AfterCommercial Duct Cleaning in Fort Worth, TX
Commercial duct cleaning in Fort Worth typically costs between $0.25 and $0.50 per square foot, with most office and retail spaces running $1,200 to $4,500 depending on system size and access. The job usually takes one to three days for a mid-size building, and the goal is straightforward: remove the built-up dust, debris, and biological growth that recirculates through your HVAC system every time the blower kicks on. At Hollis Air Duct Fort Worth, we bring the same written-price, done-right standard to commercial jobs that we bring to residential Air Duct Cleaning, using negative-air machines and rotary brush systems built for long runs of ductwork, rooftop units, and multi-zone systems. If you manage a building in Fort Worth and want a straight answer on your system, call (682) 255-2572 and we’ll give you a written price before any work begins.
We’re part of the Garrison Partners family, in business since 2004. We don’t do teaser bids that double at the door. Roy Castellanos runs this location by The Garrison Code: arrive inside the quoted window, price the job in writing, do it by the book, and leave the site clean. That applies whether we’re cleaning the ducts in a 2,000-square-foot dental office on Camp Bowie or a warehouse off I-35W with 600 feet of spiral duct.
When You Need Commercial Duct Cleaning
Commercial buildings in Fort Worth face a specific set of duct problems. The clay-heavy soil around Tarrant County throws fine dust into the air, and the hot summers force HVAC systems to run at full load for months. That combination loads duct interiors faster than most building owners expect. Here’s what tells us a system is due:
- Visible dust on supply diffusers and ceiling tiles. If you’re wiping dark streaks off diffusers near the Stockyards or downtown, the ducts feeding them are already carrying that same material into the breathing zone.
- Occupant complaints about stale air or allergy symptoms. When three different employees in the same suite complain about the same symptoms, the ductwork is often the common denominator. We hear this a lot in older buildings near the Medical District where duct liners have been collecting dust since the 1980s.
- Renovation or tenant turnover. Drywall dust, paint overspray, and construction debris travel through return ducts during build-outs. The spaces around Sundance Square and West 7th see constant churn, and a post-construction duct cleaning is standard practice before new tenants move in.
- Reduced airflow from registers. A duct liner that has separated or a return that’s packed with debris reduces the CFM your unit was designed to move. If one zone in a Fort Worth office building is always 8 degrees off from the others, there’s a restriction somewhere in the duct path.
- Odors that persist after filter changes. A musty or sour smell that returns a week after the filters are swapped usually means mold or debris is sitting inside the duct itself, not the filter media. The humidity Fort Worth gets from spring through early fall amplifies this problem.
- Higher energy bills without higher occupancy. A clogged coil and dirty blower wheel force the compressor to run longer. We clean the blower assembly and the coil as part of the duct job, because a clean duct feeding a dirty fan is a half-done job.
Our Commercial Duct Cleaning Process
We don’t run a vacuum hose into one register and call it a day. Here’s the process we follow on every commercial duct cleaning in Fort Worth, whether it’s a medical office in the Near Southside or a restaurant kitchen exhaust supply line in the Cultural District, as part of our Full System Cleaning:
- Walkthrough and written proposal. Roy or one of our technicians walks the building, checks access points, identifies rooftop units or mechanical closets, and gives you a written price before any work starts. That price does not change at the door.
- System isolation and negative-air setup. We deploy a Nikro negative-air machine to put the duct system under negative pressure. That means dust and debris get pulled into a HEPA-filtered containment unit instead of blowing into occupant spaces. This is the same method commercial remediation crews use, scaled to your building.
- Mechanical agitation of duct walls. We run a Rotobrush rotary brush system through the supply and return ducts. The rotating brushes knock loose the dust caked onto the duct walls, and the negative-air machine captures it at the source. For long commercial runs, this beats a glorified shop vac every time.
- Blower wheel, coil, and drain pan cleaning. The ductwork is only part of the air path. We pull and clean the blower assembly, wash the evaporator coil, and clear the drain pan and line. A dirty coil keeps blowing mold spores into clean ducts if you skip this step.
- Filter check and recommendation. We inspect the current filtration. If your building runs basic 1-inch filters on a commercial system, we’ll show you the dust loading numbers and recommend a media filter upgrade from Honeywell or Guardsman, matched to your CFM and static pressure.
- Post-cleaning verification and site cleanup. We run the system, verify airflow at registers, and leave the mechanical room and occupied areas as clean as we found them, usually cleaner. If anything’s not right, you have our 365-Day Done Right Promise in writing.
Commercial Duct Cleaning Pricing in Fort Worth
Here’s what commercial duct cleaning costs in Fort Worth right now, based on the jobs we price every month. These are honest ranges, not teaser numbers that move once the technician arrives:
| Building Type | Typical Size | Price Range |
|---|---|---|
| Small office or retail space | 1,000 – 2,500 sq ft | $900 – $1,800 |
| Mid-size office or medical suite | 2,500 – 7,500 sq ft | $1,800 – $3,500 |

| Restaurant kitchen exhaust supply lines | Varies by hood and duct run | $600 – $2,200 |
What moves the price in Fort Worth: the number of rooftop units or air handlers, the total linear feet of duct, how accessible the ductwork is, whether the system has interior duct liner (common in older buildings around TCU and the Near Southside), and the level of contamination, including whether you need Return Duct Cleaning. A post-construction job with heavy drywall dust costs more than a routine 10-year cleaning on a well-maintained system. We give you the written price after the walkthrough, and it stays that price.

FAQs – Commercial Duct Cleaning
How much does commercial duct cleaning cost in Fort Worth?
Residential Duct Cleaning is a separate service; commercial duct cleaning in Fort Worth typically runs $0.25 to $0.50 per square foot, with small offices starting around $900 and large spaces reaching $6,500 or more. The main variables are system size, number of units, access difficulty, and contamination level. We provide a written price after a free walkthrough, and that price does not change once work begins. Call (682) 255-2572 to schedule a site visit.
How long does commercial duct cleaning take?
Most mid-size commercial duct cleaning jobs in Fort Worth take one to two days, while larger buildings with multiple rooftop units can take up to three days. We schedule the work around your operating hours, and for buildings that can’t shut down during the day, we work nights and weekends. The written quote includes the timeline, so you know what to expect before we start.
Is commercial duct cleaning worth it for a Fort Worth building?
For most commercial buildings in Fort Worth, yes, especially if the system hasn’t been cleaned in 5 to 10 years or the building has seen recent renovation work. Clean ducts improve airflow, reduce the dust load on coils and blowers, and eliminate a common source of occupant complaints. The payback comes through lower energy use, fewer tenant complaints, and a longer equipment life. If you’re not sure whether your system needs it, we’ll tell you straight, even if the answer is no.
Can you clean ducts while our business is open?
Yes, we clean commercial ducts while your Fort Worth business stays open in most cases. The negative-air method contains dust at the source, so we don’t blow debris into occupied areas. For restaurants, medical offices, or any building where noise is a concern, we schedule around your peak hours. Tell us your operating constraints when you call, and we’ll build the schedule around them.
Do you guarantee commercial duct cleaning work?
Every commercial duct cleaning job we do in Fort Worth is covered by the 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit. That guarantee is in writing on every job, not a verbal promise. It’s part of The Garrison Standard that Roy Castellanos runs this location by.
