I'm a general contractor and have used Advanced Homes for at least twenty years. They've worked on a couple of dozen projects for me and I always find them reliable and responsible. They have smart guys who know how to figure things out and their prices are reasonable. Some of the work has involved installing brand new central vacuum systems for my projects. Some of the work is on remodels with existing vacuum units that aren't functioning properly. Advanced Homes knows how to fix and install all different types of central vacuum units. My work spans a large area including Beverly Hills, Encino, Sherman Oaks, and Pasadena, to name a few. I will continue to use Advanced Homes and recommend them highly!
