Our Commitment to Quality

Quality Air Service, Inc. was founded in 1977 by Charles E. Stephens to provide high quality products and services for HVAC systems and, in particular, areas requiring high efficiency filtration.  In addition, we specialize in providing critical air flow control systems and exhaust systems especially designed for laboratories.

Our customer list includes pharmaceutical, bio-medical, research and development, laboratory, educational, nuclear, governmental, international, hospital and other medical facilities.

Our corporate offices are located in Kalamazoo, Michigan, with the majority of our service ranging out for an approximate 100-mile radius.

We specialize in representing only a limited number of elite manufacturers of high caliber air filtration, laboratory control and air handling equipment.  Our service support team completes our corporate goal to ensure satisfaction during installation, during start-up and for many years after the initial installation is commissioned and put into service.

High standards and commitment to quality have led to long-standing relationships with the majority of our customers.
