AfterCommercial Duct Cleaning in San Antonio, TX
Full System Cleaning for commercial properties in San Antonio typically costs between $0.25 and $0.50 per square foot, with most office and retail spaces landing in the $1,200 to $4,500 range depending on building size, duct configuration, and how long it’s been since the last cleaning. Morton’s Air Duct San Antonio has handled commercial systems across Bexar County since 2005, from small dental offices in Alamo Heights to restaurant kitchens along the River Walk. If you manage or own a commercial property and the vents haven’t been touched in years, call us at (903) 354-8393 and we’ll give you a written quote before any work begins.
Commercial duct cleaning is a different job than residential work, and it needs different equipment, different scheduling, and a crew that knows how to work around your business hours. That’s the work we do. You can also learn more about our approach on our Air Duct Cleaning page, which covers the fundamentals that apply to every building we service.
When You Need Commercial Duct Cleaning
Most commercial buildings in San Antonio share a few common signals that the ductwork needs attention. You’ll notice one or more of these before you ever call us:
- Dust accumulating on desks, shelves, and merchandise within days of cleaning. In dry San Antonio months, especially late summer when the AC runs nonstop, dust moves through ducts constantly. If your team wipes surfaces twice a week and they’re coated again, the ducts are recirculating debris.
- A musty or stale smell when the HVAC kicks on. High humidity in spring and fall creates condensation inside duct runs, and that moisture invites microbial growth. You smell it every time the system cycles.
- Uneven airflow between rooms or floors. Blocked return ducts and restricted supply lines force some areas to stay cold while others stay warm. Your tenants or employees notice the difference before afternoon.
- Visible dust or debris around vent covers and ceiling diffusers. If you can see particulates around the grille, the duct interior behind it is typically much worse.
- Higher energy bills without a change in usage. Restricted airflow makes your HVAC compressors work harder, and in San Antonio’s summer heat, that cost shows up on your CPS Energy bill fast.
- Tenant complaints about allergies, headaches, or stale air. Office workers in enclosed commercial spaces breathe whatever the ducts deliver. If complaints cluster, the air delivery system is usually the common thread.
When we’re called to a restaurant kitchen in the Pearl District or a storefront in Stone Oak, the problem is rarely a mystery. It’s ducts that have been ignored for five, ten, sometimes fifteen years. And it’s always fixable.
Our Commercial Duct Cleaning Process
Before any equipment comes off the truck, the plan is written down and the price is set. That’s how every Morton’s job starts, and commercial work is no exception. Here’s the process we follow on a typical commercial job in San Antonio:
- Walkthrough and written quote. We inspect the building, count the vents, check the return air paths, and measure the duct runs. Then we hand you a written price. No ranges that change later, no add-on surprise at the end.
- Scheduling around your business. We work before opening, after closing, or on weekends. For restaurants and clinics, that often means a late-night or Sunday shift. We’ll protect floors and work areas with drop cloths and shoe covers on every visit, including the path from the entry to the mechanical room.
- Source removal with professional-grade equipment. We run Rotobrush and Nikro systems through every supply and return line, dislodging debris and pulling it into a HEPA-filtered collection unit. For buildings with older or high-capacity systems, we pair the air sweep with negative pressure so nothing escapes into occupied spaces.
- Component cleaning. We clean registers, grilles, diffusers, coils, blower motor, and the return air plenum. Skipping the coil and blower is the most common mistake in cheap commercial duct jobs, and it’s exactly why so many building managers call us after another company “cleaned” the ducts a year ago.
- Post-clean visual documentation. Before the crew leaves, you get photos of the cleaned duct interiors and the work areas. That photo record is part of the Morton’s standard, not an upsell.
Every commercial job is backed by the 365-Day Done Right Promise. If the job isn’t right within a year, we make it right. That promise is stamped on every commercial invoice we write in San Antonio.
