Duct Sealing in Horizon West - Tested First, Written Price Second

Fast, Reliable Duct Sealing Across Horizon West

Duct sealing in Horizon West typically runs $350 – $850 for a whole-home system, and most jobs are completed in a single visit with a written price locked in before we start. If your Horizon West home was built after 1995, there’s a strong chance the original builder-grade seals around your registers, boots, and air handler are already failing, letting humid attic air bleed into your conditioned space and driving up your cooling costs.

Why Hollis Air Duct Cleaning Is Horizon West’s Preferred Duct Sealing Company

We’ve been in business since 2004 as part of the Garrison Partners family, and that track record matters in a market where many competitors have come and gone.

Our response time to Horizon West is typically same-week, not because we rush, but because we keep crews routed through Orange County regularly. We don’t play the “estimate game” where the price shifts once we’re in your attic. The price is written down before any work starts, and it does not move at the door.

Our technicians carry professional-grade equipment from Rotobrush and Abatement Technologies, and we stock sealing products including Guardsman filtration components for fast turnaround on Horizon West jobs. Every repair is backed by our 365-Day Done Right Promise: if the work fails within a year, we return and make it right at no charge, including a free second visit.

Duct Sealing Services in Horizon West

Duct Sealing Services in Horizon West focus on closing the gaps, leaks, and disconnected joints in your forced-air system that waste cooled air and pull humid attic air into your living space. Because nearly every home here was built after 1995 with flexible ductwork running through hot attics, the seals around boots, collars, and the air handler cabinet are the weakest points. We typically see these jobs run $350 – $650 for targeted sealing of accessible leaks, and $600 – $850 for whole-system sealing with full documentation. Most Horizon West homeowners call us when rooms won’t hold temperature, energy bills spike, or they notice musty smells from the vents, especially after Central Florida’s afternoon thunderstorms drive humidity even higher.

Leak Detection and Mastic Sealing

We pressurize your duct system and use smoke pencils and infrared cameras to find every leak, not just the obvious ones. Then we seal with duct mastic, the thick, flexible compound that outlasts foil tape by years in Horizon West’s attic heat. Mastic stays pliable, so it won’t crack as your ducts expand and contract through our long cooling season.

Warranty-Compliant Documentation

Because many Horizon West homes are still under original builder warranties, we photograph before-and-after conditions, record static pressure readings, and provide a written report formatted for warranty submission. This matters. We’ve seen homeowners denied warranty coverage on HVAC failures because their prior duct work wasn’t documented by a licensed professional.

Duct Insulation in Horizon West

Duct Insulation in Horizon West addresses the sweating, condensation, and thermal loss that happen when cool air moves through uninsulated or poorly insulated flex ducts in 140-degree attics. Even perfectly sealed ducts will bleed efficiency if the insulation jacket is compressed, torn, or inadequate for Florida’s climate. We typically price duct insulation at $400 – $750 for partial rewrap of damaged sections, and $800 – $1,400 for full attic duct insulation with vapor-barrier jacketing. Horizon West homeowners need this most when they see water stains on ceiling drywall below duct runs, or when their HVAC runs constantly but never reaches setpoint.

Vapor-Barrier Jacket Replacement

Original flexible duct insulation in 2010s and 2020s Horizon West builds often uses thin vapor barriers that tear on truss edges or degrade from UV exposure in attic light. We replace with rated jacketing that blocks moisture migration, because in Central Florida’s humidity, a duct that sweats is a duct that grows mold.

Compression Recovery and Support

Crushed flex duct is common in Horizon West attics where installers laid runs across truss chords without proper support. We rehang to manufacturer pitch specifications, then reinsulate the full length. A crushed 8-inch duct performs like a 5-inch duct, your system works harder, and your warranty coverage can void if the original installer finds unsupported runs.

Trusted Brands We Service in Horizon West

We stock parts and sealing products from Aprilaire, Abatement Technologies, and Guardsman for Horizon West homeowners, which means no waiting on special orders for most jobs. Aprilaire’s ventilation controls integrate with the Honeywell systems we see in many local builds, and Abatement Technologies’ HEPA filtration matches the negative-air equipment we use during duct cleaning and sealing prep. Guardsman filtration products handle the fine citrus-grove sand and organic debris that’s distinctive to this area’s soil. When your job needs a specific boot size, collar adapter, or mastic compound, we likely have it on the van. That keeps our turnaround fast and our pricing predictable.

Common Duct Sealing Problems We See in Horizon West Homes

• Builder-grade foil tape failure. The foil tape and thin mastic applied around registers and boots in production-built Horizon West homes dries out and peels within three to five summers of attic heat exposure. We remove the failed material entirely and reseal with rated duct mastic that flexes instead of cracking.
• Crushed flexible duct runs. Flexible duct installed in 2010s and 2020s Horizon West attics is frequently crushed or kinked where it passes over trusses or gets pinched by stored items. Sealing a leaky boot while leaving the restriction just moves the problem downstream, so we always inspect the full run.
• Construction debris hiding gaps. Because Horizon West sits atop former citrus groves and wetlands, thunderstorm-driven fine sand and organic debris coat duct interiors and can hide gaps until a camera inspection. A seal-only job without prior source removal traps grit against fresh mastic and guarantees premature failure.
• Drywall dust and sawdust accumulation. In the Lakeside Village and Summerlake subdivisions off Avalon Road, our tech pulled a crushed, disconnected supply run off the air handler in a new-build attic and found it packed with drywall dust, sawdust, and citrus-grove sand the builder never source-removed before handover; we HEPA-vacuumed under negative pressure, resealed the collar and boot with mastic, and the homeowner’s rooms finally held temperature on the same Honeywell setpoint.
