You got it!
The Haagen Dazs part sounds good...
Business has been good. April and May were record setters. Hopefully, June will start AC $eason if it ever stops raining.
It only dumped another 5 inches Thursday night... The river that's 100 feet from my house should be cresting right about now, but we're high and dry 8-)
Maybe we have different interpretation of 'foam', but when the sight glass shows "air" then you are seeing a lack of refrigerant and oil. It could simply be a void; it doesn't have to be air from improper evacuation.
Typically on R134a systems and conversions with a sight glass, you will see no bubbles at all once the correct charge is installed. {While charging}, the point at which they go away is usually still an undercharged state. Conversely, with OE R12 systems, depending on the heat transfer and localizations within the condenser region, it is generally accepted to see small bubbles during operation. I find this particularly true of FWD electric cooling fan designs especially while high speed fan operation is commanded on, and for a time after the compressor cycles on.
