You may notice that your Mr. Slim indoor unit won't shut on and off all the time like central or window-mounted air conditioners. This is because the unit is actually saving electricity by not turning itself on and off, which is where the most electricity is used and wasted. Running at a slower variable speed our VCSI technology actually uses less energy, which is a good thing when your electric bill comes.

On the inside, Mr. Slim uses R-410A, a non-CFC refrigerant that works more efficiently and poses virtually no danger to the ozone layer. With continued improvements in air conditioner technology, Mr. Slim keeps your home cooler while keeping your energy costs down. And that's great, both for you and the environment.
