Jack Chisenhall is credited with making climate-control systems accessible by founding the San Antonio, Texas, company Vintage Air, and also helped create what is now the Hot Rod Industry Alliance (HRIA), among other innovations and contributions. His work made enthusiasts’ cars more comfortable and easier to drive, and that meant more miles logged behind the wheel, more money spent on modifications and more time on the road wrenching, driving, building and enjoying these cars. It was a cultural shift and a game changer.
