Green Energy Solutions U.S., Inc. (GES) is a privately - held Illinois company that provides geothermal heating and cooling systems from its location in Elgin, Illinois. While created as startup company, GES serves as an extension of Master Hand Contractors, Inc., Masterhaus, Inc., and Purcon LTD, which have been providing ground-up construction services for over twenty years. The goal of GES is to provide alternative energy installation services that represent the latest advancements in patented, highest quality "green" technology at the most competitive price.

GES is positioning itself to meet a growing level of demand for geothermal systems in the area with cutting edge technology. The green benefits of GES's systems, when compared to traditional systems, go beyond removing the need for fossil fuel; the systems are significantly more environmentally friendly with regard to air pollution, using only minimal amounts of electricity. The environmental impact of every new small (residential) system installation is comparable with eliminating the yearly carbon imprint of tree cars.
