We have been using Advanced Homes - Central Vacuum Services for quite a while now and they have consistently provided us with excellent customer service since they first installed our unit! Recently, we had requested they stop by to check up on our system and install some new bags for us. They were on-time and completed everything we needed them to very efficiently. We had questions regarding alternatives to turning on the machine in the garage and the technician was able to provide us with info on a new technology that allows you to turn it on with a remote and we are currently looking into that. I would highly recommend their services.
