Question

Technician A says that the recommended oil for most R-134a systems is PAG oil. Technician B

says that the recommended oil for R-12 systems is mineral-based oil. Who is correct?
O Technician B only
O Both A and B
O Technician A only
O Neither A nor B

Answer 1

Both Technician A and Technician B are correct.

The correct answer is: option 'Both A and B'.

Step-by-step explanation:

Technician A and Technician B are discussing the recommended oil for different air conditioning systems.

Technician A is correct when they say that the recommended oil for most R-134a systems is PAG oil. PAG oil is a synthetic oil that is specifically designed to work with R-134a refrigerant, which is commonly used in modern air conditioning systems.

On the other hand, Technician B is also correct when they say that the recommended oil for R-12 systems is mineral-based oil. R-12 refrigerant was commonly used in older air conditioning systems, and mineral-based oil is compatible with it.

Therefore, the correct answer is that both Technician A and B are correct.
