’t fix a crushed duct. We’ll measure static pressure and airflow at the registers to isolate the problem before recommending anything. If it’s a simple disconnect, the repair is straightforward and we’ll quote it before we start. Call (980) 447-2498 to schedule an assessment.
Yes. We work to NADCA standards on every job and use agitation tools under negative pressure with HEPA filtration whenever we’re doing source removal as part of a repair or cleaning. That means the contaminants we dislodge are captured and removed from the home, not redistributed through your living space. It’s the difference between cleaning that moves dust around and cleaning that actually removes it.
