Our central vac had very little suction. I found Javid (AMP Electric Vac) on Homestars and called to see if he could help. He tried to solve the problem over the phone in order to save me the service call charge. We were unable to fix the problem, so Javid came over the next day. I was very impressed with his professionalism and expertise. He was able to unclog the tubing. He also provided tips to prevent clogs from happening. He also cleaned my central vac filter. I am pleased to say that the suction our central vac system is the strongest it's ever been. It's like we have a new system. I highly recommend Javid as he is honest, professional and a true gentlemen.
