Mechanics do routine maintenance and repair work to keep installed furnaces in order. They do maintenance work. This involves replacing filters, vacuum-cleaning vents, ducts, and other parts of the system. Refrigeration systems are used for many purposes. They make it possible to store and transport medicine, food, and other items that must be kept cool.
Mechanics follow blueprints and instructions.
These blueprints are used to install motors, compressors, condensing units, evaporators, and other parts. They connect the equipment to ducts, refrigerant lines, and power sources. Then they charge the system with refrigerant. Mechanics diagnose problems when systems break down. They make repairs, test parts, inspect systems, and overhaul compressors.
