My parents have a 20KW Generac. 2 years ago we had a really bad wind storm late in the summer that took out power for about 10 days. Their generator ran nonstop for the entire time. You couldn't tell the power was out except for the sound of the generator running. Theirs in on the opposite end of the home from the bedrooms so you couldn't tell it was running on that end of the house. A/C, lights, well pump, all appliances ran normally. They are contracted with a guy who services the unit once a year. If I was in the market for one, I'd buy a Generac based on that experience. They have had no problems with the unit since new. Ironically enough, it was new a few months before the power outage.

One note, you need to make sure your line from the tank to the house is big enough to run the generator and any other propane appliances. We installed a designated supply line from the tank to the generator and kept the house separate so there would be no supply interruption.
