This company installed a Generic Generator for my family. Not only did it take a long time to install the product, but there were some misrepresentations they made about the product. They never showed came back and showed anybody how to operate the generator. When it did come on after an electric outage, the generator ran out of oil after it ran for eight hours. When they installed it, it never had the proper oil in it. They came over twice and said they fixed it and it ran out of oil again. After they said they fixed it they sent me a bill for $379.00. Elissa, the owner of the company passed on doing anymore warranty work on the machine and got another company to do anymore warranty on the generator. The new company said that Preferred Electric had put the generator back together wrong and then put it together the correct way. About a month later Preferred Electric without my knowledge billed the credit card I had originally given then for more money ( $647.00 ). It seems very unethical of them tag my credit card for money without telling me. read more
