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 Kendall
Air duct repair in Kendall usually means finding and fixing the spots where your AC system is leaking conditioned air, pulling in attic dust, or pumping musty odors through the house. Most of the homes we see in Kendall were built between 1975 and 1995, which means their original flex duct has been baking in 130-degree attics for three to five decades. When that ductwork fails, you feel it as hot spots, higher electric bills, and that faint smell of attic or mildew in the AC stream. If your ducts are showing their age, call us at (980) 447-2498 and we’ll send a background-checked, photo-badged technician to diagnose the problem before anything gets torn apart.
Why Linden Air Duct Cleaning Is Kendall’s Preferred Air Duct Repair Company
We’ve been servicing Kendall homes long enough to know the neighborhoods by name: Kendale Lakes, Kendall Lakes, West Kendall, Country Walk, The Crossings. That matters because Kendall is not one kind of housing stock. The tract homes built in the late 1970s along Kendall Drive have different duct failure patterns than the 1990s subdivisions west of the Turnpike. When a technician pulls up to your block, they should already know what they’re likely to find in your attic. Our team does.
Every technician we send into a Kendall home has been background-checked and identity-verified under the Threshold Standard. You get the tech’s name and photo before the visit. At your door, they show a photo ID badge. We answer our phones with a live person around the clock, so if you call (980) 447-2498 at 6:30 a.m. because your AC came on and the house smells like swamp, you’ll talk to a real human who can make the call on whether we need to come out same day or whether it can wait.
Kendall homeowners also tell us they’re tired of duct companies that quote small and invoice big. So every repair job we do here gets a written price before any work starts. That’s not a promotion. It’s how we’ve operated since 2004 as part of the Threshold Group family, and it’s the only way we’ll do business.
Ductwork Installation in Kendall
Ductwork installation in Kendall becomes necessary when the existing flex duct is beyond repair: collapsed inner liners, disintegrated insulation, separated joints, or contamination that can’t be removed without destroying the duct itself. This is a different job from repair. Installation means we remove the old runs and hang new ones, sized properly for your system and sealed correctly at every connection.
What does that cost in Kendall? A full duct replacement in a typical 1,800 to 2,400 square foot CBS home runs roughly $3,200 to $6,800 depending on the number of runs, accessibility of the attic, and whether the plenum boxes need to be rebuilt. Partial replacement of one or two failed runs typically lands between $650 and $1,400 per run. We put that price in writing before any material gets ordered.
Sizing and Sealing
A duct system that isn’t sized correctly for the AC unit will pull against itself, and in Kendall that means humid attic air gets drawn through any gap in a return duct. We measure airflow and static pressure before recommending a replacement, then seal every joint with mastic, not duct tape. Tape dries out in a South Florida attic within a couple of years. Mastic is permanent.
Attic Access and Removal
Most Kendall attics are tight, low-clearance spaces with trusses every 24 inches. Removing old duct and running new flex requires cutting out the old hangers, pulling the runs without tearing them open and spreading contamination through the attic, then re-hanging new duct with proper slope and support. It’s slow, dirty work. We cover it honestly, and we are careful about not letting the attic insulation get disturbed and blown into your living space.
HVAC Duct Installation in Kendall
HVAC duct installation in Kendall refers to the complete replacement or new installation of the duct network connected to your air handler and condenser, not just a patch job on one failing section. This is the job you’d schedule when a whole-house system of ducts has reached the end of its service life, or when a new AC system is being installed and the contractor discovers the existing ductwork is shot.
In Kendall, a full HVAC duct installation for a standard single-family home costs between $4,000 and $7,500. That includes the supply and return plenums, all branch runs, insulation wrap where needed, sealing, and a balance test at the registers. Homes with multiple zones or two systems will run higher. You’ll get a written price before we touch anything.
Replacing Original 1970s and 1980s Flex Duct
We replace a lot of original ductwork in Kendale Lakes and Kendall Lakes where the basic R-4.2 or R-6 flex from the original build has simply given out. The outer vapor barrier cracks, the inner liner collapses, and the fiberglass batting inside has absorbed decades of moisture. When we pull that out, we bag it in sections and carry it out through the attic access, not through the living room.
New Plenums and Return Drops
Plenum boxes in Kendall attics are often original sheet metal that’s rusted and leaking. A new duct install without new plenums is a waste of money. We build new plenums to match your air handler’s opening, then attach the flex runs with draw bands and mastic. The return drop gets special attention because that’s where the system pulls attic air in if there’s any leak at all.
Trusted Brands We Service in Kendall
The equipment we run on Kendall jobs comes from brands the trade actually trusts: Rotobrush and Nikro for negative-pressure extraction, HEPA filtration, and source removal. When we install new flex duct, we use materials rated for South Florida’s humidity and heat, and we stock common parts locally so turnaround is fast. For homeowners who want air-quality upgrades after a duct repair or replacement, we work with Honeywell and Aprilaire products for filtration and humidity control, and Abatement Technologies for antimicrobial and IAQ solutions that make sense in a post-flood duct system. You don’t have to buy any of it, but we’ll tell you what’s worth spending on and what isn’t.
