Text: Heating & Air Conditioning Summer
2001 Student Activity Manual
Purpose: This course is designed to
introduce the student to the basic operating principles of and repair
procedures for automotive heating and air conditioning systems. Troubleshooting
and repair of the systems will be stressed.
Grading: Grades will be based
on the following:

Performance
tests will be given to give the student opportunity to prove he/she has
learned diagnostic skills.
A quiz may be given every other day. A missed quiz can not
be made up. The lowest quiz score will be dropped and not figured into the
final grade. Each student may be required to write 5 quiz questions as part of
their quiz score. These are due before the quiz and will not be accepted late. There will be no unit tests in
this course.
There will be no unit
tests in this course. A comprehensive final will be given.
A daily lab log will be
kept by each student. The student will record his/her lab activity for the day.
The daily lab grade will be determined from the students' log. Any lab sheets
will be turned in with the log. The log must be turned in daily.
A log not turned in will result in a zero for the daily lab grade and lab
assignment sheets. The log entry must include the following: Name,
Day & Date, Description of the lab activity (minimum of five
sentences), Two things learned that day, Difficulties experienced
that day and Description of the best part of the day.
Lab work will be
graded in two ways:
1. Lab Assignment sheets.
2. Daily lab on a scale of 0-4.

Course Competencies/Outcomes
for Heating and Air Conditioning
After completing this
course, the student should be able to demonstrate a basic understanding of the
operational theory of the following systems and/or components:
1. Demonstrate a knowledge of air conditioning and heating
system principles.
2. Demonstrate safety habits in repairing air conditioning
systems.
3. Demonstrate proper operation of air conditioning
recovery/recycling station.
4. Demonstrate the proper charging of an A/C system by weight.
5. Perform basic diagnosis of refrigerant systems.
6. Repair refrigerant systems.
7. Demonstrate a knowledge of laws governing the use of
refrigerants.
8. Demonstrate proper use of an electronic leak detector.
9. Perform cooling system service including: pressure test cap
and system, inspect coolant condition, hose and belt
..inspection
and service and heater control valve inspection and service.
10. Drain, flush, refill and bleed cooling system.
11. Check cooling system for proper operating temperature.
12. Check cooling system for combustion leaks.
13. Identify, label and store refrigerant.
14. Inspect and diagnose vacuum, mechanical and electric motor
operated air distribution systems including; mode,
..blend
and recirculation airflow components and control panel functions.
15. Inspect and determine needed repairs of electrical and
mechanical cooling fans and related shrouds.
16. Diagnose A/C system problems that cause the protection
devices ( pressure, thermal, and PCM) to interrupt
..system
operation; determine needed repairs.
17. Inspect A/C compressor drive belts; replace and adjust as
needed.
18. Inspect, test, and replace A/C compressor clutch components
or assembly.
