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 Katy, TX
Commercial duct cleaning in Katy, TX covers the inspection, mechanical agitation, and negative-pressure extraction of contaminants from supply and return duct systems in office buildings, retail suites, restaurants, medical facilities, and light industrial spaces. A properly documented commercial cleaning takes longer, requires larger-diameter equipment, and produces a different kind of deliverable than a residential visit – a written job record that facility managers and building owners can file, share with tenants, or present to inspectors. At CleanRun Air Duct Cleaning Katy, every commercial job starts with a written price before any panel comes off, and finishes with a photo record of every Return Duct Cleaning run as a standard deliverable. If you need a quote now, call (346) 666-7165 – a live person answers every call.
Katy’s commercial corridors along I-10, the Grand Parkway, and Mason Road see a mix of buildings that create specific duct problems. Strip centers built during the mid-2000s construction boom often have flex duct that has never been cleaned and is now partially collapsed at the joints. Medical and dental offices near the LaCenterra district deal with high-occupancy air loads that push particulate through the system faster than the filter change schedule accounts for. Restaurants off Fry Road accumulate grease aerosols in the supply side of the system – a problem that shows up clearly in camera footage and is a genuine fire and code concern. Whatever the building type, our approach is the same: document what is there, price the work in writing, do the job with professional-grade equipment, and photograph the result. That is the whole standard.
This page covers our commercial duct cleaning service specifically. If you are looking for residential service or want the broader picture of what we offer in this area, the Air Duct Cleaning in Katy page is the right starting point.
When You Need Commercial Duct Cleaning
Some of these situations are obvious from inside the building. Others only become clear when a camera goes into the duct run. Here are the most common scenarios we see across Katy commercial properties:
- Visible debris at registers or diffusers. When supply diffusers are blowing visible dust or dark particulate into occupied space, the duct system is past its cleaning interval. In Katy buildings with high seasonal pollen loads – particularly during March and October oak and grass pollen peaks – filter bypass around undersized grilles makes this happen faster than most facility managers expect.
- Persistent odors that don’t clear with HVAC cycling. Grease film inside restaurant supply ducts, mold colonies on fiberglass duct liner, and accumulated biological debris all produce odors that do not respond to air fresheners or filter swaps. Camera inspection locates the source; extraction and, where indicated, antimicrobial treatment addresses it.
- Post-construction or post-renovation cleanup. Drywall dust, adhesive overspray, and insulation fibers settle into duct systems during any build-out. Several tenant improvement projects in Katy’s I-10 West corridor have come to us after occupancy because the GC’s standard cleaning missed the duct interior entirely. The camera footage in these cases is usually straightforward to interpret.
- HVAC efficiency drop without obvious mechanical cause. When airflow at terminal diffusers drops and the mechanical equipment is functioning normally, debris restriction in the duct runs is a logical first diagnostic step. A 3-inch debris accumulation at the first elbow off the plenum – which we photograph before quoting any remediation – can cut effective airflow by a measurable fraction.
- Tenant complaints about air quality or allergy symptoms. In a multi-tenant strip center or office building, one complaint from one suite often signals a system-wide condition. Katy’s commercial buildings along the Energy Corridor feeder roads see this frequently, particularly in buildings where HVAC zones were modified during tenant buildouts without corresponding duct work adjustments.
- Pre-sale, pre-lease, or inspection-driven documentation requirements. Property transactions and commercial lease renewals increasingly include HVAC condition as a disclosed item. A documented photo record from a CleanRun commercial cleaning gives both parties a timestamped baseline – something a verbal assurance from a previous vendor does not provide.
Our Commercial Duct Cleaning Process
We follow a consistent, documented sequence on every commercial job. The specifics vary by building size, duct configuration, and material type, but the structure does not change.
- Written scope and price before any work starts. A technician walks the mechanical space, counts duct runs, identifies access points, and photographs the plenum – that is the central distribution chamber the main air handler feeds into – before writing a price. The written quote is delivered to the facility contact with line-item detail. Haven Standard Clause 1 covers this without exception: no work starts without a signed written price. There is no “call for a quote” stage at CleanRun. The number is on paper before anyone picks up a tool.
- Pre-cleaning camera inspection of key runs. Before extraction begins, we run a camera into the main supply trunk and a representative sample of branch runs to document existing conditions. This footage becomes part of the job record. For facility managers who need to show a property owner or tenant what the system actually contained, this step is the difference between a credible report and a verbal claim. The camera footage shows debris depth, liner condition, and any visible moisture or biological growth.
- Negative-pressure extraction with professional-grade equipment. We connect a high-volume vacuum collection system – negative-pressure extraction means the vacuum draws air through the duct toward the collection unit, so dislodged debris travels toward containment rather than back into occupied space. For commercial jobs, we use equipment rated for the duct diameter and linear footage involved. Rotobrush and Nikro equipment are both part of our commercial toolkit; the specific configuration depends on duct geometry and material. Flex duct runs require a different brush speed and pressure profile than sheet metal trunk lines, and we adjust accordingly.
- Mechanical agitation of duct walls. The vacuum alone does not dislodge compacted debris from duct walls, seams, or elbows. Rotary brushes – sized to the duct diameter – mechanically break the debris loose so the negative-pressure system can carry it out. At each elbow and transition, the technician works in sections rather than running through the full run in a single pass. This is the step that separates documented cleaning from what the industry sometimes calls “vacuum noise.”
- Plenum and air handler coil area cleaning. The plenum and the area immediately downstream of the air handler coil are where contamination concentrates. Surface debris on an evaporator coil face reduces heat-transfer efficiency in a way that downstream duct cleaning alone does not fix. We clean these surfaces as part of the commercial scope and photograph the condition before and after.
