c) Nitrogen testing
d) Charging

Answer 1

Leak testing of the air-conditioning system is recommended to catch any masked problems that did not appear when the original problem was diagnosed.

Step-by-step explanation:

A) Leak testing of the air-conditioning system is recommended to catch any masked problems that did not appear when the original problem was diagnosed. By performing leak testing, you can ensure that there are no leaks in the system, which could lead to a loss of refrigerant or decreased performance. This is especially important after repairing the system to make sure that no new leaks have been introduced.

Leak testing involves pressurizing the system with a mixture of refrigerant and nitrogen, and then using a leak detector to identify any leaks. This helps to identify any hidden issues that may have been missed during the initial diagnosis.
