My husband let the freon out by mistake when replacing my radiator. We need to recharge the a/c with freon.

The low pressure port in the a/c line is the line R134a refrigerant is put in to recharge the system. You can buy a recharge can that has a gauge on it that tell you how much pressure is in the system for about $30 in many auto parts store. Look on You tube there are several good video clips that explain how to recharge the system.
