Why Hollis Air Duct Cleaning Is Weston’s Preferred Duct Sealing Company

We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Weston is built on showing up when we said we would and leaving the site clean.

Our technicians are background-checked and uniformed – you know who’s walking into your home before they arrive. We use professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial crews use, and we explain what each piece does in plain terms while we work. The Garrison Standard requires arriving inside the quoted window, pricing in writing, completing the job by the book, and leaving the site clean. That standard applies to every Duct Sealing in Weston job we take.

Duct Sealing Services in Weston

Duct Sealing Services in Weston address the leaks, gaps, and separations in your HVAC ductwork that waste cooled air and pull contaminants into your living space. In a typical Weston home with 1990s-era flex duct, we find pinhole leaks near air handlers, disconnected joints in attic runs, and gaps where duct meets register boots – all of which force your AC to run longer and harder in our year-round heat. A full-system seal in Weston generally runs $450 – $1,200, with most single-story homes falling in the $550 – $850 range and larger two-story homes with complex duct runs toward the higher end.

Mastic Seal Application

We apply water-based duct sealing mastic, a thick paste that brushes onto joints and small gaps, then hardens into a permanent, flexible seal. Unlike tape, which dries and peels in South Florida’s attic heat, mastic lasts. We use it on every accessible joint in your system, including the hard-to-reach connections above cathedral ceilings common in Weston’s Mediterranean-style homes.

Aerosol Duct Sealing

For systems with extensive leakage throughout the duct run, we offer aerosol sealing, which pressurizes the ductwork and seals leaks from the inside with a non-toxic polymer. This method reaches gaps that manual sealing cannot, and we verify results with before-and-after pressure tests. It’s particularly effective in Weston’s two-story homes, where duct runs through interior walls are inaccessible by other means.

Duct Insulation in Weston

Duct Insulation in Weston protects your cooled air from the brutal attic temperatures that South Florida summers produce. Uninsulated or poorly insulated ductwork in a Weston attic can lose 20 – 30% of its cooling energy before the air ever reaches your living room, which means your AC runs longer, your bills climb, and the oversized systems common here short-cycle even more. Adding or replacing insulation on accessible duct runs typically costs $600 – $1,800 in Weston, depending on linear footage and whether we’re working with rigid metal or the original flex duct.

Attic Duct Wrapping

We wrap exposed supply ducts with formaldehyde-free fiberglass insulation, secured and sealed at every seam. In Weston’s stucco homes, where attic ventilation is often minimal, this barrier keeps 140-degree attic air from warming your 55-degree supply air before it reaches the register. The result is more even cooling, less strain on your compressor, and lower humidity at the vent.

Condensation Control

South Florida’s humidity means condensation on cold duct surfaces, which leads to mold and water damage. Proper insulation with a vapor barrier prevents this. We frequently find in Weston homes that the builder’s original insulation has compressed or torn, leaving bare duct exposed – especially near the air handler, where vibration wears it away first.

Trusted Brands We Service in Weston

We stock parts and materials from Abatement Technologies, Guardsman, and Rotobrush for fast turnaround on Weston jobs – no waiting on a Miami warehouse to deliver what your system needs. Our Nikro negative-air machines and HEPA filtration equipment are the same units commercial contractors use in hospitals and schools, and we maintain them to manufacturer spec so they perform at rated capacity on every job. For filtration upgrades after sealing, we carry Honeywell and Aprilaire products that integrate with most residential systems. When we seal your ducts, we can also evaluate whether your current filter is adequate for Weston’s pollen load and construction dust, or if an upgrade makes sense.

Common Duct Sealing Problems We See in Weston Homes

• Construction debris in “new” flex duct. In Weston’s 1990s master-planned neighborhoods, the first duct problem is often construction debris – drywall dust, sawdust, and drywall-tape scraps left in the flex runs at handover – so a “new” home can need source-removal cleaning sooner than its owners expect while the original flex duct is still too fragile for aggressive brushing.
• Brittle original flex duct from the 1990s. Weston’s housing stock is predominantly Mediterranean-style single-family homes with stucco exteriors, often featuring original flexible ductwork that becomes fragile after 25+ years. Aggressive agitation tools or high-pressure air can tear it and spread debris instead of removing it; the safe approach is gentle camera-guided source removal.
• Oversized AC systems that short-cycle and leave moisture behind. Weston’s oversized AC systems short-cycle in the humid climate, leaving condensation in the ducts. If sealing is done over damp ductwork without addressing moisture first, mold can return quickly near the air handler.
• Pinhole leaks spreading mold spores throughout the home. Technicians frequently find that builder-grade flex ducts installed in the 1990s have developed pinhole leaks, which can spread mold spores throughout the home. In Weston, duct cleaning often uncovers mold growth near the air handler due to the combination of high humidity and oversized AC systems that short-cycle.
