When we moved to our new house it came with a central vacuum system. But it had a problem and didn't work. I called one company for a repair estimate and it was very, very high. We decided to get a second opinion and called Advanced Homes. They came and I was happy because the technician saw the problem right away. He said it was a small repair and he fixed it for a low price because it was so easy. He didn't take advantage of the situation and obviously knew what he was doing because we haven't had another problem. I like it now that the central vacuum is fixed! Thank you Advanced Homes!
