Can you switch out cable boxes at this location?

Yes and it's just a little wait but for me it was quick.go there

Yes

Yes. I did this a few weeks ago after my home was struck by lightning and took out everything related to cable/internet. I made an online appt through the website. My waiting time was much less, just bring all equipment to exchange.
