Fast, Reliable Air Duct Cleaning Across Alvin
Air duct cleaning in Alvin typically runs $450 – $900 for a full residential system, and the job usually takes 3 – 5 hours depending on home size and duct count. Our crews know the housing stock and the climate here, and we schedule directly for Alvin homeowners. If you need a written quote before anyone touches your system, call (713) 936-5800.
We work in Alvin every week. That matters because this city has a split housing profile: newer high-efficiency builds with flexible ducts sitting beside 1960s – 80s brick ranch homes whose original metal ductwork was never designed for nine months of AC runtime. The difference between cleaning those two systems correctly comes down to equipment and inspection, not a generic truck-mounted vacuum. Our technicians run Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines for true source removal, which means dust and microbial growth come out of the ducts instead of getting stirred back into your living room.
Your price is written down before work starts. It does not move at the door. Every job is covered by our 365-Day Done Right Promise: if it is not done right, we come back and make it right at no charge.
Why Hollis Air Duct Houston Is Alvin’s Preferred Air Duct Cleaning Company
We are not the cheapest bid in Alvin, and we do not try to be. Homeowners who call us have usually been burned before: a coupon price that tripled once the van pulled up, a crew that left attic insulation scattered across the hallway, or a cleaning that did nothing for the musty smell coming out of the vents. Our standard is different.
Every technician who arrives at an Alvin home is background-checked and uniformed. You know who is walking through your door before they get there. The price is in writing before any work starts, and the equipment is professional-grade, the same type commercial crews run on large buildings. We carry rotary brush systems from Rotobrush, negative-air collection from Nikro, and filtration products from Honeywell and Aprilaire. That is the difference between brushing dust loose and actually pulling it out of the duct under negative pressure with HEPA filtration.
Roy Castellanos leads our team, and the standard he enforces comes from The Garrison Standard, the operating code behind every Garrison Partners location. Arrive inside the quoted window. Price in writing. Do the job by the book. Leave the site clean. In Alvin, that standard gets tested, because the older subdivisions west of Highway 35 have duct systems that punish shortcuts.

Air Duct Repair in Alvin
Air Duct Repair in Alvin usually means one of three things: sealing separated return runs in older ranch homes, repairing crushed or disconnected flex duct in newer builds, or replacing sections of metal duct that have rusted through from years of humidity and condensation. This is the work that makes cleaning actually hold, because a duct system with leaks and gaps will re-contaminate itself within weeks no matter how thoroughly it was cleaned.
Sealing Retrofitted Supply Runs
Many Alvin homes built between 1965 and 1985 have had their AC systems replaced, sometimes twice. The new air handlers were fitted to original metal supply runs, and the joints where new meets old are often poorly sealed. We regularly find gaps pulling attic insulation and fine dust into the air stream. Repair means mechanical fastening plus mastic sealant at every accessible joint, then verifying the seal with a pressure test before we consider the job done.
Sectional Duct Replacement
When water intrusion has rusted a section of metal duct or soaked flex duct, cleaning is not enough. We cut out the damaged section and replace it with properly sized, insulated duct matched to the system’s static pressure requirements. A sectional replacement in Alvin typically runs $200 – $500 depending on access and length, and it is always priced in writing before we start. We document the damaged section with photos so you have a record for your insurer.
Ductwork Cleaning in Alvin
Ductwork Cleaning in Alvin is source removal, not surface brushing. The process involves connecting a Nikro negative-air machine to the duct system to put the entire network under vacuum, then mechanically agitating the interior walls with a Rotobrush rotary brush so debris, dust, and biological growth release and get pulled into HEPA filtration instead of escaping into your home. This is the method our Air Duct Cleaning team uses on every system, from small ranch homes to commercial buildings.
Negative-Air Source Removal
The negative-air method matters in Alvin because so much of what collects in ducts here is not ordinary household dust. It is fine silt from surrounding agricultural fields and particulate from the petrochemical corridor, mixed with humidity-driven mold growth. Brush-only cleaning, the kind done with hardware-store gear, releases that material back into the living space. A true negative-air setup captures it at the source and removes it from the home entirely.
