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.

AfterFast, Reliable Duct Sealing Across Trophy Club
Duct sealing in Trophy Club typically runs $400 – $900 per HVAC system depending on the extent of leakage, and most jobs are scheduled within a few days with a written price locked in before any work starts. We’re the Duct Sealing team at Hollis Air Duct Cleaning, and we’ve been working in the master-planned neighborhoods around Trophy Club Country Club long enough to know what fails here and why. Our dispatch is coordinated from the Dallas-Fort Worth office, but the crews that roll into Trophy Club are local to the area and familiar with the two-story, multi-zone homes that dominate this town. Call us at (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Trophy Club’s Preferred Duct Sealing Company
We’ve built our reputation in Trophy Club on showing up inside the quoted window, pricing in writing, and leaving the site clean. That’s The Garrison Standard, and it’s how every Hollis location operates independently.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. And when you call (361) 326-5060, a live person answers the phone, 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday for a scheduling question.
Every duct sealing job we do in Trophy Club comes with the 365-Day Done Right Promise in writing. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. Roy Castellanos, who leads Hollis Air Duct Cleaning, put that guarantee in place because he knows homeowners here can’t afford to chase down a crew that disappears after the invoice is paid.
We also understand the local housing stock. Trophy Club’s homes, mostly built from the 1980s through the early 2000s, average 2,500 – 5,000 square feet with multiple HVAC zones and long flex-duct runs in vented attics. That matters because a technician who treats a three-system house like a single job will miss the upstairs return plenum that’s pulling loose while sealing only the downstairs trunk. We don’t do that. We scope and price per system, check each zone separately, and document everything.
Duct Repair in Trophy Club
Duct Repair in Trophy Club addresses the physical damage that happens when flex duct degrades, connections separate, or rodents and moisture compromise the ductwork in your attic. Most Trophy Club homeowners need duct repair when they notice hot rooms upstairs, dust blowing from registers, or their energy bill climbing without explanation. A typical duct repair in Trophy Club runs $250 – $600 per location, depending on whether we’re reattaching a loose plenum, replacing a collapsed flex run, or repairing a damaged trunk line.
Return Plenum Reattachment
The return plenum is the box that connects your air handler to the ceiling ductwork. In Trophy Club, we regularly find this joint has pulled loose after a July of 140°F attic heat expansion. We remove the damaged tape or failed sealant, reseat the plenum on the boot, then seal the joint with mastic rated for extreme attic temperatures.
Flex Run Replacement
When a long flex-duct run behind a knee wall has collapsed, torn, or filled with black clay dust, patching isn’t enough. We cut out the damaged section and install new insulated flex duct with proper support straps and sealed connections, then test the full run for leakage.
Air Duct Sealing in Trophy Club
Air Duct Sealing in Trophy Club closes the gaps, seams, and connection points where conditioned air escapes into your attic and unconditioned air gets drawn back into your system. Trophy Club homeowners usually call for sealing when rooms won’t stay cool in August, when dust seems to reappear within hours of cleaning, or when their HVAC runs constantly without reaching the thermostat setpoint. A typical air duct sealing job in Trophy Club costs $400 – $900 per HVAC system, with most two-story homes falling in the $800 – $2,700 range total because they have two or three separate zones.
System-by-System Pressure Testing
We don’t guess. After sealing each zone, we run the blower motor and check supply and return ducts with a pressure differential test to confirm leakage has dropped. You get the numbers in writing.
Attic-Grade Materials
Trophy Club attics exceed 140°F in summer. We use mastic and foil tape rated for those conditions, not the hardware-store products that turn brittle and fail within a season. Our equipment includes professional-grade tools from Rotobrush and Abatement Technologies.
Trusted Brands We Service in Trophy Club
We carry parts and filtration products from Honeywell, Aprilaire, and Guardsman, so Trophy Club homeowners aren’t waiting on a special order when their system needs attention. Our rotary brush systems from Rotobrush and negative-air machines from Nikro are the same tools commercial crews use, and we explain what each piece does while we’re working. That means faster turnaround on repairs and replacements, and no delays because a technician has to drive back to a warehouse across the metroplex. If your ductwork uses proprietary fittings or specific filtration components, we likely stock them or can source them by the next business day.
Common Duct Sealing Problems We See in Trophy Club Homes
- The visible-first mistake. Some crews seal only the first 10 feet of flex duct at the air handler, where it’s easy to reach, while the long attic runs behind knee walls go untouched. That’s where the real leakage lives in Trophy Club’s 2,500 – 5,000 square foot homes.
- The single-price trap. A three-zone house gets quoted one flat number, then the crew seals the downstairs zone and leaves because they’re out of time. The upstairs return plenum stays loose, pulling 140°F attic air into the system all summer.
- Wrong materials for the climate. Standard duct tape and basic mastic fail within a season in Trophy Club attics. We use products rated for the actual temperatures your ducts experience, not the conditions they see in a milder climate.
- Missing documentation. Homeowners can’t climb into their attic to verify the work. We provide before-and-after pressure readings, photos of sealed joints, and a written scope for each system so you have proof the job was done completely.
Pricing for Duct Sealing in Trophy Club, TX
A typical duct sealing job in Trophy Club runs $400 – $900 per HVAC system. Most homes here have two or three systems, so total project costs usually fall between $800 and $2,700. What moves the price: how many zones your home has, how accessible the ductwork is in your attic, whether we’re sealing existing connections or replacing damaged flex runs, and whether the return plenum has pulled loose and needs reattachment.
We do not quote per-vent pricing. That’s the teaser-rate game that turns a $199 coupon into a $1,800 invoice once the technician is inside. We give one flat price per system, agreed in writing before any work starts. The price does not move at the door. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Trophy Club
Yes, we seal all three, but we scope and price each system separately. A three-zone house gets three separate sealing scopes, three blower-door-style pressure checks, and three documentation packets. Sealing the upstairs 5-ton zone tells you nothing about the downstairs zone, so we don’t lump them into one vague quote. Call (361) 326-5060 and we’ll walk through your system layout.
North Texas attic temperatures exceed 140°F in July, and the expansion and contraction of metal and flex materials over a hot summer separates the plenum from the boot. It’s the classic Trophy Club failure mode. We reattach with mechanical fasteners and seal with mastic rated for extreme heat, then check it under blower pressure before we leave.
You get before-and-after pressure readings for each system, photos of the sealed joints, and a written scope of what was done. If we ran a camera inspection up a flex run, you get those images too. The 365-Day Done Right Promise is included in writing. If anything fails within a year, we return at no charge.
It matters because leaky return ducts pull unfiltered attic air into your system, and that attic air carries the fine pollen and black clay dust that coats Trophy Club in spring. Sealing the return side is as important as sealing supplies. A tight duct system means your filtration actually has a chance to work.
We run the blower motor and measure pressure differential on each zone after sealing. The numbers tell the story. We also do a visual and camera inspection of critical joints like the plenum-to-boot connection. You’ll see the before-and-after readings in your documentation packet before we pack up.
