I am moving into a new home and I know that Dish tells you just to leave your dish and they will come out and install a new one. How does this work? I imagine they charge to come re-install the new stuff. I think I heard there is a way to get it for free but I assume you have to sign another 1 year contract which I don't want to do. Does anyone know what the cost would be for install of 2 rooms in a new home?
