Call vintage air and get the name of the nearest dealer that also installs. My dealer helped me out a lot (I installed it myself). He crimped the pressured lines and ordered a couple pieces I ended up needing for free.
If you take it to a non vintage air installer and there is a problem with the unit, they will charge more to take it out and charge to reinstall when replaced.
You shouldn't have a problem, but you never know. I'm assuming of course there is a Vintage air dealer that also installs near you.
