Evacuation levels by charge size and equipment date, major repairs, and system-dependent limits.

The question

Which of these repairs on a 70-pound R-410A system is not a major repair, assuming the opening is small and brief?

• AReplacing the evaporator coil
• BReplacing the condenser coil
• CReplacing the expansion valveCorrect answer
• DReplacing the compressor

Why “Replacing the expansion valve” is correct

Only removal of the compressor, condenser, evaporator or auxiliary heat exchange coil, or a large and long opening, makes a repair major. A thermostatic expansion valve is not on that list, so swapping it with a small, brief opening is non-major.

• Replacing the evaporator coil — The evaporator is one of the four listed components.
