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 Sunset
Air duct repair in Sunset usually costs between $350 and $900, depending on whether we’re sealing a disconnected run or replacing collapsed sections. Most jobs we handle in this part of Miami-Dade County come down to one thing: aging ducts in punishing attic heat. The good news is we can typically diagnose the problem the same day and put the fix in writing before any work begins. Call (980) 447-2498 and we’ll send a technician who knows exactly what Sunset attics do to ductwork.
We’ve worked the Sunset corridor long enough to know that the register in the ceiling isn’t usually where the problem lives. It’s the attic above it. That’s the first place we look, and it’s why homeowners here call us instead of a generic cleaning outfit that only vacuums what’s visible.
Why Linden Air Duct Cleaning Is Sunset’s Preferred Air Duct Repair Company
We don’t ask Sunset homeowners to take our word on anything. Before any tech steps inside your house, you’ll have their name, photo, and background-check confirmation sent to you. At the door, they’ll show a photo ID badge. That’s the Threshold Standard, and it’s been how we operate since 2004. Opening your door to a stranger is a real decision. We treat it that way.
Our service area covers Sunset from SW 72nd Street down past Kendall Drive and out toward the Turnpike. We answer the phone with a live person around the clock, so when a disconnected duct is blowing mold-spore air into a bedroom, you’re not leaving a voicemail and waiting. Every repair we quote gets a written price before work starts, and every repair is covered by our 365-Day Done Right Promise in writing.
Marcus Veale leads our Air Duct Repair team, and the standard he holds is simple: if the repair doesn’t hold, we come back. Free second visit, no argument.
Ductwork Repair in Sunset
Ductwork repair in Sunset means reconnecting, sealing, or rebuilding the duct runs that fail in attics that regularly hit 130 – 140°F. A typical repair here runs $350 – $650 when we’re dealing with disconnected flex runs at the collars, crushed sections, or failing connections at the plenum. More extensive repairs involving multiple runs and mold-stained ductboard run $650 – $900.
What We’re Actually Fixing
Most repair calls in Sunset start with a homeowner noticing black or gray staining around a ceiling register. They assume the duct needs cleaning. When we pull a camera into the attic, we usually find a flex run that’s sagged off its collar, quietly pulling super-heated attic air into the supply side. That attic air carries mold spores from the Everglades wetlands just west of us. Sealing the connection is the fix.
The Written Price Rule
We write the price before work starts. No per-vent add-ons, no surprise invoice at the end. You’ll see the full cost of the repair, and then you decide. If the repair fails within 365 days, we come back at no charge. That’s not a slogan. It’s on paper.
Duct Replacement in Sunset
Duct replacement in Sunset is what happens when the original fiberglass ductboard or first-generation flex duct has degraded past the point of repair. A partial replacement of failed runs typically runs $500 – $1,200. A full system replacement in a late-1960s through 1990s CBS home can reach $2,500 – $4,500 depending on the home’s footprint and how many runs have failed.
When Repair Isn’t Enough
We don’t sell replacement when a repair will hold. But in Sunset’s housing stock, we see a lot of original fiberglass ductboard from the Nixon and Ford years whose interior liner has turned rough and porous. That surface traps mold spores and biological debris instead of shedding them. If the liner is degraded, sealing connections won’t fix what’s happening inside the duct. It’s replacement territory.
Replacement Done Right the First Time
When we replace ducts in Sunset, we rebuild with sealed, insulated flex and verify negative pressure on both the supply and return sides. We also work with air-quality products from Honeywell and Aprilaire when a system needs filtration upgrades along with new ductwork. The goal is a system that doesn’t just move air. It moves clean air.
Trusted Brands We Service in Sunset
We stock repair parts and replacement materials that match the equipment already installed in Sunset homes. Our technicians work with professional-grade equipment from Nikro and Rotobrush for inspection, cleaning, and sealing. For air-quality components, we install products from Honeywell, Aprilaire, and Abatement Technologies. That means faster turnaround on repairs when you need a specific filter housing, a UV component, or a compatible flex section, because we’re not waiting on a part that has to cross two counties.
Common Air Duct Repair Problems We See in Sunset Homes
- Disconnected flex runs at the attic collars. Sunset attics regularly exceed 130°F in summer. Cheap zip ties and aging tape fail, the flex sags off the collar, and the supply side starts pulling raw attic air. You’ll see the stain at the register long before you feel the leak.
- Crushed or collapsed return ducts. The return path in many 1970s CBS ranches off SW 72nd Street wasn’t built for the high-static blowers installed during later AC replacements. The duct collapses inward, and the system starves for air. Bedrooms get stuffy, and mold colonies thrive in the stagnant airflow.
- Degraded fiberglass ductboard liner. Original ductboard in Sunset homes has spent 40 to 50 years absorbing South Florida humidity. The liner turns rough and porous, then traps Cladosporium and Aspergillus spores blowing in from the Everglades. Cleaning it helps temporarily. Replacing it is the permanent fix.
- Supply leaks at the plenum box. The connection where flex runs meet the main plenum is a common failure point in Sunset attics. When those connections loosen, conditioned air dumps into a 140°F attic instead of your living room, and your electric bill shows it.

FAQs About Air Duct Repair in Sunset
Because Sunset attics hit 130 – 140°F through most of the summer, and that heat causes aging flex duct to sag and pull apart at the connections. The visible problem, mold staining around a register, is usually downstream of a disconnected run in the attic. We start there. Call (980) 447-2498 and we’ll show you the camera footage ourselves.
It depends on the condition of the interior liner. If the ductboard is structurally sound and the liner hasn’t turned rough and porous, we can seal and repair connections. If the liner has degraded from 40-plus years of South Florida humidity, repair becomes a short-term patch and replacement is the honest answer. We’ll show you what we see before we quote anything.
Duct cleaning removes what’s accumulated inside the ducts using negative-pressure extraction, HEPA vacuuming, and agitation tools. Duct repair fixes the physical failures: disconnects, crushed runs, leaking plenums, degraded liners. In Sunset, the two often belong together, because a duct that’s leaking attic air just re-contaminates everything the cleaning just removed.
Yes, when the source is a disconnected or leaking duct run. Sunset sits directly downwind of the Everglades, and the wetlands push high ambient mold-spore loads into residential air intakes year-round. If your attic ducts are pulling raw attic air, sealing and repairing those runs stops the unfiltered pathway that’s feeding spores into your living spaces. If your ducts are intact, the fix is filtration instead.
We use professional-grade equipment from Nikro and Rotobrush for inspection and installation work, and we install air-quality components from Honeywell, Aprilaire, and Abatement Technologies. For duct sealing and rebuilds, we use Guardsman-sealed flex. These are trade-trusted brands chosen because they hold up under South Florida attic conditions.
