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 San Antonio, TX
Air duct cleaning in San Antonio typically runs between $800 and $4,500 depending on building size, system configuration, and the last time the ductwork was serviced – and CleanRun puts that number in writing before a single access panel comes off. We’ve documented the inside of commercial duct systems across San Antonio since 2013, and what the camera finds in an office plenum or restaurant return air chase is rarely what the building manager expects.
If your business has been getting complaints about air quality, struggling with HVAC efficiency, or you’re simply overdue on maintenance, this page covers what commercial duct cleaning actually involves, what it costs in San Antonio’s market, and how CleanRun’s documented process differs from a shop-vac crew with a coupon. For background on our full scope of duct work, the Air Duct Cleaning in San Antonio parent page explains how we approach every system – residential or commercial – with the same written price and photo record standard.

When You Need Commercial Duct Cleaning
Commercial systems accumulate debris faster than residential duct cleaning jobs – higher traffic, more occupants, kitchen exhaust nearby, and often ductwork that was installed decades ago and hasn’t been touched since. Here are the situations where San Antonio businesses typically call us:
- Visible dust discharge at registers: When supply registers blow visible particulate into the space, the main duct trunk or branch runs have accumulated enough debris that the airstream is carrying it out. In older office buildings along Loop 410 and downtown San Antonio, we’ve pulled cameras into plenums and found 2- to 4-inch debris packs at the first elbow off the air handler.
- Persistent odor complaints from staff or customers: A mold colony, accumulated biological material, or rodent activity inside ductwork produces an odor that no amount of air freshener touches. The source has to be documented and removed – not masked.
- Failing HVAC efficiency or rising utility bills: San Antonio’s heat means commercial HVAC systems run hard from April through October. When debris restricts airflow through the plenum or branch runs, the air handler works harder and longer to hit setpoint. That extra runtime shows up directly on the CPS Energy bill.
- Post-renovation or construction dust infiltration: Drywall dust, concrete particulate, and insulation fibers enter ductwork during commercial build-outs if the system isn’t properly isolated. We see this frequently in Pearl District and Midtown San Antonio buildings that have gone through tenant improvements.
- Health department, insurance, or lease requirement: Some San Antonio commercial landlords and certain industries – food service, medical, childcare – require documented duct maintenance on a defined schedule. A photo record from CleanRun satisfies that requirement in a way a verbal assurance cannot.
- New building acquisition or management change: If you’ve taken over a commercial property and have no maintenance history for the HVAC system, starting with a documented inspection and cleaning gives you a verified baseline – something you can show an insurer or a tenant.
Our Commercial Duct Cleaning Process
Commercial systems vary: a 3,000-square-foot retail space in Alamo Heights has different ductwork than a 20,000-square-foot warehouse near Brooks City Base or a medical office in the Stone Oak corridor. Our process adapts to the system, but the sequence and standards don’t change.
-
On-site assessment and written scope of work
Before any pricing is discussed, a CleanRun technician walks the building with you, identifies every air handler unit, maps the main trunk lines and branch runs, locates return air chases, and notes any visible damage or prior patchwork. That information produces a written price – line-itemed, not estimated – before work begins. Haven Standard Clause 1 applies to every commercial job: the written price is what you pay, full stop. -
Pre-cleaning camera documentation
We photograph the inside of every duct run before extraction begins. On commercial jobs this means every accessible trunk section, each branch run, and both supply and return sides of the air handler. These images are time-stamped and delivered to you as part of the standard job record. The before photos are the baseline – they show exactly what was present before we touched anything. -
Negative-pressure extraction with source-removal agitation
Negative-pressure extraction means we create a controlled vacuum across the duct system so that dislodged debris travels toward collection rather than back into the building. On commercial jobs we use Nikro and Rotobrush equipment – rotating brush systems that mechanically agitate debris from duct walls, combined with high-volume collection equipment that captures what’s dislodged. This is source removal, not surface sweeping. The difference matters: a vacuum wand at a register opening stirs debris; our system pulls it out. -
Air handler and coil inspection
The air handler is the heart of the system. We inspect the blower compartment, drain pan, and evaporator coil for biological growth, standing moisture, and debris accumulation. In San Antonio’s humidity – especially during the spring and early-summer months when dew points climb – the evaporator coil is a common site for mold formation. If we find growth, we document it photographically and present options in writing before any remediation work begins. We use Abatement Technologies equipment where HEPA-rated containment or negative-air applications are warranted. -
Register and grille cleaning, system reassembly
Every supply and return register is removed, cleaned, and reinstalled. Access panels are resealed to manufacturer specification. The system is returned to normal operation before the crew leaves, and no components are left open or tagged for follow-up without your written acknowledgment of why. -
Post-cleaning documentation and job record delivery
After cleaning, we run the camera through the same duct runs photographed before work began. The after images are compiled alongside the before images in a documented photo record that’s yours to keep – whether for your own files, your building management records, or a regulatory inspection. The 365-Day Done Right Promise is noted on your job record in writing: if the work isn’t right, we make it right.
