I hate to be that guy… But if you research Classic Retrofit air-conditioning here on pelican, there are several threads, including my own to discuss their system, the BTU it uses, the alternator requirements, their blower requirements… And in the course of doing that you will learn a lot about their AC system yes, and electric AC systems in general in our cars. The BTU question above for one has been answered many many times in those threads. Just saying.

My Classic Retrofit system would freeze easily if it was not for their electronic control unit, that has freeze protection built into it. And that freeze protection is adjustable in the ECU based on where you place your sensor and doing your own testing in your own climate under your own personal driving conditions. Again, not trying to be that guy, but reading through a few of those threads would answer 90% of the questions.

I actually looked into doing this myself and then I decided not to bother reinventing the wheel, duplicating all of the testing Classic Retrofit had to do, figuring out where to source an electronic control unit, etc. I just bought their generation one unit and I’ve never been happier, and I’m in Florida.
