No, today's air conditioning systems are sealed 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.
The truth is, it has changed dramatically.
Servicing an air conditioning system takes training, experience, and equipment.
When refrigerant leaks out of the system, it also leaks oil out.
Like a car engine, the air conditioning system has oil to lubricate the compressor and its associated parts.
Like an engine, too much or too little oil is not good.
It’s impossible to know how much oil is in the system by recharging the A/C system.
So, recharging it for the summer is dangerous and does not fix the issue.
Also keep in mind the impact on the environment the refrigerant is having when you knowingly allow it to leak out.
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.
