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.
Fast, Reliable Duct Sealing Across Kissimmee
Duct sealing in Kissimmee typically costs $400 – $900 for a whole-home system, and most jobs are completed in a single visit with the price written before we start. We’re the Duct Sealing team at Hollis Air Duct Cleaning, and we’ve been driving to Kissimmee since 2004 from our Orlando dispatch office. Crews know the area: the resort corridors around Walt Disney World, the older ranch neighborhoods near downtown, and the dense villa communities where parking a service van means coordinating with a gatehouse. When you call (361) 326-5060, a live person answers, and we’ll give you a real arrival window, not “sometime between 8 and 5.”
Why Hollis Air Duct Cleaning Is Kissimmee’s Preferred Duct Sealing Company
We’ve built our reputation in Kissimmee on showing up inside the window and pricing in writing. That’s The Garrison Standard, and it applies to every job we run here.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. No random subcontractor, no van with a magnetic sign.
Dispatch is coordinated from our Orlando office, but the crews serving Kissimmee live here or close by. They know that a 4:00 PM call from a property manager in Windsor Hills means a guest checks in at 5:00, and they know which resort communities require vendor registration at the gate.
Every duct sealing job carries our 365-Day Done Right Promise in writing. If the seal fails or the musty smell returns within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround.
Duct Repair in Kissimmee
Duct Repair in Kissimmee means fixing the physical damage that lets conditioned air escape into your attic, crawl space, or wall cavities. In this market, we see two distinct problems: the flexible duct runs in 1990s – 2000s vacation villas that have pulled loose at the collars, and the metal ductwork in 1970s ranch homes near downtown Kissimmee that has rusted through or separated at the seams after decades of humid air cycling. A typical duct repair in Kissimmee runs $250 – $650 depending on accessibility and how many sections need replacement. We use Nikro negative-air machines during repair work to keep dust out of your living space, and we price the job in writing before touching anything.
Disconnected Flex Duct at the Air Handler
This is the failure we find most often in Kissimmee’s resort villas. The flexible duct pulls away from the plenum or a wye connector, dumping cooled air into the attic and sucking hot, humid attic air back into the system. We reattach with mechanical fasteners, then seal with Guardsman mastic and UL 181-rated foil tape. Standard duct tape fails in a Kissimmee attic within a season.
Rusted Metal Duct in Older Homes
The ranch homes near downtown Kissimmee often have original galvanized steel ductwork. After forty-plus years of condensation, the bottom of horizontal runs rusts through. We cut out the damaged section, fabricate a replacement from sheet metal, and seal the joints properly. This is repair, not sealing, but the two jobs often overlap on the same system.
Air Duct Sealing in Kissimmee
Air Duct Sealing in Kissimmee closes the gaps, cracks, and seams that leak air between your ducts and the unconditioned spaces around them. In a typical Kissimmee home, we seal supply and return plenums, wye connections, register boots, and any accessible joints in the duct trunk. For vacation villas in Kissimmee West and Windsor Hills, we also pay special attention to the flexible duct collars at the air handler, because those gaps are where humid attic air enters and feeds mold growth during vacancy periods. A whole-home air duct sealing in Kissimmee generally runs $400 – $900. We use Aprilaire and Honeywell filtration components where the system design allows, and every seal is checked with a smoke pencil or pressure test before we leave.
Mastic Sealing for Humid Climates
We seal with water-based duct mastic, not tape alone. Mastic remains flexible as the duct expands and contracts, and it won’t degrade in the heat and moisture of a Kissimmee attic. For register boots and plenum connections, we reinforce with UL 181-rated foil tape, then brush on a coat of Guardsman mastic over the tape edge. This is the method specified by ACCA for climates like ours.
Pressure Testing After the Seal
After we seal, we run a duct blaster or smoke test to verify the leakage reduction. In Kissimmee’s short-term rental market, this documentation matters: property managers can show owners that the work was done to a measurable standard, not just “sprayed some stuff in the vents.”
Trusted Brands We Service in Kissimmee
We carry professional-grade equipment and stock common sealing and filtration components for Kissimmee customers, which means faster turnaround and no waiting on parts from a warehouse upstate. Our vans are loaded with Nikro negative-air machines for contained repair work, rotary brush systems from Rotobrush for source removal when sealing follows cleaning, and sealing products including Guardsman mastic and UL 181-rated foil tape. For filtration upgrades tied to sealing projects, we install Honeywell and Aprilaire media filters and Abatement Technologies HEPA filtration where the system design supports it. These are the same brands commercial crews use in hospitals and schools, and we explain what each piece does for your specific Kissimmee home before we start.
