Employment
Heating, air conditioning, and refrigeration mechanics and installers work for plumbing, heating, and air conditioning contractors, as well as in a variety of industries throughout the country, reflecting a widespread dependence on climate-control systems. Some work for refrigeration and air conditioning service and repair shops, schools, and stores that sell heating and air conditioning systems. Local governments, the federal government, hospitals, office buildings, and other organizations that operate large air conditioning, refrigeration, or heating systems also employ these workers. Many technicians are self-employed. Employment of heating, air conditioning, and refrigeration mechanics and installers is projected to increase 28 percent nationally during the 2008-2018 decade, much faster than the average for all occupations.
