Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterCommercial Duct Cleaning in Round Rock, TX
Commercial duct cleaning in Round Rock covers the inspection, mechanical agitation, and negative-pressure extraction of debris, microbial growth, and contaminants from the air distribution system inside a commercial building – offices, retail suites, restaurants, medical clinics, and multi-unit properties included. A properly scoped commercial job is not Residential Duct Cleaning scaled up; the duct geometry, air volumes, and code considerations are different enough that the process has to be planned separately. At CleanRun Duct Repair & Cleaning, every commercial job starts with a written price before any equipment comes off the truck – Haven Standard Clause 1, no exceptions – and ends with a documented photo record of every duct run so the building manager has a verifiable record, not a verbal assurance.
If you manage a commercial space in Round Rock and want a straight number before committing to anything, call us at (737) 259-5752. A live person answers every call. No voicemail, no callback queue.
This page covers commercial duct work specifically. For residential service, our Air Duct Cleaning in Round Rock page walks through what that scope looks like and what it costs.
When You Need Commercial Duct Cleaning
Commercial duct systems in Round Rock accumulate debris faster than most building managers expect, partly because of the region’s climate. Central Texas pulls in significant outside air from April through October, and that air carries fine limestone particulate from construction sites – Round Rock has had active development along Gattis School Road, University Boulevard, and the Dell Diamond corridor for years. That particulate settles in return plenums and collects on coil faces before most tenants notice anything. Here are the situations where a commercial clean is typically overdue:
- Visible debris at supply registers or return grilles. If grey or brownish residue is collecting on register louvers, the duct interior is almost certainly carrying a heavier load. In most Round Rock office builds we’ve inspected since 2013, visible register debris correlates with a minimum of 2-3 inches of compacted material at the first upstream elbow.
- Occupant complaints about air quality or odors that HVAC filter changes haven’t resolved. A new filter addresses what’s entering the system going forward; it does nothing for what’s already coating the duct walls and accumulating in the plenum. If complaints persist after a filter upgrade, the duct interior needs to be looked at with a camera.
- Post-renovation or post-construction dust contamination. Drywall dust, joint compound, and insulation fibers migrate into open duct sections during interior buildouts. Round Rock’s commercial tenant improvement market is active enough that this is one of the most common triggers we see for commercial duct work in the city’s office parks near I-35 and Toll 45.
- Measured increases in HVAC energy consumption with no change in occupancy or thermostat settings. A debris-coated evaporator coil loses heat-transfer efficiency. In Round Rock’s summer conditions – where cooling loads run hard from late May through September – a partially blocked coil can add measurably to monthly utility costs. Cleaning the duct system and the coil face together is often the most cost-effective first step before replacing equipment.
- Evidence of microbial growth or musty odor in specific zones of the building. Texas humidity combined with commercial roof leaks or condensate drain issues creates conditions where biological growth can establish inside duct liner. If the smell is localized to specific supply zones rather than the whole building, the duct interior in those runs needs to be photographed before any sanitizing is considered.
- No documented cleaning in more than five years. NADCA guidelines recommend commercial systems be cleaned on a cycle appropriate to their occupancy type and use intensity. A restaurant kitchen exhaust duct and a low-traffic insurance office are different cases, but if there is no documented record of a previous clean – written scope, before-and-after photos, written price – it’s reasonable to treat the system as uncleaned regardless of what the previous service provider claimed.
Our Commercial Duct Cleaning Process
The following is what actually happens on a CleanRun Air Duct Cleaning job in Round Rock, described in sequence. No step is skipped to hit a lower price point; if a step can’t be completed within the agreed scope, we say so in writing before starting.
- Pre-job inspection and written scope delivery. Before any equipment enters the building, a CleanRun technician photographs the accessible duct sections, supply and return registers, and the air handler unit. The camera goes into the first available duct run to document existing conditions. The written price and scope – describing which runs are included, what equipment will be used, and what the job record will contain – is delivered and signed before work begins. This is Haven Standard Clause 1. There is no version of a CleanRun job where work starts before the customer has a number in writing.
- System isolation and negative-pressure setup. The air handler is shut down and isolated from the duct system. Negative-pressure extraction equipment – typically a Nikro or Abatement Technologies unit matched to the cubic footage of the system – is connected at the main trunk or plenum. Negative pressure means the system is under suction during the entire agitation phase, so dislodged material moves toward the collection unit rather than redistributing through the building. All supply and return registers not being actively worked are temporarily sealed.
- Mechanical agitation, run by run. Each duct run is agitated with rotary brush equipment and compressed air whips to break debris loose from duct walls and liner. The sequence moves from the farthest registers back toward the air handler so that material is always moving toward the extraction point. In fiberglass-lined duct – common in Round Rock commercial builds from the late 1990s through the 2010s – agitation technique is adjusted to avoid liner damage; the technician documents liner condition as part of the photo record regardless of whether damage is present.
- Air handler, coil, and plenum cleaning. The supply and return plenums are vacuumed and brushed. The evaporator coil face is cleaned of accumulated debris – in Central Texas, coil fouling is nearly universal on commercial systems that haven’t been cleaned in three or more years. The air handler cabinet interior is photographed before and after this step. Drain pan condition is checked and documented; standing water or visible growth in the drain pan is flagged in the written report.
