Even if there's a leak, there will most likely still be pressure in the system even if not enough to kick on the compressor, so the fact that you heard a hiss when you were loosening the condenser doesn't mean there isn't a leak in the system.

awesome. That was my theory as well - still *some* pressure, but not an adequate amount.
It seems the condensers are the biggest source of leaks, hence my initial replacement. I'll see what a shop with equipment can dig up while testing. The gauge will read 0 on the low pressure now, because I just drained it while replacing the condensers.
If a leak not in the condenser...
1. There seems to be some denting of the AC by the front passenger lift point :| I've been pretty careful, so my bet is someone else lifted the car by it. I don't see any punctures, but it has clearly been dented there.
2. I let a family friend drive the vehicle, who drove it over a rough surface *crunch* I hope the lines are not damaged (the fact that the dent is directly next to the lifting point makes me think shop dent from years ago).
edit - replaced condensers, not the evaporator (which is in the heater core and i desperately do not want to replace).
