The maintenance and installation of climate control refrigeration equipment in residential and commercial buildings is the responsibility of a refrigeration mechanic. Building cooling, restaurant kitchens, and other large-scale climate control devices all use refrigeration systems. Because the complexity of these systems necessitates specialized knowledge in order to install and repair them, refrigeration mechanics are hired to replace component parts, construct new units, and perform routine maintenance on refrigeration machines. Companies that use refrigeration devices may hire mechanics full-time, or they may work for a company that fulfills service contracts and responds to repair calls on an as-needed basis.
Because there are so many different types of refrigeration machines, a refrigeration mechanic is typically well-versed in both basic and complex system layouts. Working on cooling systems in buildings may also necessitate the removal and replacement of ceiling and ductwork. To both install new systems and repair and replace component parts, a refrigeration mechanic will interpret and use blueprints and schematics.
A refrigeration mechanic frequently employs diagnostic equipment to identify and resolve system issues. Refrigeration mechanics may need to use special tools and electronic devices to install and repair cooling machines because they use compressors and motors that must be maintained on a regular basis. A refrigeration mechanic can choose to specialize in either mechanical or electrical climate equipment, or gain further specialization in a specific system type. Refrigeration mechanics can work as self-employed independent contractors if they are not employed by a company that has climate control equipment or by a repair service.
Refrigeration mechanics may be required to have and maintain a regional authority-issued license, depending on local ordinances and regulations. Most mechanics learn on the job, and they may be required to renew their license on a regular basis to stay current. Most mechanics have a high school diploma, and some have additional training from a trade school or community college.
Because there may be emergency issues and repairs, a refrigeration mechanic’s work week may be unusual, requiring work on weekends and outside of normal business hours. Installation and repair work may also be done after business hours to avoid disrupting normal work flow and customer experiences. Refrigeration mechanics typically work on machines and systems on site, rather than at a desk or in an office. Because electrical systems and moving parts in machines are frequently worked on, the nature of the work entails some risks, and extreme safety precautions must be taken at all times. In response to the work environment, a refrigeration mechanic should wear safety equipment such as hard hats, gloves, and protective eyewear on a daily basis.
