RSES CM Exam Becomes Journeyman Credential for
MI-based Air Doctors Heating and Cooling Contracting Business

Arlington Heights, Ill. (June 8, 2021) – RSES is honored to have its distinguished Certificate Member (CM) exam selected as the “top out/journeyman credential” for the MI-based Air Doctors Heating and Cooling contracting business’s four-year (8,000-hour) training program.

AirDoctors_Logo_White“It is exciting that Air Doctors decided to use the CM exam as their top out/journeyman credential,” says Mike Ralston, CM, RSES International President. “Having taken the exam myself, I know that these journeymen will be highly educated members of the workforce. These technicians are the ones who will properly take care of their customers, because they have the knowledge to do the job correctly.”

Good help continues to be difficult to find today, and this is especially true of the HVACR business. Many contracting business owners are complaining about the ever-difficult task of finding qualified help. Skilled trade occupations in general are having issues with an insufficient work force, and HVACR is at the front of the line. The pandemic has compounded the problem. People are more concerned with their comfort and indoor air quality now more than ever. As a result of the work shortage, the customer or end-user suffers. The customer or end-user experiences long lead times for service and repair activities, and higher prices.

RSES Regions 8 & 11 Director, Brynn Cooksey, CMS, RCT is the owner of the company and developer of the training program. “If you can’t find them, grow them,” says Cooksey when commenting on the HVACR technician shortage.

Air Doctors Heating and Cooling decided to take the worker shortage into their own hands by approaching the Michigan Department of Labor and registering their internal training program as a registered apprenticeship. Having a registered apprenticeship, opens up doors to access candidates who may have been hard to reach without the Department of Labor’s help.

Cooksey, who also serves on the RSES Educational & Examining Board, is extremely familiar with the SM, CM, CMS series of exams. “The CM exam is one of the most challenging and compressive test in the HVACR industry,” says Cooksey. “An individual with this credential has proven their competency in the industry.”

Originated in 1935, the CM designation means that the person earning this distinction of membership has passed a rigorous exam that tests 18 categories of knowledge required in the installation and service of HVACR equipment. Traditionally only available to Members, RSES is opening the door to technicians passing the exam first and becoming a Member as a result.

“Anyone completing an apprenticeship program who is able to pass this exam earns their RSES membership in my book,” says RSES Executive Vice President Lori Schiavo. “Traditionally, this exam has a 30% pass rate, so I am eager to call these ‘students’ Members upon passing! I am excited to work with Air Doctors and Brynn and to offer the exam as a part of their program.”  

This relationship is yet another example of how RSES is working with the industry to help grow a more skilled workforce.
