Absolutely incorrect. If the charge is right in the weather we're having (I'm in Texas too), you should have a clear sight glass. ZERO bubbles in our current weather. Cloudy/foamy/bubbling/opaque sight glass indicates low charge. Yellow suggests they have dye in the system, that should not be present if the system didn't have a leak previously.
You're obsessed with throwing a LARGE amount of money into converting back to R12 when the refrigerant being used isn't the problem.
