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 Missouri City
Air duct cleaning in Missouri City typically runs $350 – $650 for a full residential system and $800 – $2,500 for commercial buildings, with most jobs completed in a single visit. We’re the Air Duct Cleaning team at Hollis, and we’ve been working in the Missouri City market since 2004 as part of the Garrison Partners family. Our dispatch is coordinated from our Houston office, but our crews live and work in this area. They know the difference between a 1980s home near FM 1092 with original galvanized duct and a 2015 build in Sienna with R-8 flex in a 140°F attic. That local knowledge changes what we bring to the job and how we price it. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Missouri City’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Missouri City on one thing: doing what we said we’d do, at the price we wrote down, with technicians who arrive uniformed and background-checked. The Garrison Standard requires arriving inside the quoted window, pricing in writing before any work starts, completing the job by the book, and leaving the site clean. No exceptions.
Our 365-Day Done Right Promise covers 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. It’s a specific, written obligation.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday for someone to pick up.
Our technicians carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration products from Honeywell and Aprilaire. This is the same gear commercial crews use, not hardware-store attachments on a shop vac.
Residential Air Duct Cleaning in Missouri City
Residential Air Duct Cleaning in Missouri City means source removal from the full supply and return duct network, including the air handler, blower motor, and registers, using negative-air machines with HEPA filtration and rotary brush agitation. Because Missouri City sits on the Gulf Coastal Plain with some of the highest indoor humidity levels in the Houston metro, we see mold and biological growth in ductwork year-round, not just in summer. A typical residential job in Missouri City runs $350 – $650 for a full system cleaning, depending on the home’s size, duct material, and contamination level.
Supply and Return Duct Cleaning
We clean both sides of the system. The supply ducts push conditioned air into your rooms; the return ducts pull it back. In Missouri City’s older homes near the city core, we often find heavy debris accumulation in galvanized return trunks. In newer Sienna and Riverstone builds, the returns are more likely to show microbial staining from condensation. We address each with the right agitation method and verify with a camera inspection.
Video Inspection Before and After
We run a camera through the ductwork before we quote and after we finish. You see what we see. No guesswork, no “trust us” language. In Missouri City’s humid climate, this matters because what looks like dust on a register is often mold growth on the duct liner, and the difference changes how we treat it.
Commercial Air Duct Cleaning in Missouri City
Commercial Air Duct Cleaning in Missouri City covers office buildings, retail spaces, medical clinics, and multi-tenant properties, with typical jobs running $800 – $2,500 depending on system size and accessibility. Missouri City’s commercial growth along Highway 6 and FM 1092 has brought a mix of 1980s-era strip centers and newer medical office buildings, each with different duct configurations and code requirements. We work around business hours, coordinate with property managers, and provide documentation for insurance and compliance.
Systematic Cleaning for Occupied Buildings
We section off work areas, maintain negative pressure throughout the cleaning, and use HEPA-filtered containment so your tenants or employees aren’t breathing dislodged debris. Our technicians follow The Garrison Code on every commercial job: arrive inside the window, price in writing, complete the job by the book, leave the site clean.
Post-Cleaning Documentation
We provide before-and-after photos, a written summary of work performed, and any recommendations for filtration upgrades or duct sealing. Many Missouri City commercial clients use this documentation for insurance renewals or lease compliance.
Trusted Brands We Service in Missouri City
We service and install filtration and cleaning equipment from Honeywell, Aprilaire, and Abatement Technologies. These aren’t names we drop for credibility; they’re the actual brands we stock parts for, which means faster turnaround when a Missouri City customer needs a filter upgrade or a UV light installation after a cleaning. We also use Nikro negative-air machines and Rotobrush rotary brush systems on every job. When we recommend a MERV rating or a filtration upgrade, we’re specifying real products we can source and install, not theoretical solutions.
