Has anyone tried out this new AirCycle fan yet? It sounds pretty useful. Its a whole house fan that installs in your sliding patio door instead of in the attic. I attached a copy of the ad that was in the Corpus Christi Caller Times this morning. It says it can cool down your whole house and uses much less energy than A/C. I'm thinking about ordering a couple, just curious if anyone else has tried one out yet.
