Refrigeration

Workers in this field install and maintain the heating and air-conditioning systems that control the temperature, humidity and total air quality in residential, commercial, industrial and other buildings by precisely following blueprints, design specifications and manufacturers’ instructions.

They need knowledge of electrical components and systems since heating, air-conditioning and refrigeration systems consist of many mechanical, electrical and electronic components such as motors, compressors, pumps, fans, thermostats and switches.

In refrigeration, technicians work with a variety of precision measuring tools to manipulate conditions such as refrigerant pressures and air flow in duct systems. Voltmeters, pressure gauges, manometers and other testing devices are used in analyzing system performance. When servicing equipment, they must use extreme care to conserve, recover and recycle the chlorofluorcarbon (CFC) refrigerants used in the refrigeration and air-conditioning systems.

Traits & Talents
For a successful career in refrigeration, you should have an aptitude for electronics and a curiosity about how things work. You must be courteous and tactful, and have good communication and listening skills for dealing with customers’ needs and refrigeration problems. Good math, computer and problem-solving skills are important assets for working in this profession. It is also necessary to be physically fit as lifting and moving heavy equipment is sometimes required.

Refrigeration workers apply their trade in homes, supermarkets, hospitals, office buildings, factories – anywhere that you would find climate control equipment. They are employed by heating and cooling contractors, fuel oil dealers, refrigeration and air-conditioning service and repair shops or self-employed as sub-contractors. Their skills are in demand in all sectors, and they are learning constantly since the technology involved is always changing. They often work indoors in cramped and awkward positions or at great heights on large commercial buildings.
