HEI originated with a focus on providing mechanical services for K–12 education facilities. Over the years we have expanded our engineering services but our established reputation in the education sector has continued and allowed us to work with more than half of the school districts in Minnesota. We understand the issues and concerns that education facilities face today, and we have experienced staff who consistently provide high–value solutions. Our services include design and commissioning for system upgrades, facility assessments, renovations, and new construction.
