Fast, Reliable Duct Repair & Sealing Across Naples
Duct repair and sealing in Naples typically runs $180-$650 depending on whether you’re patching a single flex duct run or resealing an entire system, and most jobs are completed in one visit. We answer calls live 24 hours a day, and our technicians are usually on-site in Naples within a few hours of your call. If you’re noticing weak airflow, musty odors when the AC kicks on, or rooms that never cool evenly, the problem is often degraded ductwork in your attic - something we see constantly in Naples’s 1980s-2000s-era slab homes where all ducts run through spaces that hit 140-160°F in summer.
We’ve been in this trade since 2012, and Naples presents a specific set of problems you don’t see inland. The combination of extreme attic heat, salt-laden coastal air, and the seasonal vacancy pattern unique to Southwest Florida means duct systems here fail differently than they do almost anywhere else in the country. Our Duct Repair & Sealing team knows what to look for, and we show you before we start with a camera inspection of every accessible duct run.

Why Bellows Air Duct & Vent Co. Is Naples’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in Naples over decades of showing up when we say we will and standing behind the work. Our 90-Day Done Right Promise is non-negotiable: if something isn’t right, we return at no charge with no paperwork required. That promise has been stamped on every job since 2012.
Naples homeowners call us because we don’t bait-and-switch. The price we quote on the phone is the price on the invoice. Before we lift a single tool, we show you camera footage of your ductwork so you can see the problem for yourself. After we’re done, we show you the results. No claims without proof.
Our technicians are background-checked, uniformed, and equipped to handle most repairs in a single visit. Calls are answered by a live person, 24/7 - not a voicemail system, not an app. When you’re dealing with a duct system that’s been sitting in a 150°F attic for years, you want someone who knows what they’re looking at, not someone reading from a script.
We also know the local terrain. From the concrete block subdivisions near Golden Gate to the high-rise condos along Gulf Shore Boulevard, we’ve worked in Naples’s varied housing stock long enough to recognize the failure patterns before we even enter the attic.
Our Duct Repair & Sealing Services in Naples
Duct Sealing
Most Naples homes lose 20-30% of conditioned air through leaks at joints, seams, and connections before it ever reaches the rooms. In our climate, that’s not just wasted money - it’s an open invitation for humid attic air to get pulled into your system. We seal every accessible joint with professional-grade mastic sealant, not tape that will fail in the heat. A typical duct sealing job in Naples runs $350-$650 for a whole-house seal on a standard 2,000-square-foot home. We also offer $50 off any repair over $250.
Flex Duct Repair
Flex duct is the dominant duct type in Naples’s slab-built subdivisions, and it’s where we see the most failures. The insulation wrap degrades after years in 140-160°F attics, the inner liner tears at bends and supports, and the wire helix corrodes in salt air. We replace damaged sections with new insulated flex duct rated for Florida attic conditions, secure it properly to prevent future sagging, and seal all connections. Single-section repairs typically run $180-$340; multiple runs or full replacement can reach $800-$1,400.
Metal Duct Repair
Metal ductwork is more common in the luxury high-rises along Park Shore and Pelican Bay, where shared vertical chases require rigid construction. Salt air accelerates corrosion on galvanized steel, particularly at seams and where condensation collects. We patch small corrosion holes, replace deteriorated sections, and apply protective coatings where appropriate. Metal duct repair in Naples generally ranges $250-$600 depending on access difficulty and extent of damage.
Duct Insulation
Uninsulated or degraded duct insulation in a Naples attic is like trying to cool your house with an ice cube on a sidewalk. We install new foil-faced insulation wrapped to proper R-value for our climate zone, with particular attention to plenums and trunk lines that see the most thermal stress. Duct insulation work runs $400-$900 for most homes, with larger or multi-zone systems higher. Every insulation job includes verification that the vapor barrier is intact - critical in a climate where dew point rarely drops below 65°F.