Common Air Duct Cleaning Problems We See in Missouri City Homes
- Mold in flex duct from attic condensation. In Sienna and Riverstone, R-8 flex duct runs through attics that hit 140°F in July. The temperature differential against humid indoor air causes condensation inside the duct liner. Homeowners wipe registers and think it’s dust. A camera inspection usually shows dark microbial growth on the flex interior.
- Heavy debris in original galvanized duct. Homes built in the 1970s and 1980s near Missouri City’s core often still have original or first-replacement galvanized steel duct. These systems accumulate decades of debris, and the seams leak enough to pull in attic air, compounding the contamination.
- Recontamination from a dirty air handler. We see this after competitors clean ducts but skip the blower motor and evaporator coil. The Gulf Coast humidity grows biofilm on these components, which re-seeds the freshly cleaned ductwork within weeks. We clean the full system, not just the runs.
- Failed “sanitiser” fogging treatments. A Sienna homeowner called us because the family room return smelled musty every time the system cycled, and the registers were dusting over within a week of wiping them down. Our tech ran a camera inspection down the R-8 flex trunk in the attic, found the duct sagging between hangers with standing condensation and dark microbial growth on the liner, then set up negative pressure with HEPA filtration and used agitation tools for full source removal on the supply and return ducts before re-hanging the run to restore its slope. The smell was gone at the next AC cycle, and we left the homeowner with a MERV rating recommendation for the filter so the air handler wasn’t fighting a choked return.

FAQs About Air Duct Cleaning in Missouri City
The combination of expansive clay soils, extremely hot attics, and Missouri City’s position in the highest-humidity zone of the Houston metro creates condensation inside flex duct runs that other suburbs don’t match. In Sienna and Riverstone specifically, the master-planned homes built since 2000 use R-8 flex duct routed through unconditioned attics, and the temperature differential between 140°F attic air and 72°F conditioned air causes moisture to form on the duct interior. That moisture feeds mold growth continuously from May through September, and often year-round. Call (361) 326-5060 if you smell mustiness when your system cycles – a camera inspection will show whether it’s mold or dust.
No, not as a standalone treatment. Fogging kills surface mold but leaves the moisture source untouched. In Missouri City’s climate, that means the growth returns within a season because the sagging flex duct is still condensing, the attic is still 140°F, and the humidity is still pushing 70% indoors. We only recommend antimicrobial treatment after source removal (physical agitation and negative-air extraction) and only when we’ve fixed the mechanical issue causing the moisture. Otherwise you’re paying for a temporary smell change, not a solution. Call (361) 326-5060 and we’ll show you the difference on camera.
Missouri City’s expansive clay soils shift with moisture, which can crack slab foundations and stress duct connections at the plenum. The hurricane-belt location means occasional water intrusion into attics during tropical storms, which soaks insulation and duct insulation, creating mold conditions that normal AC use doesn’t dry out. We inspect for these issues during our camera evaluation and note any structural or moisture problems that duct cleaning alone won’t fix. Call (361) 326-5060 for an inspection that looks at the whole system, not just the visible registers.
Expect heavy debris accumulation, likely some corrosion at galvanized seams, and significant air leakage. Original ductwork from this era in Missouri City was typically galvanized steel with fiberglass liner, and it’s had 40+ years of Gulf Coast humidity cycling through it. We can clean it thoroughly with rotary brush agitation and negative-air extraction, but we’ll also tell you honestly if the seams are too far gone or if the liner is deteriorating. Sometimes cleaning reveals that replacement is the better investment. We price both options in writing before any work starts. Call (361) 326-5060 for a camera inspection and honest assessment.
Partially, but not enough. The air handler and blower motor are where biofilm grows in Missouri City’s humidity, and that biofilm re-seeds clean ductwork within weeks. We clean the full system – ducts, air handler, blower motor, and evaporator coil – as one job. If a competitor quoted you duct-only, they’re leaving the source of recontamination in place. Our full-system cleaning includes all components, verified with before-and-after photos, covered by the 365-Day Done Right Promise. Call (361) 326-5060 for a quote that covers everything that needs cleaning.
