AfterSupply Duct Cleaning in Houston, TX
Supply duct cleaning in Houston typically runs $285 to $520 for a full system, depending on home size, duct condition, and whether the return side needs work too. The job usually takes 3 to 5 hours, and it’s the single most effective step a homeowner can take to stop a fine layer of dust from settling on furniture within days of dusting. If you’re noticing dust buildup on supply registers or a musty smell when the AC kicks on, call Hollis Air Duct Houston at (713) 936-5800 and we’ll give you a written price before any work starts.
Supply ducts are the network of metal or flex tubing that carries conditioned air from your air handler to each room. When those ducts are dirty, every cooling cycle pushes whatever’s inside them, dust, pet hair, construction debris, sometimes mold spores from Houston’s humidity, straight into the rooms where your family sleeps and eats. Our full-service Air Duct Cleaning in Houston covers both supply and return sides, but this page focuses on the supply run because that’s the half that determines what you’re actually breathing.
Roy Castellanos leads the Hollis Air Duct Houston crew. Every technician is background-checked, uniformed, and trained on professional-grade equipment from Rotobrush and Nikro, not residential hardware-store attachments. We’ve been at this since 2004 under the Garrison Partners name, offering our Air Duct Cleaning services with prices in writing before we touch a single vent.

When You Need Supply Duct Cleaning
Most Houston homeowners don’t think about their supply ducts until a symptom shows up. Here are the signs we hear about most often from customers in Katy, Sugar Land, the Heights, and Clear Lake:
- Dust returns within 48 hours of cleaning. You wiped the dresser on Saturday. By Monday there’s a visible film. That dust is being delivered by your supply ducts every time the blower runs. In Houston, where AC cycles constantly from April through October, this is the single most common complaint we hear.
- Supply registers have visible dust buildup or dark streaking. Take the register cover off and look inside with a flashlight. If you see gray or brown coating on the duct walls, that’s what’s blowing into the room. Dark streaking near the register face often means fine particulates are being pushed through a gap or leak at the boot connection.
- Musty smell when the system first kicks on. Houston’s humidity breeds microbial growth inside ducts that stay cool and damp. If the first few seconds of airflow smell like a wet towel, the supply side likely needs attention. This is especially common in homes near the bayous, Galveston Bay, or any neighborhood where slab foundations hold moisture.
- One or two rooms are noticeably dustier than the rest. A partially collapsed or leaking supply branch can depressurize a section of the home, pulling attic dust or wall-cavity debris into that room’s air stream. We see this in older homes throughout the Energy Corridor and Memorial where original flex duct has sagged over time.
- Recent renovation or construction. Drywall dust, sawdust, and debris from a remodel get pulled into the return side and blown out through the supply ducts. Even a small bathroom update can load supply runs with fine particulate that takes months to fully purge without mechanical cleaning.
- Unusually high energy bills without a change in behavior. A heavily loaded supply duct system makes the blower work harder against reduced airflow. When supply runs are clogged, your system runs longer cycles to hit the same setpoint. Cleaning restores designed airflow and can drop static pressure readings noticeably.
None of these are cosmetic issues. They’re mechanical and air quality problems, and they don’t fix themselves. The longer supply ducts run loaded, the more deeply debris gets embedded in the duct liner and the harder it becomes to remove without professional negative-air equipment.
Our Supply Duct Cleaning Process
The Garrison Code is the standard every Hollis Air Duct Houston technician works to. It means we arrive inside the quoted window, price the job in writing before we start, complete the work by the book, and leave the site clean. Here’s what happens on a typical supply duct cleaning job, including our Video Inspection process:
- Walkthrough and written quote. Roy or one of our lead technicians walks the home with you, identifies the supply plenum, counts supply runs and registers, and checks for obvious leaks or damage at accessible boots. You get a written price on the spot. That number does not move at the door.
- System prep and protection. We lay down floor protection at the equipment location, confirm the thermostat is off, and seal access points with our Nikro negative-air machine connected to the supply plenum. Negative air means the system is under suction during cleaning, so loosened debris is pulled into a HEPA-filtered collection unit, not blown into your living room.
- Mechanical agitation of supply runs. We feed a Rotobrush rotary brush system through each supply run from the register boot back toward the plenum. The brush agitates the duct walls, knocking loose embedded dust, pet hair, and debris. The negative-air vacuum simultaneously captures it at the collection point. This is the same approach commercial duct cleaners use in hospitals and office towers, and we run it on 1,800-square-foot single-family homes.
- Register and boot cleaning. Every supply register is removed, cleaned, and wiped down. We clean the interior of each boot where the duct meets the register, which is where years of dust and grime collect. In Houston, boots are often rusted or damaged from condensation, so we flag any that need replacement and give you a price for that work separately if you want it.
- Final inspection and airflow check. We walk each room with you to confirm airflow from every supply register is strong and even. If a run isn’t performing after cleaning, we investigate for disconnects, kinks, or blockages before we pack up. The job isn’t done until every supply register is moving air the way it should.
