Which of the following statements about moisture in R-410A systems is true?

Moisture in R-410A systems is a significant concern because it can lead to various operational issues, including freezing of the refrigerant and corrosion of system components. When moisture enters the system, it can combine with refrigerants to form acids, which can damage metal parts and components over time. Additionally, moisture can result in the formation of ice in the expansion valve or evaporator, leading to blockages that reduce efficiency and can even cause complete system failure. Thus, managing moisture is crucial for maintaining the integrity and performance of R-410A systems, making the statement regarding the operational issues caused by moisture accurate.
