You’re losing up to 40% of your heating and cooling energy to clogged ducts. That’s not a guess—it’s what the U.S. Department of Energy found when they studied commercial HVAC systems. Dust, debris, and moisture don’t just sit there. They force your system to work harder, drive up your utility bills, and create the kind of indoor air that makes people sick.
Clean ducts mean your airflow improves by as much as 75%. Your system runs efficiently again. Your energy costs drop by 10% to 25% on average. And your employees stop dealing with the headaches, allergies, and respiratory issues that come from breathing recycled contaminants all day.
This isn’t about making your building smell better. It’s about protecting your bottom line, extending the life of expensive equipment, and keeping your team healthy enough to actually show up and work.
We’ve been handling commercial HVAC work across San Antonio, Somerset, and the surrounding area for over 30 years. We’re veteran-owned, which means we show up on time, do what we say, and don’t waste your day with runarounds or upsells.
Somerset’s commercial properties deal with Texas heat and humidity year-round. That combination accelerates dust buildup, promotes mold growth, and puts serious strain on duct systems. We’ve cleaned everything from small office buildings to large industrial facilities in this area, and we know what works.
Every technician on our team is certified, licensed, and insured. We offer transparent pricing before we start, and we’re available 24/7 if something goes wrong outside business hours.
We start with an inspection of your entire duct system—supply ducts, return ducts, and all the components in between. That means looking at your cooling coils, reheat coils, diffusers, grilles, and air handling units. We’re checking for blockages, moisture, mold, and the kind of buildup that kills airflow.
Once we know what we’re dealing with, we use commercial-grade equipment to remove contaminants. High-powered vacuums pull debris out while rotating brushes and compressed air tools dislodge stuck-on dust and grime. We clean every accessible section of your ductwork, not just the easy parts.
After cleaning, we can sanitize the system if needed and seal any leaks that are letting conditioned air escape. You’ll get a walkthrough of what we found, what we fixed, and what (if anything) needs attention down the road. The whole process usually takes one to three days depending on your building size, and we work around your schedule to minimize disruption.

You’re getting a full system cleaning—not a quick pass with a vacuum. That includes all supply and return air ducts, which are the main pathways moving air through your building. We clean your cooling coils and reheat coils, which are major collection points for dust and moisture. We address your diffusers, grilles, registers, and air handling units.
Somerset’s climate creates specific challenges. High humidity means moisture gets into your ducts and combines with dust to form sticky buildup. That’s a breeding ground for mold and bacteria, and it’s why so many commercial properties in this area see reduced airflow and higher energy bills. We’re targeting those problem areas specifically.
We also inspect for leaks and damaged sections that are wasting conditioned air. If your ducts need sealing or minor repairs, we’ll let you know upfront. And if you’re dealing with a compliance issue—OSHA, EPA, or ASHRAE standards—we document everything so you have records when you need them.
NADCA recommends cleaning every three to five years for most commercial buildings. But that’s a baseline, not a rule. If you’re running a restaurant, medical facility, or any space with high contamination risk, you’re looking at more frequent cleaning—sometimes quarterly or annually.
Somerset’s humidity accelerates the timeline. Moisture combines with airborne dust and pollen faster here than in drier climates, which means buildup happens quicker. If you’re seeing dust on vents, noticing musty odors, or dealing with employee complaints about air quality, don’t wait for the three-year mark.
The real answer depends on your building type, occupancy, and how hard your HVAC system works. We can give you a specific recommendation after inspecting your system.
Most commercial projects start around $1,000 to $2,000 and go up from there based on building size, duct complexity, and contamination level. A small office with straightforward ductwork costs less than a 50,000-square-foot warehouse with multiple air handlers.
You’re paying for labor, equipment, and time. A job might take one day for a small building or stretch into several days for larger facilities. If we find mold, significant debris, or damaged sections that need repair, that affects the scope and cost.
We give you a clear quote before starting any work. No surprises, no hidden fees. And if you’re comparing prices, make sure you’re comparing the same service—some companies only clean accessible ducts and skip the coils, which is where a lot of the problem actually lives.
Yes, but the savings depend on how dirty your system is right now. A 1987 ASHRAE study found that maintaining clean HVAC systems reduces operating costs by 10% to 25%. The U.S. Department of Energy says 25% to 40% of heating and cooling energy gets wasted when contaminants clog your system.
Here’s why: dirty ducts restrict airflow. Your HVAC has to run longer to reach the same temperature, which burns more energy. Dirty coils can’t transfer heat efficiently, so your system works even harder. All that extra runtime shows up on your utility bill.
After cleaning, airflow improves and your system doesn’t have to strain. Most commercial clients see a noticeable drop in energy costs within the first billing cycle. The dirtier your ducts were to start, the bigger the difference you’ll notice.
Your ducts are circulating whatever’s inside them. If that’s dust, mold spores, pollen, and bacteria, your employees are breathing it all day. The American College of Allergists found that 50% of illnesses are either caused or made worse by polluted indoor air.
Dirty air leads to real problems: respiratory issues, allergies, headaches, fatigue. People call in sick more often. Productivity drops. In some cases, you’re dealing with sick building syndrome, where employees only feel symptoms when they’re at work.
Cleaning removes the contaminants at the source. You’re not just masking the problem with air fresheners or filters—you’re eliminating the dust and biological growth that’s actually causing the issue. Cleaner air means fewer sick days, better focus, and a healthier work environment overall.
If you’re subject to OSHA or EPA indoor air quality standards, yes. Both agencies require routine maintenance of air handling systems, and that includes duct cleaning. ASHRAE also sets guidelines for commercial buildings, and NADCA provides the industry standards most inspectors reference.
Courts have consistently ruled that building owners have a legal obligation to provide safe, healthy indoor air. If an employee gets sick because of poor air quality and you haven’t maintained your HVAC system, you’re looking at liability issues, higher insurance premiums, and potential lawsuits.
We document everything during the cleaning process, so you have records showing you’ve met maintenance requirements. If you’re in a regulated industry—healthcare, food service, education—those records aren’t optional. They’re part of staying compliant and protecting yourself legally.
Scale and complexity. Commercial systems are bigger, more complicated, and handle higher volumes of air. You’re dealing with multiple air handlers, longer duct runs, larger coils, and equipment that runs constantly—not just a few hours a day like residential systems.
Commercial cleaning requires industrial-grade equipment and technicians who understand complex HVAC layouts. We’re not just vacuuming out a few vents. We’re accessing rooftop units, navigating mechanical rooms, and cleaning systems that might serve multiple floors or zones.
The stakes are higher too. A dirty residential system affects one family. A dirty commercial system affects dozens or hundreds of employees, impacts your operating costs, and can put you out of compliance with regulations. That’s why commercial duct cleaning costs more and takes longer—because there’s more to clean and more riding on getting it right.
