My name is Stephen Szulhan, Facilities Manager at SUMA Federal Credit Union, the third largest credit union in Westchester County. I have worked with Ryan and John McCormick of ThermoDynamics Corp. for nearly two years and I am extremely pleased with their service and professionalism. We do regular P/M work as well as upgrades and and improvements to our current systems. One example of an upgrade was the installation of a new 2 ton Mitsubishi “P” series system for our computer room. It was the perfect solution for our needs. I really enjoy working with Ryan and John and their “A” team service staff.
