Heating, Air Conditioning, and Refrigeration Mechanics and Installers
Working Conditions
Heating, air conditioning, and refrigeration mechanics and installers held about 292,000 jobs in 2014, of which 63 percent were in the plumbing, heating, and air conditioning contractors industry. About 1 in 10 were self-employed in 2014.
HVACR technicians work mostly in homes, schools, stores, hospitals, office buildings, or factories. Some technicians are assigned to specific jobsites at the beginning of each day. Others travel to several different locations, making service calls.
Although most technicians work indoors, some may have to work on outdoor heat exchangers, even in bad weather. Technicians often work in awkward or cramped spaces, and some work in buildings that are uncomfortable because the air conditioning or heating system is not working properly.
Injuries and Illnesses
HVACR technicians have one of the highest rates of injuries and illnesses of all occupations. Potential hazards include electrical shock, burns, muscle strains, and injuries from handling heavy equipment.
Appropriate safety equipment is necessary in handling refrigerants, because they are hazardous and contact can cause skin damage, frostbite, or blindness. When working in tight spaces, inhalation of refrigerants is also a risk. Several refrigerants are highly flammable and require additional care.
Work Schedules
The vast majority of HVACR technicians work full time, with occasional evening or weekend shifts. During peak heating and cooling seasons, they often work overtime or irregular hours. Although most technicians are employed by construction contractors, about 1 in 10 are self-employed workers who have the ability to set their own schedules.
Technicians who service refrigeration, heating, and air conditioning equipment generally have stable employment throughout the year, particularly because a growing number of manufacturers and contractors now provide or even require year-round service contracts.