Commercial Duct Cleaning Pricing in San Antonio
Return Duct Cleaning pricing in the San Antonio market depends on three things: total square footage of ducted space, number of rooftop units or air handlers, and how accessible the ductwork is. Older buildings in areas like Government Hill or Monte Vista often have harder-to-reach runs, which adds labor time. Newer tilt-wall buildings on the Northwest Side are usually more straightforward.
| Building Type | Typical Price Range | Notes |
|---|---|---|
| Small office (under 3,000 sq ft) | $1,200 – $2,500 | 5 – 12 vents, 1 – 2 units; usually a half-day job |
| Medium office or retail (3,000 – 8,000 sq ft) | $2,500 – $4,500 | Multiple zones; may require an evening shift |
| Restaurant kitchen + dining | $2,000 – $5,000 | Grease and particulate buildup requires more passes |
| Medical or dental office | $1,800 – $3,800 | Often scheduled on weekends to avoid patient hours |
| Large facility (8,000+ sq ft) | $4,500 – $12,000+ | Custom quote after walkthrough |
These ranges reflect what we’ve quoted on commercial jobs across San Antonio in the past year. Your building will fall somewhere on this table, and the only way to know exactly where is a walkthrough. That walkthrough and quote are free. Call (903) 354-8393 and we’ll schedule it around your hours.
FAQs – Commercial Duct Cleaning
How much does commercial duct cleaning cost in San Antonio?
Commercial duct cleaning in San Antonio runs $0.25 to $0.50 per square foot, with most projects falling between $1,200 and $4,500. Your exact price depends on building size, number of HVAC units, and duct accessibility. Call (903) 354-8393 for a free walkthrough and written quote – you’ll know the price before any work starts.
How long does commercial duct cleaning take?
Most small-to-medium San Antonio commercial buildings are done in 4 to 8 hours. We schedule around your business hours, including nights and weekends, so you don’t have to close. Large facilities may take multiple shifts, and we’ll tell you the timeline in the written quote.
Is commercial duct cleaning worth the cost?
Yes, in most San Antonio commercial buildings. Clean ducts reduce the load on your AC system, which runs hard from May through September. The energy savings and reduced wear on rooftop units typically offset the cleaning cost within a year or two. What building managers also tell us: tenant complaints about air quality usually stop after a proper source-removal clean.
Do you clean ducts in restaurants and commercial kitchens?
We do. Restaurant duct systems collect grease vapor and fine particulates, and they require more passes and angled brushes than Residential Duct Cleaning or a standard office build. We use Rotobrush and Abatement Technologies equipment on these jobs, and we schedule them after the kitchen closes. The walkthrough quote is free, and the price is written before we touch a single vent.
Can you work around our business hours?
Yes. Most of our San Antonio commercial jobs happen before opening, after closing, or on weekends. Tell us your least disruptive window and we’ll build the schedule around it. Call (903) 354-8393 and ask for Paul – we’ll arrange a walkthrough that works for your team.
Why San Antonio Businesses Call Morton’s
We’ve been doing this work since 2005. In that time, we’ve learned that commercial clients in San Antonio don’t need someone to sell them fear about air quality. They need a crew that shows up when they said they would, protects the floors and work areas, uses professional equipment instead of entry-level rental gear, and hands over a written price before the job begins. That’s the job.
We work to the Cedarwell Care Promise on every commercial visit. Shoe covers and drop cloths inside the building. A written price before any work starts. A photo of the clean-up before the crew leaves. The C.A.R.E. values aren’t a poster in our office; they’re the checklist our technicians run through on the way to your mechanical room.
Our technicians are background-checked and arrive in uniform. When they walk into a medical office in the South Texas Medical Center or a childcare center in Alamo Ranch, you know exactly who’s in your building and what they’re doing there. And when the job is done, you get visual proof of the clean, not just a verbal “all good.”
Paul Adeyemi, our owner, answers his phone during business hours, and a live person answers 24/7. Not a voicemail tree, not a chatbot. A human being. Call (903) 354-8393 and you’ll speak to someone who can actually schedule the walkthrough.
If you’re ready to see what clean commercial ducts feel like in your building, start with the walkthrough. We’ll walk the space, count the vents, write the price, and put it in your hand. Then you decide. No pressure, no surprise invoice, no mess left behind.
