The best climate-controlled self-storage companies provide a safe and effective method of safekeeping personal and business possessions. Unlike standard self-storage options that don’t include conditioned air, climate-controlled units are kept between 55°F and 80°F and are often located indoors. Conditioned air allows consumers to safely store valuable items and belongings that could suffer damage if exposed to large temperature fluctuations. 

Heat, cold, and humidity are three key factors that can affect the stability and lifespan of any item you choose to store. Whether it be vintage furniture with delicate upholstery, paintings, film, and even some books, choosing a climate-controlled storage unit will ensure the longevity and safety of all your keepsakes. 

To be counted among the best climate-controlled self-storage facilities, a company must provide several services focused on security, physical protection from weather, ease of use, and easy customer access. Additionally, each must be able to supply convenient locations and availability of various-sized storage units at a reasonable price.

During business hours, each site has employees on staff. The company’s staff will even accept package deliveries on your behalf.

  • 24/7 Access? Some locations

  • Widely available with over 2,700 storage facilities

  • Open seven days a week for access to belongings

  • Company offers discount rates and deals often

Cons
  • Prices are higher than many of its competitors

  • Not available in all states

Why It Made the List 

As the largest self-storage company on the planet, it’s no surprise that Public Storage is our pick for the climate-controlled self-storage company with the most locations. It’s available in 41 states across the U.S., and in case you are looking for international storage options, Public Storage also operates in Belgium, Denmark, France, Germany, Sweden, The Netherlands, and the United Kingdom. 

Public Storage offers storage solutions for almost any situation. Climate-controlled units are accessible between 6 a.m. and 9 p.m. any day at most locations and 24/7 at others. Although monthly prices to store your belongings at Public Storage are higher than many of its competitors, reports of low availability persist, proving that the company is doing something right to warrant its premium pricing. 

Expect to pay $100 on the low end for a small unit and $310 for larger climate-controlled spaces. Insuring your items is a must at Public Storage. You're good to go if your homeowner’s insurance policy covers stored items. If not, the company is happy to offer reasonably priced policies to protect your belongings.

Best Customer Service: Life Storage

Key Specs

  • Nationwide Availability: 37 states
  • Security Features: Video surveillance, electronic gate access, unit locks
  • 24/7 Access? Some locations

Pros & Cons 

Pros
  • Moving trucks are available at some facilities

  • Open late every evening for extended access

  • Online virtual storage estimator available on website

Cons
  • Individual unit alarms appear unavailable

  • Higher monthly prices than competitors

Why It Made the List 

To stand above the crowd, a company in the storage game must exceed typical expectations. Life Storage appears to have figured this out and is a customer service leader in the industry. Consistently rated above 4 out of 5 stars on numerous consumer review platforms, Life Storage has an A+ score from the Better Business Bureau. Such a rating comes as a result of a 100% response rate for complaints, which is relatively rare for most companies. The service also offers contact-free storage rentals, where customers can rent their units quickly and easily online. 

Life Storage is available in 37 states across the country and generally keeps hours between 6 a.m. and 10 p.m., which works well for those who need late evening access. Select locations offer 24/7 access as well. A unique perk for those choosing to store their goods at some of the company’s locations is access to an on-site moving truck rental, which eliminates the need to outsource a truck rental to move your items to and from your storage unit. 

Excellent customer service and convenience come at a price, though. Life Storage charges the highest monthly rates among competitors in our review. Average storage prices linger over $200 per month for a mid-sized space. We couldn't determine from the company information whether or not each storage facility includes individual unit alarms, which is standard for most storage companies.

Most Cost-Effective: CubeSmart

Key Specs

  • Nationwide Availability: 37 states
  • Security Features: Staff on-site, optional video surveillance, electronic gate access, unit alarms
  • 24/7 Access? No

Pros & Cons 

Pros
  • College student and military member discounts available

  • Wallet-friendly pricing for most units

  • Office spaces available for lease

Cons
  • Strict 30-day grace period for late payments before lockout and auction

Why It Made the List 

With about 1,200 locations in just 37 states, if you’re fortunate enough to live near a CubeSmart storage facility, you could save good money on your storage needs. Besides offering rates consistently below those of its competitors, CubeSmart also provides a steady stream of introductory rates on select storage units as well as discounts for college students and military personnel. Additionally, they host promotions for first-time storage renters, ranging from an up to 35%-off deal for a minimum four-month stay to $25 off for referring a friend.

