Grdenko,

Are you sure its the evaporator leaking? It might just be where the hoses and valve connect to it. Just because a freon sniffer detects freon in the air stream, doesn't mean the evaporator itself is leaking.

I replaced my evaporator twice and it still leaked because it was a connection, not the evaporator itself. The freon detector will detect freon but does not always detect where the leak is. The leaking freon will disperse quickly and the detector will start beeping but you don't know from exactly where. Check for leaks around the connections with soapy water and look for bubbles.
