Air conditioning systems have to be recharged with refrigerant every so often.
No, today's air conditioning systems are sealed systems and should last many years without issue.
The refrigerant used will not evaporate or get used up.
If the system has lost refrigerant and needs recharging, it is faulty and must be repaired.
Servicing an air conditioning system takes training, experience, and equipment.
You have no idea if that part is any good or not. We have seen many used parts installed only to find they are no good and must be replaced again. A used part is an unknown and nothing but a waste of money and time. They rarely represent true savings?
