So they offer:
and they install cable and phone line/s
The quick answer is we chose to run cable in all the bedrooms and Family room, and put the phone line in the "office".
No Security - The whole "we give equipment for free, but you have to pay for monitoring" is crap. EVERY security company offers the same thing. No thanks.
Home theater - Maybe if I had wanted to spend the money, I would have gotten some Home Theater bling. BUT, I am not finishing basement and can easily add in-wall speakers down the road. Instead, I am installing (pre-drywall) a blue outlet box with a pvc pipe running to the basement on the tv wall and behind the couch wall. SOOOOO, I can easily run my Bose (proprietary) speaker wires my self. I am not doing the tv over the fireplace, but if I was....I would install PVC pipe myself and pull the wires after move in. Guardian wanted $500 to pre-wire the fireplace for a tv!!!! no thanks.
Central Vac - a quick visit to Kirkwood Sweepers proved I can get a better system installed down the road for cheaper.
Now if I wanted to lump this stuff into a 30 year mortgage, it could make sense. But it just wasn't worth it to me.
So, we were able to skip this process this time. We just told our Sales Rep where we wanted cable and phone. Done and done.
