Environmental Systems Corporation of Huntsville was incorporated in 1976 as a woman owned business and has grown from a commercial HVAC service company to a full service Engineering, Construction and Services firm providing a broad range of services to commercial and industrial clients throughout the Southeast.

Our growth has been built on a foundation of professional quality, ethical business practices, long-term client satisfaction and a drive for innovative technologies to serve our clients better.

The new engineering division is the firm of Paul Smith & Associates, which merged with Environmental Systems in 2003. The combined resources of Environmental Systems Corporation now represent over 50 years of experience in the HVAC industry.
