Heating & Cooling in Yale, Michigan

Founded in 2008 by John and Diane Schlorke, Geo Tech is a family-owned company located in Yale, Michigan that has nearly doubled its customer base with each successive year of operation. Originally focused on geothermal, we have expanded our scope to include the installation and repair of other types of heating and cooling systems and water heaters as well. In the Beginning, John Schlorke ran his company out of his truck with nothing but a set of tools. Diane did the scheduling and took care of the advertising and marketing needed to keep the new business afloat. A loan from John’s father helped them get their first dependable work van, and while John was initially reluctant to accept the loan, it has proven to be a vital part of the growth of Geo Tech—and John naturally followed his instinct to repay his father before paying himself. With the loan paid off, they hit the ground running, building their shop in 2009. Growing and expanding every year, Geo Tech has built a new office building to add to their homegrown business. In 2017 they added this beautiful addition to make it more organized in the office, and for each office person to have their own space to create quotes, scheduling, and to have a portfolio for each of our customers. Today they serve St. Clair County, Lapeer County, Sanilac County, and surrounding areas with five employees: John Schlorke, Diane Schlorke, Carter Harway, Nate Fantin, and Stephinie Hartway part time as she is going to college. They have a ductwork fabrication shop, two vans, a truck, a box truck and two trailers, all ready to meet your needs!
