I myself, work in the contracting business, and we compared notes on fake companies stealing the names of legitimate operations. We had a pleasant conversation, and, I would say anyone interested in water filtration or solar energy, would do themselves some good by contacting this company.DO NOT CONFUSE this Energy Savers with the fake telemarketed Energy Savers. And, while I am at it, let me give this advice: if you are called by a telemarketer, attempting to set up a free appointment or evaluation DONT DO IT! Just call this Energy Savers, and theyll set you right.
