Indoor Air Quality

Commercial & Industrial Buildings

Commercial and Industrial building owners understand that the best buildings are an asset. Owner-operated businesses, industrial warehouse facilities, commercial or residential property managers, and everything in between: the indoor air quality in each building has a direct impact on profitability.

We use the latest technology to test the indoor air quality of your facility. Our fully trained, experienced experts are certified to perform your IAQ testing and have the know-how to diagnose and treat any HVAC issues that may be causing your IAQ to suffer. Your building needs to be able to breathe to ensure that fresh air comes in and dirty air goes out. If your facility isn’t properly ventilated, high levels of odors, moisture, dust, gases, carbon dioxide, and other pollutants could be present in your air.

We’re focused on providing you air quality services as well as answering your mechanical services and equipment needs. With our team of experienced technicians, you can establish and maintain proper environmental systems operations.

Sick Building Syndrome

We understand that indoor air quality is extremely important. In fact, poor indoor air quality can result in sick building syndrome (SBS), a syndrome that consists of various nonspecific symptoms that occur in the occupants of a building. A decrease in productivity and an increase in sickness absenteeism are often the result of SBS. Exposure to indoor air pollutants may result in various health effects; many are short-term with medical treatment and proper mitigation of exposure.


Symptoms of SBS Include:
Eye, nose, & throat irritation
Dry or itching skin
Dry cough
Difficulty concentrating
Sensitivity to odors
Flu-like symptoms
Personality changes
Increased incidence of asthma & asthma attacks



Our in-depth evaluation process is designed to identify current and potential problem areas. Air quality testing can unearth a variety of pollutants which, left unmitigated, can evolve into much more significant problems.

With access to a variety of equipment manufacturers, as well as the largest, most experienced crew of HVAC contractors in Sioux City, we know how to design or improve a system to achieve your goals, while operating within your budget.
We offer a wide range of indoor air quality solutions and products to address your IAQ improvement needs, and to prevent future air quality issues.

We strive to provide a system customized to address your needs, achieve your goals, and stay within your budget.
