HotRod Air was started by some ex-employees of Vintage Air (if I have my story correct).

They both seem to be about the same price.

We have done two Vintage Air units in the recent, both worked fine. My theory is that you need the biggest evaporator and strongest fan that you can find for a large-volume car. When I have the air on, I want my hair to be blown just like a roadster.

We ran both the units using a stock GM compressor (99 Silverado serpentine setup) and everything works fantastic. We also used the new Aeroquip line and fittings..... they assemble like an AN fitting and dont leak...... was easier than using crimp collars.

My only complaint is the lack of filtering on the evaporator....eventually the evap core will get dirty and start to weep.... in one vehicle, you'd have to disassemble the dash to clean the core.
