 When it comes to commercial and industrial HVAC, plumbing, and refrigeration, they really know their stuff. What's more, they really know their individual customers. And here's why. When you are a customer of Current Mechanical Service Group, our goal is to send the same technician to your facility every time you call for maintenance or service. You'll get to know that person on a first-name basis. As we learn more about your facility, service and maintenance becomes easier and faster.
