EMS History

Eastern Mechanical Services (EMS) has a proud heritage of heating, air conditioning and plumbing expertise. It all started in Grand Rapids, Michigan, during the days of the Great Depression. John Huizinga ventured out in his pickup truck plumbing houses to feed his young family. This entrepreneur worked hard to start what became a well-established plumbing and heating company called, “Holwerda Huizinga Plumbing and Heating.” Later, John’s company started Associated Mechanical Services (AMS) in Kalamazoo, Michigan, which was run and owned in part by his son, Thomas. During his tenure there, Thomas grew AMS into one of Domestic Engineering’s top 50 companies in the early 1970s — and to this day, they are a major contractor in the mechanical building trades in southwestern Michigan. Then in 1985, Thomas moved to western Connecticut and founded EMS with his own two sons, Ted and John. Ted and John Huizinga now carry the torch of diligence and quality workmanship as modeled by father and grandfather. As part of the old school heritage, these qualities are being instilled and cultivated in EMS employees today. Exemplary Mechanical Service is key to Eastern Mechanical’s Success!
