First Rate.
Used to replace a through-the-wall type air conditioner, my new Tripp-Lite is far more quiet, more effective in cooling the area than the 15,000 BTU unit that it replaced, And, it provides control and air direction options that give user choices that are very helpful. I am using the unit in a domestic environment where it has proven to be far superior in every way to other portable units that I have previously bought. I consider it entirly suitable for domestic use. Having been successful in keeping us cool through a long patch of record setting hot weather, it has proved highly efficient and effective. I have already recommended it to others and I may buy additional units for myself.
