AC options. Looking for the best operation AC unit.

[Big Block]

Looking at different options. Have factory AC that hasn't worked for over 20 years. The system is intact. I'm not sure if it's worth the time and money to try to get the old system up and running. We're having one of those summers. Super high humility and temps in the high 90's every day. Don't want to drive anything that doesn't have AC. I was talking to a co-worker who said beware of the gen 4 Vintage Air unit. He said they're having trouble with electronic solenoid. Has anyone experienced that with a gen 4 Vintage Air unit? That's why I have been looking at other options. The stock cables and factory style site glass would seem more reliable than electronics. But like I said this is all new to me.*The Old Air Hurricane unit uses factory AC controls and uses the original ductwork, also has the site glass. Any help is appreciated. Just weighing my options. I don't want to waste time and money on a AC unit that's not going to work in high humility and temps. Thanks