CubeSmart’s office hours are from 9:30 a.m. to 6 p.m. during the week, and you can access your stored items from 6 a.m. to 10 p.m. any day of the week. On-site staff will be happy to accept package deliveries on your behalf, and the company can provide mandatory third-party insurance if your homeowner’s or renter’s policy doesn’t provide adequate protection. 

Storage companies typically offer a 30- to 90-day grace period to catch up on late payments. CubeSmart’s policy requires payment no later than 30 days past due before the staff will lock your unit and begin the process of auctioning your former possessions.

Best for Seniors: U-Haul

U-Haul

U-Haul

Key Specs

  • Nationwide Availability: 50 states
  • Security Features: Staff on-site, video surveillance, secure building access, electronic gate access, unit alarms
  • 24/7 Access? Yes

Pros & Cons 

Pros
  • 24/7 storage access available at most locations

  • Americans with Disabilities Act-compliant facilities

  • Locations available in all 50 states

Cons
  • Company insurance doesn’t cover several popular items

  • Experiences low customer service ratings on several review platforms

Why It Made the List 

Available in all 50 states, U-Haul has thousands of moving truck and trailer rental locations. Many of these facilities also offer climate-controlled self-storage solutions with 24/7 access, plus they're ADA-compliant (Americans with Disabilities Act). U-Haul hosts an online marketplace called Moving Help that can provide senior citizens (or anyone else) with extra packing and moving assistance. The Moving Help marketplace connects customers to local moving companies; you’ll be able to sort your results by a company’s ratings, price, and services offered. They move according to your schedule, allowing you to reserve them for as long as you need them, right when you need them. 

U-Haul’s climate-controlled storage pricing falls below the industry average of $190 per month for a mid-sized unit in a secure facility. Additionally, the company’s storage insurance policy is available at excellent rates. However, the policy has some important exceptions and doesn’t cover some popularly stored items such as artwork, antiques, documents, or motorized vehicles. 

Customer service isn’t the company’s strong point. U-Haul has struggled with low consumer ratings on popular review platforms for several years. However, U-Haul remains a solid choice for those seeking function over service.

Best Additional Services: Compass Self Storage

Key Specs

  • Nationwide Availability: 14 states
  • Security Features: Staff on-site, electronic gate access, 24-hour video surveillance

  • Moving truck rentals available at some locations

Cons
  • Facilities only available in 14 eastern states

Why It Made the List 

Living in the eastern half of the country has its perks, with access to a nearby Compass Self Storage facility being one of them. The little storage company that can, keeps up with more prominent names in the storage industry by providing excellent customer service and placing its facilities conveniently within cities and suburbs. 

Compass Self Storage goes a step further by providing additional services that larger companies may overlook. Many—but not all—locations provide 24/7 customer access, and the ones that aren’t open all the time have varied hours but generally allow access until late in the evening for convenience. The company’s personal storage concierge service sets Compass above its competitors and can be used to help you rent an on-site moving truck and access moving supplies, plus almost any other storage-related items you may need. Concierge services can even help arrange moving details for your possessions. 

Final Verdict

From a self-storage standpoint, there are few areas in which Extra Space Storage doesn’t excel. The company sets itself apart by offering all of the amenities you’d expect of a large storage company bent on effectively providing its customers with everything they need to successfully safeguard their possessions.

Extra Space Storage also allows its customers freedom of choice. You’re welcome to use your own homeowner’s or renter’s insurance policy or purchase one of the company’s options. Choose from numerous locations with several storage unit sizes available and use your own lock to keep your items safe if you choose, or purchase one of its disc locks for added protection.

How to Choose the Best Climate-Controlled Self-Storage Company 

There are many reasons to choose a climate-controlled self-storage solution. Perhaps you’re remodeling or building an addition to your home and need to store furniture or valuables temporarily. Whatever the reason, choosing the best storage facility for your needs comes down to a handful of considerations.

