What is the job outlook?
Maryland stationary engineers and boiler operators earn an average annual salary of $54,500. Growth for these jobs is slightly slower than average at 5 percent; however, continuing commercial and industrial development will increase the amount of equipment that needs to be operated and maintained. Although automated systems and computerized controls are making newly installed equipment more efficient, experienced workers will be needed to maintain and repair these complex systems.

AACC offers two noncredit courses to prepare for the Maryland stationary engineers exam, grades 1 through 5, given by the state of Maryland. Each course can be completed in less than three months and will cover the basics of low-pressure and high-pressure boilers, computer-assisted combustion controls; hydronic heating systems; basic electrical, refrigeration and HVAC systems; fire prevention and safety; and the American Society of Mechanical Engineers code requirements. Total Hours: 72
