Affordable Climate-Controlled Storage Units in Carbondale, IL
When you need to protect your belongings from Carbondale’s changing weather, climate-controlled storage is the smartest choice. At Marion Self Storage, we offer affordable, secure, and hassle-free climate-controlled units designed to keep your valuables in perfect condition year-round. From furniture and electronics to business inventory or collectibles, our temperature-regulated units provide the ideal environment for long-term protection.
Why Choose Climate-Controlled Storage?
Southern Illinois weather can be unpredictable—hot, humid summers and cold winters can quickly damage sensitive items stored in garages or sheds. A climate-controlled storage unit keeps your belongings safe from temperature swings and moisture, preserving their quality over time.
Our Carbondale-area facility is equipped with indoor, temperature-regulated units that maintain consistent conditions, typically between 55°F and 80°F. These spaces protect against mold, mildew, warping, and cracking—problems that can easily affect wood, leather, paper, electronics, and fabrics stored in traditional non-climate units.
If you want your items to stay as clean and safe as the day you packed them, climate control is the way to go.

What to Store in a Climate-Controlled Unit
Not everything needs temperature control—but certain valuables do. Our customers commonly use climate-controlled storage for:
- Wooden or leather furniture
- Electronics and appliances
- Photographs, books, and documents
- Artwork and musical instruments
- Business records, files, and merchandise
- Clothing, linens, and mattresses
- Collectibles and antiques
No matter what you’re storing, a stable environment ensures your items remain protected from humidity, dust, and extreme temperature changes.
Advanced Security You Can Trust
When it comes to storage, security is everything. Our climate-controlled units are located inside a fully fenced, gated facility with modern video surveillance systems monitoring activity 24/7. Every corner of the property is covered by digital cameras and bright lighting to enhance visibility and deter unwanted access.
Entry to the facility is controlled by an automatic gate system, and each customer receives a personalized access code. This combination of physical barriers and electronic security gives you peace of mind knowing your belongings are safe day and night.
24/7 Access for Total Convenience
We know that your schedule doesn’t always fit inside business hours. That’s why our facility provides 24/7 gated access to all units—including our climate-controlled spaces. Whether you need to drop something off late at night or retrieve items early in the morning, your storage unit is always available.
With your personal gate code, you can come and go anytime without waiting for staff. It’s storage designed to be truly hassle-free and built around your convenience.
Concrete Drives and Easy Access
Unlike facilities with gravel or dirt lanes, Marion Self Storage features smooth concrete drives that make loading and unloading simple in any weather. Wide aisles provide plenty of room for moving trucks or trailers, while paved surfaces keep your belongings—and your shoes—clean.
The combination of climate-controlled interiors and concrete access lanes means you can store or retrieve items safely and comfortably, rain or shine.
Affordable Rates and Flexible Leasing
High quality doesn’t have to mean high prices. We believe everyone deserves affordable, secure storage—so our climate-controlled units are priced competitively with flexible month-to-month rental options. You only pay for the space and time you need, with no long-term commitments or hidden fees.
Our online reservation system makes it easy to check unit sizes, compare prices, and reserve your space in minutes. You can even manage your account or payments right from your phone. It’s fast, transparent, and designed for convenience.
Perfect for Personal or Business Storage
Climate-controlled storage isn’t just for homeowners. Local business owners in Carbondale rely on our facility for safe, temperature-stable storage of:
- Retail inventory and seasonal merchandise
- Documents and records that require protection
