Having decided we wanted a whole house backup generator, I researched the quality and performance of the various brands available. A local general contractor told me that Kohler was the very best brand available; this was confirmed in Consumer Reports. On the Kohler website I found a list of installers in the Cincinnati area and from Angie's List found several with good ratings. I selected Riverside Electric to work with. I sent an email to them via their website and got no response. I then called twice and finally spoke to Scott McDonald who is the sales rep handling generators and arranged a visit. He did not arrive as promised but when I did reach him he said an emergency had prevented him from getting to my house. We rescheduled for two days later. Scott arrived as promised on the second date and was very knowledgeable about generator sizing and location restrictions. I had told him during our initial phone call that I wanted a Kohler generator and as he was leaving told him that again. He told me that Riverside could provide a Kohler and that it had a longer warranty than a Generac but that it would be about $2,000 more than a Generac. He also said that Riverside had installed many Generac generators and had all the repair parts needed and therefore could provide 24 hour service 7 days a week. He said that with Kohler service would be limited to business hours on Monday through Friday. I was shocked to hear this but nevertheless did instruct him to quote a Kohler generator. Scott said he might get the quote out over the weekend but at the latest he would get it out the following Wednesday. I then called the Kohler home office and asked about their lack of service. They told me that Buckeye Power Systems, their master dealer in Ohio with a branch in West Chester, was fully stocked with repair parts and provided 24 hour service 7 days a week, including an annual inspection. I then called the Buckeye West Chester office and spoke to their Sales Manager who confirmed their service program. I told him of my experience without identifying anyone and he said "that was Scott McDonald at Riverside". He said that this was happening quite often and it was very unethical. He gave me the name of two other electrical firms who install Kohler generators and we have selected Deyhle Electric. One final note, as of two weeks after Scott had promised to give me a quote within five days, I still had not hear from him. I called his office and left him a voice mail message that he did not need to complete the quote as we had selected another installer. So if you want a Generac generator, Riverside may be O.K. But if you want to a Kohler don't bother.
