I just installed my 4th Breezaire Unit. Like most machines/devices they work well for a long time and then slowly fade away. The best part of a new Breezaire is how easy it is to install. My wall opening space was already built for the 22 1/4 x whatever space of the unit so all me, my son and a friend had to do was work the failed unit out, then push the new unit in. Plug it in and it started working immediately. Overnight the temp in my cellar with 6,000 bottles dropped from 71 degrees to 65 degrees. At the end of the next day the temp was blowing at 58 degrees and the wine temp was 60 degrees. I have a pipe to direct the water from the drain to the outside. Not sure if we were supposed to pull something out of the bottom but wound up positioning a funnel under the drain hole attached to the drain pipe. All is well that ends well. My wine is happy and I am happy.
