Quizplus · Accepted Answer

Leak-checking is crucial when refrigerant lines are to be sealed behind walls or ceilings because once they are concealed, accessing them for repairs or checks becomes significantly more difficult and costly. Ensuring there are no leaks before sealing these lines helps prevent future problems and the need for disruptive and expensive corrective measures.