- Site cleanup and follow-up documentation. We remove our equipment, clean up any debris, and leave the site the way we found it, minus the dust in your ducts. You get a summary of what was found and what was done, and every job is covered by the 365-Day Done Right Promise in writing.
Supply Duct Cleaning Pricing in Houston
Here’s How Much Does Air Duct Cleaning Cost in Houston, TX? (2026 Price Guide) for supply duct cleaning in the Houston metro, including the Heights, Katy, Sugar Land, Pearland, Clear Lake, and the Energy Corridor. These are real ranges, not teaser numbers:
| Service | Typical Price Range | What’s Included |
|---|---|---|
| Supply duct cleaning only (up to 10 runs) | $285 – $395 | All supply runs, boots, and registers cleaned with negative-air capture |
| Supply + return duct cleaning (full system) | $395 – $520 | Both sides of the system, all registers, boots, and plenums |
| Supply duct cleaning + dryer vent | $365 – $475 | Complete supply cleaning plus a full dryer vent cleaning |
| Duct sealing (mastic) add-on | $180 – $340 | Sealing leaks at supply boots and accessible joints to stop attic air intrusion |
| Register replacement (per register) | $12 – $28 | New stamped steel or aluminum register in matching finish |
What moves the price within those ranges? Home size and run count are the big ones. A 1,200-square-foot ranch in Spring Branch with 8 supply runs costs less than a 4,200-square-foot two-story in Katy with 18 runs. Duct condition matters too: heavily loaded ducts or runs with pet hair and construction debris take longer to clean properly. If your supply boots are rusted or the flex duct has collapsed in the attic, that’s repair work and it gets priced separately, in writing, before anything happens. See How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Houston, TX for full pricing details.
We don’t do the $49 whole-house special. That’s a bait number, and no crew running a $49 special is actually cleaning 15 supply runs with professional negative-air equipment. Our price is the price. You’ll know it before we touch a tool, and it stays the same when the job is done.

FAQs – Supply Duct Cleaning
How much does supply duct cleaning cost in Houston?
Supply duct cleaning in Houston costs $285 to $395 for up to 10 runs, and $395 to $520 for a full system that includes the return side. The exact price depends on home size, run count, and duct condition. We give you a written quote before any work starts, and that price does not change at the door. Call (713) 936-5800 for a free estimate.
Can you clean supply ducts the same day I call?
In most cases, yes. We keep same-day and next-day slots available for Houston homeowners, and our phones are answered by a live person 24/7. If you call in the morning, we can often have a technician at your home that afternoon. Tell the person who answers you need same-day supply duct cleaning and they’ll tell you exactly what’s available.
Is it cheaper to clean just the supply ducts or the whole system?
Cleaning only the supply side saves $110 to $125 compared to a full supply and return cleaning. But in most Houston homes, the return side is just as loaded as the supply side, so cleaning only the supply ducts often means you’re pulling dirty return air through a clean supply system within months. We’ll show you the condition of both during the walkthrough so you can decide with facts, not a sales pitch.
How long does supply duct cleaning take?
Most supply duct cleaning jobs in Houston take 3 to 5 hours, depending on run count and how heavily the ducts are loaded. We arrive inside the quoted window, protect your floors, run the full negative-air and rotary brush process, and leave the site clean. You don’t need to leave the house, and you don’t need to move furniture beyond giving us clear access to the registers.
Will supply duct cleaning reduce dust in my Houston home?
Yes, in most homes it’s the single biggest visible change after a cleaning. Supply ducts are the final leg of the air delivery path, so cleaning them removes the dust, pet dander, and debris that gets blown directly into your rooms. If your home has a separate problem, like deteriorating insulation in the attic or leaking duct boots pulling attic dust, we’ll flag it during the job and tell you what it costs to address.
Why Houston Homeowners Call Hollis Air Duct Houston
Houston’s climate is hard on ductwork. High humidity, long cooling seasons, and fine Gulf Coast dust mean supply ducts in this city load up faster than almost anywhere else in the country. A system that might run clean for years in Dallas or Austin needs attention every 3 to 5 years in Houston. When you add in the construction boom, new subdivisions all over Cypress, Tomball, and Richmond keep throwing drywall dust into the air, the supply side takes a beating.
We’ve worked in this environment since 2004. Roy Castellanos and the Hollis Air Duct Houston team are part of the Garrison Partners family, and every job runs to The Garrison Standard: arrive inside the quoted window, price in writing before any work starts, complete the job by the book, and leave the site clean. The 365-Day Done Right Promise backs every job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit.
Our equipment isn’t a hardware-store attachment on a shop vac. We run Rotobrush rotary brush systems for agitation and Nikro negative-air machines for containment, the same class of gear commercial duct cleaning crews use on office buildings and medical facilities. For homes that need filtration work, we’re familiar with Honeywell and Aprilaire systems and can recommend approaches that match what’s already installed on your air handler.
If you’re ready to get the dust out of your supply ducts, call (713) 936-5800. A live person answers 24/7. We’ll schedule a walkthrough, give you a written price, and clean your supply ducts by the book.
