Storage unit climate control is a feature in self storage facilities designed to maintain consistent environmental conditions within units.

This involves regulating the temperature and, in some cases, humidity to protect stored items from extreme weather, temperature fluctuations, and moisture damage.

Climate-controlled storage units are particularly valuable for preserving sensitive or valuable items that can be damaged by extreme heat, cold, or humidity.

This feature is especially useful in regions with extreme weather, such as the hot and humid climates in Florida and Texas or the freezing climates found in Minnesota, Wisconsin, and New York.

Below are the three main features of climate-controlled units:

✅ Temperature regulation: These units generally keep temperatures within a range of 55°F to 85°F (13°C to 29°C), which helps to prevent extreme heat or freezing conditions.

✅ Humidity control: Some self storage facilities also offer humidity regulation to keep relative humidity below 50% to prevent mold, mildew, rust, or warping of the stored items.

✅ A sealed environment: Climate-controlled units are usually located indoors, providing better insulation and protection from dust, pests, and external weather conditions.

🤔 What Is the Difference Between Climate Control and Temperature Control?

Temperature-controlled units regulate temperature only, ensuring it remains within a specific range to prevent high heat or freezing.

On the other hand, climate-controlled units regulate both temperature and humidity, offering a more comprehensive solution for protecting sensitive items.

Why Do Customers Need Climate Control?

Your customers need climate-controlled units to prevent damage to their belongings, which is why it’s important to meet this demand. Here are some of the reasons why potential customers may be attracted to a climate control offering:

❄️ It keeps items in good condition

Climate control ensures your tenant’s belongings remain in good condition, regardless of external weather conditions, as extreme temperatures can damage sensitive items over time.

For example, wood furniture can warp, crack, or split in fluctuating temperatures, while leather items can dry out and crack without proper temperature control.

❄️ It avoids issues like condensation

Condensation occurs when warm, humid air meets a cool surface, resulting in moisture buildup. In a non-climate-controlled unit, condensation can develop when temperatures fluctuate.

This condensation can lead to mold and mildew growth, affecting fabric, wood, or paper items.

Condensation can also cause unpleasant odors, stains, and even structural damage to items.

❄️ It allows for storing of specialized goods

Certain items require climate control due to their sensitivity to environmental changes. Self storage tenants may need climate control to store items such as:

🎹 Musical instruments: Instruments like pianos, violins, or guitars can expand, contract, or warp with changes in temperature and humidity.

🍷 Wine collections: Wine requires specific temperature and humidity conditions to prevent spoilage and ensure proper aging.

📦 Antiques: Items like vintage furniture, books, and heirlooms can deteriorate if exposed to fluctuating conditions.

❄️ Improving the customer experience

Climate-controlled units aren’t just about protecting belongings; they also improve the customer experience.

When visiting a storage facility, especially in extreme weather, a climate-controlled environment makes accessing and organizing items more comfortable for your tenants.

For example, in summer, the temperature inside non-climate-controlled units can be unbearable, and in winter, freezing conditions can make visiting units unpleasant.

⭐️ Pro Tip: Provide the Right Advice to Your Tenants

Customers will often look to you for advice on how to best store both their special and everyday items. To meet their expectations:


  • Clearly explain storage conditions on your self storage website.

  • Offer recommendations tailored to their specific items.

  • Highlight the difference between climate and temperature control, as these terms are often confusing.

There are several good reasons to provide climate-controlled storage to your tenants. Let’s look at these in more detail below:

➡️ You can charge more and potentially upsell

Offering climate-controlled storage units enables you to charge a premium compared to standard units.

On average, climate-controlled units cost 20% to 50% more than traditional storage units, but customers are willing to pay the added cost for the protection they offer.

Customers recognize the added value of protecting their belongings from extreme temperatures, humidity, and moisture damage, making them more willing to pay higher rates for this peace of mind.

Additionally, climate-controlled units create upselling opportunities. For example, tenants considering standard storage may be persuaded to upgrade when they understand the risks to their sensitive items in non-climate-controlled conditions.

➡️ Happier customers

Customers invest in storage to keep their belongings safe and secure. Climate-controlled storage ensures that their items remain in excellent condition, regardless of external weather conditions.

This increases customer satisfaction as they can rest assured their stored goods won’t be exposed to permanent damage caused by mold, warping, or rust.

Happy customers are more likely to leave positive reviews, recommend your services to others, and become repeat customers.

➡️ Pests are kept away

Climate-controlled units are typically housed with insulated indoor structures, which have several benefits beyond temperature regulation. One of the key advantages is pest prevention.

Thicker walls, sealed doors, and improved ventilation create an environment less hospitable to pests such as rodents, insects, or termites, which can damage stored goods.

➡️ Attract more tenants

Not all customers store basic household goods; many are looking for specialized storage options for valuable, temperature-sensitive items.

By offering climate-controlled storage, you can attract a broader customer base, including businesses and individuals with high-value or fragile items.

This can set you apart from competitors offering only standard units, making it an appealing option for a wider range of storage needs.

The Downside to Providing Climate-Controlled Storage
