Environmental Systems Associates

In 1972, Mike Hendricks, Sr., set out to create his own business. Trained as an aeronautical engineer, Mike specialized in designing equipment involving airflow, pressures, vacuums and electronic controls. That experience with complex airflow systems transferred easily to the HVAC industry. Mike wanted to create a straightforward, honest business that would succeed on the basis of his own skills and integrity. Most of his early customers were friends and colleagues. In 1973, as his customer list grew, he left the corporate world to devote his full attention to the endeavor.In late 1973, he hired his first employee, Richard Dean, who was working his way through college at the University of Maryland. Over the next few years, Richard received his degree in information systems management, and they formed the partnership that is Environmental Systems Associates.
