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.

Call Linden Air Duct Cleaning at (980) 447-2498 for a written, flat price before any work begins.
Why Linden Air Duct Cleaning Is North Miami’s Preferred Air Duct Repair Company
North Miami homeowners call us because we do not treat duct repair as an upsell opportunity. Our Air Duct Repair team has spent years working inside the tight, uninsulated attic cavities that define this city’s housing stock, and we know what those conditions do to flex duct. We’re familiar with the blocks around Arch Creek, the neighborhoods east of NE 2nd Avenue, and the low-rise multifamily buildings west of Biscayne Boulevard. We show up in a clean, marked van, and the technician’s name and photo arrive on your phone before we do.
Marcus Veale, who leads our repair crews, has made one rule for every North Miami job: the price gets put in writing before any work starts, and it does not change. That’s part of the Threshold Standard we’ve operated under since 2004. Every technician is background-checked, identity-verified, and photo-badged at your door. The 365-Day Done Right Promise covers every repair we make in North Miami. If the repair does not hold, we return at no charge. That’s not a promotional line. It’s written on your estimate and on your invoice.
We also answer the phone with a live person, not a recording. At 3 a.m. or 3 p.m., a real human picks up. For homeowners in North Miami who are home alone or have young kids, that’s more than a convenience. It’s the reason they choose us over the coupon mailers.
HVAC Duct Installation in North Miami
HVAC Duct Installation in North Miami usually means one of two things: either new duct runs for a system that was never properly sized, or replacement of original 1950s – 70s flex duct that has failed beyond repair. In North Miami’s CBS homes, the original retrofit often used undersized, poorly routed flex that was never meant to handle a modern central air system. Installing new R-8 insulated duct in those tight attic cavities is different from new-construction work. It requires cutting access where none exists, working around trusses and low-clearance areas, and sealing every connection with mastic, not tape. A full HVAC duct installation in North Miami typically runs $2,800 – $6,500 depending on the number of runs, the length, and access difficulty. Marcus Veale personally reviews the camera inspection before recommending installation over repair.
Retrofit Duct Runs for Older CBS Homes
We size every new run to the air handler’s actual static pressure, not to whatever was there before. In a 1960s concrete-block home, that makes a measurable difference in airflow and amp draw. The blower doesn’t work as hard when the runs are right.
R-8 Insulated Flex in Hot Attic Spaces
North Miami attics reach 130 – 140°F in summer. Uninsulated or under-insulated metal duct sweats constantly in that heat plus 75% relative humidity. We only install R-8 or better insulated ducts here because anything less breeds condensation, then mold.
Air Duct Replacement in North Miami
Air Duct Replacement in North Miami is the honest answer when original flex liner has shed, collapsed, or been pulled apart by years of salty, humid air. We see this constantly on the older blocks east of NE 2nd Avenue and around Arch Creek. Replacement means physically removing the failed duct back to the plenum or air handler, then installing new, properly sealed runs. The cost for a partial replacement in North Miami runs $900 – $2,400 when one or two runs have failed. A full-system replacement runs $2,800 – $6,500. Every replacement job includes a written guarantee and a free second visit if a covered repair fails within 365 days. Before we replace anything, you get a camera inspection. You’ll see the damage with your own eyes, not just take our word for it.
Original Flex Duct Liner Failure
When the inner plastic liner of 1960s flex duct degrades, it sheds fiberglass strands into the airstream. You’ll see them on registers and ceiling vents. No cleaning removes this. The duct has to come out.
Disconnected or Crushed Runs in Tight Attics
We often find runs that separated at the boot or got crushed under storage boxes and insulation batts. Those aren’t a full replacement situation. We reconnect, reinforce, and seal them, then verify airflow at the register before we leave.
Trusted Brands We Service in North Miami
Our North Miami repair trucks carry R-8 flex duct, mastic, boots, and registers compatible with the systems we see most in this area, and we use professional-grade equipment from Rotobrush for inspection and negative-pressure extraction on repair prep. For clients concerned about indoor air quality after a repair, we stock and install products from Aprilaire and Abatement Technologies. Because we keep common parts local to our South Florida operation, most North Miami repairs do not require a second visit to source materials. That’s a function of scheduling discipline, not luck.
