Best Climate-Controlled Self-Storage Companies of 2021
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 50–85°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 65–70°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 $200 per month.
- Reviews. 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.
- Locations. 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 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 because 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 50–85°F.
Big temperature swings can damage belongings in storage. In September 2020, it started snowing in Denver, CO, only 24 hours after the city was in the 90s. Areas like this are good candidates for climate-controlled storage units.
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
- 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, it’s important to ask a storage expert what works best in your situation.

What sets Extra Space Storage apart?
Helpful climate control info
Extra Space Storage has some of the highest-quality climate control info we’ve seen. On its website, the company walks you through specifics on climate control, which of your items it applies to, and overall benefits in using a climate-controlled unit for your stuff. It focuses on several key issues:
- Climate control definition. Extra Space Storage spells out climate control so you don’t have to guess what it means. It recommends a specific temperature range for storage units holding sensitive items that might be damaged by extreme heat or cold.
- Temperature range. It’s like pulling teeth to get some companies to tell you what their storage unit temperature range is. Extra Space Storage specifies that the range for keeping your valuables safe is between 55°F and 80°F.
- Climate control benefits. Climate-controlled units give you the peace of mind in knowing your sensitive items are okay sitting for a while. It also makes your time visiting the storage unit facility more comfortable.
- Types of climate control. Extra Space Storage has different kinds of climate control depending on where you live, including basic climate control, air-cooled storage, heated storage, and humidity-controlled storage. Though climate-controlled units are the most common option, air-cooled storage, for example, comes in handy for people who live in states with extreme hot temperatures throughout the year.
- Preparation guide. The self-storage facility includes a helpful checklist of what to do before putting your items into a climate-controlled self-storage unit. Tips range from creating an inventory of your sensitive items to not placing your furniture directly on the ground (it protects against “unforeseen circumstances”).
- The web page helps eliminate confusion around climate control by answering some of the top questions customers ask. If you have a question, chances are someone else has the same one.
Extra Space Storage doesn’t try to sell you on climate control if you don’t need it. That kind of honesty sets it apart from some of its competitors.

Extra Space Storage gets some of the best customer reviews in the nation. Customers can’t stop talking about how helpful and friendly Extra Space Storage employees are.

Life Storage—Customer Service
Life Storage gets fantastic customer reviews. Customers like its clean storage units, professional reps, and strong security features, and we’re in love with its truck rental deals for new customers. Plus, Life Storage has five types of climate-controlled storage units to best match the climate in your area. The company’s strengths are probably enough to outweigh its high prices, but it can be challenging to find a nearby Life Storage facility (it has fewer than 1,000 locations in only 33 states).
What sets Life Storage apart?
Multiple climate-control options
Life Storage has a variety of climate-controlled storage units. The storage unit company helps you match your situation with the right storage space whether you live somewhere that’s hot, cold, humid, or dry:
- Climate-controlled storage units. Life Storage suggests that you think of its basic climate control as temperature-controlled storage. They’re cool in the summer and warm in the winter.
- Humidity-controlled storage units. Life Storage is one of the few companies to offer storage units that monitor humidity levels. These units reduce the likelihood of things like mold, mildew, and rust by preventing excess moisture. Life Storage recommends humidity-controlled storage for items such as valuable documents, furniture, and electronics.
- Heated storage units. These storage spaces receive extra attention during the winter. Not only can heated storage units extend the life of your belongings, but they make moving during the winter months tolerable. The storage spaces aren’t quite room temperature—but they’ll be much warmer than non-climate-controlled storage units.
- Air-cooled storage units. Life Storage blows air through water vapor to lower the temperature in these storage units. The company recommends air-cooled units for items that don’t do well in high temps but can handle humidity levels slightly above average (like glass, pottery, and most woods).
- Air-conditioned storage units. Think of the air-conditioning in your home. These HVAC units lower the temperature in your storage unit to protect belongings that don’t do well in the heat (like furniture, plastics, and wax).
The definition of extreme heat can vary, but most storage companies recommend using temperature-controlled storage if conditions inside the unit reach around 80–85°F.
Stellar customer service
We haven’t found a storage unit company that gets better reviews than Life Storage. It even beats out (barely) Extra Space Storage—our #1 overall company. Customers love Life Storage’s clean facilities, robust security, and friendly customer service representatives. That’s quite the hat trick.
Want excellent service and lots of options?
We give U-Haul a higher score for climate control than most customers. While people are justifiably upset with U-Haul’s poor customer service and frustrating website, the company makes up for some of its weaknesses. It has both temperature- and humidity-controlled storage units, nationwide availability, and affordable rates. U-Haul might not be the sexy choice, but it’s tough to beat low prices and hard-to-find humidity control.
What sets U-Haul Self Storage apart?
U-Haul is one of the few self-storage companies with climate control that monitors both temperature and humidity. Since moisture in the air can damage your belongings, these units are popular in high-humidity states like Florida and Alaska.
If you’re still unsure whether climate control is right for you, U-Haul has a five-question checklist to narrow your options. U-Haul recommends a climate-controlled facility if you answer yes to any of these questions:1
- Are your items of sentimental or high value to you?
- Does the temperature in your area drop below freezing?
- Does the temperature in your area rise above 90°F?
- Is there high humidity in your area throughout the year?
- Do you have a long-term need for storage?
U-Haul is known for its low prices. That’s nothing new. The company routinely gets great marks for truck rental, moving container, and traditional storage unit pricing. But it takes things to a new level when it comes to climate-controlled storage.
Move.org compared nearly 400 U-Haul quotes with more than 2,000 bids from other storage companies and found that U-Haul is about 20% cheaper than the industry average. So you’re likely to save more than $200 per year compared to the next most affordable option. That’s enough to hire movers to load and unload our storage unit for you.

CubeSmart—Lots of sizes
CubeSmart saves you money. Not only are its prices about 15% below the industry average, but the company also has nearly a dozen sizes of climate-controlled storage units. That helps you find a perfect fit, so you don’t pay for a unit that’s bigger than what you need. CubeSmart also has valuable perks ranging from video monitoring and storage unit shelving to free coffee and Wi-Fi. The main drawback is security: we couldn’t verify if CubeSmart units have alarms. They don’t talk much about security on the company website.
What sets CubeSmart apart?
Lots of climate-controlled storage unit sizes
CubeSmart has more size options for climate-controlled storage units than anyone else we’ve seen. Here’s why that matters: you essentially pay for empty space if you don’t fill your unit to the brim. And since climate control is the most expensive kind of storage, CubeSmart’s size options mean you can find the perfect fit—and put money back in your pocket.
