Yes that is a house Air Conditioning unit in the window with a gasoline powered generator powering it !!!
So when the guy goes to the gas station, he has to fill the gas tank on the car, and the generator. I think if you take a step back and look at this scenario, you could sell the generator and A/C unit and have more than enough to fix your A/C.
Thanks to my friend Randy for posting this picture on Facebook. It was taken in Reading PA, at a Walmart of all places… go figure !
