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 Angleton
Air duct cleaning in Angleton typically runs $350 – $650 for a complete residential system, with most jobs scheduled within a few business days and finished in three to five hours. We’re the Air Duct Cleaning crew that serves Angleton from our Dallas-Fort Worth dispatch office, with technicians who know the difference between a pier-and-beam crawlspace job off Mulberry Street and a slab-on-grade subdivision near the bypass. Call (361) 326-5060 for a written estimate before any work starts.
Angleton’s Gulf Coast humidity and its position in Brazoria County’s Industrial Corridor create a duct environment you won’t find fifty miles inland. We’ve cleaned systems in ranch homes near downtown where the crawlspace stays wet enough to grow mildew year-round, and in newer builds off Highway 35 where the AC runs ten months straight. Roy Castellanos and our team don’t guess at what’s in your ducts. We inspect first, price in writing, then clean with equipment that captures what it removes instead of blowing it back into your rooms.
Why Hollis Air Duct Cleaning Is Angleton’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Angleton is built on showing up inside the window we promised and leaving the price where we wrote it. No Angleton homeowner has ever watched our invoice climb after the van arrived. That’s The Garrison Standard, and it’s how we operate every job from the older neighborhoods near the Brazoria County Courthouse to the subdivisions stretching toward Lake Jackson.
Our technicians are background-checked and uniformed, and you’ll know who’s coming before they knock. Phones are answered by a live person 24 hours a day, seven days a week. Not a voicemail loop. Not a callback queue Monday morning. A real person who can schedule your Angleton appointment or answer what our process covers.
The 365-Day Done Right Promise backs every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. That’s not a satisfaction guarantee. That’s a specific commitment with a specific remedy, and we put it on paper before the first register comes off.
Vent Cleaning in Angleton
Vent Cleaning in Angleton means removing the visible grille, the boot behind the wall, and the first several feet of duct run that catches the most dust, pet hair, and cooking grease. In Angleton homes, we also find a film of fine particulate from the Industrial Corridor that settles in supply vents facing prevailing winds. A typical vent cleaning as part of a full system job runs $75 – $125 per vent when done properly with agitation and extraction, not just a vacuum hose waved at the opening.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In Angleton, these collect the humid, particulate-laden air that seeps through window seals and door gaps, especially in older homes near downtown where weatherstripping has seen better decades. We remove each grille, clean the boot, and agitate the duct run to dislodge buildup that a surface wipe misses.
Return Vent Cleaning
Return vents pull air back to the handler, so they’re your duct system’s intake. They run dirtiest because they never stop drawing. In Angleton’s climate, return boots often show the first signs of mold staining from the constant moisture load. We inspect with a borescope before cleaning, so you see what we see.
Air Duct Repair in Angleton
Air Duct Repair in Angleton addresses the damage that humidity, age, and poor initial installation inflict on duct systems in this market. Separated seams, collapsed flex runs, and corroded metal connections are common in pier-and-beam homes where crawlspace moisture attacks ductwork from the outside while the system runs from the inside. Typical repairs range from $200 – $450 for seam sealing and minor patching to $800 – $1,400 for section replacement or full trunk line rebuilds in accessible crawlspaces.
Duct Sealing and Mastic Application
Leaky ducts pull crawlspace air into your supply stream. In Angleton, that means musty, mold-laden air straight into your bedroom. We seal with mastic, a brush-applied compound that flexes with temperature changes, unlike tape that dries and fails. Sealing alone can improve system efficiency 15 – 20 percent in a typical Angleton home with aging metal ductwork.
Insulation Replacement
Uninsulated or water-damaged duct wrap in a damp Angleton crawlspace is a mold factory. We replace saturated insulation with new vapor-barrier-wrapped product and address the condensation source, not just the symptom. A fogger can’t fix wet duct wrap. Only removing the moisture source and replacing the damaged material does.
Trusted Brands We Service in Angleton
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation inside duct runs, Nikro negative-air machines that maintain suction while we work, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t show up with a shop vac and a brush. The Rotobrush system loosens adhered debris from duct walls while the Nikro unit captures it under HEPA filtration, so nothing recirculates through your Angleton home. Guardsman filtration products finish the job at the register level, giving you a complete system from mechanical cleaning to final air polish. We stock common parts and filtration media locally, so Angleton customers aren’t waiting on shipping for replacements or upgrades.
