Do you need climate controlled storage?

Climate Sensitive Items

Some storage items require extreme care. That's why Extra Space Storage offers climate controlled storage units. Learn how to safely store your old photos and family heirlooms without losing their value. If you live in an area with extreme temperatures, consider the value of a climate controlled storage unit.

Effects of Extreme Temperature on Storage

  • Cracking, tearing, breakage and warping of wood from expanding and contracting in extreme heat and cold.
  • Yellowing and degradation of fabrics and papers from extreme temperatures.
  • Mold and mildew stains on papers and fabrics caused by fungus-friendly temperatures.
  • Rust, corrosion and weakening of metal which has been exposed to moisture, as well as very hot and very low temperatures.
  • Ruin of electronics by dampness or extreme cold.
  • Warping of items, as well as fading and degradation of sound and image quality.
  • Damage to furniture and fabrics by rodents or insects.

The Advantages of Climate Control

The climate can wreak havoc on stored items in many regions of the U.S. In parts of the South and West, daytime temperatures regularly reach scorching highs during the summer.

Clearly, that kind of heat is just not good for a lot of items,

By contrast, customers in Northern states may own items that are vulnerable to temperatures that regularly fall below freezing in the winter.

Temperature extremes can be tough on everything from wood and leather to pictures and videotapes. Some items may crack or warp. Others may yellow, while documents may become unreadable over time.

Other items that may be susceptible to damage without climate control include:

  • Bedding and mattresses.
  • Sports equipment.
  • Metal appliances.
  • Books and other paperwork.

Climate-controlled storage reduces these risks by using heating and cooling units to keep the storage space at a safe temperature, usually at a level above freezing and below 80 degrees,

Humidity: The 55 Percent Mark

Units that also offer humidity control keep humidity levels around 55 percent. Humidity is particularly dangerous to a variety of items.

High humidity can cause photos to stick together, or wood furniture to warp, or leather goods to crack.

Electronics, artwork and items such as pianos also may sustain damage from too much moisture in the air,

If you own an item that's especially sensitive to humidity, search for a storage unit that actively dehumidifies the air. Units that simply cool the air with air conditioning may not bring moisture levels low enough to protect all items,

The true sweet spot for items that are truly sensitive to high humidity levels is around 55 percent,

The cost of renting self-storage with climate control varies widely-anywhere from 20 percent to 50 percent higher than traditional storage. It's all based on supply and demand,

The extra cost of climate control-often referred to as the "climate control premium"-typically adds up to 35 percent to 50 percent. A standard 10×10 storage unit with climate control might cost $140 a month to rent, while a unit without climate control could cost $90.