- Post-clean camera verification and photo record compilation. After extraction is complete and the system is restored to operation, a camera pass is made through the duct runs included in the scope. Before-and-after photos are compiled into the job record, which is delivered to the building manager or property contact at job completion. This is not an optional add-on; it is a standard deliverable on every CleanRun job, documented since our first job in 2013. If a run does not show a clean result, it is re-cleaned before the job is closed.
- Written job record and 365-Day Done Right Promise delivery. The completed job record – written scope, before-and-after photo documentation, written warranty – is provided to the customer before the truck leaves the property. The 365-Day Done Right Promise covers the work in writing: if something within the scope of the job is not done correctly, CleanRun makes it right. This is a written commitment, not a policy subject to manager approval.
BeforeAfterCommercial Duct Cleaning Pricing in Round Rock
Commercial duct cleaning in Round Rock typically runs between $450 and $2,800 depending on system size, duct configuration, and the condition of the system at the time of service. The ranges below reflect what CleanRun has quoted on commercial jobs in Round Rock and the surrounding Williamson County area. Every number on this page is a real range from real jobs – not a teaser price designed to get a truck in the door.
| Building/System Type | Typical Range | Notes |
|---|---|---|
| Small office suite (under 2,000 sq ft, single RTU) | $450 – $750 | Single rooftop unit, limited duct runs, accessible from interior |
| Mid-size office or retail (2,000 – 5,000 sq ft) | $750 – $1,400 | Multiple zones, may include coil cleaning; liner condition affects time |
| Large office, medical clinic, or restaurant (5,000 – 12,000 sq ft) | $1,400 – $2,800 | Multiple air handlers, complex plenum geometry, or exhaust duct inclusion |
| Post-construction contamination surcharge | +$150 – $400 | Drywall dust and construction debris require additional extraction passes |
| Sanitizing application (if indicated) | +$120 – $350 | Applied only after mechanical cleaning; quoted separately |
Several factors move a quote within these ranges:
- Number of duct runs and supply/return registers. More registers mean more access points and more agitation passes. A 3,500-square-foot office with a single open-plan layout has fewer runs than the same footprint divided into a dozen private offices.
- Duct material and liner condition. Sheet metal duct cleans faster than duct board or flex with degraded liner. If the camera shows liner separation or prior water intrusion, additional time is required and noted in the written scope before work starts.
- System access. Rooftop units, crawlspace duct runs, or duct chases buried in concrete slab – which appear in some older Round Rock commercial builds near the Old Settlers Boulevard area – add complexity that is priced honestly before the job starts.
- Contamination level. A system that was last cleaned four years ago in a low-traffic professional office is a different job than a restaurant system or a building that went through a recent interior renovation.

FAQs – Commercial Duct Cleaning in Round Rock
How long does a commercial duct cleaning take at a Round Rock property?
Most commercial duct cleaning jobs in Round Rock take between three and eight hours, depending on system size and contamination level. A single-zone office suite under 2,000 square feet is typically complete in three to four hours. A multi-zone system in a medical clinic or restaurant with exhaust duct included can run a full day. CleanRun provides a time estimate in the written scope delivered before work starts, so the building manager can plan access and tenant communication accordingly. Call (737) 259-5752 for a written scope and time estimate specific to your property.
Can commercial duct cleaning be done after hours or on weekends to avoid disrupting tenants?
Yes, after-hours and weekend scheduling is available for commercial jobs in Round Rock. The HVAC system does need to be shut down during the job, which makes after-hours scheduling the practical choice for occupied medical clinics, restaurants, and retail spaces where daytime shutdowns aren’t workable. After-hours scheduling is noted in the written scope and priced at the time of quoting – there are no surprise surcharges added after the fact. Call (737) 259-5752 to discuss scheduling for your building.
What is the difference between commercial duct cleaning and a standard HVAC filter change?
A filter change addresses what enters the duct system going forward from the point of replacement. Full System Cleaning removes what has already accumulated inside the duct walls, plenums, and coil face over the system’s operating history. In practical terms, a new filter does not reduce debris that is already coating duct liner two bends past the air handler; it simply stops additional material from entering. CleanRun’s process uses negative-pressure extraction and mechanical agitation to remove existing accumulation and documents the result with before-and-after photographs so the building manager can see the actual difference, not just take our word for it.
Does CleanRun serve commercial properties across Round Rock, or only specific areas of the city?
CleanRun serves commercial properties throughout Round Rock – including properties near the Tech Ridge and Dell campus area, the Old Settlers Park corridor, Gattis School Road, University Boulevard, downtown Round Rock near Mays Street, and the newer commercial developments along Toll 130 and 45. If your building is in Williamson County and you’re not certain whether we cover it, call (737) 259-5752 and we’ll confirm coverage and give you a written price on the same call.
Why CleanRun for Commercial Duct Cleaning in Round Rock
CleanRun has been operating in Round Rock since 2013. In that time we’ve documented the inside of duct systems in office parks off I-35, restaurants in the La Frontera area, medical suites near St. David’s Round Rock Medical Center, and retail spaces throughout the city’s commercial corridors. The pattern we see most often is a system that was serviced by a low-bid provider with no photo documentation and no written warranty, where the building manager has no record of what was actually done or what the duct looked like when the crew left.
That’s the gap CleanRun was set up to fill. The documented photo record is included on every job, not sold as a premium option. The written price is delivered before work starts, every time. The 365-Day Done Right Promise is in writing on every job record. And the equipment – Nikro extraction units, Abatement Technologies collection systems – is the kind of professional-grade tooling that building managers can look up independently before agreeing to a price.
