An AC shop will be able to install ES-12A in either a R-12 or R-134 system.
Any reason to run this over duracool? Read lots of good about duracool.

I don't know. I've never tried Duracool. I have used ES-12A in both R-134 and R-12 systems. It gets incredibly cold.
I would take it to a shop and have them recover the 134 you put in so you can replace that crusty, tired accumulator and pressure switch. Those pressure switches are known to fail and look just fine, much like the junction block sensor in the brake system.
Bump. I have been reading around and maye there is no high side port on this r12 system. How are you supposed to do proper AC work without reading both sides of the system? I have a set of manifold gauges but cannot even use them.
Yeah, Volvo was cool like that. My 93 wagon only has the low side. but it is still good for servicing the system. The refrigerant is sucked out and added via low side. The vacuum is drawn on the low side so you should be fine.
I'm pretty sure the high side port is on the back of the compressor.
Yes but every source I?ve found has said that in order to do proper work, high and low sides should be considered.
That is true if the compressor is an unknown. If you are reasonably confident in your compressor then using just the low side for service will work. I've had mine worked on several times and the shop didn't say anything. They may use some type of adapter that I don't know about but my system is still stock with only the low side port.
