Re: To flush or not to flush?
As JWKO said, new filter-drier. Also, the flush would help. You may end up having to evacuate it and re-flush it in a year or two and maybe a TXV replacement. Contaminants from oxidation and moisture tend to come back to haunt you quite a bit in an AC system. If you don't have the capability to do it yourself, it might be worth considering a system replacement and bite the bullet in one shot. If you can do it yourself, don't be surprised if you have to go back in.
