Yes! Central Vacuum Experts specializes in ‘retrofit’ installations and we are one of the only ones in the Triangle area doing it.  Our team of installers has installed central vacuum systems in hundreds of existing homes and businesses. Because each project is unique, we give you a thorough onsite review to let you know where the inlet valves are likely to be placed. We can run piping and install units with virtually no need to do drywall repair. One big advantage of our expertise is the assurance of most effective airflow by proper placement of pipe and the power unit.
