I thought the service that I received from Advanced Homes - Central Vacuum Services was very, very good. I had two guys come out recently regarding two separate issues I was having. They helped me replace a couple small doors on the vacuum system that were loose and on the verge of coming off from general wear and tear. That went very smoothly and it looks great now. They also helped me out with another checkpoint on our sliding door that was faulty and that went very well also. I was very pleased with the quality of work and have never had any issues with them since they installed our unit years ago.
