Ted, I had similar trouble last year when I showed up at Lake Havasu City, too early (Sept. 2012) the air wasn't working all that good. A local told me he thought (which he was right that) that there wasn't enough humidity in the air, at that time the humidity was only 8% as the winter season went on my air got better! I hope you have a similar problem that doesn't cost you $$$! Good Luck, Rooster
