Air Conditioning Technology
Nature of Work
Heating and air conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings. By providing a climate-controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items. Heating, air conditioning, and refrigeration mechanics and installers install, maintain, and repair such systems.
Heating, air conditioning, and refrigeration systems consist of many mechanical, electrical, and electronic components such as motors, compressors, pumps, fans, ducts, pipes, thermostats, and switches. In central-forced air heating systems, for example, a furnace heats air, which is then distributed through a system of metal or fiberglass ducts. Technicians maintain, diagnose, and correct problems throughout the entire system. To do this, they adjust system controls to recommended settings and test the performance of the system using special tools and test equipment.
Technicians follow blueprints or other specifications to install oil, gas, electric, solid-fuel, and multiple-fuel heating systems and air conditioning systems. After putting the equipment in place, they install fuel and water supply lines, air ducts and vents, pumps, and other components. They may connect electrical wiring and controls and check the unit for proper operation. To ensure the proper functioning of the system, furnace installers often use combustion test equipment, such as carbon dioxide testers, carbon monoxide testers, combustion analyzers, and oxygen testers. These tests ensure that the system will operate safely and at peak efficiency.
High school students interested in some initial training for this industry should take courses in shop math, mechanical drawing, applied physics and chemistry, electronics, blueprint reading, and computer applications. Some knowledge of plumbing or electrical work and a basic understanding of electronics are beneficial for a heating, air conditioning, and refrigeration technician.
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 21 percent nationally from 2012 through 2022.
