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 Duct Sealing Across Orangetree
If you’re paying too much to cool a home that never quite gets comfortable, the problem is likely in your attic. Duct sealing in Orangetree typically runs $450 – $1,200 for a whole-home seal, depending on how many runs have separated from their collars and how much of your flex duct needs re-strapping or replacement. Our crews are out in Orangetree and the surrounding Collier County subdivisions regularly, and we schedule from our Miami office so we can route a truck to your door without the delays that come from dispatching out of Fort Myers or Naples. Call (361) 326-5060 for a free written estimate.
We’ve worked enough homes in Orangetree and Orange Blossom Ranch to know the pattern. Your builder-grade flex duct was installed fast during the 2000s boom, strung through 140°F attics with minimal support, and left to sag, kink, and pull loose at the plenum connections. Nobody cleaned it. Nobody checked it. Now you’re cooling your attic instead of your bedrooms, and your FPL bill shows it.
Why Hollis Air Duct Cleaning Is Orangetree’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing team has handled enough Collier County jobs to recognize an Orangetree attic before we even climb the ladder. The flex duct, the R-6 insulation sweating through the vapor barrier, the air handler mounted on a plywood platform over the hallway – we’ve sealed hundreds of these systems.
Our technicians are background-checked and uniformed, and they work under The Garrison Standard: arrive inside the quoted window, price the job in writing before touching anything, finish by the book, and leave the site clean. That standard matters in Orangetree, where homeowners moved here for predictability and expect the same from their contractors.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no “we’ll call you back Monday.” When you’re staring at a disconnected duct run blowing $400 worth of cooled air into your attic, you want a human who can get a crew routed.
Every duct sealing job we do in Orangetree carries our 365-Day Done Right Promise in writing. If the seal fails, if a collar separates, if you feel a drop in airflow – we come back and make it right at no charge, including a free second visit. That’s not a slogan. It’s printed on your invoice.
Duct Insulation in Orangetree
Duct Insulation in Orangetree is usually the second half of the conversation after we seal the leaks. Your attic flex duct already has some insulation, but after twenty years of 140°F summers, that R-6 or R-8 jacket has compressed, torn at the strapping points, and absorbed enough moisture to lose most of its thermal resistance. We remove the damaged wrap, seal every joint and seam with mastic, then install new insulation rated for Florida attic conditions.
Most Orangetree homes need this most at the plenum connections and where long runs sag against trusses. Those contact points crush the insulation and create cold spots that sweat into the drywall below. You’ll notice it as brown ceiling stains near the master bedroom or over the kitchen, especially in July when humidity pushes 80% and your condensate line is already working overtime.
When Insulation Beats Replacement
Not every deteriorated duct needs tearing out. If the flex liner is intact and the wire helix hasn’t rusted through, we’ll recommend insulating in place. That saves you the cost of full duct replacement, which in Orangetree runs $2,500 – $5,500 for a typical 2,200 square foot home. Our written estimate breaks out both options so you can decide.
Vapor Barrier Integrity
Florida building code requires a sealed vapor barrier on attic duct insulation. Many Orangetree homes were built with tape-sealed barriers that failed within five years. We use proper closure systems and mechanical fasteners that hold up to attic heat cycling, not the foil tape that turns to powder.
HVAC Duct Sealing in Orangetree
HVAC Duct Sealing in Orangetree starts with a pressure test, not a sales pitch. We pressurize your duct system and measure the leakage rate against the conditioned floor area. In Collier County, code allows up to 12% leakage for new construction; we regularly find Orangetree homes running 25 – 40% because the original builders never sealed the boots, plenums, or crossover joints with mastic. That’s conditioned air you’re paying to lose.
Our crews use professional-grade equipment – Nikro negative-air machines to maintain pressure during the seal process, and mastic compounds rated for the temperature swings your attic sees. We don’t use duct tape. Duct tape fails in attics; the adhesive degrades and the backing separates. We use brush-applied mastic that remains flexible and bonded for the life of the system.
The “Fallen Duct” Call
The most common emergency call we get in Orangetree is the bedroom that suddenly won’t cool. We climb into the attic and find a flex run that has pulled completely off the air handler collar or a wye connection, usually because the original strap failed and twenty feet of duct has been hanging by its own weight. We reattach with proper supports, seal with mastic, and add hanger straps every four feet so it doesn’t happen again.
Multi-Handler Homes
Larger Orangetree homes in the Orange Blossom Ranch area often run two air handlers – one for each floor or for a split plan. These systems have more connection points, more potential leak paths, and more complexity in balancing airflow after sealing. We test each zone independently and provide written before-and-after leakage numbers for every handler.
Trusted Brands We Service in Orangetree
We carry equipment and materials from Abatement Technologies, Rotobrush, and Guardsman – the same professional-grade tools commercial crews use in hospitals and schools, not hardware-store patch kits. For Orangetree homeowners, that means we can complete most duct sealing jobs in a single visit without waiting on parts shipments from Tampa or Miami. Our trucks stock mastic in multiple viscosities, insulation jackets in R-6 and R-8, and replacement flex duct in the diameters common to Collier County residential construction. If your system needs a filtration upgrade while we’re sealing, we also source Honeywell and Aprilaire media cabinets that drop into existing return plenums without major modification.
Common Duct Sealing Problems We See in Orangetree Homes
- Disconnected collar joints in 2000s-era flex duct. The original installers in Orangetree’s building boom used minimal mastic and sometimes none at all. After two decades of vibration and thermal expansion, the collars separate. Homeowners notice it first as a hot room and a spike on their FPL bill.
- Sagging runs that have crushed or torn at truss contact points. Long flex duct spans through Orangetree attics were often strapped too far apart. The duct sags, the inner liner kinks and tears, and the insulation compresses to nothing. We re-strap with proper support spacing and replace damaged sections.
- Condensation damage from unsealed vapor barriers. Orangetree’s humidity stays above 70% for months, and any gap in the duct insulation’s outer jacket lets warm attic air contact the cold duct surface. Water forms, soaks the insulation, and breeds mold. We seal the vapor barrier as part of every insulation job.
- Negative pressure pulling attic air into return leaks. When supply ducts leak, the system goes into negative pressure and draws hot, dusty attic air through every gap in the return path. In Orangetree, that attic air carries pollen, fiberglass particles, and mold spores straight into your living space. Sealing the return side is often more important than sealing supplies.

We give you one flat price per system, agreed in writing before we start. No per-vent pricing, no add-ons at the door, no “we found another problem” surprises.
