Sophisticated refrigeration and climate control systems require technologically skilled technicians.

HVAC/R  Overview

          Commercial and industrial climate control systems - such as freezers and coolers in a supermarket or the heating, ventilation and air conditioning (HVAC) in a large office building - are technologically advanced machines that require constant calibration and maintenance. Not only is it essential that this equipment keep working, but the high cost of energy requires that they operate as efficiently as possible.

          The professionals who service these large refrigeration and climate control systems are the HVAC/R technicians who are specialized members of the pipe trades.

          HVAC/R service technicians repair and maintain the refrigeration systems in supermarkets, restaurants and convenience stores, as well as the industrial heating, ventilation and air conditioning systems in office buildings, manufacturing facilities, hospitals and other large structure. They also install and maintain the special climate systems for computer rooms, where a constant cool temperature and humidity control is necessary to keep these sophisticated machines running smoothly.

          Most of an HVAC/R technician's work is spent repairing and maintaining systems. They do not install or repair the ducts that circulate the air coming from heating and air conditioning equipment. The systems they work on are becoming more technically involved at a rapid pace. Advanced electrical circuits and state-of-the-art software programs control the systems of pipes, valves, furnaces and mechanical compressors that circulate the liquids and gases used for cooling and heating. For this reason, a growing portion of a technician's time is spent on computers, which control the latest climate control systems.

          Electric circuitry and physics also are a routine part of a technician's job. HVAC/R technicians are experts on how an interior climate is affected by external forces. They understand the dynamics of air flow and how it can be used to help systems work more efficiently to conserve energy costs. For instance, vents that open and close according to the outside temperature can reduce the workload on air conditioners. Using their skilled precision in calibrating the equipment that operate these vent systems, HVAC/R technicians can help an office building, retail store or manufacturer save thousands of dollars per month on it's electric bill.

          Ever-evolving technology constantly challenges HVAC and refrigeration technicians to hone their knowledge and skills, but it ensures that they will always be in high demand.
