Founded in 1976, Environmental Systems Corporation has provided the best in HVAC services to commercial and industrial clients in the North Alabama and Southern Tennessee area. The company was originally founded as a small two-person firm primarily aimed at maintenance and piping systems to deal with Environmental Test Chambers on Redstone Arsenal. Environmental Systems Corporation has expanded greatly in the last 37 years and the focus of the company has changed as well. While Environmental Systems Corporation still provides services dealing with the original focus of Environmental Test Chambers, the primary focus for the firm has changed over the years. Today, the firm provides turnkey HVAC systems to the defense contracting industry (and other industries that keep Huntsville and North Alabama in business), complete mechanical engineering and design services, building commissioning, energy management, building automation, budgeting services, maintenance solutions, and more. Environmental Systems Corporation is now transitioning to a second generation of ownership.
