Why Indoor Air Quality Matters for Your Business
The air quality inside your commercial building has a direct impact on the people who spend their days in it. Studies from the EPA and Harvard T.H. Chan School of Public Health have consistently shown that poor indoor air quality reduces cognitive function and worker productivity by 6 to 9 percent. In a building with 20 employees, that is the equivalent of losing one to two full-time workers to reduced output every single day. For property managers and business owners in Rochester, this is not an abstract concern — it is a cost that shows up in sick days, tenant complaints, and turnover.
Commercial HVAC systems move significantly more air than residential units, and they accumulate contaminants faster. Dust, mold spores, bacteria, and allergens build up inside ductwork and get recirculated through every room in the building every time the system runs. In multi-tenant buildings, what enters the system in one unit can end up in another. In restaurants and food service environments, grease residue and cooking particulates add another layer of buildup that residential systems never encounter.
Clean ductwork also has a measurable impact on your bottom line. The U.S. Department of Energy estimates that dirty HVAC components can increase energy consumption by 25 to 40 percent. For commercial systems running 10 to 14 hours a day, that inefficiency adds up quickly on monthly utility bills. Regular duct cleaning helps your system maintain proper airflow, reduces strain on blower motors and compressors, and can extend the life of your HVAC equipment.
Beyond efficiency and productivity, there are regulatory considerations. OSHA, ASHRAE, and local building codes increasingly address indoor air quality standards for commercial spaces. Maintaining clean ductwork is one of the most straightforward steps a property manager or facility owner can take to stay ahead of compliance requirements and demonstrate a commitment to occupant health and safety.
Commercial Clients We Serve

Offices & Professional Buildings
From single-suite professional offices to multi-floor corporate spaces, we clean the duct systems that keep your team comfortable and productive. Clean air means fewer sick days and a better work environment.
Retail Spaces
Retail environments see high foot traffic and constant door openings, which introduce dust, pollen, and outdoor pollutants into your HVAC system. We help keep your store's air clean and your customers comfortable.
Apartment Complexes
We work with property managers throughout Rochester to maintain air quality across entire apartment buildings. Whether you need individual units cleaned during tenant turnover or a building-wide service, we handle the logistics.
Restaurants & Food Service
Kitchen environments push grease, smoke, and food particulates through your duct system constantly. Regular cleaning helps maintain a healthier environment for staff and diners, and supports health and safety compliance.
Medical & Dental Offices
Healthcare environments have heightened air quality requirements. We understand the sensitivity of clinical settings and work carefully to ensure your ductwork supports the clean environment your patients and staff expect.
Churches & Community Buildings
Large gathering spaces with variable occupancy need HVAC systems that can handle the load. We clean ductwork in churches, community centers, and event spaces so your air stays clean regardless of how many people are in the room.
Our Commercial Duct Cleaning Process
Every commercial job is customized to your building, your system, and your schedule.
Initial Assessment
Every commercial job begins with a thorough assessment of your building's HVAC system and ductwork layout. We evaluate the size and type of your system, identify any areas of concern, and use camera equipment to document the current condition of your ducts. This gives us — and you — a clear picture of what needs attention before any work begins.
Custom Cleaning Plan
No two commercial buildings are the same. We develop a cleaning plan tailored to your building's size, system configuration, and operational schedule. This includes identifying the most efficient sequence for cleaning, any access considerations, and a timeline that accounts for your business hours and occupancy patterns.
Professional Cleaning
Our technicians clean your ductwork using commercial-grade Rotobrush equipment — a rotating brush system paired with a high-performance HEPA-filtered vacuum. The brush physically scrubs the interior surfaces of your ducts while the vacuum captures and removes all loosened contaminants. This is not a basic vacuum-and-blow approach. The Rotobrush system removes buildup that other methods leave behind.
Post-Cleaning Verification
After cleaning, we conduct a full post-cleaning inspection to verify that all sections of your ductwork are clean and that airflow is restored to proper levels. We document the results so you have a record for your maintenance files and can see the before-and-after difference. If anything does not meet our standard, we address it before we leave.
Flexible Scheduling That Works Around Your Business
We understand that commercial duct cleaning needs to happen without disrupting your operations. That is why we offer evening and weekend scheduling for businesses that cannot afford downtime during regular hours. Whether you run a 9-to-5 office, a restaurant with evening service, or a medical practice with a packed weekday schedule, we will find a window that works.
For property managers overseeing multiple units or buildings, we coordinate directly with your maintenance team to plan the work in phases. We can clean individual sections, floors, or units on a rolling schedule so your tenants and occupants experience minimal disruption. Our goal is to get the job done thoroughly and efficiently, on a timeline that makes sense for your building — not ours.
Frequently Asked Questions
Common questions about commercial duct cleaning in Rochester, MN.
Commercial duct cleaning involves larger, more complex HVAC systems with longer duct runs, more branches, and higher air volume than residential systems. The equipment, approach, and time required are all scaled up accordingly. Commercial buildings also accumulate different types of contaminants depending on their use -- offices collect dust and allergens, restaurants accumulate grease and cooking particulates, and medical facilities require extra attention to air purity. We assess each commercial building individually and tailor our cleaning approach to the specific system and environment.
Most commercial buildings should have their ductwork cleaned every 3 to 5 years, though some environments require more frequent attention. Restaurants, medical offices, and buildings with high foot traffic or manufacturing processes may benefit from cleaning every 1 to 2 years. The National Air Duct Cleaners Association (NADCA) recommends regular inspections to determine the right schedule for your specific building. We offer free inspections so you can see the current condition of your ducts and make an informed decision.
In most cases, no. We can clean ductwork in sections while other areas of the building remain occupied and operational. The Rotobrush system is thorough but contained -- the HEPA-filtered vacuum captures contaminants at the source rather than releasing them into the air. For smaller offices or sensitive environments like medical facilities, we typically recommend scheduling the work outside of business hours as a precaution. We will advise you on the best approach during the initial assessment.
Yes. We offer evening and weekend scheduling specifically for commercial clients who need cleaning done outside their operating hours. This is one of the most common requests we receive from Rochester-area businesses, and we are fully set up to accommodate it. Let us know your preferred timeframe when you request your estimate, and we will build the schedule around your needs.
The duration depends on the size of the building, the complexity of the HVAC system, and the condition of the ductwork. A small office suite might take half a day, while a larger commercial building or multi-unit apartment complex could take one to several days. We provide a detailed time estimate as part of your custom cleaning plan so you know exactly what to expect. For larger jobs, we can phase the work to minimize impact on your operations.
Yes. We work with property managers across Rochester and Southeast Minnesota to clean ductwork in apartment buildings of all sizes.
