Between dust resistance, humidity control, and water damage prevention, climate-controlled storage units are becoming more useful—especially if you’re looking to store valuable or irreplaceable belongings.
Climate-controlled storage units protect your valuables—everything from winter clothes to artwork to that family hope chest you inherited—better than standard self-storage units can. While climate-controlled storage is generally more expensive, its ability to keep your items safe from damage or deterioration is well worth the price of admission.
Read on to see which self-storage companies we dub the best for climate-controlled storage.
#1: Extra Space Storage
With everything from top-notch security features and monthly pest and rodent prevention to discounted truck rentals and a variety of unit sizes, Extra Space Storage deserved the praised we showered on it in our best self-storage companies list—and it earns the top spot in this review, too.
Extra Space’s climate-controlled units offer the best protection for your belongings of any self-storage company we reviewed.
- Monthly pest and rodent control treatments
- Individually alarmed units
- 24-hour access
- Fewer storage locations than Public Storage
Why Extra Space is the best climate-controlled self-storage company
Reason #1: It conducts monthly rodent and pest control treatments
When you put your vinyl record collection and first-edition books in climate-controlled storage, you expect them to be safe from the elements, right?
There’s actually more to it: Rodent and pest control treatments guard against crawling critters, which can be equally as detrimental to your things as water leaks and temperature swings.
Since pest protection is an added amenity, not all self-storage companies offer the service. Even still, Extra Space offers monthly pest control treatments, making it an easy choice for our top spot.
Reason #2: It offers five-star security
Extra Space not only protects your belongings from damage; it also protects them from theft. While standout security features often warrant their own callouts, Extra Space has so many that we couldn’t decide on which ones we liked best.
Here’s the full list of amenities Extra Space Storage offers:
- Electronic gates with coded and/or keyed access
- Video surveillance
- Individual unit door alarms
- On-site managers
- Fire prevention systems
With these security protection measures in place, you can rest assured your stuff is safe from both damage inside the unit and threats from outside. Plus, while some self-storage companies offer just two or three security features, Extra Space gives you at least five—upping the ante on what it means to keep your belongings safe from theft.

#2: Public Storage
Although Extra Space snagged the number one spot on our list, Public Storage’s nationwide availability and grade A security make the company a close second.
Public Storage has the most storage space nationwide, and with more availability comes more opportunity to find the right size and type of storage unit close to where you live.
- Lots of storage unit sizes available
- First-month discounts
- No pest protection
- No 24-hour access
- No individually-alarmed units
Why we recommend Public Storage
Reason #1: It has the most locations of any self-storage company
Public Storage has more locations than any other self-storage company—which is no small feat. With over 2,000 facilities dotting the US, Public Storage makes climate-controlled storage accessible and convenient.
This means you’re more likely get the right storage unit you need in a nearby facility. And let’s face it: if a company’s closest location is three hours away from you, you likely won’t want to do business with them no matter how much their services impress you.
As with any self-storage company, services and features vary by location, but with more options to choose from, you’re more likely to snag a Public Storage climate-controlled unit for your wine collection or knock-off Jackson Pollock painting.
Reason #2: It boasts a wide variety of storage unit sizes
With over twelve storage unit sizes, Public Storage makes it easy to find a climate-controlled storage unit for everything from your coin collection to that unused TV you have laying around.
Plus, since climate-controlled storage units are already less common than standard storage units, the more storage unit sizes available, the higher the chance you’ll be able to find a climate-controlled storage unit.
Here are the most common storage unit sizes Public Storage offers:
- 5’ x 5’
- 5’ x 10’
- 5’ x 15’
- 10’ x 10’
- 10’ x 15’
- 10’ x 20’
- 10’ x 25’

CubeSmart is the most budget-friendly company on our list. With massive discounts, security features, and electrical hookups in its units (a less-than-common amenity), CubeSmart is certainly a smart way to go if you’re shopping for a climate-controlled storage unit.
At some locations, CubeSmart will even throw in a free truck rental. This perk will make hauling your things into a storage unit ten times more efficient. And if you were already planning on renting a truck to move unwieldy belongings, like that extra washer and dryer set, this discount helps cut down on costs you planned for anyway.
- Electrical capabilities in unit
- Free truck rentalsat select locations
- Discount for booking online (other discounts too)
- No pest protection
- No 24-hour access
- No individually alarmed units
Why we recommend CubeSmart
Reason #1: It has discounts galore
Since climate-controlled units are pricier than standard storage units (because someone has to pay that air conditioning or heating bill), we appreciate how budget-friendly CubeSmart is—its generous discounts will more than likely save you a few bucks.
CubeSmart also includes a free two-hour moving truck rental, which you’ll likely want anyway since you don’t want to throw your leather La-Z-Boy in the back of a friend’s pickup truck.
Here’s the full list of discounts CubeSmart offers:
- Online booking
- Active-duty military
Reason #2: It keeps your belongings secure
CubeSmart gets that you want to protect your belongings from heat, humidity, and theft. In addition to climate-controlled self-storage units, the company offers a slew of security features to keep your leather upholstery and Marvel comic book collection safe and sound.
Here’s the full list of CubeSmart’s security features:
- 24/7 video surveillance
- On-site managers
- Coded, gated entrance
While some of these features seem like no-brainers (such as 24/7 video surveillance), not all self-storage companies offer the same level of protection.
With CubeSmart, you can trust that the mahogany bookcase you’re storing is protected (both from theft and wear and tear).

