John F. Berzanskis Sr.


Vision Come to Fruition

AMS Industries history begins with John Berzanskis Sr., a hard-working man with humble beginnings, originally founded AMS back in 1963 under the name of Antarctic Refrigeration, Inc. John began his refrigeration company as a sole proprietor working out of a former gas station facility in Chicago, Illinois. His simple premise was to work hard and to provide honest, reliable service to the refrigeration industry.

Erasing Parameters

With his father’s retirement four years prior, it was in 1982 that John F. Berzanskis Jr. would take the reins of what was AMS Mechanical Systems Inc., and become president and owner while always holding fast to his father’s philosophy to provide excellent service with a strengthened foundation for quality and integrity.

AMS Industries has a history marked by a commitment to excellence, now leading with over 500 dedicated staff members. Our office and support staff incorporate an array of highly qualified, experienced employees including graduate mechanical engineers, professional engineers, piping and sheet metal designers, experienced estimators and project managers along with trained administrative assistants and accounting personnel. Field operations consist of superintendents, general foremen, field engineers, safety personnel, journeymen, and apprentices for each signatory trade.

Ben is continuing on our course of action of building a better, stronger and more durable company for future generations, protecting the AMS brand, meeting our commitments to clients, developing our people, and helping improve communities.
