We're very satisfied with the work Advanced Homes has done for us over twenty-four years. The system itself was already installed when we purchased our home and Advanced Homes has had great customer service, quality products and professional workers. The techs always arrive when they say, get the work done in a timely manner and clean up after the work is done. We have never had a complaint, they have been very good. I would gladly recommend them to other homeowners with Central Vacuum services.
