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 Highland Village
We’re the crew Hollis Air Duct Cleaning sends to Highland Village when a heat pump’s working overtime but the bedrooms upstairs still won’t cool. Dispatch runs out of our Dallas-Fort Worth office, and our trucks cover Highland Village regularly, so we’re not guessing about the flex-duct layouts in your attic or the pollen load that blows off Lake Lewisville every March. If your ducts are leaking conditioned air into unconditioned space, you’re paying to cool your attic. Call (361) 326-5060 and we’ll get you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Highland Village’s Preferred Duct Sealing Company
We’ve been working Highland Village homes since long enough to know the difference between a 1987 two-story off Justin Road and a 1960s ranch on Lakeside Drive. The Garrison Standard means we arrive inside the quoted window, price it in writing, and leave the site clean. Our technicians are background-checked and uniformed; you’ll know who’s walking in before they get there.
Phones get answered by a live person, 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday when your upstairs is 84 degrees.
Every repair we make carries the 365-Day Done Right Promise in writing. If the seal fails or the joint separates within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan; it’s on the paperwork.
We know Highland Village’s housing stock: the all-electric heat pump suburbs built in the 1980s through 2000s, the original Lakeside Drive ranches with their tighter chases, and the lake-facing homes in Highland Shores where north- and east-facing returns take the worst of the oak pollen. That local knowledge changes where we look first.
Air Duct Sealing in Highland Village
Air Duct Sealing in Highland Village means finding and closing the gaps, separations, and crushed sections in your ductwork so the air your heat pump conditions actually reaches the rooms you live in. Most Highland Village homes built from the 1980s through the 2000s run flex duct through unconditioned attics to serve upstairs bedrooms, and those long spans separate at joints, crush where they sag, or pull loose from registers. We seal with mastic and mesh, pressure-test where possible, and target the runs that lose the most air. A typical Air Duct Sealing job in Highland Village runs $450 – $850 for a standard two-story home, depending on how many joints need attention and whether we need camera access to find hidden separations.
Heat Pump Systems and Duct Load
Highland Village’s all-electric housing stock pushes heat pumps harder than gas-furnace suburbs next door. Heat pumps move more air volume per BTU, so duct leaks cost you more in runtime and wear. We size our sealing approach to the system’s static pressure, not just the hole size.
Camera Inspection Before Sealing
We don’t guess where the leak is. Our Rotobrush camera systems let us see inside flex trunk lines and rigid chases before we commit to a sealing plan. In older Lakeside Drive ranches, that step saves time and keeps us from sealing over a joint that’s actually disconnected behind a wall.
Duct Sealing Services in Highland Village
Duct Sealing Services in Highland Village cover more than slapping tape on a register boot. We pressure-test the system, identify the worst leakage points with visual and camera inspection, seal accessible joints with mastic and fiberglass mesh, and recommend where duct replacement makes more sense than sealing. For a typical Highland Village home, our Duct Sealing Services range from $450 for targeted sealing of known problem runs to $1,200 for whole-system sealing with pressure verification. Homes near Lake Lewisville in Highland Shores or the Lakewood area often need additional return-side attention because oak and cedar pollen loads accelerate joint degradation where humidity keeps particles stuck to duct walls.
Mastic and Mesh Sealing
We use duct-sealing mastic, not foil tape, on every joint we can reach. Mastic stays flexible, handles the temperature swings in your attic, and doesn’t peel when Highland Village’s summer humidity hits. We reinforce with fiberglass mesh on larger gaps so the seal holds through expansion and contraction cycles.
Pre-Filter Sock Installation
For north- and east-facing returns in lake-adjacent neighborhoods, we install pre-filter socks after sealing to protect the new work. The sock catches pollen before it hits the duct wall, extending the seal’s life and reducing how often you need us back.

