We bought a house about 4 years ago that already had an ADT system in it. We went ahead and got service through them because their equipment was already installed and we didn’t have to pay anything upfront, just the $36 a month for monitoring. Long story short, after years of battling with ridiculously expensive service calls and our monitoring be raised to $73.40 a month we decided to part ways. After enough shopping and consideration we decided to go with Barcom. They were able to take over the existing system, warranty all of our equipment and cut our bill in half! I wish I would have known this was possible 4 years ago… Anyway, I have been very happy with this transition and have nothing but great things to say about the service I have received from Barcom. If you are in a similar situation and looking in to other options these guys can help!
