Having a central vacuum system in our home, we've counted on Advanced Homes - Central Vacuum Services to maintain and repair our system through the years. Recently, we had them out to perform maintenance. The guy was very professional, nice, and did a thorough job. He made sure to check everything, including the hose and did what he had to do. We continue to use their company, not just because they're specialists, but because we can rely on them to get the job done right the first time.
