We’ve worked in Alafaya long enough to know the pattern. Nearly every home here was built from the 1980s through the 2010s as slab-on-grade with flex duct strung through unconditioned attics. That construction style means our Duct Sealing crews spend almost every Alafaya visit in a 130°F attic, not a basement or crawlspace. Roy Castellanos and our team understand how the local heat and humidity attack those flex runs differently than metal ducting would.

Dispatch and scheduling for Alafaya jobs are coordinated from our Miami office, but the crews that arrive at your door live and work in the Orlando metro area. They know the difference between a Waterford Lakes subdivision built in 2005 and a 1992 original off Alafaya Trail. That local knowledge matters when we’re tracing a disconnected boot buried in two decades of blown insulation.

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

Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004, and our reputation in Alafaya is built on showing up inside the quoted window and pricing every job in writing before we touch anything. Homeowners here aren’t looking for the lowest teaser quote; they’re looking for the crew that won’t turn a $400 estimate into a $900 invoice once the van is in the driveway.

Our response time to Alafaya neighborhoods is typically same-week, often within two to three days. We serve communities from the Avalon Park area down through Waterford Lakes and across to the subdivisions near the University of Central Florida. Calls are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No “we’ll call you back Monday.”

Every technician is background-checked and uniformed. You know who’s walking into your home before they arrive. And every duct sealing job carries our 365-Day Done Right Promise in writing: if the seal fails or the problem returns within a year, we come back and make it right at no charge, including a free second visit. That’s The Garrison Standard. It’s not a slogan; it’s the operational code we follow on every Alafaya job.

HVAC Duct Sealing in Alafaya

HVAC Duct Sealing in Alafaya is almost exclusively attic flex-duct work, not the basement metal-duct sealing you’d find in older Northern markets. Our crews seal the joints, collars, and boots that connect your air handler to the supply and return runs that feed each room. The goal is simple: every cubic foot of conditioned air should reach your living space, not leak into a 140°F attic.

Most Alafaya homeowners need HVAC duct sealing when they notice uneven cooling between rooms, a musty smell right after the AC cycles on, or utility bills that spike through July and August. Because your system runs nearly every day of the year here, even a 15% leak rate forces the blower to work harder and longer. Sealing restores the airflow the system was designed to deliver.

A typical whole-home HVAC duct sealing in Alafaya runs $350 – $850. Smaller partial seals or single-run repairs can land in the $180 – $340 range. The final price depends on how many joints and boots need attention, whether we need to remove and replace degraded flex sections, and whether a camera inspection reveals hidden disconnects under the insulation.

Attic Heat Damage to Flex Joints

The original tape or mastic on your duct joints was never meant to survive fifteen years of 120 – 140°F attic cycles. We see this constantly in Alafaya’s 1990s and 2000s builds. The adhesive dries, cracks, and lets go. Our crews strip the old material, reconnect the run, and seal with fresh mastic rated for Florida attic conditions.

Camera Inspection Before Sealing

We run a camera through the system before we quote. In Alafaya’s slab-on-grade homes, disconnected supply boots often hide under blown insulation with no symptoms except a hot bedroom and a faint attic smell. The camera finds what you can’t see from the register. Then we seal what matters.

Duct Repair in Alafaya

Duct Repair in Alafaya usually starts with a homeowner complaint that sounds like a cleaning issue but turns out to be physical damage. Crushed flex runs from a cable installer crawling through the attic. A return collar that has separated completely from the air handler. A supply boot whose connecting duct has pulled loose and is dumping conditioned air into the insulation. These aren’t dirt problems. They’re mechanical failures that sealing alone won’t fix.

We recommend duct repair when a camera inspection shows collapsed, torn, or disconnected sections, or when mold growth has degraded the duct liner beyond what cleaning can restore. In Alafaya’s humidity, that last point matters more than in drier climates. Condensate collects at seams and collars, and once the liner is compromised, replacement is the only lasting fix.

Duct repair in Alafaya typically costs $280 – $620 depending on how many feet of flex need replacement, whether the air handler collar itself is damaged, and how much insulation removal and replacement is required. We price this in writing before we cut anything.

Disconnected Boots and Collars

On a 1996 home off Alafaya Trail, our tech ran a camera inspection and found the return-side flex collar at the air handler had separated, dumping conditioned air straight into the attic and pulling attic dust back through the supply and return ducts. We reconnected and mastic-sealed the collar, then sealed the loose boot at two bedroom registers, and the homeowner’s musty odor complaint stopped within a day.

Crushed or Collapsed Runs

Alafaya’s attic trusses create tight crawl paths, and we’ve found flex runs flattened by years of storage traffic or a single careless service call. A crushed run doesn’t just leak; it chokes airflow to entire zones. We replace the damaged section, support it properly, and seal the new connections.

Trusted Brands We Service in Alafaya

Our Alafaya crews carry professional-grade equipment and materials from Nikro, Honeywell, and Aprilaire. The Nikro negative-air machines we use for pre-sealing cleaning are the same units commercial contractors run on office buildings. For filtration upgrades after sealing, we stock Honeywell and Aprilaire media cabinets and electronic air cleaners. We don’t order parts from a warehouse three states away. Our Orlando-area inventory means most Alafaya jobs are completed in a single visit without waiting on shipping.

Common Duct Sealing Problems We See in Alafaya Homes

• Baked-apart flex joints. Attic heat in Alafaya routinely hits 120 – 140°F, and that thermal cycling dries the original mastic or tape on flex duct joints until it cracks and separates. Sealed runs silently reopen, and your conditioned air leaks into the attic for years before you notice.
• Humidity-driven mold at seams. Central Florida’s year-round humidity keeps condensate on metal collars and inside duct liners. A seal that ignores the moisture source fails again within a season, often with visible mold. We address both.
• Disconnected supply boots hidden in insulation. Because Alafaya homes are slab-on-grade, boots buried in blown insulation go completely unnoticed until a camera inspection. The blower motor pulls hot attic air through every gap, and the homeowner only knows something is wrong because the bedroom never cools.
• Return collar separation at the air handler. The flex-to-metal connection at your air handler carries the highest pressure differential in the system. In Alafaya’s heat, this collar is the first to fail, and when it does, it pulls unfiltered attic air directly into your living space.
