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 Whitney
We’re the crew Whitney homeowners call when they want the job priced before we touch it and documented after we leave. Our dispatch office is in Las Vegas, but our technicians live and work in the Whitney area, so we know the 89122 ZIP and the subdivisions around Whitney Ranch and Russell Road well enough to spot the problems before we unload the van. If your system is pulling attic dust through a separated flex run or your utility bills have climbed without explanation, call us at (361) 326-5060. We’ll give you a written price and a 365-Day Done Right Promise on every repair.
Why Hollis Air Duct Cleaning Is Whitney’s Preferred Duct Sealing Company
We’ve been part of the Garrison Partners family since 2004, and our Whitney customers know what that means: a technician who shows up uniformed, background-checked, and inside the quoted window. Our phones are answered by a live person 24 hours a day, seven days a week, so you’re not waiting through a voicemail loop when your return is dumping dust into the hallway.
Whitney’s housing stock is almost entirely 1990s-to-2000s stucco tract homes with original flexible insulated duct runs, and we’ve sealed enough of them to know where the builder-grade mastic fails first. The Garrison Standard requires us to price in writing before any work starts, complete the job by the book, and leave the site clean. That discipline matters in a bedroom community where homeowners have already dealt with no-shows and price jumps from other trades.
Our equipment comes from Rotobrush, Nikro, and Abatement Technologies, the same brands commercial crews use. We don’t bring hardware-store gear into your attic.
Air Duct Sealing in Whitney
Air Duct Sealing in Whitney means reconnecting and sealing the flex-duct runs, plenum joints, and register boots that were installed during the tract-building boom and have been baking in 140°F+ garage attics ever since. A typical sealing job in Whitney runs $280 – $520 for a single system, with whole-home jobs on multi-system houses ranging $650 – $1,200 depending on access and the number of disconnected or degraded joints we find.
Most Whitney homes have short duct runs that are easy to access, which keeps labor costs predictable, but the near-continuous May-to-September runtime here means mastic dries and cracks faster than in milder climates. If your system has been running hard through multiple desert summers, the seals are likely degraded even if the ducts look intact from the register.
Per-System Pricing for Multi-System Homes
Many Whitney homes, especially larger builds near Whitney Ranch, have two or three separate HVAC systems. We price per system, not per house, because each system has its own trunk, plenum, and flex runs that need individual inspection and sealing. A single leaking trunk in a three-system house can defeat the whole job if the tech only seals what’s easy to see.
Camera and Pressure Documentation
Because you can’t see inside your attic or walls, we document every sealing job with before-and-after camera footage and static-pressure readings. You’ll know exactly what failed, where we sealed it, and that the system is holding pressure before we leave.
Duct Sealing Services in Whitney
Duct Sealing Services in Whitney address the specific failure modes of 1990s-to-2000s builder-grade flex-duct construction: slumped and disconnected runs in hot attics, cracked mastic at plenum connections, and separated joints pulling attic dust straight into your return. Our Duct Sealing team uses professional-grade mastic and mechanical fasteners, not tape, because tape fails in the temperature swings of a Mojave Desert attic.
The desert grit and monsoon-season dust storms that hit Whitney from July through September make sealed ductwork especially critical. Every gap in your system is an entry point for fine particulate that coats your evaporator coil and recirculates through your home. Sealing isn’t just about efficiency; it’s about stopping the dust load before it reaches your air handler.
Mastic Application and Joint Reconnection
We apply duct-sealing mastic, a thick, fiber-reinforced compound that remains flexible after curing, to every joint and seam. For disconnected flex runs, we reconnect with mechanical fasteners first, then seal with mastic. The builder-grade tape you may see on original installations has usually dried and failed after two decades of heat cycling.
Static-Pressure Verification
After sealing, we measure static pressure across the system to confirm the repair. A drop in return-side pressure after sealing indicates we’ve closed the leaks that were letting attic air into the duct. We record this number and explain it before we pack up.

