Reply to "AC hose question"

If they are still the original hoses, now is the time to replace them. Pressure test or not.

If they have been replaced, was an old-school R-12 hose used, or were they upgraded to the newer 'barrier' hoses needed for R134a.

In either case, how old are the hoses.

To your question, I'm sure you could cobble something together with some fittings, a gauge and a schrader valve to pressurize each hose and let it sit overnight to see if the gauge reading goes down.

Air compressor air can tend to be humid, not something you want to introduce into an AC system. Nitrogen would be best.

In any case, you will need to install a new drier, always needed when a system has been opened to air.
