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 Houston
Air duct cleaning in Houston typically runs $350 – $650 for a full residential system, with post-storm moisture assessments starting around $200 and full flood-damaged replacements reaching $1,800 – $3,200 depending on attic access and duct material. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our Houston office coordinates crews across the metro from Galena Park down to Pasadena. If your ducts need attention, call us at (361) 326-5060 for a written estimate before any work starts.
Houston’s not like other Texas markets. The humidity here is its own character, and after a tropical storm or hurricane flood, the question isn’t whether your ducts are dirty – it’s whether water got inside them. That’s a different job entirely, and it’s where a lot of crews get it wrong. We document everything in writing, price it before we touch it, and stand behind it for 365 days.
Why Hollis Air Duct Cleaning Is Houston’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004, and our Houston operation runs on The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean. No exceptions. Our technicians are background-checked and uniformed, and when you call (361) 326-5060, a live person answers – no voicemail loops, no callback queues.
Houston homeowners know the difference between a crew that shows up and one that doesn’t. We’ve built our reputation in neighborhoods like Meyerland, the Heights, and Clear Lake by doing what we said we’d do, at the price we said we’d do it. The 365-Day Done Right Promise covers every job: if the work fails within a year, we return and make it right at no charge, including a free second visit.
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies – the same tools commercial crews use, maintained to the same standard. We don’t rent gear from the hardware store.
Dispatch and scheduling are coordinated from our Houston office, so when you book a window, we’re routing from inside the metro, not driving in from Austin or Dallas. That matters when you’re dealing with post-storm moisture and mold doesn’t wait.
Vent Cleaning in Houston
Vent cleaning in Houston means more than brushing out the register covers you can see from the hallway. Our crews use Rotobrush rotary brush systems and Nikro negative-air machines to pull debris from the full duct run – from the supply plenum in your attic down to every register in your living space. A typical residential vent cleaning in Houston runs $150 – $280 per system, with whole-house packages starting around $350.
Because Houston AC systems run 9 – 10 months a year and the mild winters never dry the system out, duct interiors stay damp and biologically active year-round. That means vent cleaning here often includes mold assessment, not just dust removal. We check for condensation staining, musty odors, and visible growth before we quote the scope.
Supply Vent Focus
Supply vents push conditioned air into your rooms. When they’re clogged with Houston’s combination of pollen, construction dust, and biological growth, airflow drops and your system works harder for less comfort. We clean the full run, not just the visible grille.
Return Vent Deep Clean
Return vents pull air back to the handler, so they’re the first collection point for pet dander, skin cells, and cooking particulates. In Houston’s older slab-on-grade homes, these runs often sit low in walls where humidity concentrates. We inspect with a camera before we quote.
Air Duct Repair in Houston
Air Duct Repair in Houston is rarely about a single disconnected joint. In this market, it’s usually about flexible duct runs in the attic that have baked, sagged, or pulled apart at the collar. Typical repairs run $200 – $450 for localized fixes, with full attic re-ducting on a two-story home reaching $1,200 – $2,400 depending on linear footage and access difficulty.
The real problem is often hidden. After a tropical storm pushes water into a slab-on-grade home in Meyerland, our crew ran a camera inspection through the supply and return ducts and found standing water pooled in the flexible runs and around the air handler in the attic. We cut out the saturated flex, dried and treated the intact trunk lines, replaced the wet air handler insulation, and rebuilt those runs with new flex sealed at every register. We documented each wet section with tagged photos and moisture readings so the homeowner’s insurer could see exactly what was replaced versus source-removed.
Attic Flex Replacement
Most Houston homes built from the 1970s through the 2000s use flexible duct runs in the attic. That attic bakes to 140°F in August and sweats condensation in shoulder seasons. Flex duct degrades faster here than in drier climates. We replace with properly sized, insulated flex and seal every connection with mastic, not tape.
