A central vacuum is a permanent vacuum system that's installed throughout a building. It uses a central motor to suck dust, dirt and allergens through PVC pipes into a collection unit. A central vacuum's motor unit is usually located in a basement, garage, or utility room. A network of PVC pipes runs through the walls of the building and inlet valves are installed in walls throughout. To clean, plug a lightweight hose with cleaning attachment into an inlet valve. We have been in business for over 30 years. We solve problems and tackle projects that others have tried and failed. We are professionals who do one thing and one thing right and we are the best at what we do.
