1
00:00:01.233 --> 00:00:03.599
Whether at work or at home,

2
00:00:03.600 --> 00:00:06.100
we depend on heating, air conditioning,

3
00:00:06.100 --> 00:00:08.633
and refrigeration mechanics and installers,

4
00:00:08.633 --> 00:00:11.199
called HVACR technicians,

5
00:00:11.200 --> 00:00:13.833
to keep indoor air clean and comfortable

6
00:00:13.833 --> 00:00:15.366
in all seasons.

7
00:00:15.366 --> 00:00:19.066
HVACR technicians install electrical wiring

8
00:00:19.066 --> 00:00:21.732
and connect fuel and water supply lines

9
00:00:21.733 --> 00:00:24.499
to create climate control systems.

10
00:00:24.500 --> 00:00:26.800
They also connect systems to air ducts,

11
00:00:26.800 --> 00:00:29.100
and install controls for customers

12
00:00:29.100 --> 00:00:32.133
to set temperature and humidity levels.

13
00:00:32.133 --> 00:00:34.966
Some HVACR technicians specialize

14
00:00:34.966 --> 00:00:37.832
in areas such as commercial refrigeration

15
00:00:37.833 --> 00:00:39.666
or solar panels.

16
00:00:39.666 --> 00:00:41.466
Following government regulations

17
00:00:41.466 --> 00:00:44.566
is critical for installation and repairs,

18
00:00:44.566 --> 00:00:47.399
including proper handling and disposal of fluids

19
00:00:47.400 --> 00:00:49.700
and pressurized gases,

20
00:00:49.700 --> 00:00:53.200
and recycling or conservation of refrigerants.

21
00:00:53.200 --> 00:00:56.400
HVACR technicians work, at times,

22
00:00:56.400 --> 00:00:57.866
in thorny conditions:

23
00:00:57.866 --> 00:01:00.499
they have one of the highest rates of injuries

24
00:01:00.500 --> 00:01:03.433
due to electrical shock, burns, muscle strains,

25
00:01:03.433 --> 00:01:05.899
and injuries from heavy equipment.

26
00:01:05.900 --> 00:01:08.333
They often work in cramped spaces,

27
00:01:08.333 --> 00:01:11.166
sometimes in high heat or deep cold.

28
00:01:11.166 --> 00:01:12.766
Most technicians

29
00:01:12.766 --> 00:01:14.399
work for construction contractors

30
00:01:14.400 --> 00:01:17.700
on systems in homes, schools, hospitals,

31
00:01:17.700 --> 00:01:19.966
stores, or office buildings.

32
00:01:19.966 --> 00:01:21.966
Working full time is typical,

33
00:01:21.966 --> 00:01:24.832
with occasional evening or weekend shifts.

34
00:01:24.833 --> 00:01:26.366
During peak seasons,

35
00:01:26.366 --> 00:01:29.832
they often work overtime or irregular hours.

36
00:01:29.833 --> 00:01:32.599
As systems become increasingly complex,

37
00:01:32.600 --> 00:01:35.100
employers generally prefer applicants

38
00:01:35.100 --> 00:01:38.333
with a certificate or related associate’s degree, 

39
00:01:38.333 --> 00:01:39.799
or those who have completed

40
00:01:39.800 --> 00:01:41.300
an apprenticeship. 

41
00:01:41.300 --> 00:01:42.700
Workers may need to pass

42
00:01:42.700 --> 00:01:44.100
a background check. 

43
00:01:44.100 --> 00:01:47.533
Some locations require HVACR technicians 

44
00:01:47.533 --> 00:01:49.299
to be licensed.
