Ocoee isn’t a generic Orlando suburb. This city grew fast from citrus country, and that history lives in its housing stock and its air. Homes here deal with fine organic debris from remaining groves, pollen loads from heavy oak canopy, and dust from unpaved roads and horse pastures that newer suburbs simply don’t face. Our technicians know the difference between sealing a 1980s rigid metal trunk in a ranch near Lake Apopka and working with flex duct in a 2010s build off Franklin Street. That local knowledge matters because the failure modes are different, and so are the fixes.

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

We’ve been in business since 2004, and our reputation in Ocoee is built on showing up inside the window, pricing in writing, and leaving the site clean. The Garrison Standard requires it. Our technicians are background-checked and uniformed, and you’ll know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops.

Our Orlando office dispatches crews to Ocoee daily, so we’re not driving from across the state or subcontracting to whoever’s available. We know the local conditions: the humidity that never really drops, the year-round AC runtime that vibrates flex duct connections loose, the organic debris that coats duct walls differently than construction dust. When we seal your ducts, we’re accounting for all of it.

The 365-Day Done Right Promise covers every job in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. No negotiation, no runaround. That’s The Garrison Standard, and it’s how we’ve operated since 2004.

Duct Repair in Ocoee

Duct Repair in Ocoee means fixing the physical damage that makes sealing impossible: separated joints, crushed flex runs, corroded metal, or ductwork that was never properly connected in the first place. We see this constantly in Ocoee’s older ranch homes, where original rigid metal trunks have shifted over decades and additions were cobbled on with mismatched materials. A typical duct repair in Ocoee runs $200 – $600 for joint reconnection or section replacement, with larger trunk repairs reaching $800 – $1,200 if accessibility is poor. We always inspect with a camera before quoting, so the price you get is the price you pay.

When Repair Comes Before Sealing

Sealing a broken duct is like caulking a cracked pipe. We repair first: reconnect separated trunks, replace collapsed flex, reinforce sagging runs. Only then do we seal. In Ocoee homes near the West Orange Trail, we regularly find return ducts pulling in dust through gaps that opened where metal meets flex. The repair is structural. The seal is what keeps it closed.

Additions and Renovated Spaces

Ocoee’s housing boom left many homes with ductwork that doesn’t match the floor plan. A converted garage, a bonus room, a mother-in-law suite, these often have flex duct that was never properly supported or connected to the main trunk. We repair those connections, then seal them so they don’t leak conditioned air into your attic or crawl space.

Air Duct Sealing in Ocoee

Air Duct Sealing in Ocoee closes the gaps, cracks, and disconnected joints that let conditioned air escape and unfiltered air enter your system. In Ocoee’s humid subtropical climate, this matters more than in drier regions. Every leak pulls hot, moist attic air into your ducts, forcing your AC to work harder and creating conditions for mold growth inside the system. A typical whole-home air duct sealing in Ocoee runs $350 – $850, with larger or multi-zone systems reaching $1,000 – $1,400. We use mastic and mesh on metal joints, proper collars and supports on flex connections, and we verify our work with static pressure tests.

Mastic vs. Tape: What We Use and Why

We don’t use duct tape. In Ocoee’s year-round AC runtime and high humidity, tape dries out and fails within months. We seal metal joints with mastic, a thick, flexible compound that hardens into a permanent bond, reinforced with mesh for larger gaps. Flex duct connections get proper mechanical collars and supporting straps so vibration doesn’t shake them loose again.

Static Pressure Verification

After we seal, we measure. Static pressure tells us how hard your blower is working to push air through the system. A good seal should drop that number. We show you the before and after. If the pressure hasn’t improved, we find the leak we missed. That’s The Garrison Code: verify, don’t assume.

Trusted Brands We Service in Ocoee

Our Duct Sealing crews arrive with professional-grade equipment: Rotobrush rotary brush systems for agitation cleaning inside ducts, Nikro negative-air machines for source removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t use hardware-store vacuums or consumer-grade sealants. For Ocoee homeowners, that means we stock the parts and materials to complete most jobs in one visit, without waiting on special orders. If your system uses Abatement Technologies filtration or Guardsman media, we carry compatible components. Fast turnaround matters when your AC is running ten months a year.

Common Duct Sealing Problems We See in Ocoee Homes

• Register-only sealing misses the real leaks. Some crews seal the visible supply registers and call it done, leaving return-side gaps near the air handler wide open. In Ocoee, where unpaved roads and groves generate fine dust, those return leaks pull contaminants straight into your system. We seal both sides.
• Flex duct vibrates apart in constant AC runtime. Ocoee’s climate means air conditioning runs nearly year-round. That vibration loosens tape and unsupported flex connections. We use mechanical collars and proper strapping, not adhesive shortcuts.
• Additions and outbuildings were never properly connected. Many Ocoee homes have converted garages, bonus rooms, or detached workshops with ductwork that was added after the original build. The connections to the main trunk are often leaking or missing entirely. We trace, repair, and seal every run.
• Organic debris creates paste-like coatings that hide gaps. Because Ocoee still has active citrus groves and horse pastures around Lake Apopka and the West Orange Trail, ducts here collect fine organic debris and pollen that sticks to flex duct walls more aggressively than the construction dust found in newer Orlando suburbs. That grit combines with year-round AC humidity to create a paste-like coating that can only be removed with agitation tools and negative pressure source removal, not a shop vac. We clean before we seal, so the mastic bonds to duct, not grime.
