A climate-controlled self-storage company is one of the safest ways to store valuables without risking damage from extreme weather conditions. Unlike regular self-storage units, climate-controlled units store your belongings in a regulated environment with around-the-clock protection. This type of storage safeguards delicate items from fluctuating temperatures and humidity, helping to keep them in tip-top condition.
The top climate-controlled self-storage companies offer temperature control accuracy, monitoring systems, pest control, and security. Additionally, any company you choose to go with should have a good reputation, be conveniently located, supply a variety of unit sizes, and provide responsive and supportive customer service.

Factors to Consider When Choosing a Climate-Controlled Self-Storage Company
Before choosing the climate-controlled self-storage option for you, it’s important to consider certain factors, such as price, length of rental, unit size, and security. You may also want to take into account accessibility and cleanliness, and ask if the company offers an option to purchase insurance.
There’s no way around it — a climate-controlled storage unit will be pricey compared to a standard storage unit. Different companies will likely charge different amounts for the same or similar-sized units. We recommend getting quotes from at least two or three companies before choosing the option that’s right for you.
Length of Rental
The length of your rental also plays a decision-making role. Do you need storage space short-term or long-term? Pay attention to contracts and lease agreements, and particularly to any specifications about rental duration. It’s important to find a company with flexible options to meet your specific needs.
Most self-storage companies offer the same standard selection of storage unit sizes, from small 5-foot by 5-foot units to massive 10-foot by 25-foot units, and vehicle storage, as well. A 5-foot by 5-foot unit holds about as much as a large closet and may be best suited for storing seasonal items or small items that do not fit in your home. A 10-foot by 10-foot unit is a great choice for storing all the items in a small one-or-two bedroom apartment. And a 10-foot by 25-foot unit is recommended for a two-bedroom house or larger.
Security remains crucial when it comes to storing valuable possessions. It’s important to choose a company that not only offers a reliable security system, including cameras, padlocks, and alarm systems, but also one that maintains a reliable reputation and trustworthy employee vetting.
For most companies, the exact type of security will depend on the facility’s location or specific franchisee offerings, so check the actual facility to make sure you’re getting what’s advertised. Some companies, including CubeSmart, offer a unit-specific camera for a premium fee.
Self-storage facilities and companies offer a variety of access hours, which can depend both on geographical location and the actual placement of your unit in the building. Only a few facilities offer 24-hour access, and not all facilities within every company offer the same amount of access. Drive-up units make unloading from your car convenient, but these units are rarely climate-controlled since it is typically easier to maintain a set temperature in an interior unit.
A clean storage facility is important for the preservation of your items. While you can carefully pack your belongings into clean boxes and bags, you have no control over other tenants or the facility’s maintenance itself. A storage company that pays careful attention to cleanliness and sets strict guidelines for all tenants will keep your belongings secure and well preserved from common threats like pests or moisture.
Insurance is a must when storing valuable possessions. Choose a company that offers insurance options and make sure you understand the terms and coverage, especially if you are storing valuable items. Alternatively, many homeowner’s or renter’s insurance plans will cover your belongings up to a certain amount, even if they are stored in a facility. Check the terms of your insurance policy or talk with an agent from your insurance company for more information.
Are Climate-Controlled Storage Units Worth the Money?
Climate-controlled storage units can be worth the extra cost to store items sensitive to temperature and humidity changes, such as electronics, artwork, and important documents. Climate-controlled facilities protect these items from damage and prevent the growth of mold and mildew by keeping the unit at a consistent temperature — usually between 50 and 80 degrees Fahrenheit. However, a standard storage unit will suffice for noncritical items. It’s important to assess the specific needs of the items you’re storing to determine whether a climate-controlled unit and its additional cost are necessary.
What’s an Ideal Temperature for Storage Units?
A storage unit set between 55 and 85 degrees Fahrenheit helps protect items from damage due to extreme temperatures. This ideal range also prevents the growth of mold or mildew, which can be harmful to both the stored items and the people who come in contact with them. For precious keepsakes, like fine art and archival media, we recommend inquiring about humidity levels. Humidity levels should be kept between 30 to 50 percent to avoid moisture-related damage.
Frequently Asked Questions
Can Mold Grow in a Climate-Controlled Storage Unit?
Mold is an incredibly versatile organism and can grow in a climate-controlled storage unit if the humidity level is not properly controlled. To prevent mold growth, the humidity level in a unit must be kept within the appropriate range (30 to 50 percent humidity).
Do Storage Units Need Ventilation?
Individual storage units do not necessarily need ventilation; however, proper ventilation plays an important role in keeping climate-controlled units at an appropriate temperature. Ventilation creates air movement and helps prevent moisture from accumulating inside the unit.
What Items Should Be Stored in Climate-Controlled Storage?
Items sensitive to temperature and humidity changes, such as electronics, musical instruments, artwork, and archival documents, should be stored in a climate-controlled unit.
How Do You Store Furniture in Climate-Controlled Storage?
The best way to prepare furniture for storage is to clean and dry the item thoroughly and wrap it in a furniture pad, blanket, or shrink wrap. You can buy industrial-size rolls of shrink wrap at home improvement stores. Preparing your furniture in this way keeps moisture from damaging your items and protects them from possible harm during the moving process.
What Is the Difference Between Heated and Climate-Controlled Storage?
Heated storage units maintain a consistent heated temperature, while climate-controlled storage, ideally, maintains both a consistent temperature and humidity level. Check with the company to ensure it provides the type of climate control you’re looking for.
Is Cardboard or Plastic Better for Storage?
Both cardboard and plastic can be used for storage, but plastic containers are more durable and moisture resistant, making them a better option for long-term storage.
What Should You Not Leave in a Storage Unit?
Do not store perishable items, flammable materials, hazardous materials, and illegal items in a storage unit. Not only can this violate the terms of your storage agreement, but many of these items can also void insurance policies.
How Do You Prevent Moisture in a Storage Unit?
To prevent moisture in a storage unit, it’s important to keep the humidity level within the appropriate range (30 to 50 percent humidity), use moisture-absorbing materials, and check for leaks or water damage. You can also place desiccant packets into your storage boxes to help prevent moisture from accumulating.
How Can I Make My Storage Unit More Secure?
Properly secure your belongings by using a heavy-duty padlock on your unit and hiding any big-ticket items from immediate view. Also, make sure the company you choose has strong security measures in place, like video surveillance and keycode access.
