Yup. We used to send new vehicles that didn't have AC to a shop that would add it, when I worked for a dealer (or two). Though I personally would use factory air if I bought a new vehicle (which I did). Back in the day, I was too broke to buy a new vehicle, so I went to pick-a-parts and cobbled the AC systems together.