Trusted Brands We Service in Whitney
We stock parts and sealing materials from Abatement Technologies, Guardsman, and Aprilaire, so Whitney customers aren’t waiting on a parts run to Las Vegas when a plenum boot or collar needs replacement. Our vans carry Rotobrush rotary systems and Nikro negative-air machines for jobs where cleaning and sealing go together. If your system uses Honeywell or Aprilaire filtration components, we can inspect and reinstall them correctly after the sealing work is complete. Fast turnaround matters in July when your system is running fourteen hours a day and every hour of downtime is uncomfortable.
Common Duct Sealing Problems We See in Whitney Homes
- Disconnected flex-duct joints in garage attics. The builder-grade flex runs in Whitney Ranch-area homes slump and pull apart in 140°F+ attic heat, creating a direct path for attic dust into your return. Homeowners often misread this as a dirty-system problem and schedule cleaning when sealing is the real fix.
- Cracked mastic at plenum and register boots. After two decades of near-continuous May-to-September runtime, the original mastic dries and shrinks, letting desert dust infiltrate the air handler. We remove the old material and apply fresh, fiber-reinforced mastic rated for high-temperature cycling.
- Sealed-up high-efficiency homes with masked leaks. Modern Whitney homes are built tight, which is good for efficiency but means a single leaking trunk in a multi-system house can pressurize the attic and defeat the whole job. We test and seal every trunk, not just the accessible ones.
- Monsoon-season dust infiltration through degraded seals. The July-September dust storms that sweep across the Mojave push fine particulate through any gap in your duct envelope. Post-storm, we see a spike in calls from Whitney homeowners whose systems are suddenly dumping dust through every register.
Pricing for Duct Sealing in Whitney, NV
A typical single-system duct sealing job in Whitney runs $280 – $520. Whole-home sealing on multi-system houses ranges $650 – $1,200. What moves the price: the number of systems, how many joints need reconnection versus simple resealing, attic access conditions, and whether we need to replace degraded boots or collars rather than just seal them.
We do not quote per-vent or per-linear-foot pricing because those models incentivize techs to find extra charges once they’re in your home. We give one flat price per system, agreed in writing before work starts, based on what we find during inspection. That price does not move at the door. Estimates are free, and we encourage you to get a second opinion if our number surprises you. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Whitney
Because most larger Whitney homes have two or three independent HVAC systems, each with its own trunk, plenum, and flex runs. A per-house price would force us to guess at the scope or cut corners on the third system. Per-system pricing means you pay for exactly what gets inspected and sealed, with a written price for each unit before we start. Call (361) 326-5060 and we’ll walk through your home’s layout.
We use a combination of camera inspection and static-pressure testing. The camera shows us disconnected or degraded joints; the pressure reading quantifies how much air is escaping. After sealing, we run both tests again and show you the before-and-after. You’ll have documentation of work you couldn’t see yourself. Call (361) 326-5060 to schedule an inspection.
In Whitney, yes, this is often a sealing problem, not a filter problem. We regularly find disconnected flex-duct joints in garage attics that pull 140°F attic dust straight into the return. The filter can’t catch what enters behind it. A camera inspection will show whether your return is sealed or drawing from the attic. Call (361) 326-5060 for a free estimate.
Yes. Sealed ducts prevent the fine desert dust and monsoon particulate from entering your system through gaps and cracks. In Whitney’s near-continuous summer runtime, every leak is an entry point for dust that coats your coil and recirculates through your home. Sealing reduces that load and takes strain off your filter and air handler. Call (361) 326-5060 before the July-September dust storms hit.
You should receive before-and-after camera footage, static-pressure readings, and a written invoice that details what was sealed on which system. We also provide the 365-Day Done Right Promise in writing: if any sealed joint fails within a year, we return and make it right at no charge, including a free second visit. Call (361) 326-5060 and we’ll explain exactly what documentation accompanies every job.
