United Mechanical’s Large Tonnage Expertise

We employ the best expertise in the business when it comes to large tonnage cooling equipment. Our group of large tonnage mechanics are among the most respected in the nation, recognized as leading technical experts in their field. Whether it be a centrifugal, screw, or large chassis recip, including all magnetic bearing compressors, we are one of the few service providers capable of servicing all major OEM brands with our own in-house personnel.

We know you need rapid response service, 24/7/365. Instead of waiting days or even weeks for an OEM technician to make it to your site, our team stands ready to respond within hours to your demand service calls. The other added benefit of using United Mechanical is that unlike an OEM technician that may just work on one type or brand of equipment, we can handle your entire mechanical system. This results in single source accountability, faster response and repair, and quite often, substantially lower costs.
