Great Lakes Geothermal

Great Lakes Geothermal is a specialized geothermal drilling and ground loop contractor serving Northern Illinois, including the Chicago metropolitan area. Unlike general HVAC contractors, Great Lakes Geothermal focuses exclusively on the external, below-ground components of geothermal systems, bringing deep expertise in drilling, trenching, and ground loop design and installation. The company's specialized services include vertical drilling for borehole heat exchangers, horizontal trenching for shallow loop systems, thermal conductivity testing to characterize site-specific soil and rock thermal properties, and the design and construction of well fields for large commercial and institutional geothermal projects. Their IGSHPA Accredited Installers bring the highest level of professional certification to every project. Thermal conductivity testing is a critical service that Great Lakes Geothermal provides to ensure accurate ground loop sizing. By measuring the actual thermal properties of the soil and rock at a specific site, they can design ground loops that are precisely sized for the project's heating and cooling loads, avoiding the over- or under-sizing that can compromise system performance and efficiency. Great Lakes Geothermal's well field design and build capabilities make them a valuable partner for large commercial, institutional, and industrial geothermal projects that require multiple boreholes or complex loop configurations. Their engineering expertise and specialized drilling equipment allow them to tackle projects of any scale, from single-family residential installations to large commercial well fields. Serving Cook, Kane, Will, DuPage, and Lake counties throughout the Chicago metropolitan area, Great Lakes Geothermal is a trusted drilling and ground loop partner for geothermal contractors, engineers, and building owners throughout Northern Illinois.
