I purchased a Generac 22 KW whole-house generator from Oakwood Electric and Generator in October of 2020. With the supply chain issues, they could not install the generator until March. Last week the generator was exercising (which it does once a week for 5 minutes) when it literally BLEW UP (see pictures). This week Oakwood sent their tech out to look at the machine. And, after doing a 10-minute visual inspection he said, "I have no idea what caused this." However, though they have “no idea” what cause the explosion, they think everything will be just fine if they replace the damaged parts (instead of replacing the whole machine). They ordered the parts damaged by the explosion. So put yourself in my shoes: • You spend 10K on a new generator so you can have Peace of Mind in case of emergency. • The thing blows up after 5 months of operation. • The vendor you bought it from refuses to do anything more than replace those parts visible damaged by the explosion. • Then, every time there is a storm, you get to wonder and worry whether the generator will perform to standard if the power fails. You get to wonder and worry about whether your basement will flood if the generator doesn't work. The folks at Oakwood said, "We can't prevent your machine from failing." They also told me if I wasn't happy with their service, I could work with another Generac contractor (right - because they don't want to deal with the warranty work)! The lady at Oakwood sent me a copy of the warranty and told me to "call Generac" if I was not happy – which I have done. DO YOURSELF A FAVOR - BUY THE KOHLER! It's a little more expensive, but my brother has had a Kohler for 20 years and never had these kinds of problems. Generac is cheap (plastic) and the company does not stand behind their product. I have nothing else to say about Oakwood.