Facility Location

Storage facilities are available in many sizes and locations. Where you put your stuff matters, especially if you’re storing items that you’ll need to access occasionally. However, there’s more to the story. Easily getting in and out of the facility is crucial. In some cases, you may need to drag a trailer or drive a moving truck into the facility. When choosing a storage facility, consider not only where your belongings are in terms of the distance from your home, but also the obstacles that you must maneuver through and around to get there as well. Decide if it’s worth your time to have storage outside busy city areas in exchange for easy street access. 

Storage Unit Size and Availability

From a cost standpoint, renting one large storage unit is typically more beneficial than several smaller ones. Depending on the volume of items you need to store, it may be worth taking the extra step to locate a self-storage facility that has the unit size that you need available. Another consideration might be that you have items that require a climate-controlled storage environment and others that don’t. It may make sense to only rent a small unit for sensitive items and a larger one for everything else. 

Ease of Use and Convenience

We mentioned above at least one self-storage company that ensures its facilities are ADA compliant. There’s no question that facilities rated as such can provide easy access. Regardless of a facility’s compliance with ADA, easy-to-reach and load storage is crucial if you have especially heavy or bulky items or require access to your belongings regularly. 

Also, check both the operating office hours to ensure you can reach company personnel and understand the hours you can access your storage unit. Oftentimes, climate-controlled storage units are contained within a secure building with limited access. However, some facilities offer 24/7 or extended-hour access. Check that the company you choose has hours that work with your schedule. 

Additionally, consider the length of the rental contract. Most companies offer simple month-to-month agreements, but some may provide discounts or other benefits for signing on for a longer term. 

Security and Insurance

All climate-controlled self-storage companies place the security of your possessions at the top of the list of importance. It simply wouldn’t make sense to put your goods where you'd worry about their well-being. However, some facilities go the extra mile to ensure your belongings are safe. To find the best self-storage companies, seek facilities that provide on-site staffing, video surveillance, individual unit alarms, environmental protections like fire alarms and sprinkler systems, and controlled building or grounds access points. 

If you choose to purchase storage insurance from the company you’re renting from or from a third-party affiliate, be sure to purchase adequate monetary protection and choose a policy that covers the type of items you’re storing.

Pricing and Amenities

In the real world, climate-controlled self-storage isn’t very useful if it doesn’t fit your budget. In fact, not paying the storage facility on time can have severe consequences, including the forfeiture of your possessions. 

Storage pricing can fluctuate dramatically depending on your area’s demand and location. A facility located far from town can cost significantly less than a more convenient one in your neighborhood. Also, facility amenities vary widely from one company to the next. Balance your choice of storage facility between price, convenience, and the level of service you desire. 

What Is the Rental Process for a Climate-Controlled Self-Storage Unit?

Renting a climate-controlled self-storage unit starts with deciding what items and how many of them you need to place into storage. 

Make an Inventory

The reasons you’re considering putting items in storage are likely heavily influenced by the types of belongings you need to store. Moving to a new residence is an often cited reason to obtain a temporary storage solution while you downsize to stage your home for selling or need to set things aside for a while to simplify the transition. Whatever your storage needs, decide how much you need to get out of your way and make a list of the items. Although a list isn’t mandatory, it may help with an insurance claim if something goes wrong while storing your belongings. 

Decide Which Services and Amenities You Want

The items you choose to store will dictate the type of storage amenities you need. You may need a large storage unit to store large or bulky items. Delicate or valuable items or electronics are sure to require climate-controlled storage. Perhaps you’d like help moving your belongings or need late-night access to your stuff. Make a list of the features you need your storage facility to provide. 

Contact and Choose a Facility

Once you know what you’ll store and how you need to store it, hop online and start investigating facilities near you. Flip through each company’s website until you find more than one that offers the amenities you need in a price range you can handle and is conveniently located. Checking consumer ratings and reviews is an excellent idea as well. 

Reserve Your Storage Unit

The final step before moving your items into storage is to contact at least a couple of nearby facilities to inquire about specific pricing and availability. Choose the one that fits your needs best, reserve a unit, sign your contract, and you can begin placing your belongings in the space. 

What Types of Items Should Be Stored in a Climate-Controlled Unit?