Common Duct Sealing Problems We See in Kissimmee Homes
- Vacancy mold in resort villas. In Kissimmee’s resort corridor around Windsor Hills and Kissimmee West, hundreds of 1990s – 2000s vacation villas sit vacant between guests with the AC cranked to 78°F. In this humidity, that much idle runtime lets the air handler cycle moist air through flexible duct runs, and visible mold can appear on the evaporator coil and duct interior in as little as a few weeks. Duct sealing here is judged by whether it closes the gaps feeding that mold factory, not by energy savings alone.
- Disconnected flex duct collars left unsealed. Some crews seal only the visible registers while leaving disconnected flex duct collars at the air handler unsealed. In Kissimmee’s year-round AC cycle, humidity keeps entering the supply and return ducts through those gaps, and the mold comes back within a month.
- Standard duct tape in hot attics. We see this shortcut constantly in vacation rentals: a technician used hardware-store duct tape on a joint in the attic. Kissimmee attic temperatures and moisture degrade that adhesive within a season. The tape peels, the gap reopens, and the next guest smells musty air. We use mastic or UL 181-rated foil tape, period.
- Shared dryer vent stacks in condos and apartments. Kissimmee has dense apartment and condo communities where dryer vents share a common stack. Sealing a shared dryer vent without confirming the run is clear first traps lint and creates a fire risk. The EPA links this to the leading cause of home dryer fires. We inspect with a camera before we seal anything in a shared system.
Pricing for Duct Sealing in Kissimmee, FL
Whole-home duct sealing in Kissimmee typically runs $400 – $900. Duct repair, when sections need replacement, generally falls between $250 – $650. What moves the number: how much of the ductwork is accessible (crawl space vs. fully ducted attic), whether we’re sealing after a cleaning that required source removal, and if the home has a zoned system with multiple air handlers. We do not price per vent. We price per system, in writing, before any work starts. That price does not move at the door. Call (361) 326-5060 for a free estimate. We’ll ask about your home’s age, the type of ductwork you have, and whether you’re dealing with a guest complaint or a maintenance schedule, then give you a real range you can plan around.

FAQs About Duct Sealing in Kissimmee
In a Kissimmee vacation rental, duct sealing determines whether your property passes the management inspection between guest turnovers. The short-term rental boom here means between-guest cleanliness is a brand promise, and duct odors can trigger bad reviews that cost bookings. No other Florida city has this density of professionally managed short-term rentals demanding documented, guest-ready duct sealing. Call (361) 326-5060 if you’re a property manager who needs inspection documentation.
Yes, but we camera-inspect the shared stack first to confirm it’s clear of lint buildup. Sealing a blocked shared vent creates a fire hazard. We document the inspection with photos for your HOA or property manager. Call (361) 326-5060 to schedule a shared-system inspection.
We coordinate with your gatehouse or property manager before arrival. Our vans carry the full equipment roster, so we don’t need a second trip for parts. For communities with vendor registration requirements, we submit documentation in advance. We’ve run enough jobs in Kissimmee West and Windsor Hills to know the drill. Call (361) 326-5060 and we’ll confirm access protocol when we book.
Air duct sealing closes gaps and seams in intact ductwork. Duct repair replaces or rebuilds sections that are physically damaged. On a 1970s ranch near downtown Kissimmee, we often find both: rusted-through metal that needs cutting out and replacing, plus dozens of loose seams that need mastic sealing. We scope the work with a camera inspection and price each component separately in writing. Call (361) 326-5060 for a camera inspection.
Sealing often fixes the musty smell if the odor is coming from humid attic air entering through duct gaps. We were called to a Windsor Hills townhome after a property manager flagged a musty smell in the primary suite between guest turnovers. Our tech ran a camera inspection down the supply and return ducts and found the 2004 flexible runs had separated at two collars near the air handler, letting humid attic air bleed in, so we performed source removal under negative pressure with HEPA filtration, then sealed the joints and registers with Guardsman mastic and foil tape. The property passed its next management inspection and the musty odor did not return after a two-week vacancy. If the smell is coming from a contaminated evaporator coil or a dead animal in the duct, sealing alone won’t solve it. We diagnose before we quote. Call (361) 326-5060 for a camera inspection and honest assessment.
