Anybody know what the approximate refrigerant charge level the A/C needs? I do auto repair, but one of my best customers just bought this for his business and wants me to charge the A/C. I think there is probably a leak, but want to get some dye in the system and let him run it for awhile. Thanks.

I hate it when people put dye in these systems, in my experience many more issues caused by the dye than help in finding leaks, I use a Freon sniffer, just my two cents
I only use 1/4 oz of dye. Some people think more is better. I have never had luck with a Freon sniffer. When I think I find the leak, I would hold it out in open shop air and get the same alarm. It was not a cheap one either. Changed the sensor tip with the same result. Have not used one much in at least 10 years.
Remove the front grill and check for corrosion of the condenser and connecting line, the receiver drier is also there, The frontal area is somewhat susceptible to damage from impact but even more vulnerable to accumulations of corrosives such as calcium chloride. Have replaced several and connecting lines also. Pretty much the same results with a sniffer from Snap On.

I have used dye for leak checking for years. Never had any problem with things plugging up. You really don't need a lot to find a leak. BUT.....many dyes are contained in cans of stop-leak for A/C systems. That will plug things up! Maybe your experience involved do-it-yourselfers adding a can of aftermarket refrigerant that had stop-leak and dye in it. Given the miniscule amount of dye that would normally be used, I cannot see how it could plug up anything.

Our former mekanic charged the system with nitrogen. Add a little more til he found the leak or the bad part let go.
A quiet shop helps.
