Proper way to discharge freon from AC?

E91 Hoarder · 03-19-2022, 06:24 PM

I need to replace the engine, which means disconnecting a/c lines. Cannot drive to the shop - engine is dead. Is there a DIY procedure to properly discharge/recover freon at home? Feels wrong to release it into the air.

No there's not really a way of doing it properly unless you have all the gear. Not sure what country you are in but in Australia there are mobile a/c guys who could come and do this. The other option is unbolting the compressor from the engine and leaving the lines connected.

I'll try do disconnect the compressor and remove the whole thing. Thank you!
