The “GT” in GT Mechanical

Tim Uher & Greg Uher

For over 30 years, GT Mechanical has been a family-owned enterprise with an outstanding reputation in the Heating, Ventilation, and Air Conditioning Industry in the Chicagoland and Northwest Indiana areas. 

How did it all start?

GT MECHANICAL, INC. was first founded in 1991 by local 597 pipefitter Tim Uher. For 10 years, Tim built an HVAC company that provided quality HVAC service, products, and system solutions to the commercial, institutional, and industrial markets of the Chicagoland and Northwest Indiana areas. However, Tim sought a bigger vision for GT; he envisioned this growing into 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 and 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. At this point, Tim’s brother - Greg Uher - joined the GT Mechanical team to head up this new corporation while Tim remained focused on the Service & Maintenance Division. With the creation of the second company, Tim Uher was able to see his vision for the company to become a reality.

GT Mechanical has 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 30 years of experience in installations and troubleshooting HVAC Systems, and Greg Uher matches those 30 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 HVAC systems that meet the unique needs of our customers no matter how simple or complex.