Post-Storm Moisture Remediation
After flooding, the first question isn’t “is the duct dirty” but “did water get into the ducts.” We test supply and return lines separately, document saturation with moisture meters and photos, and give you a written scope that distinguishes clean-and-dry from full replacement. Insurers need that documentation. We provide it.
Trusted Brands We Service in Houston
We maintain equipment from Nikro, Honeywell, and Aprilaire, and we stock common filtration and sealing components for Houston’s most prevalent system types. That means faster turnaround on repairs and replacements – no waiting two weeks for a specialty part to ship from out of state. Our Nikro negative-air machines run HEPA filtration during cleaning, which matters in occupied homes where we can’t shut down the living space. Honeywell and Aprilaire media filters are what we spec when a Houston homeowner needs better particle capture after remediation work. We don’t guess at compatibility. We match the component to the system, document it in the work order, and guarantee it for 365 days.
Common Air Duct Cleaning Problems We See in Houston Homes
- Year-round biological growth in attic flex runs. Houston’s subtropical Gulf humidity plus summer dew points in the mid-70s means condensation forms inside ductwork whenever the AC cycles off. The mild winters don’t reset the system, so mold and biological growth stay active through the year. Cleaning without addressing the moisture source is temporary.
- Flood-saturated ductwork after tropical storms. After a hurricane or tropical storm flood, the first question locals ask isn’t “is the duct dirty” but “did water get into the ducts.” Quick post-storm duct inspection is a Houston-specific service call you don’t get in Dallas. We determine whether supply or return lines were breached, since that dictates clean-and-dry versus full replacement.
- Insurer denies claims because crews cleaned instead of documenting. A generic dust-only clean skips the supply-and-return water test, so hidden saturation under attic insulation is missed and later reads as a pre-existing condition to the carrier. We photograph and moisture-map before we touch anything.
- Moisture lingers after inadequate drying. Even after visible water recedes, humidity remains in attic flex runs and air handlers. A “dry” duct re-wets and mold returns within weeks because the source – standing water, gaps, or failed insulation – was never corrected. We don’t close the job until moisture readings confirm the system is actually dry.

FAQs About Air Duct Cleaning in Houston
If water crossed into the supply or return ducts and reached the air handler, replacement is usually required – cleaning saturated flex duct leaves mold-stained material that insurers won’t cover later and that re-contaminates within weeks. We run camera inspections and moisture readings through every line, document saturation with tagged photos, and give you a written scope that distinguishes clean-and-dry from full replacement so your adjuster can approve it. Call (361) 326-5060 to schedule an assessment.
Yes – Houston’s AC systems run 9 – 10 months a year and stay wet, so duct interiors become a year-round mold incubator that’s a different problem than in dry climates. We recommend inspection every 2 – 3 years in this market, versus 4 – 5 years in drier regions, and sooner after any water intrusion event. Call (361) 326-5060 to check your schedule.
Most Houston homes are slab-on-grade ranch and two-story builds from the 1970s – 2000s with flexible duct runs in the attic – a hot, humid space that bakes and sweats all year. The living space registers are just the visible end; the actual failure point is almost always upstream in that attic flex. We inspect the full run with cameras, not just the grilles you can see. Call (361) 326-5060 for a full-system inspection.
Yes – our Nikro negative-air machines create suction at the collection point so debris doesn’t escape into your living space, and HEPA filtration captures particles down to 0.3 microns. The system runs while you’re home, though we do ask that pets and sensitive individuals stay out of the immediate work zone. Call (361) 326-5060 to discuss scheduling around your household.
We provide moisture meter readings with timestamps, tagged photos of every saturated section, a written scope distinguishing replacement from clean-and-dry, and itemized invoicing that matches insurance standard formats. This documentation package is what prevents the common denial: “crew cleaned flooded flex instead of replacing it.” We build it on-site, not after the fact. Call (361) 326-5060 and we’ll explain exactly what your carrier will need.