Cleaning vs. Replacement After Water
After a flood or a major storm, Alvin homeowners need an honest assessment. Category 1 water from a supply line leak usually means cleaning and sanitizing is enough if the ducts dry quickly. Category 2 or 3 water, meaning floodwater or sewage-contaminated water, soaks duct insulation and interior lining, and that duct must be replaced. We inspect with a camera, document what we find, and give you a written report that distinguishes cleaning from replacement so your insurance claim is based on evidence, not guesswork.
Trusted Brands We Service in Alvin
We service and clean duct systems tied to every major HVAC brand found in Alvin homes, including the Carrier, Trane, Lennox, and Rheem units common in this market. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines, and we install Aprilaire and Honeywell filtration media when a homeowner wants better particulate capture after a cleaning. We stock common duct fittings, sealants, and filter sizes for Alvin jobs, so most repairs are completed the same day we start.
Common Air Duct Cleaning Problems We See in Alvin Homes
- Dirty sock syndrome in older subdivisions: After a wet spring, the first hot week in Alvin brings calls from homeowners along Highway 35 whose AC kicks on with a musty, sour odor. That smell is microbial growth on the coil and inside ducts, and it is especially common where drainage is poor and crawl spaces stay damp. Cleaning the ducts without treating the coil means the smell returns in weeks.
- Attic insulation pulled into supply runs: In 1960s – 80s brick ranch homes, retrofitted AC systems often have supply runs that were never properly sealed. Gaps at the plenum pull in attic insulation and dust, which re-contaminates ducts immediately after cleaning. We seal those runs as part of the job, not as an upsell.
- Fine agricultural dust in newer builds: Even newer Alvin homes with tight envelopes pull in fine silt from surrounding fields during the spring and fall shoulder seasons when windows are open. That dust coats the interior of flex ducts and the blower wheel. A standard filter change does not address it; source removal cleaning does.
- Rusted metal duct sections in older homes: Years of Gulf Coast humidity condensing on uninsulated metal ducts in crawl spaces causes rust-through, especially near the supply plenum. Once a section rusts through, cleaning is not enough. The section gets replaced, and we document the damage for your records.

FAQs About Air Duct Cleaning in Alvin
You should have your ducts inspected within 3 – 7 days after floodwater recedes from your home, and before you run the AC system again. Running the system pushes moisture and contaminants through the ductwork and into the living space, which spreads the problem and increases the chance of mold growth. We schedule post-flood inspections for Alvin homeowners on a priority basis and document what we find with camera footage so you have a record for your insurance claim. Call (713) 936-5800 and we will get you on the schedule.
Yes, and we document it in writing. After a storm in Alvin, we run a camera through the duct system and look for three things: the category of water that entered, whether interior insulation or lining has been saturated, and whether the duct material itself has been compromised. Category 1 water that dried quickly usually means cleaning and sanitizing is enough. Saturated duct insulation or floodwater contamination means replacement. We give you a written assessment with photos so your insurer has evidence, not just our word. Call (713) 936-5800 for an inspection.
That smell is almost always microbial growth on the AC coil or inside the ducts, a condition people in the trade call dirty sock syndrome. It is common in Alvin because the humid subtropical climate keeps ducts cool and damp for nine or ten months a year, especially in older subdivisions west of Highway 35 where drainage is poor. The fix is source removal cleaning that treats the coil and the ducts, not just an air freshener or a filter change. Call (713) 936-5800 and we will inspect the system and quote the work in writing.
We use the negative-air method with mechanical agitation. A Nikro negative-air machine puts the entire duct system under vacuum, then a Rotobrush rotary brush agitates the interior walls to release decades of dust, silt, and biological growth. The debris is pulled into HEPA filtration instead of blowing into your living room. Before we finish, we inspect every accessible joint and seal any gaps that were pulling attic insulation into the system. That is the part most cleaning companies skip, and it is why the smell comes back. Call (713) 936-5800 for a written quote.
It helps significantly, but only if the cleaning uses true source removal. The fine silt from Alvin’s surrounding agricultural fields and the particulate from the petrochemical corridor is small enough to pass through standard filters and settle in ducts and on the blower wheel. Brush-only cleaning releases that material back into the house. Negative-air cleaning with HEPA filtration removes it from the system entirely. We also recommend high-efficiency filtration media, and we stock Aprilaire and Honeywell options for Alvin homeowners who want better particulate capture after the cleaning. Call (713) 936-5800 to schedule.
