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 Lewisville, TX
Commercial Air Duct Cleaning in Lewisville removes accumulated dust, biological debris, and contaminants from the supply and return air systems in office buildings, retail spaces, restaurants, and light-industrial facilities – using negative-pressure extraction equipment and rotary agitation tools sized for commercial duct dimensions. Most Lewisville commercial jobs run between $800 and $3,200, depending on square footage and system configuration, and are completed without shutting down your operation. Every job CleanRun Air Duct Cleaning Lewisville takes on starts with a written price – before a panel comes off – and ends with a Documented Photo Record of every duct run.
If you’ve been handed a $79 coupon from another company, call us at (940) 240-8552 and we’ll put our own written number next to theirs at no cost. That’s the Free Second Opinion, and it’s available on any written estimate. Our broader Air Duct Cleaning in Lewisville service covers both residential and commercial work – this page focuses specifically on what commercial jobs require, why they’re different, and what you’ll actually receive when CleanRun’s crew leaves your building.
Tomas Reyes has led CleanRun under the H.A.V.E.N. Standard since 2013. In that time, we’ve completed documented cleanings across more than 52,000 properties, every one with a written price before work started and a photo record when the crew left. Commercial work in Lewisville – from the office parks near I-35E to the retail corridors along FM 3040 – is a regular part of what we do, and the documentation standard doesn’t change based on the building type.
When You Need Commercial Duct Cleaning
- Visible dust accumulation at registers or grilles. When supply registers in a Lewisville office or retail space show visible dust buildup on louvers, that debris is already cycling through the occupied space with every air handler cycle. It’s not cosmetic – it’s an indicator of what the camera will find deeper in the plenum (the main distribution chamber connected to the air handler).
- Occupant complaints about air quality or odors. If employees or customers report stuffiness, musty smells, or recurring respiratory irritation and HVAC filters have been recently replaced, the source is often in the duct runs themselves – particularly in Lewisville’s humid summer months, when moisture can enter ductwork through poorly sealed joints and promote microbial growth.
- Post-renovation or post-construction cleanup. Drywall dust, insulation fibers, and wood particulate from tenant improvements travel through open duct systems during construction. North Lewisville commercial corridors near Castle Hills and Hebron Parkway see constant tenant buildout activity, and a post-construction cleaning before occupancy is standard for any responsible property manager.
- Recent pest or rodent activity in the building. HVAC ductwork is a common nesting and travel corridor for rodents and insects in commercial buildings. When pest control confirms activity, duct cleaning is the required follow-up – the debris, nesting material, and biological contamination left behind doesn’t clear on its own and will cycle through the air system indefinitely if not extracted.
- Documented HVAC efficiency decline. When your HVAC equipment is running longer cycles to hit setpoints and filter replacements haven’t corrected the issue, debris-restricted airflow is a likely factor. A Nikro negative-pressure extraction – which draws air through the entire system at volume rather than just vacuuming registers individually – typically reveals the restriction source within the first hour of setup.
- Scheduled maintenance intervals for occupied commercial buildings. The National Air Duct Cleaners Association (NADCA) recommends commercial duct inspection every two to five years, with cleaning based on findings. High-traffic Lewisville commercial spaces – restaurants, medical offices, gyms – often need cleaning closer to that two-year mark because particulate load is higher.
Our Commercial Duct Cleaning Process
-
Written Scope and Price – Before Any Work Begins
Haven Standard Clause 1 applies to every job, commercial or Residential Duct Cleaning: you receive a written price before a single access panel comes off. For commercial work, this starts with a walkthrough of your mechanical room, air handler locations, duct layout, and approximate linear footage of duct runs. We account for system size, number of zones, register count, and access complexity. The written scope documents exactly what will be cleaned, what equipment will be used, and what the final deliverable looks like. There is no “call for a quote” at CleanRun – the number goes on paper before we touch anything.
-
Pre-Cleaning Camera Inspection and Baseline Documentation
Before extraction begins, a camera is run through the accessible duct runs to document baseline conditions. This is not a sales tool – it’s the first half of the Documented Photo Record that you receive as part of the standard job deliverable. What the camera shows (a measured debris layer at the first elbow, biological growth near a poorly sealed joint, construction dust packed against a damper) is what drives the scope. If the camera shows clean ductwork, we tell you that in writing and you don’t pay for cleaning you don’t need.
-
Negative-Pressure Setup and Source Containment
Negative-pressure extraction means a large-diameter collection hose is connected directly to the main trunk line or plenum, and a high-volume vacuum unit – using Nikro professional-grade equipment on commercial jobs – draws air through the entire system toward a single collection point. This matters because it prevents dislodged debris from being redistributed into the building during cleaning. Registers and grilles are temporarily sealed during this phase. For commercial buildings in Lewisville, we size the extraction unit to the system – undersized residential shop-vac units create the noise without the negative pressure that makes cleaning effective.
-
Rotary Agitation and Duct Run Cleaning
With negative pressure established, a Rotobrush agitation system is introduced into each duct run. The rotating brush head breaks up adhered debris – compacted dust, mold colonies, construction particulate – while the negative-pressure system draws it toward the collection point rather than back into the building. Each supply run and Return Duct Cleaning run is worked individually. We do not skip runs to save time, and the post-cleaning camera confirms each one before we move to the next.
