We had a central vacuum that was quite old and originated with our house, and it finally burnt out. The motor had burned out and we called Advanced Homes Central Vac to come out and diagnose the system. The technician Mark diagnosed the problem and we realized that instead of replacing motors, it was more cost-effective to replace a new machine. After they removed our old one and took it away, they were able to install a good, updated and quieter vacuum system and all is working well. They also checked out all of my outlets while they were out here.
