The dryer needs to be changed every time the system is opened to the atmosphere. It absorbs any residual moisture inside the system. If too much moisture is in the system it'll form acids that'll eat the insides of the system over time.

When I was buying my CE, I was told the system had a slow leak and dreaded that it might be the evaporator.
They put dye in it and turned out to be o-ring leaks around the expansion valve. I split the cost with the seller and have ice cold air.
