That can provide some information. Of course, an older unit
will draw more. A dirty unit will draw more. An under
charged unit will draw less.

Dirty and undercharged can cancell each other out.

One thing you can do is take a clamp ammeter around the 220
line and measure the amps.
On mine I measure 6 amps, which probably shows some loss of

but its still working. older AC will draw a lot more amps.
