[DML] Re: Advice on AC lines

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

It's not that they lines get messed up but die from age. Especially
the discharge line going from the compressor to the condensor coil. It
sees the highest pressures and temperatures. I would at least replace
that one. There is no way to inspect for impending failure, at least
not visually. I also suggest draining as much of the old oil as
possible and filling with fresh. And new service valve cores.
