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.

Balch Springs sits in a tough spot for duct longevity. The suburb catches construction dust rolling off the I-20/LBJ corridor and sits downwind of Metroplex ozone and particulate plumes. That means the dust loading here is heavier than in calmer pockets of Dallas County. In older homes near Balch Springs Road, we’ve found the real problem is often not dirty ducts but leaky ones, original galvanized trunk lines patched with dried-out tape, and plenum connections that have never been sealed at all. Our Duct Sealing team treats the cause, not just the symptom.
Why Hollis Air Duct Cleaning Is Balch Springs’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our crews have worked enough Balch Springs homes to know what to expect before we walk through the door. The 1960s slab homes around old downtown, the pier-and-beam ranches off Balch Springs Road, the 1990s tracts on the east side, and the newer infill along I-20 each present different duct problems. That local pattern recognition saves time and keeps our pricing honest.
Every job gets a written price before we touch anything, backed by our 365-Day Done Right Promise. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Duct Insulation in Balch Springs
Duct Insulation in Balch Springs addresses a problem most homeowners don’t notice until their summer electric bills spike or the back bedroom never cools down. In this market, uninsulated or poorly insulated flex duct in unconditioned attics bleeds cooled air for six months straight, from April through October. The typical Balch Springs home needs R-6 to R-8 insulation on flex runs, with particular attention to the plenum and trunk connections where metal meets flexible material. Expect $600 – $1,400 for full duct insulation depending on linear footage and attic accessibility.
When Attic Heat Kills Your Efficiency
Attic temperatures in Balch Springs regularly hit 140°F in July and August. Uninsulated supply ducts running through that space are trying to push 55°F air through a 140°F tunnel. The result is lukewarm air at the register, longer run times, and compressor wear. We wrap existing accessible duct with formaldehyde-free fiberglass insulation, seal every seam with mastic, and verify temperature drop at the farthest register before we leave.
Older Flex Duct That’s Lost Its Wrap
The early flex duct installed in 1980s and 1990s Balch Springs subdivisions had thinner insulation that compresses and tears over decades. We’ve pulled down runs in east-side tracts where the insulation jacket has disintegrated entirely, leaving bare plastic duct exposed to attic heat. Replacement with properly insulated new flex, sealed at every collar, fixes the thermal loss and the air leakage in one pass.
HVAC Duct Sealing in Balch Springs
HVAC Duct Sealing in Balch Springs is the repair that stops conditioned air from escaping into your attic, crawlspace, or wall cavities. In our market, a typical home loses 20 – 30% of heated and cooled air through leaks at plenum connections, branch collars, and failed tape joints. For Balch Springs homeowners, that waste is compounded by near-continuous system runtime, April through October for cooling and intermittent heating December through February. Whole-house duct sealing with mastic and fiberglass mesh runs $450 – $1,200; partial sealing of a specific problem zone starts around $300.
Leak Detection Before the Seal
We pressure-test the duct system and use a smoke pencil or theatrical fog to pinpoint leaks. In Balch Springs homes with original galvanized trunk, the leaks cluster at the collar connections and at the plenum where the air handler meets the main trunk. We mark every leak, show the homeowner the footage, then seal with water-based mastic rated for duct applications, not hardware-store tape that will dry out in two seasons.
The Plenum Problem
Most “duct sealing” complaints we hear about start with an unsealed plenum. The plenum is the large metal box that connects your air handler to the trunk lines. If it’s not sealed at the seams and at the air handler connection, sealing the branch ducts downstream is cosmetic. We seal the plenum first, then work outward to the branches. This is standard on every job, not an upsell.
Trusted Brands We Service in Balch Springs
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for source removal, and filtration products from Honeywell and Guardsman. For Balch Springs homes with allergy concerns or post-construction dust loading, we stock Honeywell filter cabinets and MERV 11 replacement media locally, so there’s no waiting on shipped parts. The same gear we use in commercial jobs is what runs in your attic, and we explain what each piece does before we start it up.
Common Duct Sealing Problems We See in Balch Springs Homes
- Original galvanized trunk with dried tape patches. The 1960s – 1980s ranch homes near Balch Springs Road were built with galvanized steel trunk lines and early flex duct. Decades of HVAC contractors have patched leaks with cloth duct tape, which dries out, cracks, and fails. The tape has to come off, the metal has to be cleaned, and the joint has to be sealed with mastic and mesh to last.
- Unsealed plenum connections dumping air into unconditioned attics. In pier-and-beam and ranch homes throughout Balch Springs, the plenum sits in the attic or a closet chase with no seal at the air handler connection. Conditioned air escapes upward while attic dust gets pulled inward through the same gap. Sealing the plenum is the fix; skipping it is why other seals fail.
- No filter grille on central-hall returns in older slab homes. In the 1960s core near old downtown Balch Springs, return ducts were run through the central hallway with no filter grille at all. Pet hair, carpet fiber, and I-20 construction dust get pulled straight into the blower and distributed through every supply register. The real fix is a return-side filter grille and sealed plenum, not another cleaning.
- Post-construction drywall dust in newer I-20 infill. Homes built or renovated along the I-20 frontage in the last decade often have ducts loaded with drywall dust from construction. Sealing without source removal first traps that dust inside the system. We clean with negative pressure and HEPA filtration, then seal, so the problem stays solved.

FAQs About Duct Sealing in Balch Springs
Post-construction drywall dust from I-20 corridor builds loads the entire duct system with fine particulate that standard filters won’t catch. If your contractor didn’t run a negative-pressure clean before close-out, that dust keeps circulating. We remove it with source removal and HEPA filtration, then seal the system so new dust doesn’t get pulled in through leaks. Call (361) 326-5060 for an inspection and exact quote.
It was common construction practice in 1960s slab homes near old downtown Balch Springs, but it’s not acceptable for air quality or equipment longevity. Without a filter grille, everything from pet hair to construction dust enters the blower unfiltered, coats the evaporator coil, and gets distributed through every room. We install a return-side filter grille and sealed plenum as part of the repair. Call (361) 326-5060 to have your return configuration checked.
We pressurize the duct system and use smoke pencils or theatrical fog to make leaks visible. In Balch Springs homes, the leaks almost always cluster at plenum connections, branch collars, and failed tape joints on original galvanized trunk. We show you the footage before we seal anything. Call (361) 326-5060 to schedule a pressure test.
Yes, but only when paired with proper filtration. Sealing stops your system from pulling unfiltered attic and wall-cavity air into the ducts. In Balch Springs, where spring wind events load the return side with ragweed and mold spores, that matters. We typically pair sealing with a Honeywell filter cabinet at MERV 11 so the air that reaches your rooms is actually filtered. Call (361) 326-5060 to discuss the right combination for your home.
Clean first, always. Sealing a dirty system traps dust, mold spores, and construction debris inside the ducts. We use Nikro negative-air machines and Rotobrush mechanical agitation for source removal, then seal with mastic and mesh. The 365-Day Done Right Promise covers both the clean and the seal. Call (361) 326-5060 to schedule the full sequence.
