Nah, the system is pretty simple, and competent AC repair shop can handle it.
How slow is the leak, i.e. after a full charge, how many weeks / months / years does it take before you lose cooling capacity?
I've found the high pressure service port to be a common leak point. I've had to replace several of these valves. Get OE/Genuine port only. Details here. If the system is discharged, I'd highly recommend replacing this proactively. The AC compressor usually leaks oil out the front shaft seal but rarely leaks refrigerant.

I think it took about 2-3 years for cooling to slowly degrade. Two years ago, I refilled and lasted about a day. Last year I didn’t bother to look at it but planning to take a look at it this year.
I wilt replace the port and also run the dye to see if I can locate any obvious leaks and then turn it over to the pros.
Thx

2-3 years is a slow leak, something like the service port. But if it stops cooling after 1 day, that's a MAJOR leak. Hopefully not the evaporator. If it is the evap, I'd try Cliplight or Cryoseal first. Hard to pinpoint the evap without charging, then pulling the blower motor to see if there's visible oil / dye at the evap face.
I replaced this high pressure Shrader valve on my car and it stopped a slow leak. Great advice Dave. It’s up to $16.59 now but if you have to open the system for any reason it only takes a few minutes to change even if just for proactive maintenance.I've found the high pressure service port to be a common leak point.
