Fast, Reliable Duct Sealing Across Enterprise
Duct sealing in Enterprise typically runs $450 to $1,400 depending on system size, accessibility, and how much of the original ductwork has failed. Most jobs are finished in a single day. If you’re losing cooled air into a hot attic or watching dust coat your registers a week after cleaning, the problem is usually a leaky duct run, not your AC unit. Call Hollis Air Duct Henderson at (775) 383-5847 and we’ll schedule a camera inspection with a written price before any work starts.
We work in Enterprise every week. Our crews know the tract-home layouts off Blue Diamond Road, the single-story spreads near the M Resort, and the newer subdivisions pushing south toward the Henderson line. That local familiarity matters, because Enterprise homes share a specific failure pattern: original flex ducts in slab-foundation attics that bake apart under Mojave heat. We find the leaks fast because we know exactly where to look.
Why Hollis Air Duct Henderson Is Enterprise’s Preferred Duct Sealing Company
We have been sealing ducts since 2004 as part of the Garrison Partners family, and we operate under a standard most competitors will not put in writing. Every job gets a written price before work begins. The price does not move at the door. And the work is covered by our 365-Day Done Right Promise: if a sealed joint fails within a year, we return and fix it at no charge, including a free second visit. That guarantee is written on your invoice, not implied over the phone.
Our technicians are background-checked and uniformed, so you know who is walking into your home before they arrive. They follow the Garrison Code: arrive inside the quoted window, explain what they found in plain English, complete the job by the book, and leave the site clean. No mystery charges, no hauling debris out of your attic and calling it an upgrade. Roy Castellanos runs our crew, and he holds every tech to that standard.
When you call, a live person answers. That’s 24 hours a day, 7 days a week. You will not leave a voicemail and wait until Monday for a callback. If your AC is running nonstop and your living room is 82°F in July, you need someone on the phone now, not a queue.
Styles & brands we work with
Duct Insulation in Enterprise
Duct insulation in Enterprise is a repair we perform constantly, because the original fiberglass wrap on flex ducts degrades in attic heat that routinely exceeds 130°F. When the wrap tears or falls away, the cooled air inside the duct picks up heat before it reaches your registers. Your AC works harder, your rooms stay warm, and your power bill climbs. Reinsulating a typical Enterprise single-story home runs $300 to $800 depending on how many runs need re-wrapping.
Why Attic Heat Kills Duct Insulation
A composition shingle roof over a slab-foundation tract home absorbs solar radiation all day. With over 300 days of sunshine in Enterprise, that heat transfers into the attic cavity and bakes everything inside it. Fiberglass duct wrap dries out, loses its binding, and eventually slides off the flex core. What remains is a bare duct transferring attic heat straight into your conditioned air. We see it on nearly every pre-2010 home we inspect in Enterprise.
What Reinsulation Actually Fixes
New duct insulation to code restores the thermal barrier between your conditioned air and the attic. It also prevents condensation from forming on cold duct surfaces during the humid weeks of late summer. That condensation is what soaks through drywall and causes the water stains some Enterprise homeowners mistake for roof leaks. The fix is the duct wrap, not the shingles.
HVAC Duct Sealing in Enterprise
HVAC duct sealing in Enterprise means closing the air leaks in your supply and return runs so the air your furnace or air handler pushes actually reaches your rooms. Typical whole-system sealing in Enterprise runs $450 to $1,400. The work involves locating every joint, collar, and plenum connection, then sealing them with mastic or UL-rated tape designed for the temperature swings of a Mojave attic. The payoff is immediate: more air at the registers, less runtime on the compressor, and less dust pulled in from the attic or crawlspace.
Sealing Before You Replace the AC
If you are replacing an air conditioner in Enterprise, seal the ducts first. A new 16-SEER unit attached to leaking ductwork delivers roughly the same room temperatures as your old unit, because a third of the cooled air is dumping into the attic. We regularly seal existing duct systems ahead of HVAC replacements so the new equipment performs to its rated efficiency. The sealing job is a fraction of the equipment cost and it is the difference between a system that cools and one that runs all day.