Common Air Duct Repair Problems We See in Kendall Homes
- Collapsed flex duct inner liners. The inner plastic liner of original flex duct degrades after 30 to 50 years in a Kendall attic. When it collapses, airflow drops and rooms start heating unevenly.
- Separated joints at takeoffs and plenums. The draw bands and tape used in the original 1975 – 1995 installs fail over time. In Kendale Lakes, we regularly find return ducts that have pulled completely away from the grille box, so the system is pulling raw attic air.
- Post-flood mold inside duct insulation. Homes west toward the Everglades that took water during Irma or seasonal flooding often have ductwork that looks dry outside but has wet, contaminated fiberglass batting inside. Cleaning it doesn’t fix it. The duct has to come out.
- Pressure imbalance pulling in humid air. When ducts leak on the supply side, the house goes negative. That pulls warm, wet Everglades air through every crack and door jamb, which is why some Kendall homes feel sticky even with the AC running all day.
Pricing for Air Duct Repair in Kendall, FL
Most air duct repair jobs in Kendall fall between $450 and $1,800 depending on what’s actually failing. A simple leak-sealing call on two or three accessible joints might run $450 to $700. Replacing a collapsed section of flex duct typically runs $650 to $1,400 per run. If the plenum needs rebuilding or a return drop is compromised, you’re usually looking at the upper end of that range. Full duct replacement in a Kendall home runs $3,200 to $6,800.
What changes the price: attic accessibility, how many runs are bad, whether the original duct is R-4.2 or R-6, and whether we’re dealing with water damage that requires containment during removal. You’ll get a written price before any work starts. Call (980) 447-2498 for a free estimate, and we’ll inspect the system and give you the exact number.

FAQs About Air Duct Repair in Kendall
If water rose into the duct interior or soaked the fiberglass batting, replacement is the only correct fix. Cleaning surfaces without removing wet insulation leaves mold spores embedded in the duct material. We document what we find with camera inspection and moisture readings, so you’ll know whether your ducts can be safely cleaned or whether replacement is the honest answer.
Kendall homeowners often get duct replacement covered when the damage is tied to a covered water event and the duct system is part of the insured structure. The key is documentation: before-and-after camera footage, moisture readings, and a written report that connects the duct failure to the water intrusion event rather than ordinary wear. We provide that documentation on every post-storm job. Call (980) 447-2498 and we’ll walk you through what your insurer will want to see.
Kendall’s western edge sits directly against the Everglades, so the air moving through your ducts 10 months a year carries higher spore loads than neighborhoods further east. Layer that on homes built from 1975 to 1995 with original fiberglass flex duct now past its service life, and you get more biological contamination in Kendall duct systems than almost anywhere else in Miami-Dade. If you live in Kendale Lakes or any subdivision west of the Turnpike, this is your daily reality.
We run a camera through the full duct system, probe the inner liner for collapse or separation, and take moisture readings inside the duct material itself, not just the air. The report shows exactly which runs need repair, which need replacement, and which are sound. You get photos and numbers you can hand to your insurer. The inspection is part of the estimate; if you’re not sure whether your ducts were affected by Irma or another flooding event, start there.
New flex duct installed with sealed joints and properly sized plenums doesn’t hold moisture the way your original duct did. We also check the condensate drain and coil pan during the install, because a leaking pan dripping onto new duct will re-create the same problem inside a season. In western Kendall where humidity is relentless, we sometimes recommend a Honeywell or Aprilaire whole-house dehumidifier, but we’ll only suggest it if your AC alone isn’t keeping the humidity below 55 percent.
We’ve repaired, replaced, and documented more post-storm duct systems in Kendall than we can count. Here’s one that shows exactly what we mean. In Kendale Lakes, we responded to a homeowner with recurring musty odors and elevated humidity years after a 2017 Irma flood claim. Their original fiberglass flex duct had been through the flood. The contractor who handled the initial remediation repaired the drywall and painted, but never touched the duct interior. Camera inspection showed separated joints and a collapsed inner liner, with visible biological growth on the batting. We performed source removal under negative pressure with HEPA filtration, replaced the compromised runs with new flex duct, and documented the before-and-after condition with photos and moisture readings so the homeowner could submit it to their insurer. That’s what post-storm duct work in Kendall actually looks like.
If your ductwork is showing signs of failure, or if you’re still not sure whether your post-Irma duct system is safe to breathe, call us at (980) 447-2498. We’ll send a Kendall-experienced technician, give you a written price, and stand behind the work with our 365-Day Done Right Promise in writing. If the repair fails within a year, we come back at no charge. That’s the deal, straightforward and backed.