Common Air Duct Repair Problems We See in North Miami Homes
- Heat-cooked flex duct liner from 1950s – 70s retrofits. Original flex duct in North Miami’s CBS homes was not built for modern AC run times. The liner breaks down under years of 130 – 140°F attic heat, shedding fiberglass and reducing airflow.
- Disconnected runs hiding in uninsulated attic cavities. The runs were never sized correctly for modern central air, and decades of expansion and contraction separate them at the joints. A disconnected run sends conditioned air into the attic, not your bedroom.
- Crushed branch ducts under storage and insulation. Tight attic spaces invite homeowners to store boxes on top of ducts. We find crushed runs on nearly every older North Miami block. The fix is often simple, but it requires knowing where to look.
- Deteriorated duct tape joints and boot connections. Decades of salty, humid air above 75% relative humidity causes tape to dry, peel, and fail. Every gap pulls exterior air into the system, seeding mold and humidity throughout the supply and return ducts.
Pricing for Air Duct Repair in North Miami, FL
A typical air duct repair in North Miami runs $350 – $1,850. Simple jobs, like resealing separated joints or reconnecting a single collapsed run, land at the lower end. Partial replacement of failed flex duct runs $900 – $2,400. Full HVAC duct installation or complete replacement runs $2,800 – $6,500. The two biggest variables are attic access difficulty and how many runs need work. We do not quote per-vent prices or teaser rates that balloon once our van is in your driveway.

FAQs About Air Duct Repair in North Miami
If fiberglass strands are appearing on your registers, the inner liner of your original flex duct has deteriorated and is shedding into the airstream. That’s a replacement issue, not a repair one, because the duct material itself is breaking down. No amount of sealing or cleaning fixes a liner that’s already coming apart. A camera inspection through the register will confirm the extent of it, and then we replace the failed runs back to the air handler. Call (980) 447-2498 and we’ll get you scheduled. Estimated replacement cost for partial runs in North Miami is $900 – $2,400.
North Miami’s 1950s – 70s CBS homes had central AC retrofitted into attic cavities that were never designed for ductwork. Those attics hit 130 – 140°F in summer, with relative humidity above 75% year-round and salty air from the coast. The combination cooks flex duct liner, separates taped joints, and feeds mold through any micro-tear. Newer suburbs typically have purpose-built duct chases and R-8 insulation from day one. In North Miami, the original material was often R-4 or uninsulated, and it’s been degrading for 50-plus years. That’s the difference.
Every air duct repair in North Miami from Linden Air Duct Cleaning starts with a camera inspection of the affected runs so you can see the damage. The repair itself includes reconnecting separated runs, sealing joints with mastic, replacing failed flex duct where needed, reinforcing crushed branches, and verifying airflow at each register before we leave. You also get the written price before work starts, a written guarantee on every repair, and a free second visit within 365 days if a covered repair does not hold. Nothing is left to trust alone. Call (980) 447-2498 for a free estimate.
Yes, and we do this regularly for landlords and property managers in North Miami’s long-term rental stock. If a single run is crushed or a joint has separated, we repair just that section. We do not push full replacement unless the camera inspection shows the liner has failed or the runs are so degraded that repair would be throwing money away. You’ll get photos and the inspection footage before any decision is made. Written pricing applies to rental work exactly as it does for owner-occupied homes. Call (980) 447-2498 and ask for Marcus Veale.
If you have weak airflow, visible fiberglass strands, rooms that never cool, or unexplained dust on the furniture, that points to a duct repair problem, not a cleaning one. Cleaning removes accumulated debris. It does not fix disconnected runs, crushed ducts, or broken liner. A camera inspection during a service call will tell you exactly which one you’re dealing with. If it’s a cleaning issue, we’ll tell you. If it’s a repair, we’ll show you the problem on screen. Call (980) 447-2498 for a free estimate and we’ll schedule the right inspection.
If your North Miami home’s registers are blowing weak or dust-covered air, stop guessing. Call Linden Air Duct Cleaning at (980) 447-2498. You’ll get a real person on the phone, a flat written price before any work begins, and a technician whose name and photo arrive before we do. Marcus Veale and our repair crews know North Miami’s older homes because we’ve worked inside them for years. If the repair doesn’t hold, we come back. That’s the 365-Day Done Right Promise, and it’s in writing on every job.
