Remy set up the swamp cooler and was so easy to work with. I forgot to give him the Fresh Air cube that I bought to put in the swamp cooler to keep the water fresh, and not smelling bad. When I found my error I called Coffman and told them my mistake. I asked if there was any way Remy could come and open up the swamp cooler again and put in the fresh air cube. Remy came back with a cheerful attitude, got up on the roof and put the fresh air in my cooler. It was a good experience having him work on my cooler. He certainly went the extra mile to help me.
