Safety First – Upholding the Highest Standards
At AMS, we recognize that operational excellence begins with uncompromising safety.
We maintain all required state and federal HVAC certifications and strictly adhere to OSHA requirements across every commercial job site. Through technician training, routine toolbox talks, and the elite safety standards of Pipefitters Union Local 537, we have a culture where risk mitigation is proactive rather than reactive. With the implementation of our advanced 2026 safety program, we are reinforcing our commitment to protecting our workforce, securing your facility, and safeguarding your capital investments.
Our Culture
Shared Expertise and Growth
Our culture is pretty simple: we show up for each other, do the job right, and never stop learning.
We don’t operate in silos. Our office and field teams stay locked in and share information constantly, which keeps our projects running smooth and keeps mistakes off the job site.
A huge part of who we are comes down to our Local 537 workforce. We don’t just hire skill, we build it! We invest heavily in ongoing training so our crews stay the sharpest in the trade. At the end of the day, AMS is built on teamwork, smart solutions, and pride in the work.
Our Commitment
What drives our operations at AMS is the impact of the facilities we protect. We aren’t just maintaining mechanical systems, we are architecting the reliability that allows cutting-edge research labs, mission-critical data centers, and higher education institutions to function without interruption.
“I take immense pride in our team from Local 537. Their dedication to safety and quality ensures that we don’t just meet the expectations of our clients, we set the industry standard for operational continuity.”- Dan LaBlanc – Vice President
