Climate controlled storage units can be a great place to store items you want to store that may be affected by extreme heat or brutal cold temperatures. Since units are all closed up all the time until you open the unit the heat can become a very serious problem. If the sun is out all day long then your unit is going to be exposed to the sun all day long, with no ventilation by the end of the day the unit could reach anywhere from 10 to 20 degrees more on the inside. If it’s extremely cold it probably will not be much colder on the inside but coldness can be a very threaten weather condition to certain items you might put in the unit. Automobiles are probably one of the reasons most used for a request of a climate controlled storage units, and since this is true there are storage units around the United States that are dedicated only for the use of storing automobiles. These units are usually well priced especially if you are going to reserve a unit year in and year out. But maybe you don’t have a car but an expensive drum set or other music equipment or electronics. The best way to know if your items you want to store should be stored in a climate controlled environment is do your research, read the owner’s manuals, consult the company, or research the internet, if the item you are trying to store can be effected by unfavorable temperature then you will be able to find this type of information somewhere.
