About Us

CleanAir is knowledgeable and experienced people, coupled with state-of-the-art equipment and technology, all focused on providing our clients with highest value products and services for process and environmental performance. Since 1972, whether for air quality management and emissions measurement, or thermal performance and efficiency determination, or any of our many other products and services, CleanAir delivers the results.

How We Work

First and foremost, we listen to gain a deep understanding of our client’s needs and business objectives and to better leverage our technical knowledge, innovative thinking, and equipment resources. At CleanAir, our aim is to support the growth, profitability, and sustainability goals of our clients by delivering innovative solutions with 10x value.  MORE

Our aim is to provide you with the highest possible value in everything we do. The more we know about your business, your challenges, and your project, the more we can do to ensure a high value outcome. Our goal is to define measurable benefits to our clients on every project and deliver value worth at least 10 times our invoice. This may be wishful thinking but we believe we can make a big difference to you, our client, and your bottom line if we aim high.

“Nobody Gets Hurt.”

CleanAir is committed to this simple and clear vision for the safety and health of our employees and others. We are working hard across CleanAir to maintain a Zero Incident Culture. MORE

Safety is our highest priority and must be part of every decision and operation. We embody the attitude that “all injuries and accidents are preventable” and through the commitment of our leaders and the involvement of our employees, we will continuously improve our safety program and adopt best practices that meet and exceed all Federal, State and Local safety regulations.

Without question, safety is everyone’s responsibility at all levels. We accept personal accountability for our own safety. When we recognize hazards we will intervene and mitigate to ensure the safety of ourselves and others. We all own it.

Everyone at CleanAir is empowered to improve our safety culture through Near Miss Reporting, Job Hazard and Job Safety Analyses, and Safety Meeting participation.

I am personally committed to a safety and health program that will ensure the Safety and Health of everyone.

Our TRIR and EMR have been trending lower for the last five years and are currently 0 and .89 respectively. We will get the safety results that we insist on. Join me in insisting on Zero Incidents.
