air conditioner
I recently placed a can of r134a refrigerant into my Lexus gs350 F sport, 2013 model
shortly afterwards, compressor started to make funny sounds and hot air coming out, instead of colder, it got worse.
I figured I overcharged it so I turned it off , waited about a month and when I turned on the AC, it started working again without any problems
I check pressure on the low port and it registered on the lower end of the GREEN markings (adequate charge)
After about 5 months, air conditioner not working again and there is an intermittent strange noise from compressor
Is it possible that compressor got ruined on that initial overcharge or what do you think? possible leak in system or something else?

Refrigerant should never need to be added to any A/C - whether it is a vehicle, a residential central HVAC, a refrigerator, or a freezer. The refrigerant is in a 'closed-loop' system and should never leak or become low.
When was the last time you (or anyone you know) had to add refrigerant to a refrigerator or freezer? NEVER!
You should never (EVER) need to have a vehicle's A/C serviced - much less to add refrigerant.
I don't know what damage, if any, you may have caused your car's A/C, but your action was because of pure and simple thick-headedness (a.k.a. stupidity).
