When You Need Commercial Duct Cleaning
Business ducts collect what the business generates. A restaurant pulls grease vapor into the return duct plenum. A gym pulls sweat-laden air, chalk dust, and skin cells into the handler. A print shop pulls paper fiber and toner fines. None of it stays put. Here is what we see before we’re called:
- Visible dust accumulating around supply registers within days of a wipe-down. That’s not housekeeping falling behind. That’s the ductwork feeding particulates back into the space every time the blower cycles on.
- A stale, sour, or “stuffy” smell when the HVAC runs. In Austin’s heat, condensation inside duct runs creates a humid microclimate. Add organic debris and you get microbial growth that announces itself every cycle.
- Staff complaining of sinus irritation, headaches, or coughing only while at work. Repeated complaints tied to the building, not the season, point at the air distribution system.
- Uneven airflow between offices, front-of-house, and back-of-house. A buildup of debris in branch ducts restricts airflow long before the filter catches anything. One room feels fine; the next feels like a sauna by 2 p.m.
- An energy bill that climbs without an obvious cause. Restricted ducts force the blower to work harder. In a commercial space with a 10-ton rooftop unit, that’s real money, month after month.
- You have tenants, patients, customers, or inspectors asking about air quality. A dated, documented commercial duct cleaning from a named company answers the question better than any verbal assurance.
Our Commercial Duct Cleaning Process
We use professional-grade equipment, not attachments bolted onto a shop vac. Rotobrush rotary brush systems dislodge debris at the duct wall. Nikro negative-pressure units pull contaminants out of the duct run rather than pushing them into the occupied space. Abatement Technologies HEPA filtration traps the loosened particulates so they stay out of your building. Here’s the sequence:
- Walkthrough and equipment survey. We inspect the rooftop units, air handlers, supply and return plenums, and accessible duct runs. We note ceiling height, access point locations, and any areas that need special handling (kitchens, server rooms, exam rooms). We look at the filters and note what is getting past them.
- Written quote, before work begins. You get a line-item price in writing. No door-step revision, no “discovered something” surcharge after we start. The Kingswell Way is specific: say the price, then honor the price.
- Containment and negative-air setup. We seal supply and return registers within the work zone, connect the Nikro negative-pressure unit, and establish the airflow direction so any dislodged debris travels toward the collection unit, not into your space.
- Brush agitation and debris removal. We run the Rotobrush system through each accessible duct run to break the particulates loose from the duct walls. The negative-air unit pulls the loosened material out continuously. For larger runs, we open access points and clean section by section.
- Plenum, coil, and blower cleaning. The ductwork is only part of the system. We clean the supply and return plenums, the evaporator coil, and the blower assembly on accessible units. A clean duct attached to a dirty coil defeats the work within a month.
- Filter check and final verification. We replace or recommend replacement filters, confirm airflow at each register, walk the job site with you, and leave the space as clean as we found it. Every job includes the 365-Day Done Right Promise in writing.
Commercial Duct Cleaning Pricing in Austin
Commercial duct cleaning in Austin is priced by the square foot of conditioned space and the complexity of the ductwork. The honest range for most commercial jobs in Austin runs between $0.33 and $0.55 per square foot. Here is how that breaks down for common Austin commercial spaces:
- Small office or retail (2,000 – 4,000 sq ft): $660 – $2,200. One or two rooftop units, accessible ceiling, standard 8 – 10 ft ceiling height. Most jobs take 4 – 8 hours.
- Mid-size office, clinic, or restaurant (4,000 – 8,000 sq ft): $1,300 – $4,400. Multiple rooftop units, longer duct runs, kitchen exhaust considerations. Most jobs run a full day or two.
- Large commercial or light industrial (8,000 – 15,000 sq ft): $2,600 – $8,250. Multiple air handlers, high ceilings, extensive branch ducting, possible lift or scaffold work. Two to three days.
What pushes a commercial job toward the top of the range:
- Ceiling heights above 12 feet that require lifts or scaffolding.
- Restaurant kitchens with grease-laden return air, which slows brush work and demands more cleanup.
- Ductwork that has not been cleaned in 10+ years and has significant buildup at the wall.
- Multiple rooftop units spread across a large footprint.
- Restricted access points that require additional openings to be cut and sealed.
Every commercial quote is line-item and in writing before we begin. You will not be surprised. We also offer full system cleaning and Honeywell and Aprilaire filtration options if you want to keep particulates out of the cleaned system between service visits.

FAQs – Commercial Duct Cleaning
How much does commercial duct cleaning cost in Austin?
Commercial duct cleaning in Austin typically runs $0.33 – $0.55 per square foot, so most jobs fall between $900 and $2,800 for small-to-mid-size commercial spaces and up to $8,250 for larger facilities. The exact number depends on ceiling height, number of rooftop units, and how much buildup is present. Call (254) 848-6913 for a free walkthrough and a written quote.
How long does commercial duct cleaning take?
Most commercial jobs in Austin take one to two working days, depending on square footage and system complexity. A small office with one rooftop unit can be done in a single day. A large restaurant or multi-tenant building may take two to three days. We schedule around your business hours and can work nights or weekends when the space is unoccupied.
Can we stay open during commercial duct cleaning?
Most Austin businesses stay open during cleaning, though we may seal off sections of the work zone for a few hours at a time. The negative-air setup directs debris into the collection unit, not into your space, so staff and customers are not exposed to the material being removed. For restaurants and medical offices, we typically schedule residential-style duct cleaning after hours or on closed days to minimize disruption.
Is commercial duct cleaning worth the cost?
For most Austin businesses, yes. The payback comes from lower HVAC operating costs, better airflow, fewer staff complaints about stale or dusty air, and cleaner surfaces between janitorial visits. If you are seeing visible dust at supply registers or a rising energy bill, the duct cleaning pays for itself within a season or two. Call us at (254) 848-6913 and we will tell you honestly if your ducts need cleaning or if something else is causing the problem.
