Yup,,,,We have a K2 model and live in San Diego County. It's a very nice unit; works well in dry SoCal type climates. We cut out a piece of masonite and velcro it to a bedroom window; cut a 4" hole in the masonite and attached a duct fitting; open the window, cover the screen with the masonite, attach the 4" flex hose that comes with the K2 to the duct fitting and to the K2 unit; cools off the bedroom area quite nicely in our Host camper. During the winter, I run it w/o water to produce "white noise" and air flow.....I think it was a very good investment.
