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 Air Duct Cleaning Across South Houston
Air duct cleaning in South Houston typically runs $300 – $650 for a full residential system, with most jobs completed in a single visit. Our crews serve South Houston from our Houston office, carrying Rotobrush rotary systems and Nikro negative-air machines built for the specific contamination this area throws at ductwork. Call (361) 326-5060 for a written estimate before any work starts.
We’ve been cleaning ducts in South Houston since 2004, and we know the difference between a home near the ship channel and a ranch off Almeda-Genoa Road. The dust isn’t the same. The problems aren’t the same. The fix shouldn’t be either. That’s why our Air Duct Cleaning team shows up with equipment matched to what we actually find, not a one-size-fits-all vacuum and a prayer.
Why Hollis Air Duct Cleaning Is South Houston’s Preferred Air Duct Cleaning Company
We’re part of the Garrison Partners family, and every Hollis location runs on The Garrison Standard: written price before work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise backed in writing. In South Houston, that means something specific. We’ve cleaned ducts in the post-war ranches near Spencer Highway, the townhomes going up near Pearland’s edge, and the rural properties where gravel roads throw pale, gritty dust into systems that run hard year-round.
Our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you schedule in South Houston, we arrive inside the quoted window, price the job in writing before touching anything, and leave the site clean. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s the 365-Day Done Right Promise, and it’s on every job.
Roy Castellanos leads our operation with the same discipline we bring to your ductwork: show up, price it straight, do it by the book. South Houston homeowners have enough to worry about without wondering if the crew will actually arrive or if the invoice will match the quote.
Air Duct Inspection in South Houston
Air Duct Inspection in South Houston starts with a camera run through your supply and return lines to see what the humidity, industrial fallout, and road dust have actually deposited inside. Most South Houston homeowners need an inspection when they notice musty airflow, uneven cooling, or a spike in energy bills after a humid summer. A full video inspection here runs $150 – $250, and we apply that toward your cleaning if you move forward.
What We Look For in Older Systems
The 1950s-70s ranch homes that dominate South Houston’s housing stock often have rigid metal ducts that have separated at seams or rusted through from decades of condensation. Our camera finds the gaps where attic air gets pulled in, the rust flakes collecting in low spots, and the mold colonies that take hold where humidity pools. We mark every problem with footage you can see for yourself.
Outbuilding and Shop Systems
On rural South Houston properties, we inspect the main house ducts and any detached shop or outbuilding air handlers in the same visit. The dust load from unpaved roads and wood heat hits these systems harder and faster than most homeowners realize. A MERV 8 filter on a shop building is often overwhelmed within weeks.
Residential Air Duct Cleaning in South Houston
Residential Air Duct Cleaning in South Houston means source removal: we put the system under negative pressure with a Nikro machine, agitate the duct walls with a Rotobrush rotary system, and capture everything in HEPA filtration before it enters your living space. A typical full-system cleaning for a South Houston home runs $300 – $650, depending on system size, accessibility, and how long it’s been since the last cleaning. Homes with detached shops or outbuildings add $150 – $350 per additional system.
The Rural Difference
Drive time to rural South Houston properties off the beaten path means our techs often start a job at dawn and run two systems – main house plus detached shop or outbuilding – on one visit, because the dust load from unpaved roads and open land requires a full day of source removal. In the city itself, duct dust tends to be dark, sticky, and chemical-laden; on rural properties, it’s more like fine, pale, gritty road dust and pollen, which changes the cleaning approach, not just the amount.
Field Vignette
We pulled up to a 1960s ranch on a gravel stretch near Almeda-Genoa Road where the homeowner had a wood-burning stove in the shop building. The supply and return ducts on the main house were packed with a half-inch of pale, gritty dust and pollen, while the shop’s air handler blower motor was coated in fine sawdust-like debris that had bypassed a MERV 8 filter. After a camera inspection and negative pressure setup, we used agitation tools and HEPA filtration to do source removal on both systems, then degreased the shop’s blower motor and replaced the filter with a higher MERV rating to catch the road dust and wood ash.
Trusted Brands We Service in South Houston
We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for South Houston customers who need better particle capture between cleanings. For homes near the ship channel dealing with that oily, chemical-laden dust, we keep heavy-duty degreasers and antimicrobial treatments on every truck. For rural properties battling road dust and pollen, we stock higher-MERV filters and can source HEPA upgrades for most residential systems. Most filter replacements and small parts happen same visit. No waiting on a warehouse order while your system runs dirty.
Common Air Duct Cleaning Problems We See in South Houston Homes
- Industrial fallout buildup near refineries. The petrochemical haze along the ship channel deposits dark, sticky dust with a faint chemical odor that standard vacuums can’t remove. We use degreasing agents and rotary agitation to break it loose before negative-air extraction.
- Mold in humid attic ducts. South Houston’s year-round humidity means condensation inside metal ductwork, especially in poorly insulated attics. We find black or green mold colonies during camera inspection and treat with antimicrobial agents after source removal.
- Leaky rigid metal ducts in post-war ranches. Those 1950s-70s systems have separated seams and rust holes that pull in hot attic air, loading the system with fiberglass and dust. Sealing with mastic after cleaning fixes the root problem.
- Outbuilding systems overloaded with road dust and wood ash. Rural properties around South Houston often skip shop duct cleaning, but unpaved roads and wood heat load those systems faster than the main house. The pale, gritty dust requires different agitation tools than the city’s oily residue.

FAQs About Air Duct Cleaning in South Houston
Every 2 – 3 years for the main house, and every 1 – 2 years for detached shop or outbuilding systems. The pale, gritty road dust and wood ash load filters and ducts faster than standard suburban dust, and MERV 8 filters often fail within weeks on shop buildings. Call (361) 326-5060 and we’ll inspect both systems to set a schedule based on your actual dust load.
Yes. We schedule rural South Houston properties for a full day and run both systems in one trip. The drive time to outlying areas means it doesn’t make sense to make two trips, and the dust load from unpaved roads usually means both systems need attention. One flat price per system, written before we start.
The dust itself. Inside South Houston near the refineries, we find dark, sticky, chemically laden residue that needs degreasing. On rural properties, it’s fine, pale, gritty road dust and pollen that responds better to aggressive agitation and HEPA capture. The equipment changes, the approach changes, and the cleaning interval changes. We don’t use the same protocol for both.
Yes. We inspect, clean, and degrease blower motors and air handlers in detached shops and outbuildings, and we replace filters with higher-MERV options rated for your dust load. The blower motor on a shop system often gets coated in fine debris that bypasses standard filters, which strains the motor and recirculates dirty air. We treat it as part of the system, not an afterthought.
Yes. High humidity means condensation inside ductwork, which binds road dust to duct walls and creates ideal conditions for mold. Even with good filtration, the combination of gritty dust and moisture means South Houston ducts need more frequent attention than drier climates. We recommend checking your system every two years and cleaning when we find buildup exceeding a quarter-inch.
