Best Answer

Moisture in a vehicles AC system can react with the R134a or R12 refrigerant and create an acid that will eventually eat through seals and o-rings and even orifice tube parts.

It is recommended you vacuum your system whenever it loses charge or whenever your extremely low on refrigerant. You can rent a vacuum at Auto Zone for free (200$ refundable deposit) and pull a 26-28 inch vacuum.
