Commercial Duct Cleaning in Dallas, TX

Commercial duct cleaning in Dallas typically costs between $1,200 and $4,500 depending on square footage, system complexity, and how long it’s been since the last cleaning. We finish most office, retail, and light industrial jobs in one to two days, and we give you a written price before any work starts. If you’re managing a building where the HVAC has been neglected, call (361) 309-6223 and we’ll walk the space, check the ductwork, and put the number on paper that day.

Hollis Air Duct Dallas handles commercial Air Duct Cleaning for offices, clinics, restaurants, churches, retail spaces, and warehouses across the Dallas metro. The work is done by background-checked, uniformed technicians using the same negative-air and rotary brush equipment we run on residential jobs, scaled up for bigger systems. Every commercial job is covered by our 365-Day Done Right Promise, which means if the work fails within a year, we come back and make it right at no charge. Written down. On paper. The way it should be.

Key Takeaways: Commercial Duct Cleaning in Dallas

• Cost range: $1,200 to $4,500 for most Dallas commercial spaces; large industrial jobs or hard-pipe retrofits may run higher.
• Time on site: Most jobs finish in one to two days, depending on system size and access.
• Experience matters: Hollis has done this since 2004, as part of the Garrison Partners family, and every job follows The Garrison Code: arrive inside the window, price it in writing before touching anything, and leave the site clean.
• Guarantee: 365-Day Done Right Promise, in writing. If it fails, we return at no charge, including a free second visit.
• Equipment: Negative-air machines from Nikro, paired with rotary brush systems, plus filtration hardware from Honeywell and Aprilaire. Professional-grade equipment, not hardware-store gear.

When You Need Commercial Duct Cleaning

Dallas buildings see a lot in a year: pollen season that coats everything yellow, dry dust blown in from the west, humidity that feeds mold inside the ductwork, and constant air conditioning load during the long summers. A commercial HVAC system pulls that in, filters some of it, and pushes the rest through the building, which is why Full System Cleaning matters for every component. Here’s what tells us it’s time to clean:

• Visible dust around supply registers or return grilles. If the ceiling tiles near a vent show gray streaks, the duct run behind them is carrying dust into the space.
• Employees or tenants complaining about stale air, allergies, or headaches. When multiple people in the same zone report the same symptoms, the shared variable is almost always the air delivery system.
• Higher energy bills without a change in occupancy or usage. A coil caked with dust and debris makes the system run longer to hit the same setpoint. That cost shows up monthly.
• Renovation or tenant turnover. Construction dust, drywall fines, and old tenant debris collect in returns and supply runs. New tenants deserve clean ductwork on move-in day.
• Musty or oily smells when the HVAC kicks on. Odors are particles. If the system smells, the source is in the air stream, and cleaning is the only way to get it out.
• It’s been more than three to five years. For commercial spaces in Dallas with continuous AC load, we recommend cleaning every two to four years. If you’re not sure when it was last done, it’s probably due.

Our Commercial Duct Cleaning Process

We don’t do “blow and go” work. The equipment leaves the rack, the ducts get cleaned with the same rigor we bring to Residential Duct Cleaning, and the site gets left the way it should look: no drop cloths left behind, no dust blown into occupied areas, no surprises. Here’s the method, step by step, in plain terms.

1. Site walk and system review. Before any price is written, we walk the mechanical room, check the air handler, note duct runs and access points, and identify what type of cleaning the building actually needs. That includes checking for flex duct, hard pipe, or a mix.
2. Written scope and price. We put the job on paper: what gets cleaned, how long we expect it to take, and what it costs. That number does not move at the door. You approve it, we start. That’s The Garrison Standard.
3. Containment and negative air. We set up a Nikro negative-air machine to pull the system under negative pressure. That keeps loosened debris from escaping into occupied spaces. The contaminated air is pulled from the building and exhausted outside, not redistributed through your office.
4. Rotary brush cleaning and agitation. We run a rotary brush system through supply and return runs, agitating caked-on dust, skin cells, construction debris, and whatever else has accumulated. The loosened material moves through the duct to our collection point at the negative-air machine.
5. Coil and blower cleaning, if needed. If the system is far enough gone that the evaporator coil or blower wheel is caked, we clean them while the system is down. A clean coil does more for efficiency than any duct cleaning alone.
6. Site check and verification. We walk the building with you, show you what we pulled out, confirm the system is running, and leave the space clean. The fill port goes back on, the panels go back up, and there’s no trace we were there except cleaner air.

Commercial Duct Cleaning Pricing in Dallas

What commercial duct cleaning costs in Dallas depends on three things: square footage served, number of air handlers, and how accessible the ductwork is. Here are the ranges we typically quote, based on what we’ve seen across Dallas, Garland, Irving, Mesquite, and the surrounding suburbs.

Building Type	Typical Range	What’s Included
Small office (under 5,000 sq ft)	$1,200 – $2,200	1-2 air handlers, supply and return cleaning, coil inspection
Mid-size office or retail (5,000 – 15,000 sq ft)	$2,200 – $3,800	2-4 air handlers, full duct cleaning, coil and blower cleaning
Large commercial or light industrial (15,000 – 40,000 sq ft)	$3,800 – $6,500	Multiple air handlers, all duct runs, mechanical room cleanup, verification walk
Industrial or special-use (kitchens, labs, factories)	Quoted after site walk	Variable: depends on grease load, chemical exposure, or specialized containment

Those numbers assume standard access. If your duct runs are buried above a hard ceiling, that changes the labor. If the building has been a restaurant or a print shop, the contaminant load changes the process and the time. We’ll tell you all of that in the written scope before you commit to a dollar.

