Compare climate-controlled storage companies
Public Storage and Life Storage both offer temperature and humidity-controlled storage, but you’ll be paying more. U-Haul offers both at a much lower price, but their low customer review score may be an issue for you. You can get temperature-controlled storage at the same price point with Extra Space Storage.
What should you look for in a climate-controlled storage company?
- Temperature controls. Look for a unit that keeps your belongings within a temperature range of about 50°F–85°F. Be aware that recommended temperatures for your particular belongings can vary. For example, you should keep wine closer to 55°F, while vinyl records do best between 65°F–70°F. Your local storage unit company can give you more guidance on your specific items.
- Humidity controls. Very few companies offer humidity control, so if you’re interested in it, the first thing is to verify whether they have it. After that, you should ask about the specific relative humidity range of the unit and see if it’s a good fit for your belongings. Humidity-controlled units are ideal for areas with high humidity (think coastal areas like Florida or Maine) because they fight against mold, mildew, rust, and rot.
- Low prices. Don’t pay more than you have to. Our research shows that you can usually get a climate-controlled unit for about $190 per month.
- Do a quick Google search for company reviews. Low prices don’t matter much if the company treats you poorly or has tons of complaints about damaged items or hidden fees.
- Many storage unit companies have excellent value but are available in only a few hundred places across the country. Be sure the company that you like has a nearby location.
Relative humidity is a measurement of water vapor relative to air temperature. Your local storage unit company should be able to tell you the relative humidity of its units—and whether they’re safe for your moisture-sensitive belongings.
What is climate control?
Climate control monitors a storage unit’s temperature and/or humidity. Storage companies use the term in different ways. The general idea is that there is some kind of monitoring system (temperature, humidity, or both) in place to extend the life of your belongings in storage.
We’ll break down some basic info, but availability and the way a company defines climate control can vary by location (even within the same company). We recommend contacting your local self-storage facility for more information.
For our rankings, we include companies that monitor temperature levels, humidity levels, or both.
Questions to ask before getting climate control
What is the climate like?
You likely want to get climate control if you live somewhere with extreme temperatures or humidity. Similarly, look into climate control if you live somewhere with big temperature or humidity swings. You generally want the temperature inside of your storage unit to stay around 50°F–85°F.
Big temperature swings can damage belongings in storage. In the last two decades, extreme temperature fluctuations have affected states like California, Arizona, and Florida, with temperatures changing as much as 45° in a single day.
What belongings need climate control?
Climate control is ideal for items that don’t do well in extreme conditions. There are several belongings that many storage unit companies recommend for climate-controlled units:
- Clothing and fabric
- Wooden or leather furniture
- Household appliances
- Important paperwork
- Musical instruments
What temperature range should I look for?
The temperature range of your climate-controlled unit should match the belongings you plan to store. Since different items do better in different temperatures and humidity levels, it’s important to ask a storage expert what works best in your situation.
Temperature range (F)
|Instruments||65–75 degrees||40–60% humidity|
|Wooden or leather furniture||65–75 degrees||50–60% humidity|
|Electronics||50–80 degrees||30–40% humidity|
Data collected 12/16/22. Ranges above are based on several sources. Contact storage rep for more info on how to store your items.
To help keep humidity levels low, store moisture-sensitive items like electronics with silica gel packets. These are a cheap alternative to soak up excess moisture when you need to store electronics with other items in your unit.