BeforeAfterCommercial Duct Cleaning Pricing in San Antonio
Commercial duct cleaning in San Antonio is priced by system complexity, not by square footage alone – a 5,000-square-foot building with four air handler units and a maze of flex duct costs more to clean properly than a 10,000-square-foot open warehouse with two rooftop units and straight sheet-metal trunk lines. The ranges below reflect what CleanRun actually quotes for commercial work in the San Antonio market.
| Building Type / System Size | Typical Written Price Range |
|---|---|
| Small commercial space, 1 air handler, under 2,500 sq ft | $800 – $1,400 |
| Mid-size office or retail, 2-4 air handlers, 2,500-8,000 sq ft | $1,500 – $2,800 |
| Larger commercial building, 5+ air handlers, 8,000-20,000 sq ft | $2,800 – $4,500 |
| Documented mold remediation or post-construction cleaning (add-on scope) | Quoted separately in writing after inspection |
What Affects the Price
- Number of air handler units: Each unit requires its own blower and coil inspection. More units, more labor and time.
- Duct material and configuration: Flexible duct (common in San Antonio commercial builds from the 1980s and 90s) requires different agitation technique than rigid sheet metal. Improperly cleaned flex duct collapses under excessive vacuum – our crew adjusts pressure accordingly.
- Debris load and last service date: A system that hasn’t been documented as cleaned in five or more years will carry significantly more debris. The pre-cleaning camera tells us what we’re dealing with before we price any add-on scope.
- Access difficulty: Plenum access in a drop ceiling with dense mechanical runs costs more labor than a systems with open access panels. We photograph access conditions as part of the pre-work documentation.
- Sanitizing or antimicrobial application: If the camera documents biological growth, sanitizing is quoted as a separate line item – never rolled into a package price without your sign-off.

If you already have a written estimate from another company, we’ll provide a free second opinion – our price in writing, next to theirs.
FAQs – Commercial Duct Cleaning in San Antonio
How often should a commercial building in San Antonio have its ducts cleaned?
Most commercial buildings in San Antonio benefit from duct cleaning every 3 to 5 years, with systems in food service, medical, or high-occupancy environments typically requiring service every 2 to 3 years. San Antonio’s long cooling season means HVAC systems run more hours per year than in most U.S. cities, which accelerates debris accumulation in the plenum and branch runs. If your building has never had a documented cleaning – with before-and-after photos – starting with an inspection gives you an honest baseline rather than a guess. Call (726) 600-7155 and we’ll schedule a walk-through at no charge.
What’s the difference between commercial duct cleaning and a basic residential service?
Full system cleaning involves more air handler units, larger duct diameter and volume, more complex system layout, and often stricter documentation requirements than a residential job. The core process – negative-pressure extraction, source-removal agitation, camera documentation before and after – is the same standard CleanRun holds on every job. What changes is scale: a commercial job on a multi-unit building in the Medical Center area may involve six or more air handlers and hundreds of linear feet of trunk duct, each section photographed individually. The written price and 365-Day Done Right Promise apply exactly the same way.
Can CleanRun clean commercial ducts without shutting down the business?
In most cases, yes. We schedule commercial jobs around your operating hours – early morning, after close, or on weekends – and section the work by air handler unit so most of the building remains conditioned while one zone is being serviced. For businesses in San Antonio’s hospitality corridor or medical offices that can’t tolerate any operational interruption, we’ll put the scheduling plan in writing as part of the job scope before work begins. Call (726) 600-7155 to discuss your building’s specific constraints.
Does CleanRun provide documentation suitable for a health department inspection or lease compliance?
Yes. The Documented Photo Record CleanRun delivers on every commercial job – time-stamped before-and-after images of every duct run, air handler compartment, and register – is a concrete record of service, not a certificate with a logo on it. Several San Antonio commercial property managers and food-service operators use our job records for exactly this purpose. If your compliance requirement specifies a particular format or scope, tell us before work begins and we’ll confirm in writing whether our standard record meets it or whether additional documentation is needed.