-
Register, Grille, and Air Handler Cleaning
After duct runs are cleared, registers and return-air grilles are removed, cleaned, and reinstalled. The air handler cabinet – including evaporator coil area, blower compartment, and drain pan – is inspected and cleaned as part of a Full System Cleaning. Debris that accumulates on the evaporator coil forces the system to work harder and can hold moisture that promotes biological growth. This step is not an add-on; it’s part of a complete commercial cleaning.
-
Post-Cleaning Documentation and Written Delivery
The camera goes back through every run after cleaning. The before-and-after photos from each duct run are compiled into the Documented Photo Record and delivered to the building owner or property manager as part of the job record – not as a marketing piece, but as an accountable record of what was completed. If the post-cleaning camera shows anything that doesn’t meet the scope, it’s addressed before the crew leaves. That’s the 365-Day Done Right Promise in practice: the work is accountable after the truck is gone, but it starts with documentation that confirms the job was done before we leave.
BeforeAfterCommercial Duct Cleaning Pricing in Lewisville
Commercial duct cleaning in Lewisville is priced based on four variables: system size (measured in square footage of conditioned space or total duct linear footage), number of air handlers and zones, degree of contamination found during the pre-cleaning inspection, and access complexity. Written pricing is delivered before work begins – always, with no exceptions under Haven Standard Clause 1.
| Building / System Type | Typical Lewisville Price Range | What Drives the Number |
|---|---|---|
| Small office suite (under 2,500 sq ft, 1 air handler) | $800 – $1,200 | Register count, single-zone system, standard access |
| Mid-size office or retail (2,500 – 6,000 sq ft, 2 handlers) | $1,200 – $2,000 | Multi-zone, rooftop unit access, higher run count |
| Restaurant or food-service space | $1,400 – $2,400 | Grease-laden air, makeup air ductwork, more frequent cleaning required |
| Large commercial (6,000+ sq ft, 3+ handlers) | $2,200 – $3,200+ | System complexity, rooftop unit count, access panel fabrication if needed |
| Post-construction commercial cleaning | $1,000 – $2,500 | Construction debris load, system size, whether ductwork was protected during build |
These ranges reflect actual Lewisville market conditions as of 2025-2026. A company quoting a flat $79 or $199 for commercial duct cleaning is either limiting the scope to a partial cleaning (a few registers, no trunk lines) or planning to expand the price once they’re inside. CleanRun’s written price covers the full scope documented in the walkthrough – no line items appear after work starts.

FAQs – Commercial Duct Cleaning in Lewisville
How long does a commercial duct cleaning take in Lewisville?
Most Lewisville commercial duct cleanings take between three and six hours, depending on system size and contamination level. A single-zone office suite under 2,500 square feet typically runs three to four hours from setup to post-cleaning camera documentation. Multi-zone systems with rooftop units – common in the Lewisville retail and office park corridors near Vista Ridge Mall and I-35E – can run five to seven hours. The pre-cleaning inspection and walkthrough add roughly 20-30 minutes before the clock starts on the cleaning itself. We don’t compress timelines to fit a schedule; the post-cleaning camera confirms each run is clear before we call the job done. Call (940) 240-8552 for a timeline estimate specific to your building’s system configuration.
Does commercial duct cleaning disrupt business operations?
In most cases, no – the negative-pressure extraction process keeps the work contained to mechanical and duct access areas, and occupied spaces stay usable during cleaning. Registers are sealed temporarily during the extraction phase, which means conditioned air isn’t distributed during that portion of the work, but the disruption is brief and localized. For Lewisville restaurants or medical offices where air quality during service hours is critical, we can schedule work during off-hours or early mornings. That scheduling preference is noted in the written scope before work starts – nothing changes after the job is confirmed. Call (940) 240-8552 to discuss timing for your specific building.
How often should a Lewisville commercial building have its ducts cleaned?
NADCA guidelines recommend commercial duct inspection every two to five years, with cleaning based on what the inspection finds. In Lewisville, high-traffic or high-particulate environments – restaurants, gyms, medical clinics, any space with frequent exterior door traffic during spring cedar and elm pollen season – typically need cleaning closer to the two-year mark. Standard office space in a tightly sealed building often runs closer to three to four years between cleanings. The pre-cleaning camera inspection at the start of every CleanRun job tells you objectively what’s there; if the system is clean, you don’t pay for cleaning it didn’t need. Call (940) 240-8552 and we’ll schedule an inspection and give you a written finding before any cleaning scope is discussed.
What credentials should I verify before hiring a commercial duct cleaning company in Lewisville?
At minimum, verify that the company carries commercial general liability insurance, that technicians are background-checked, and that the company can name the equipment it uses – not just “professional equipment.” Ask for the written price before any work begins; any company that can’t produce one in writing before entering the building is a risk to your property and your budget. CleanRun operates under Haven Standard Clause 3 (Verified Crews): every technician is background-checked, uniformed, and identified by name before arrival. We use Rotobrush and Nikro equipment on commercial jobs – both are trade-recognized brands you can look up independently before agreeing to any scope. Tomas Reyes leads every commercial engagement and is reachable directly at (940) 240-8552.