Return Duct Collapse in Enterprise Attics
Enterprise has a failure mode most other parts of the valley rarely see: collapsed return ducts. The original silver flex duct used in 1990s and early 2000s tract homes has an inner liner that delaminates from the outer jacket after years of attic heat. Once the liner separates, the negative pressure from the air handler sucks it flat, choking return airflow. The AC runs continuously but the house never cools. We find this in Silverado Ranch and other Enterprise subdivisions regularly, and the fix requires replacing the failed run, not just sealing a joint.
Trusted Brands We Service in Enterprise
We stock sealing materials and filtration products from Honeywell, Aprilaire, and Guardsman, so we are not making a second trip to the supply house when your job is scheduled. Honeywell media filters and Aprilaire air cleaners pair well with sealed ducts in Enterprise because they trap the fine dust that blows in from the Mojave and would otherwise coat your evaporator coil between cleanings. Guardsman components give us access to heavier-gauge registers and collars when original equipment has rusted or cracked in attic heat. We explain what each part does and why it matters, in plain terms, before we install it.

AfterCommon Duct Sealing Problems We See in Enterprise Homes
- Factory tape and mastic peeling inside the attic. The original install crews used materials that were never meant to survive 130°F attic temperatures year after year. The tape dries, the mastic cracks, and the joints open up. Cooled air leaks into the attic, and the system runtime creeps up.
- Wind-blown dust infiltrating unsealed return joints. Enterprise sits downwind of open Mojave land, and that fine dust finds every gap in a return duct. It coats the blower motor, packs the evaporator coil, and chokes filter life. Sealed returns stop the dust at the source.
- Outbuilding duct runs pulling in gravel-road dust. Homes on the southern and western edges of Enterprise often have casitas or workshop builds with separate duct runs tied into the main plenum. Those connections are frequently left unsealed or sealed with a single wrap of tape. Gravel-road dust gets pulled in and buries the registers in a fine gray film.
- Collapsed flex-duct liners starving the air handler. As noted above, heat delamination causes original flex duct to suck closed. This is not a slow leak; it is a total airflow failure. The AC runs nonstop, the house stays hot, and the compressor works against a closed airway. Camera inspection catches it in minutes.

FAQs About Duct Sealing in Enterprise
Duct sealing is not a maintenance item you repeat on a schedule. Properly sealed ducts with mastic and UL-rated tape should hold for 10 to 15 years. The reason Enterprise homeowners need sealing more often than other parts of the valley is that the original install work from the 1990s and early 2000s used materials that fail in attic heat, and the first failure usually shows up within 8 to 12 years. Call (775) 383-5847 and we can camera-inspect your ducts and tell you exactly what has failed and what still holds.
Yes, and this is one of the most common calls we get from homeowners on the unpaved edges of Enterprise. Unsealed return ducts pull air from the attic or crawlspace, and that air carries the same fine dust that blows off the open Mojave. Seal the returns and the dust stops entering through the ductwork. What still enters through open windows and door gaps is a separate issue, but sealing the returns removes the constant low-grade dust loading that coats your registers and clogs your filter.
Enterprise’s housing stock skews to tract homes built from the late 1990s through the 2010s, and those builds used a generation of flex duct that delaminates under sustained heat. Older Las Vegas neighborhoods often have metal duct or a different flex product that holds up better. Add in Enterprise’s slab foundations, which push all ductwork into the attic rather than a basement or crawlspace, and you get the highest-temperature duct environment in the valley. The failure is thermal, not age.
Seal before, or at the same time. A new AC unit connected to leaking ducts will not deliver the efficiency you paid for, and the manufacturer’s SEER rating assumes a tight duct system. We regularly seal existing ducts ahead of HVAC replacements in Enterprise so the new equipment starts life moving air through a system that holds it. If you only have budget for one thing, seal the returns first: that is where the dust infiltration and airflow starvation happen.
Yes. The dust that coats your evaporator coil is air carrying particulates into the return side of the system. Sealed returns with properly fitted filters stop most of that dust before it reaches the coil. We use Aprilaire and Honeywell filtration products in Enterprise homes specifically because they fit tightly in the filter cabinet and catch the fine Mojave dust that passes through cheap fiberglass filters. Call (775) 383-5847 and we will check your return runs, your filter fit, and your coil condition in one visit.
