Worked on a 1997 coach yesterday solving some a/c issues, system not really serviced for a while. The front ac evap is 43ft from the compressor utilizing an expansion type device. We can't find anything telling me the charge in the system.
Suction is in the low 20s which is rather low for 134a. I'd like to remove the charge completely and start over but am not sure how to recharge the sys.
I did put some freon in it since it's unlikely those rubber hoses or the compressor itself haven't leaked some in the past 13 years. The supply air was at 61° which is not good.
Anyone have any suggestions on how to go about this?
I posted here for exposure and the fact it's mobile ac not what we all do all the time.
