I have an old Honda Odyssey minivan that I keep in MN. and I recently had some work done on it including installing a new A/C compressor and (supposedly) refilling it with freon. I was not in town when the work was done and I suspect that the A/C system was not filled completely. I'm going to have someone throw some gauges on it tomorrow morning to check but I can't remember what the numbers are supposed to read?

What are the magic numbers, (low/high), that indicate the system is full? It's going to be around 40 deg. ambient temp when it's checked, if that helps. TIA!
