Then your not charging enough for refrigerant, or your time. The owner will
have to feel pain in his wallet before he *does* anything. At the same time,
your not charging enough to replace the evap on that old POS. You got to
charge enough to make him *WANT* to replace the system, and be happy about
writing the check for replacement.

Hotshot, like 409a, needs to be dispensed as a liquid. It's
a three gas blend. I'd ideally like a gas that is a single
gas. Like 12, 22, 134a. So I can charge the system wtih
vapor.

How are you charging R134A? As for dispensing any mixed gas.. send as a
liquid to the gauges and then use an inexpensive device on your gauges
to transfer it to a gas as it is charging. In many cases you can charge
by liquid by carefully charging slightly over the target pressure. 20
lbs over in automotive seems to work for residential/commercial as well.
Weighing it in is the best. It is time you learned to charge with liquid
etc.

CY: I havn't yet used 134a on the restaurant cooler. I'd
like to, it's so much easier to charge.

CY: I've got one of those "chargefaster" orifice gadgets.
I'm not all impressed. Tends to freeze over, and shut the
flow down.

CY: I do have a scale, and do try to charge by weight. With
a sight glass in my gages, I can feed liquid, hold the gages
on their side, and the vapor goes into the blue line. It's a
bit of a PIA compared to open the tank and stand back and
watch.
