* Our climate controlled / heated storage units mimic storing items indoors. Our heating and cooling unit is set such that heat is blown into the storage units when the temperature is 55 degrees. A fan circulates the air in a cycling pattern over a 24 hour period. When the temperature hits 80 degrees, our cooling unit is activated and the circulating fan once again moves the air. Antiques, sensitive electronic equipment, musical instruments, art work, books, photos, etc. are but a few items that one may consider storing in a heated storage unit.
