My air conditioning continually losses gas over about a month. I got a new compressor but the rest is original. Shops pull a vacuum test and can't find a leak. I think it my be the hoses. Also it has has been converted over to the other gas 134a.

Is it possible to change out the 3 hoses with the body on?

Do I really need to get a new condenser?

Where is the best place to get the proper hoses?

Thanks as always!!!