What Affects Commercial Duct Cleaning Cost in Dallas

• Number of air handlers. Each air handler is a system. Cleaning one is different from cleaning six.
• Access difficulty. Hard ceilings, rooftop units, long ladder runs, and confined mechanical rooms all add labor.
• Contaminant type. Dry dust cleans fast. Grease, mold, or construction debris takes longer and demands more containment.
• Age of the system. Older flex duct sometimes tears during cleaning. We’ll tell you before we start if that’s a risk, and we’ll price the repair separately, in writing.
• After-hours scheduling. If we need to work nights or weekends to avoid disrupting your business, that’s a planning conversation, not a price surprise. We’ll quote it up front.

Why Dallas Businesses Choose Hollis Air Duct Dallas

We’re not the only company in the Dallas phone book that cleans commercial ductwork. We know that. We don’t compete to be the cheapest, and we don’t run bait-and-switch ads where a $79 special turns into a $2,000 invoice once the technician is in the building. We compete on discipline.

Roy Castellanos leads the operation here, and he runs every job the same way: show up inside the quoted window, put the price on paper before touching the system, do the work by the book, and leave the space clean. The Garrison Code is a list of behaviors, not adjectives. It says the technician arrives on time, in uniform, with a background check on file. It says the system gets cleaned, not just vacuumed at the registers. It says if something fails within a year, we come back at no charge and make it right.

The equipment matters too. We run Nikro negative-air machines, not shop vacs. We use rotary brush systems that physically agitate the inside of the duct, including the Return Duct Cleaning runs, not just a wand that blows air around. If your building has filtration needs, we carry Honeywell and Aprilaire products, and we’ll explain in plain terms what a media filter or an Aprilaire unit will do before you spend a dollar on one.

We’ve been in business since 2004. The commercial jobs we do are repeat work: the same office building manager calls us back every two years, because the first cleaning was done the way it should have been done. The same facility director refers us to the next property, because the invoice matched the estimate and the crew didn’t leave a mess. That’s how we’ve kept the phone ringing for two decades.

Does Your Insurance or Lease Require Duct Cleaning?

Some Dallas commercial leases require duct cleaning at tenant turnover. Some insurance carriers require it after a water event or a fire. If you’re in a situation where you need documentation, we provide a written scope, a completion report, and photos of the work. That documentation holds up when a landlord or an insurance adjuster asks for proof that the system was actually cleaned, not just “serviced.”

If you’re not sure what your lease or policy requires, call us and tell us the situation. We’ll help you figure out what you need, and we’ll only recommend the work that actually needs doing. Roy won’t sell you a cleaning you don’t need just because a lease clause could be read loosely.

Commercial Duct Cleaning FAQs

How much does commercial duct cleaning cost in Dallas?

Commercial duct cleaning in Dallas runs $1,200 to $4,500 for most buildings under 40,000 square feet, with small offices starting around $1,200 and larger commercial spaces running to $6,500 or more depending on the number of air handlers and access difficulty. Every Hollis quote is written down before work starts, and the price does not change at the door. Call (361) 309-6223 and we’ll schedule a site walk for a written quote.

How often should a commercial building have its ducts cleaned?

In Dallas, where air conditioning runs most of the year and pollen and dust load the system heavily, commercial ducts should be cleaned every two to four years. Restaurants, clinics, and buildings with high foot traffic or heavy dust load may need it annually. If you’re not sure when yours were last cleaned, we’ll inspect the system and tell you what we find, in plain terms, before recommending a schedule.

Can you clean our ducts without shutting down the business?

Yes. For most occupied offices and retail spaces, we can work after hours or on weekends, and the negative-air containment keeps the work from blowing dust into open areas. The site walk is free and the quote is in writing, so you’ll know the schedule and the cost before you commit to anything.

Is commercial duct cleaning worth it?

If your ducts are carrying dust, mold spores, or construction debris into occupied spaces, cleaning removes the source instead of masking the symptom. A dirty evaporator coil can add 10 to 30 percent to your cooling bill, and that’s a cost that shows up every month. For tenants with complaints about air quality, clean ductwork is one of the few fixes that addresses the actual mechanical delivery system. Call (361) 309-6223 and we’ll help you figure out if cleaning is the right step, and exactly what it will cost.

Commercial Duct Cleaning in Dallas: What to Check Before You Hire

If you’re comparing our quote against another Dallas company, check three things. First, is the price written down before the work starts, and does it stay the same at the door? A verbal quote is a starting position, not a commitment. Second, what equipment do they actually run? A shop vac and a flashlight is not negative-air duct cleaning, and the difference shows up in the air quality afterward. Third, what happens if the work fails? Most companies give you a shrug. We give you a written 365-Day Done Right Promise: if it’s not done right, we make it right, for a full year, at no charge, including a free second visit.

We’ll answer those questions for ourselves, in writing, on the front of every proposal. That’s the standard Roy Castellanos set for this location, and it’s the standard every technician who walks into a Dallas building under the Hollis name is expected to meet.

Call (361) 309-6223 for a free commercial duct cleaning estimate in Dallas. A live person answers, 24/7, not a voicemail loop and not a call center. We’ll get your building scheduled, quoted in writing, and cleaned right the first time.