Trusted Brands We Service in Naples
We stock parts and equipment from Nikro, Honeywell, and Aprilaire - the same brands serious HVAC contractors specify for Florida’s demanding conditions. For that Pelican Bay condo we mentioned, the Aprilaire whole-home dehumidifier we installed was the right tool for a specific Naples problem. We don’t show up hoping we have what you need. Our trucks carry the inventory to complete most repairs without a return trip, because nobody wants to wait through another afternoon of 90-degree humidity while parts get ordered.
Common Duct Repair & Sealing Problems We See in Naples Homes
- Attic heat degradation. Summer attic temperatures of 140-160°F cook the adhesive in flex-duct insulation and dry out mastic seals. Within 10-15 years, most Naples homes have significant air loss at joints that were tight when built.
- Salt-air corrosion on metal ductwork. Coastal condos in 34103 and 34108 see accelerated rust on galvanized steel ducts, especially in shared vertical chases where humidity concentrates and maintenance access is limited.
- The snowbird mold cycle. Homes vacant May through October with thermostats set to 80°F or higher allow condensation on cooler duct surfaces when outdoor humidity pushes above 90%. We regularly find visible mold around supply registers in October - not from broken systems, but from the interaction of vacancy and climate.
- Collapsed or sagging flex duct. Poor original support and decades of heat cycling cause flex duct to sag, kink, or separate from collars. The 34114 and 34116 areas have entire subdivisions built in the 1990s now hitting this failure window simultaneously.

FAQs - Duct Repair & Sealing in Naples
The mold appears because five months of 80°F thermostat settings combined with Gulf Coast humidity above 90% allows condensation on cooler duct surfaces, creating ideal conditions for microbial growth that spreads when full AC operation resumes in October. This pattern - what we call the snowbird mold cycle - is unique to Naples’s seasonal vacancy concentration and doesn’t occur at the same scale in year-round cities like Fort Myers or Sarasota. We recently sealed and insulated flex ducts in a Pelican Bay (34108) condo that had been vacant for six months. The owner returned to find mold blooms around every supply register, despite the AC running. We replaced the degraded flex duct insulation, applied mastic sealant to all joints, and installed a new Aprilaire whole-home dehumidifier to break the moisture cycle. If you’re opening a seasonal home this fall, call (844) 685-6342 for a pre-occupancy duct inspection.
Yes, high-rise condos in 34103 and 34108 have shared vertical duct chases and multi-zone systems that require coordination with building management and often specialized access equipment. Our technicians have worked in these buildings and understand the protocols - we don’t show up unprepared for a 20th-floor mechanical chase. Call (844) 685-6342 and we’ll review your building’s specific requirements when you schedule.
Salt air accelerates corrosion on galvanized steel ducts by 2-3 times compared to inland environments, particularly at seams and low points where condensation collects. We see this most in coastal condos and homes within a mile of the Gulf, where metal ducts can develop pinhole leaks in 10-15 years that would take 14+ years inland. Our repairs include protective coatings where appropriate, and we inspect for early-stage corrosion during every camera evaluation. Call (844) 685-6342 if you smell musty air near coastal-facing rooms.
Not always, but it’s needed far more often here than in cooler climates. Any duct running through a 140-160°F attic without intact insulation is dumping cooled air into a furnace. We evaluate insulation condition during our camera inspection and recommend replacement when the vapor barrier is compromised or R-value has degraded below Florida climate standards. The $400-$900 investment typically pays back in 2-3 summers of reduced AC runtime. We include insulation assessment at no extra charge with every duct repair estimate.
Yes, a properly functioning system set to 80°F or higher during vacancy will still allow mold growth because the duct surfaces remain cool enough for condensation when outdoor humidity exceeds 90%. The AC isn’t broken - it’s simply not running enough to dehumidify. That’s why we recommend dehumidifier integration for seasonal homes, not just duct sealing. If your Naples home sits empty each summer, call (844) 685-6342 before you leave and we’ll design a moisture management strategy specific to your system.
