Whether at work or at home,
we depend on heating, air conditioning,
and refrigeration mechanics and installers,
called HVACR technicians,
to keep indoor air clean and comfortable
in all seasons.
HVACR technicians install electrical wiring
and connect fuel and water supply lines
to create climate control systems.
They also connect systems to air ducts,
and install controls for customers
to set temperature and humidity levels.
Some HVACR technicians specialize
in areas such as commercial refrigeration
or solar panels.
Following government regulations
is critical for installation and repairs,
including proper handling and disposal of fluids
and pressurized gases,
and recycling or conservation of refrigerants.
HVACR technicians work, at times,
in thorny conditions:
they have one of the highest rates of injuries
due to electrical shock, burns, muscle strains,
and injuries from heavy equipment.
They often work in cramped spaces,
sometimes in high heat or deep cold.
Most technicians
work for construction contractors
on systems in homes, schools, hospitals,
stores, or office buildings.
Working full time is typical,
with occasional evening or weekend shifts.
During peak seasons,
they often work overtime or irregular hours.
As systems become increasingly complex,
employers generally prefer applicants
with a certificate or related associate’s degree,
or those who have completed
an apprenticeship.
Workers may need to pass
a background check.
Some locations require HVACR technicians
to be licensed.
