We have been using this company for years and have their systems installed and serviced in three properties. Over the past year, I am sad to say that the level of service and professionalism has completely deteriorated. One of my RO filters was installed incorrectly, which caused carbon chunks to infect my drinking water. The filthy mess of a repair person showed up and proceeded to not only try to charge us for a service call that was due to their error in the first place, he was unprofessional to the point of being abusive. Furthermore, he caused additional problems to the system. When I complained to the owner of this sad organization, we were abused even further and told to take our business elsewhere. He went on to say that he had never had a complaint about this representative. FALSE! I've talked to 3 of my neighbors who informed me that they, too, have stopped using this company because of the same service provider. Do yourself a BIG favor and stay far away from this company!
