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 Reno
Duct sealing in Reno typically runs $800 – $2,400 for a whole-home system, and most jobs finish in a single visit. We dispatch crews from our Dallas-Fort Worth scheduling office, which means we’re on the road to Reno within hours of your call, not days. Our Duct Sealing team knows the ranch-style homes along Farm-to-Market 118 and the older subdivisions near the Lamar County line, where original sheet-metal ductwork has been pulling attic air and field dust into living rooms since the 1970s. If your vents blow weak, your upstairs never cools, or your energy bill climbed last summer without explanation, leaking ducts are the likely culprit. Call (361) 326-5060 for a free estimate. We’ll put the price in writing before any work starts.
Why Hollis Air Duct Cleaning Is Reno’s Preferred Duct Sealing Company
We’ve been serving North Texas since 2004 as part of the Garrison Partners family, and our crews have sealed ducts in enough Reno homes to know what to expect before we open the attic hatch. Most of our Reno calls come from homeowners between 35 and 65 who bought an older ranch house and discovered the hard way that the previous owner never touched the ductwork. They are tired of teaser quotes that balloon once the technician is inside. We don’t work that way. The price is written down before we touch anything, and it doesn’t move at the door.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. That’s The Garrison Standard, and it applies to every Duct Sealing in Reno job we take. If the seal fails within a year, we come back and make it right at no charge under our 365-Day Done Right Promise. No negotiation, no runaround. Roy Castellanos built this operation on the belief that a written guarantee should mean something in a small town where everybody knows your name.
Phones are 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 AC is blowing 90-degree air through a gap in the attic trunk line.
Duct Insulation in Reno
Duct Insulation in Reno addresses a problem most homeowners don’t know they have: uninsulated or poorly insulated sheet-metal ducts running through 140-degree attics during July and August, bleeding cooled air into the roof space before it ever reaches your bedroom. In Reno’s humid subtropical climate, where air conditioners run hard from May through September, this is not a minor efficiency loss. It is the difference between a system that keeps up and one that runs all afternoon while the house never reaches the thermostat setting. A typical duct insulation job in Reno runs $600 – $1,800 depending on attic accessibility and linear footage.
When Attic Heat Wins
We see this constantly in the single-story ranch homes built between the 1950s and 1980s that dominate Reno’s housing stock. The original sheet-metal trunk lines were never wrapped. After forty years, the thin fiberglass that was there has compressed to nothing. We install fresh insulation rated for North Texas temperature extremes, sealed at every joint with mastic, so your conditioned air stays conditioned.
Condensate and Mold Risk
Reno’s humidity means cold ducts in hot attics sweat. That moisture soaks old insulation, destroys its R-value, and creates the conditions for mold growth. We strip out water-damaged material, treat the metal, and install closed-cell insulation that doesn’t absorb moisture. You’ll see the difference on your next electric bill, and you’ll smell the difference in air that doesn’t carry a musty attic note.
HVAC Duct Sealing in Reno
HVAC Duct Sealing in Reno is the single most cost-effective upgrade most homeowners can make to an older system, and it is almost always overlooked. The sheet-metal and flex duct installed in Reno’s ranch homes between the 1950s and 1980s was joined with tape that has dried, cracked, or fallen off entirely. Add-on rooms built in the 1990s and 2000s often used flex duct that is prone to tearing and rodent intrusion. The result is conditioned air leaking into attics, crawl spaces, and wall cavities, while unfiltered outdoor air gets pulled in through return gaps. A typical whole-home HVAC duct sealing job in Reno runs $800 – $2,400, with most falling in the $1,200 – $1,800 range for a 1,500 – 2,500 square foot home.
Pressure Testing Before and After
We don’t guess. Our crews use a duct blaster or calibrated pressure fan to measure leakage in CFM25 before we start and after we finish. The difference is documented on your invoice. In Reno, where original ductwork often leaks 30 – 40 percent of total airflow, a proper seal can drop that below 10 percent. That is not a marketing claim. That is what the gauge reads.
