The Refrigeration Service Engineers Society (RSES) has announced the names of members who were awarded RSES Certificate Member (CM) status in January, including a member of the Houston Chapter, Stephen L. McWilliams.

In order to become a CM, a RSES member must first pass an examination that tests the knowledge required to install and service refrigeration and air conditioning equipment. According to the society, CM-level members are recognized industry-wide as having achieved a superior level of HVACR knowledge. The exam is based on both theory and practical applications.