- Post-cleaning camera verification and photo record delivery. After extraction is complete, the camera goes back into the same runs documented at the start. The before-and-after photos become the job record – delivered to the facility contact as a standard deliverable, not an optional add-on. This is the documentation that goes in the building file and, if needed, in front of a property manager, inspector, or tenant. Every CleanRun commercial job has produced this record since our first job in 2013.
BeforeAfterCommercial Duct Cleaning Pricing in Katy
Commercial duct cleaning in Katy, TX is priced per job based on duct linear footage, system configuration, access difficulty, and building type – not on a per-vent rate the way some Residential Duct Cleaning pricing works. The variables are real and they affect the labor time significantly. Here is what the ranges look like for common building types in this market:
| Building / Space Type | Typical Size Range | Estimated Price Range |
|---|---|---|
| Small office suite (single-tenant) | 1,000 – 3,000 sq ft | $450 – $950 |
| Mid-size retail or medical office | 3,000 – 8,000 sq ft | $900 – $2,200 |
| Restaurant (supply side, non-hood) | Varies by layout | $1,100 – $2,800 |
| Multi-tenant strip center (full building) | 8,000 – 20,000 sq ft | $2,000 – $5,500 |
| Light industrial / warehouse office section | Varies significantly | Quoted on inspection |
These ranges reflect Katy market conditions and the cost of doing the job with professional-grade equipment and a documented photo record included. They are not the price you get from a $79-coupon operation, and they are not inflated to leave room to negotiate down. The written quote you receive before work starts is the number.
What moves a job toward the higher end of a range:
- Duct systems with significant liner damage that requires more careful brush speed management to avoid further deterioration
- Access restrictions – dropped ceilings with small tiles, mechanical rooms with limited entry, or rooftop units that require additional setup time
- Buildings with rooftop package units common in Katy’s strip centers, where duct runs often pass through unconditioned plenum spaces and accumulate more debris than ground-level systems
- Post-construction cleaning where debris volume is significantly higher than a maintenance cleaning
- Antimicrobial treatment applied to duct surfaces after extraction, when camera inspection shows biological growth

FAQs – Commercial Duct Cleaning in Katy
How often should a commercial building in Katy have its ducts cleaned?
Most commercial buildings in Katy benefit from cleaning every 3 to 5 years under normal operating conditions, but the interval depends heavily on building type and use. Restaurants and medical facilities typically need cleaning every 1 to 2 years due to higher airborne contamination loads – grease aerosols in restaurant supply runs and elevated particulate in medical waiting areas both accelerate accumulation. Buildings that went through a renovation since the last cleaning should be inspected regardless of schedule, because construction debris settles into duct systems in a matter of days. Camera footage at the pre-cleaning inspection tells us more about the actual condition than any calendar-based rule does. Call (346) 666-7165 to schedule an inspection and get a written assessment.
Is commercial duct cleaning different from what you do in a house?
Yes, in several practical ways. Commercial systems use larger-diameter duct – sheet metal trunk lines in a commercial building are typically 12 to 24 inches across, compared to 6 to 10 inches in most residential branch runs – so the Full System Cleaning equipment sizing and vacuum capacity have to match. Commercial buildings also have multiple air-handling units, rooftop package units common in Katy strip centers, and zoning configurations that require the job to be planned by section rather than run as a single continuous pass. The documentation requirement is also different: facility managers and property owners typically need a written record for their files, which is why the photo record and written job scope are built into the CleanRun commercial standard on every job, not quoted as optional additions.
What does “negative-pressure extraction” actually mean, and why does it matter?
Negative-pressure extraction means the collection vacuum is connected to the duct system so that air inside the duct is moving toward the vacuum unit at all times during cleaning. When the rotary brush dislodges debris from the duct wall, that debris travels toward the containment unit rather than out through the registers into occupied space. It matters because the alternative – running a shop-vac at the register opening while someone pushes debris from the far end – pushes dislodged material back into the room. We use Nikro collection equipment on commercial jobs where duct diameter and run length require industrial-capacity extraction, and the setup is photographed as part of the job record.
Can you work around business hours so we don’t have to close?
In most cases, yes. Commercial cleaning is scheduled based on the building’s operational needs. We have completed cleaning work in occupied Katy office buildings during early morning hours before staff arrived, and in retail spaces during overnight windows. The scheduling specifics are part of the scope conversation when we do the walk-through and write the price. The work itself does generate some equipment noise during the agitation phase, so completely silent operation is not realistic, but access to individual zones can usually be sequenced to minimize disruption to occupied areas. Call (346) 666-7165 to discuss your building’s schedule.
Why Katy Businesses Choose CleanRun
The short answer is documentation. A lot of commercial property in Katy has had duct cleaning done at some point by someone – the question is what that cleaning actually consisted of and whether there is any record of it. A verbal assurance from a previous vendor is not a building record. A timestamped photo showing before-and-after conditions in each duct run is.
CleanRun has documented every job this way since 2013, across more than 52,000 jobs. Tomas Reyes built the company on the premise that a customer who can see the inside of their duct system before and after cleaning does not need to take anyone’s word for whether the work was done. That standard applies the same way to a 2,500-square-foot dental office on South Mason Road as it does to a 15,000-square-foot retail building near LaCenterra.
The H.A.V.E.N. Standard governs how every technician operates on site: background-checked, uniformed, identified by name before arrival. Haven Standard Clause 3 covers verified crews specifically. Haven Standard Clause 1 covers the written price before any work starts. These are not policies subject to manager approval; they are the operating standard on every Air Duct Cleaning job, commercial and residential alike.
