Fast, Reliable Air Duct Cleaning Across Preston Hollow
Preston Hollow homes need a duct cleaning company that understands what’s actually inside those long, original duct runs. We’re talking about estates built between the 1950s and 1980s, many with multiple HVAC zones, original sheet metal, and decades of accumulated dust from Dallas’s mature oak and pecan canopy. Our crews know these systems because we work on them every week. We show up uniformed, we write the price down before any work starts, and we stand behind it for a full year. If you need air duct cleaning in Preston Hollow, call (361) 309-6223 for a straight answer and a written estimate.
Why Hollis Air Duct Dallas Is Preston Hollow’s Preferred Air Duct Cleaning Company
We operate under the Garrison Standard, and that means one thing in Preston Hollow: written prices, written guarantees, and a 365-Day Done Right Promise that says if the work fails within a year, we come back and make it right at no charge. The price you see is the price you pay. It does not move at the door.
Our crews are background-checked and uniformed. You know who’s walking into your home before they arrive. And when you call, a live person answers. No voicemail loops, no callback queues. That matters when you’re coordinating access to a 1970s estate on Strait Lane or a custom ranch off Royal Lane.
We also carry professional-grade equipment from Rotobrush, Nikro, Honeywell, and Aprilaire. These are the same tools commercial crews use for hospitals and office towers, not hardware-store attachments. For Preston Hollow’s long original metal trunk lines, that equipment difference is the difference between a surface dusting and source removal. Roy Castellanos leads our team, and he holds every job to the Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean.
Styles & brands we work with
Vent Cleaning in Preston Hollow
Vent cleaning in Preston Hollow is rarely just about the registers you can see. In older estates with sprawling attic spaces, the visible supply vents often look fine while the real problem sits twenty feet into the trunk line. We remove the register covers, camera-inspect the branches, and run a rotary brush system through the full supply and return paths. Then we pull negative air with a Nikro machine and HEPA filtration so the dust we loosen does not recirculate through the home. For a typical Preston Hollow home with two systems and roughly 15 to 20 vents, expect to pay between $450 and $750 for a full vent and branch cleaning.
Supply Vent and Branch Cleaning
Supply branches on Preston Hollow’s original systems were often never cleaned when a new furnace or condenser was installed. We clean each branch back to the trunk, including the boots at the register. That is where oak pollen and fine renovation dust settle over decades.
Register and Grille Restoration
Preston Hollow homes with original register covers often have years of paint overspray and caked dust on the grille fins. We hand-clean or refinish them so the airflow and appearance both improve. It is a small detail that tells you the job was done completely.
Air Duct Repair in Preston Hollow
Air duct repair in Preston Hollow usually means fixing something that has been wrong for a long time. On older custom estates, we regularly find collapsed return flex in the attic, disconnected branch runs, or rusted sections of original metal trunk. These defects do more than waste air. They let conditioned air dump into the attic or pull hot soffit air into the system. A typical duct repair on a Preston Hollow home runs $300 to $900, depending on how many runs need rebuilding or duct sealing. The price is written before work begins.
Return Air Drop Rebuilding
Original returns in Preston Hollow are frequently undersized for modern high-efficiency systems. When the return is starved, the system goes into negative pressure and pulls dust from attic insulation and crawlspace soil into the air stream. We rebuild the return drop, enlarge the plenum opening where needed, and seal every seam with mastic.
Plenum and Trunk Sealing
Older sheet metal trunks leak at the seams, especially after decades of thermal expansion and remodels. We seal accessible seams with duct mastic, not tape. Mastic hardens into a permanent bond. It stops the air leaks that keep rooms uneven and push utility bills higher every summer.
Trusted Brands We Service in Preston Hollow
Hollis Air Duct Dallas works on every major brand found in Preston Hollow homes, including Trane, Carrier, Lennox, and Rheem. Because these estates often run two or three systems from different eras, we keep common duct fittings, flex sections, and mastic on our trucks so most repairs happen same-visit. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, paired with filtration products from Honeywell and Aprilaire. When a Preston Hollow customer asks what we recommend for ongoing filtration after a cleaning, we explain the Aprilaire media cabinets and Honeywell electronic air cleaners in plain terms, with written pricing.

AfterCommon Air Duct Cleaning Problems We See in Preston Hollow Homes
- Collapsed or disconnected return runs hidden deep in attic spaces. In sprawling ranch attics, a crushed 8-inch flex can sit unnoticed for years, starving the system and pulling dust from soffit vents into the conditioned air.
- Original oversized metal trunk lines holding decades of construction debris. Repeated remodels leave drywall dust, sawdust, and old insulation inside long trunk runs. A standard cleaning that only hits branches and registers misses this entirely.
- Undersized return plenums on systems upgraded to high-efficiency units. Newer blowers pull more air than the old return can supply. The result is negative pressure, dust infiltration, and rooms that never hold temperature.
- Mature tree canopy loading the system with fine pollen and organic matter. Preston Hollow’s oaks and pecans produce a heavy pollen season. With systems running nearly year-round due to Dallas humidity, that pollen recirculates constantly unless removed at the source.
Pricing for Air Duct Cleaning in Preston Hollow, TX
For a full system cleaning in Preston Hollow, expect to pay $450 to $900 depending on the number of systems and the total vent count. A one-system home with a single return typically lands near $450. A two-system estate with long original metal trunks, multiple returns, and video inspection runs closer to $800 or $900. Duct repairs run $300 to $900, and sealing work typically adds $150 to $400 depending on accessible seam footage. We write every price before the work starts. The number does not move.

On a 1963 custom ranch on Walnut Hill Lane, we found a crushed 8-inch return flex in the attic that had reduced airflow to a 5-ton Trane system for years. The homeowner had already paid for two other cleanings that never fixed the dust or the uneven temperatures. We ran a camera inspection, confirmed the collapse and a disconnected branch, rebuilt the return drop, sealed the plenum, and performed source removal with HEPA filtration. Static pressure dropped 0.3 inches, and the master suite finally held temperature. That is what we mean when we say cleaning alone is not enough in Preston Hollow.

FAQs About Air Duct Cleaning in Preston Hollow
Most standard cleanings only address registers and accessible supply branches. In pre-1980 Preston Hollow homes, original metal trunk lines and long return runs hold decades of debris that a branch-only cleaning never reaches. Add undersized returns pulling attic dust into the system, and the dust returns within weeks. A full system cleaning with camera verification is the fix. Call (361) 309-6223 to schedule an inspection.
After. Demolition and drywall work load the ducts with fine dust that settles deep in trunk lines. Clean after the remodel is complete and the site is dust-free, then replace the filters. Scheduling this after the work wraps prevents paying twice. Call us the week before the remodel ends and we will lock in a date and a written price.
Collapsed or disconnected return flex in attic spaces, usually on original runs from the 1960s and 1970s. The return side is out of sight, so it fails silently for years. We camera-inspect every return path during a cleaning and show you the footage before and after. If a return is crushed, we rebuild it same-visit. Call (361) 309-6223 for a written quote.
They add a heavy pollen load, but the bigger factor is that Dallas humidity keeps HVAC systems running nearly year-round. That means pollen, dust, and organic debris circulate constantly. Homes with mature canopies and original ducts benefit from a full source-removal cleaning every three to five years, more often if anyone in the home has allergies. We can walk you through what your system actually needs.
Yes, if the ducts are intact we clean them with a rotary brush and negative-air extraction at the right static pressure for the duct material. We inspect for rust-through or separated seams first. If a section is beyond cleaning, we replace only that section and document it with photos. The price for any replacement is written and agreed before we cut metal.