With availability in all fifty states, affordable rates, and flexible move-in dates, U-Haul is a trusted, household name in self-storage—and it’s one you can trust for climate-controlled storage, too.
Plus, U-Haul makes it easy to see which of its nationwide locations offer climate-controlled storage units, eliminating the need to sift through storage options until you find climate-controlled option.
- Locations in all 50 states
- 24-hour access available at most locations
- Individually alarmed units available
- Varying customer service rating
Why we recommend U-Haul
Reason #1: It offers 24-hour access
You never know when you need to access your storage unit at odd hours.
Just as the demand for climate-controlled storage units is on the rise, so too is the case with 24-hour access storage units. In offering both amenities at most locations, U-Haul provides you with extra protection and convenience.
Having a climate-controlled storage unit raises the bar for storage protection. But 24-hour access allows you to tuck away your cello away after an evening winter performance or your DJ equipment after a late-night gig, allowing you to get full use of your storage unit bill—any time of day.
Reason #2: It has nationwide availability
Like Public Storage, U-Haul’s coast-to-coast availability ensures you’ll find a unit nearby. Keep in mind, though: you may be referred to a U-Haul partner facility, meaning it isn’t necessarily a U-Haul branded location.
Got relatives with a bad habit of showing up to your apartment with next to no notice? U-Haul’s conveniently located storage facilities make it easy to stash those boxes of books you’ve put off unpacking. (Plus, climate-controlled storage units will keep those books protected better than any ole storage unit would.)

#5. Life Storage
Don’t let Life Storage’s number five ranking fool you. Between a user-friendly website, pricing transparency, and three different types of climate-controlled storage units—the most of any company on our list—Life Storage is still a contender for the best climate-controlled storage company.
- Widest variety of climate-controlled units
- Free truck rentals at select locations
- Locations in only 28 states
- No guarantee of pest protection
- No guarantee of individually alarmed units
Why we recommend Life Storage
Reason #1: It has a variety of climate-controlled units
If you need an air-conditioned storage unit for your electronics or a humidity-controlled storage unit for your musical instruments, Life Storage offers three different climate-controlled storage unit types to choose from.
Here’s the full list of climate-controlled storage unit types Life Storage offers:
- Humidity-controlled storage units
- Heated storage units
- Air-conditioned storage units
Humidity-controlled and air-conditioned storage units are pretty standard for climate-controlled storage and help protect your clothes from getting moldy or your art pieces from warping or fraying.
Meanwhile, heated storage units can save your electronics from freezing up or your wooden furniture from cracking due to cold temperatures.
So whether you live in the desert or the tundra, Life Storage’s array of climate-controlled and temperature-controlled storage units can prevent your metal tools from rusting and your DVDs from melting.

What makes a good climate-controlled storage company?
Climate-controlled storage units, at a minimum, help keep mold and mildew out, as well as keep warm the things that need to be kept warm. Here are some additional features we suggest looking out for when choosing a climate-controlled storage company:
These security features signal that a company’s security is up to par:
- Electric gates with coded and/or keyed access: This is pretty standard for most self-storage companies and will help keep intruders out, minimizing theft.
- On-site managers: Having a property manager on hand is convenient if accidents like a flood or theft occur in your storage unit. Some locations even employ a 24-hour security guard to patrol the facility.
- Video surveillance: Having eyes on who goes in and out of your unit should be a minimum requirement for any storage facility, especially since it’ll come in handy to play back recorded video if something fishy happened.
- Individually alarmed units: Although less common, individually alarmed units fortify your unit against would-be thieves stealing your computers, sound systems, or other high price-tag items. While electric gates and video surveillance help keep intruders out of the building, individually alarmed units boost security from inside the facility, as well.
Usually, the more areas a company services, the higher that company ranks on a Move.org best list—and it’s no different here. Because climate-controlled units aren’t guaranteed at every storage location, we put a premium on nationwide availability. After all, if you must store your valuables out of sight, you don’t want them to be a forty-five minute drive away.
No matter how much you’re paying to prevent warping, water damage, or mildew, climate control can’t undo chewed-up cords or gnawed-on furniture—which is why we highly recommend companies that offer frequent pest protection. (Extra Space Storage and U-Haul are currently the only companies on our list to offer this service.)
Now that you know what to keep your eyes peeled for when looking for trustworthy climate-controlled self-storage companies, let’s recap who’s good for what:
- Extra Space Storage: Best for overall protection and facility maintenance
- Public Storage: Most locations
- CubeSmart: Best for the budget-conscious
- U-Haul: Best for nationwide availability
- Life Storage: Best for variety of climate-controlled storage unit types
Remember, climate-controlled storage units offer your valuable belongings an extra layer of protection against humidity or temperature damage. Plus, climate control combined with a decent amount of security and nationwide availability means even more assurance that your things will stay in tip-top shape while in storage.
