12 volt air conditioners

Electric AC systems are the way to go. The Toyota Prius and all Tesla’s have been doing this for over a decade. The length in the line run isn’t an issue. Porsche 356 guys have been doing this for awhile too. Their systems are clean and nearly hidden, but out of the price range for most A guys.

The main issue is the amp draw they require, it takes a big alternator and some modifications to the wiring harness. Not impossible.
