I am looking at purchasing a natural gas 20k standby generator.The choices are generac,kohler,c ummins onan. Is there one that is truly more reliable than the other?And if so what makes it more reliable.
When we were taking a look for our home generator we had this same issue. The few top brands are tough to tell apart and there seems to be a wide range opinions. There are lot's of guides and articles out ther ebut Here is one I found specifically helpful when making my decision. I ended up choosing generac due to it's reputation, but hopefully this will help you decide which brand is best for you..
