ASE A7 Test Prep #1 - System Pressures Diagnosis

This video covers the a/c system performance test and system pressures diagnosis. A few questions related to these topics will be found on the official test. Video shows one of the many ways to perform an a/c system pressure test. The video also goes over possible abnormal gauge readings.

Update Oct 15, 2023: (Feedback after taking the test) No questions about how to perform the "performance test"
There was a few diagrams that showed the high and low side pressures. I liked that the answers were clear if you know how to interpret the gauges. For example, the readings shown at 1:23, let's say there was a complaint of poor cooling to those exact readings and ambient temperature. What could be the cause? A. Clogged Condenser. B. Failed Compressor C. Air in the system D. Stuck Closed Thermostat.
See, the answer is direct, they wouldn't try to confuse you.
I did not talk much about "saturated" dryer elements, or "frozen" expansion valves. Know how these affect outlet temperatures. (Constant problem? Intermittent problem? Not a problem?")
At 1:45 I said the "ASE test does not ask you about relative humidity." There was 1 question about relative humidity in general.
The pressure scenarios after 1:52 are good to know.
