Tim:

It is an R 134 system. I just serviced it a couple of weeks ago. I replaced most major components back in 2017 after I bought the aircraft with an inoperative AC. Parts are not difficult to find.

I have the 134 serviced every year during the annual. Easy to do.

The only tricky part to it is changing the AC compressor belt if you have to. Takes a bit of time as you have to remove the upper rear cowling...

Thanks for all these comments. My system is indeed a 134a system, but there is precious little documentation. My AP asked me to ask the group if anyone knows how much the system takes, and what to pressurize it to. He doesn't want to over pressurize it, but none of that is written anywhere.

My AC system was serviced in Feb 2019 when some new components were installed by someone long before, but it isn't hardly working at all now. Shouldn't leak down so quickly; he is getting 134a with dye to look for a leak.

Any advice?

Any advice? Pressure? Volume? PV=nRT (still remember that much!)

Thanks for all the help on this. My A/P reports the recharge (with dye-laced refrigerant) was successful and it is chilly inside now. He will watch for leaks.

My rear alternator has gone bust. It's always something. I go through alternators like some folks go through water. Not the coupling this time, it's the windings, maybe still under warrantee. I've learned having an extra alternator on the shelf is worth it so will go and buy one.
