Climate-controlled storage units help keep temperature-sensitive items at an even temperature in cool or hot climates. We recommend using climate-controlled storage for extra peace of mind when storing items like art, furniture, textiles, paper products, and more. * CubeSmart uses reasonable efforts to maintain a Climate-controlled temperature in the building where the Cube is located of between 55 and 80 degrees Fahrenheit. The climate Controlled-control storage units may be accomplished through any type of system including, without limitation, “swamp coolers.”