Trusted Brands We Service in Highland Village
We carry professional-grade equipment and materials on every truck: Rotobrush rotary brush systems and camera inspection tools, Nikro negative-air machines for controlled debris removal, and filtration products from Honeywell, Aprilaire, and Guardsman. For Highland Village homeowners, that means we don’t order parts and make you wait. We stock the mastic, mesh, pre-filter socks, and register boots that match your system’s era and configuration. If your 1990s flex trunk needs a compatible wye or transition fitting, we’ve likely got it. Fast turnaround matters when your heat pump’s running 14 hours a day in July and the upstairs still won’t cool.
Common Duct Sealing Problems We See in Highland Village Homes
- Flex duct separations in unconditioned attics. The original 1980s – 2000s installs in Highland Village’s two-story homes run long flex spans to upstairs bedrooms, and those connections separate or crush where they sag over time. The heat pump’s air handler pressurizes the attic instead of the register.
- Pollen-loaded returns mistaken for leaks. North- and east-facing returns near Lake Lewisville clog with oak and cedar pollen each spring because lake humidity sticks fine particles to duct walls. Homeowners sometimes seal over ducts that are actually just loaded with debris, making airflow worse.
- Hidden disconnections in older ranch chases. The 1960s-era homes near Lakeside Drive have tight duct chases and short, rigid runs where joints disconnect behind walls or under insulation. A standard duct-sealing pass can’t reach them without camera inspection and agitation tools first.
- Crushed flex at wye joints from original installs. In Highland Shores and similar neighborhoods, the 1990s flex trunk lines to second-story registers often crush where they branch at wye fittings, especially if the original installer left too much slack or too little support.
Pricing for Duct Sealing in Highland Village, TX
We don’t do per-vent teaser prices that balloon once the van is in your driveway. We quote one flat price per system, agreed in writing before any work starts. For Highland Village, typical Duct Sealing runs $450 – $850 for targeted sealing of accessible joints in a standard two-story home, and $850 – $1,200 for whole-system sealing with pressure verification and camera inspection. Older Lakeside Drive ranches with tight chases or homes needing extensive return-side work near the lake may run toward the higher end. What moves the price: how many joints need sealing, whether we need camera access to find hidden separations, if returns need pre-filter sock installation, and whether any flex sections need replacement rather than sealing. Every estimate is free. Call (361) 326-5060 and we’ll give you a written number you can hold us to.

FAQs About Duct Sealing in Highland Village
Every three to five years for a typical Highland Village home, but every two to three if you’re lake-adjacent in Highland Shores or Lakewood where oak and cedar pollen loads are heavier. Heat pumps move more air than gas furnaces, so duct joints work harder and separate faster. Call (361) 326-5060 to schedule a free inspection and we’ll tell you if your system needs sealing now or can wait.
The flex trunk line to your second-story registers has likely separated at a joint or wye fitting in the unconditioned attic, so your heat pump is cooling the attic instead of the bedrooms. Duct cleaning won’t fix a separation; sealing or reconnection will. We see this exact failure in Highland Village’s 1980s – 2000s two-story stock regularly. Call (361) 326-5060 and we’ll camera-inspect to confirm.
Yes. Lake humidity makes oak and cedar pollen stick to duct walls instead of passing through, so north- and east-facing returns in Highland Shores and Lakewood clog faster and hold moisture that degrades joints. We target those specific runs for sealing and recommend pre-filter socks to protect the work. The pollen corridor off the lake is real, and it changes where we look first.
It is, but it takes a different approach. The tight duct chases and short rigid runs in Lakeside Drive ranches hide disconnected joints that a standard sealing pass can’t reach. We use camera inspection and rotary brush agitation to find and access those points before we seal. The work is often more surgical than in newer homes, but the results are the same: air goes where it’s supposed to.
Your upstairs bedrooms should cool within one cycle of the thermostat setting, supply registers should feel stronger, and your heat pump should run fewer hours to maintain temperature. We verify with before-and-after static pressure readings where accessible, and we show you the camera footage of the sealed joints. If the seal fails within a year, the 365-Day Done Right Promise covers a free return visit. Call (361) 326-5060 if you’re not seeing improvement within a week.