Common Air Duct Cleaning Problems We See in Angleton Homes
- Chronic mold in pier-and-beam crawlspaces. Angleton’s average summer humidity above 75 percent keeps metal duct runs sweating in crawlspaces that never dry out. We find visible mildew on duct wrap in homes off Chenango and Mulberry where the ground stays damp year-round.
- Industrial particulate infiltration from the Blue Ridge Road corridor. Fine fallout from Brazoria County’s petrochemical facilities enters homes through gaps in window and door seals, accumulating in return ducts and on blower wheels. Generic cleaners miss this entirely because it looks like household dust until tested.
- “Blow and go” recontamination. Some outfits blow compressed air through ducts without containment, pushing mold spores and refinery particulate past registers into living spaces. We capture debris under negative pressure with HEPA filtration, period.
- Fogging upsells that leave biofilm intact. A chemical mist doesn’t remove mold colonies. It wets them. In Angleton’s humidity, wet biofilm regrows within weeks, and the homeowner paid for a temporary smell cover, not a fix.
Pricing for Air Duct Cleaning in Angleton, TX
A typical residential full-system cleaning in Angleton runs $350 – $650 for a single-system home up to about 2,500 square feet. Larger homes or systems with extensive contamination, separated duct runs, or accessibility issues in tight crawlspaces may reach $800 – $1,200. Commercial duct cleaning in Angleton’s retail and light industrial spaces starts around $800 and scales with system complexity and access.
What moves the price: number of supply and return vents, whether the system includes a main trunk line or just flex runs, crawlspace accessibility in pier-and-beam construction, and whether we find damage requiring repair before cleaning is worthwhile. We inspect first, then write the price. It does not move at the door. One flat price per system, agreed before work starts. No per-vent add-ons, no “we found a surprise” surcharges.
We provide before-and-after photos of your own ducts, not stock images. You’ll see what came out, what the interior looks like now, and whether any damage needs addressing. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Angleton
The smell comes from mold and mildew growing on duct surfaces in your crawlspace or plenum, activated when airflow disturbs the colony. In Angleton’s humid climate, especially in pier-and-beam homes with uninsulated metal runs, ducts stay wet enough to support biological growth year-round. The odor is your warning that the system is circulating more than air. Call (361) 326-5060 and we’ll inspect with a borescope to show you the source.
Yes. Pier-and-beam construction puts ductwork in a crawlspace exposed to ground moisture and outdoor humidity, while slab homes bury ducts in concrete or run them through conditioned attic space. Angleton’s pier-and-beam homes often have uninsulated metal trunk lines that sweat puddles underneath, a problem slab subdivisions simply don’t face. We adjust our approach: inspecting crawlspace conditions, checking insulation integrity, and sealing condensation sources before cleaning the interior.
It can. Fine particulate from refinery and chemical operations travels on prevailing winds and enters homes through normal infiltration. In Angleton homes closest to the Industrial Corridor, we find a distinctive fine gray film in return ducts and on blower wheels that differs from typical household dust. Standard cleaning removes it; specialized HEPA filtration during cleaning prevents redistribution. We assess this during inspection and note whether your system shows elevated industrial particulate loading.
No, not as a standalone fix and not in Angleton’s humidity. Fogging mists chemical into ducts without removing the biofilm where mold colonies anchor. In a damp crawlspace environment, wet biofilm regrows within weeks. We address biological contamination with mechanical agitation, negative-air extraction, and moisture-source remediation. If a contractor’s primary solution is a fogger, they’re treating the smell, not the problem. Save your money.
Every three to five years for most Angleton homes, sooner if you notice musty odors, visible mold, or reduced airflow. Homes in the dampest pier-and-beam sections, especially near downtown Angleton where drainage is older, may need inspection every two years. The humidity here doesn’t let ducts dry out between cycles, so biological growth progresses faster than in drier climates. Call (361) 326-5060 and we’ll recommend an interval based on your home’s construction and condition.
