                                                In 1972, Mike Hendricks, Sr. started to create his own business. Trained as an aeronautical engineer, Mike had specialized in designing equipment that involved air flow, pressures, vacuums, and electronic controls. That experience with complex air flow systems transferred easily to the HVAC industry.
Mike wanted to create a straightforward, honest business that would succeed on the basis of his own integrity. Most of his early customers were friends and collegues. In 1975, as his customer list grew, he left the corporate world to devote his full attention to the endeavor.
Shortly after that, Richard Dean joined him as a partner. Richard had graduated from college with a degree in information systems and business processes. Together, the two launched Environmental Systems Associates, operating out of the trunk of Mike's car.
commitment to quality and integrity grew their fledgling business quickly. In 1983, Mike's son, Michael Hendricks joined the team as Service Manager.
