AMS Industries, Inc.

AMS Industries, Inc. has operated as an employee-owned mechanical contractor in Woodridge, Illinois since 1963, when founder John F. Berzanskis Sr. established the company. Now entering its seventh decade of continuous operation, AMS Industries holds a 4.5-star rating compiled across 52 client reviews, a figure that reflects consistent performance across both residential service calls and large-scale industrial projects. The company maintains round-the-clock availability, offering around-the-clock emergency service seven days per week, including holidays. Serving the greater Woodridge region and surrounding DuPage County communities, this MEP+ contractor handles comprehensive mechanical, electrical, and plumbing scope, positioning itself as a single-source solution for property owners managing complex building systems.

What distinguishes AMS Industries from regional competitors is the breadth of its integrated project delivery model. The firm operates an in-house engineering division employing VDC/BIM technology, enabling prefabrication of mechanical assemblies before they reach the jobsite, a methodological edge that accelerates completion timelines while reducing field labor costs. Their portfolio extends beyond conventional commercial work into industrial refrigeration and food process piping, specialized verticals requiring code compliance expertise and equipment knowledge that typical HVAC contractors lack. The company maintains its commitment to zero safety-related incidents across all field operations, a metric tracked through internal EMR reporting, underscoring organizational discipline in high-hazard industrial environments.

Customer reviews highlight specific technicians who resolved problems other contractors could not diagnose. Dr. Ammonia provided phone guidance to a homeowner troubleshooting a personal unit, walking the caller through troubleshooting steps without charging for the consultation. Matt addressed a year-long heating system failure at a commercial retail location along Michigan Avenue, identifying the root cause and completing repairs within a single business day, allowing the client to remain open throughout the service call. These accounts underscore a service culture where technical competence and communication replace transactional customer interactions.