Mastic, Not Tape
We seal joints with duct sealing mastic, a water-based compound that remains flexible for decades and bonds to metal and flex duct alike. It is slower to apply than foil tape, and that is why cheaper crews don’t use it. We also handle Air Duct Cleaning in Reno for homeowners who want the full system addressed, and Dryer Vent Cleaning in Reno for fire safety and efficiency.
Trusted Brands We Service in Reno
Our trucks carry professional-grade equipment from Nikro, Honeywell, and Aprilaire, the same tools commercial HVAC crews use in Dallas and Fort Worth. For Reno homeowners, this means we don’t order parts from a catalog and make you wait. We stock sealing mastics, insulation wraps, and register boots sized for the older systems common in Lamar County. Our negative-air machines from Nikro keep your home clean while we work in the attic. Honeywell and Aprilaire filtration components integrate with sealed duct systems to maintain the pressure balance we just restored. Fast turnaround matters in a rural market where the next available crew might be two counties away.
Common Duct Sealing Problems We See in Reno Homes
- Original tape failure on 1960s – 1980s sheet metal. The cloth-backed tape used when your ranch house was built has turned to powder. We find entire trunk lines held together by gravity and dust. Every joint needs mastic, and many need mechanical reinforcement.
- Flex duct tears from rodents and age. The flexible duct added for back porches and garage conversions is thin-walled and vulnerable. Reno sits in agricultural country, and field mice find attic gaps. We replace damaged sections with insulated flex rated for the application, not hardware-store patch kits.
- Cotton dust accumulation after harvest season. Local technicians know that after cotton harvest in the fall, fine dust from nearby fields coats everything, including duct interiors and filter media. This accelerates tape degradation and increases static pressure, which forces more air through existing gaps. Sealing before harvest season prevents the worst of it.
- Unsealed return plenums pulling attic air. In Reno’s older homes, the return air path is often a framed chase or the wall cavity itself, open to the attic at the top. Your system recirculates 140-degree attic air mixed with whatever insulation fibers and rodent debris are up there. We seal these paths properly or recommend ducted returns.
Pricing for Duct Sealing in Reno, TX
Whole-home duct sealing in Reno typically costs $800 – $2,400. Most single-story ranch homes in the 1,500 – 2,500 square foot range fall between $1,200 and $1,800. Smaller partial seals or single-zone repairs can run $400 – $800. Duct insulation, when done with sealing, adds $600 – $1,800 depending on linear footage and attic accessibility.
What moves the price: the amount of accessible ductwork, the condition of existing joints, whether flex duct needs replacement, and whether we are sealing only the supply side or both supply and return. Attic temperature and clearance affect labor time. We do not quote per-vent or per-register. We price the whole system, write it down, and that is what you pay. No add-ons at the door. Call (361) 326-5060 for a free estimate. We’ll inspect your attic, explain what we found, and give you a written price before any work begins.

We seal ducts throughout Reno and the surrounding rural addresses along Farm-to-Market 118 and the county roads north and east of town. Whether you are in the original town plat or on acreage outside city limits, we come to you. Distance does not change our pricing structure.
We do not promise same-day dispatch for duct sealing, which is a scheduled improvement job, not an emergency repair. However, our phones are answered by a live person 24/7, and we will get you on the schedule as soon as possible. If your system has failed entirely, we can refer you to a local HVAC repair specialist while we handle the sealing afterward.
Our pricing is consistent across our service area. A whole-home seal in Reno costs the same $800 – $2,400 range it would in Dallas or Fort Worth for comparable ductwork. Rural location does not trigger a travel surcharge. The main cost driver is the condition and accessibility of your specific duct system, not your ZIP code.
Every duct sealing job is covered by our 365-Day Done Right Promise in writing. If the seal fails within one year, Hollis returns and makes it right at no charge, including a free second visit. This applies to Reno exactly as it applies to every market we serve. The guarantee is not a verbal assurance. It is printed on your invoice.