As a general rule, any items that could suffer damage from temperature extremes should be stored in a climate-controlled storage space. Automobiles, tools, fabric clothing, and some seasonal items aren’t likely to require temperature controls for safe storage—think of items you might keep in your uninsulated attic space. Items that require temperature control for safekeeping include irreplaceable or valuable possessions or belongings that don’t withstand well under very high and low temperatures or a fluctuating temperatures.

  • Antiques or collectibles
  • Electronics
  • Photos and film
  • Musical instruments
  • Artwork
  • Wooden, fabric, or valuable furniture
  • Leather (especially on clothing or furniture)
  • Wine
  • Printed materials
  • Appliances
  • Personal items such as makeup or medical supplies

Frequently Asked Questions

  • What does self storage mean?

    Self storage means that you rent a location, typically at a storage facility, in which you can place personal or business items for short- or long-term safekeeping. There are two types of facility storage: full-service storage and self-service storage. Full-service storage means the company will pick up your items that require storage, securely store them, and deliver them to you when you desire. Self-service storage allows you the ability to fill your storage space on your own and access your possessions at will. 

  • How far in advance do you need to book a storage unit?

    Self-storage is often in high demand. Plan on contacting and booking your storage unit a few weeks in advance if they don’t provide availability information on the website. Availability can come into play during times of peak demand. However, self-storage units are typically rented with month-to-month contracts, meaning new ones often become available. Many self-storage facilities allow day-of reservations when units are available.  

  • What fees are associated with renting a climate-controlled self-storage unit?

    Several fees associated with renting a climate-controlled self-storage unit require consideration before signing a contract. Although most facilities won’t ask for a damage deposit, administration fees could be a one-time payment or a small monthly charge, in addition to the cost of your rental space. Other costs often include purchasing insurance from the storage company if the facility doesn’t accept your homeowners or renter’s policy coverage and buying a lock for your unit. 

  • Is insurance included when you rent a climate-controlled self-storage unit?

    Most rental storage facilities require insurance. While it isn’t typically included in the price of your climate-controlled self-storage unit, in most cases, proof of homeowner’s or renter’s insurance that states coverage for stored items is acceptable as adequate insurance at many facilities. Almost all self-storage companies offer in-house or third-party insurance policies if your homeowner’s or renter’s policy doesn’t include stored items. A small number of storage companies don’t accept outside policies and require you to purchase a policy through the facility.  

  • Are climate-controlled storage units worth the money?

    If you need storage for valuable or irreplaceable items, plan to use your storage space for electronics, or will store other things that will experience damage if exposed to extremely high and low temperatures, climate-controlled storage is well worth the added expense over unconditioned storage space. 

  • What’s the price difference between a climate-controlled and non climate-controlled storage unit?

    The price difference between a climate-controlled and non-climate-controlled storage unit can depend on your location, availability, and current demand. Expect to pay 20% more on average for conditioned storage over unconditioned. However, the percentage can vary from 10% to as much as 50%. 

  • Can food be stored in a climate-controlled storage unit?

    Some locations and companies allow certain types of food storage in climate-controlled units. However, the facility you choose will likely have rules that govern the practice. Storing perishable items isn’t allowed for the most part, with a few exceptions. Some facilities will allow you to keep somewhat perishable food, such as grains or dehydrated food, provided it’s contained in a sealed, air-tight vessel. Many more storage facilities will allow you to store nonperishable food items in climate-controlled units. If you require food storage, be sure to check with your facility before renting a space. 

  • What size storage unit will fit a car?

    The minimum size of storage unit you’ll need to fit a compact car measures 10 feet by 15 feet. However, many automobiles and personal trucks extend well beyond 15 feet in length. In that case, a 10-foot by 20-foot or larger storage space will be necessary.  

  • What type of security should climate-controlled self-storage units have?

    At the very least, climate-controlled self-storage units should be enclosed behind security fencing with electronic access to only allow customers into the facility. The best storage facilities provide excellent security protections that may include:

    • Security cameras and video recording
    • On-duty security staff
    • Lighting and motion detections
    • Keypad or other electronic gate access
    • Storage unit alarms
    • Electronic locks
