Stationary engineers are in charge of the systems that keep buildings comfortable. They take care of the heating, air-conditioning, and ventilation systems. They may also take care of the mechanical systems. They watch over boilers, refrigeration equipment, and diesel engines. Stationary engineers also check on turbines, generators, pumps, condensers, and compressors.
Engineers start up, regulate, and shut down equipment.
They make sure that it operates as safely and cheaply as possible. To make sure that the equipment is working within its limits, stationary engineers check on meters, gauges, and computerized controls. If needed, they adjust the equipment by hand. Engineers also perform maintenance on the systems. They may lubricate parts, replace filters, and remove corrosion.
