The "GT" in GT Mechanical

Greg Uher & Tim Uher

GT Mechanical, Inc., founded in 1991 by Local 597 Pipe Fitter Tim Uher, is a family-owned enterprise with a reputation for providing quality HVAC service, products and system solutions to the Commercial, Institutional and Industrial markets of the Chicagoland and Northwest Indiana areas.

Tim’s vision for GT Mechanical was to become a full service HVAC company. In 2001, with GT Mechanical, Inc. running full force, Tim established a second company, GT Mechanical Projects & Design, Inc. This division of GT was established to specialize in the plan & spec and design/build process for HVAC projects while GT Mechanical, Inc. continued to focus its expertise on the Service and Maintenance portion of the business.

It was in 2001 that Tim’s brother Greg Uher joined the GT Mechanical team to head up this new corporation and allowed Tim to remain focused on the Service & Maintenance Division. With the creation of the second company, Tim Uher was able to see his vision for his company, started 10 years earlier, become a reality. GT Mechanical had now evolved into a full service HVAC company by having the ability to offer customers a more complete HVAC package from design to commissioning to servicing/maintaining an entire HVAC system.

Today, the professional team of GT Mechanical continues to be led by founder Tim Uher and brother and co-owner, Greg Uher. Tim Uher has over 20 years experience in installations and trouble shooting HVAC Systems and Greg Uher matches those 20 plus years of experience in HVAC engineering and commissioning. Both of these individuals bring their vast HVAC knowledge and skills together to resolve some of the most challenging HVAC issues. Tim continues to oversee the direction of the Service & Maintenance Company and is even known to occasionally take an active role in daily service calls to keep in touch with the customers and understand the challenges they face. While overseeing the daily activities of the Projects & Design Division, Greg continues to apply his numerous years of engineering experience to design an HVAC system that meets the specific needs of our customers no matter how simple or complex.

The remainder of the GT Team is comprised of:

Engineers who are well known in the Mechanical Industry for providing solutions and energy-efficient HVAC systems
