If you’re searching for a self storage unit, one of the first questions you’ll face is whether you need climate controlled storage. At first glance, climate control might sound like just another extra feature—but for certain items, it’s the difference between keeping them in great condition and watching them slowly warp, crack, or mold.

So, how do you know if you need it? In this guide, we’ll break down what climate controlled storage is, when it’s worth the investment, which items need it, and how to choose between climate controlled and standard units.

What Is Climate Controlled Storage?

Climate controlled storage units are designed to regulate temperature and sometimes humidity inside the unit year-round.

While exact conditions vary by facility, most climate controlled units keep temperatures between 55°F and 85°F. This range protects items from extreme cold in the winter, sweltering heat in the summer, and the damage caused by rapid temperature swings.

Some facilities also include humidity control, which helps prevent mold, mildew, and corrosion—especially in regions with high moisture levels. Check out this humidity map to see where your state ranks.

Why Does Temperature and Humidity Matter for Storage?

When items are stored for weeks, months, or years, the environment around them can cause significant wear and tear.

• Heat can cause warping, melting, fading, and breakdown of adhesives.

• Cold can make certain materials brittle or cause them to crack.

• Humidity fuels mold growth, rust, and wood swelling.

• Dry air can make leather crack and paper brittle.

If you live in a region with seasonal temperature swings or high humidity, a standard storage unit may not offer enough protection.

When Climate Controlled Storage Is Worth It

While climate control does cost more than standard storage, it’s often worth the investment if:

1. You’re Storing Sensitive Items
   Some items simply can’t withstand uncontrolled environments. If you’re storing antiques, electronics, or important documents, climate control helps preserve them for the long term.

2. You’re in an Area with Extreme Weather
   In areas where temperatures routinely dip below freezing or soar above 90°F—or where humidity stays high year-round—climate control can prevent heat, cold, and moisture damage.

3. You’re Storing Items for a Long Time
   If you plan to keep items in storage for six months or more, climate control reduces the risk of deterioration over time.

4. Your Items Will Be Stored on an Upper or Lower Floor
   In multi-story storage buildings, top floors may get warmer in the summer and ground floors may be more humid. Climate control helps even things out.

Items That Benefit Most from Climate Controlled Storage

Here’s a breakdown of the types of belongings that should be in climate controlled storage:

• Wood Furniture – Prevents warping, cracking, and splitting from humidity changes.

• Leather Goods – Keeps leather from drying out, cracking, or growing mold.

• Electronics – Protects against corrosion, condensation, and heat damage.

• Musical Instruments – Maintains tuning stability and prevents wood swelling.

• Artwork & Photographs – Stops fading, discoloration, and mold growth.

• Important Documents – Keeps paper crisp and prevents ink smudging.

• Clothing & Fabrics – Prevents mold, mildew, and insect damage.

• Mattresses & Bedding – Protects from moisture and pests.

• Collectibles – Preserves value by preventing warping, corrosion, or fading.

• Medical Supplies – Many require stable temperatures to remain effective.

Items That Usually Don’t Require Climate Control

If you’re storing these, a standard unit may be fine:

• Plastic outdoor furniture

• Gardening tools

• Vehicles (unless long-term or collectible)

• Building materials like lumber or tile

• Sports equipment made of metal or plastic

• Non-sensitive household goods

That said—if you’re unsure, err on the side of climate control. The small extra cost may be worth the peace of mind.

The Cost Difference: Climate Controlled vs. Standard Storage

On average, climate controlled units cost 20–50% more than standard units of the same size.

For example:

• Standard 10x10 unit: $90–$120/month

• Climate controlled 10x10 unit: $120–$180/month

While that difference can add up over time, think about the cost of replacing damaged items. A warped guitar, ruined sofa, or mold-covered photo album may be worth far more than the monthly fee.

Standard storage is far more cost effective, but may not be right depending on what you are looking to store.

You'll also want to factor in how much time you'll need storage. Generally, climate controlled storage is for the long-term whereas standard storage is for a much shorter timeframe.

How to Decide If You Need Climate Controlled Storage

Here’s a quick decision checklist:

1. What’s the climate like where you’re storing?

   • Hot summers? Cold winters? High humidity?
     → Climate control likely worth it.

2. How long will your items be stored?

   • Less than 3 months: You might be fine with standard storage (unless you’re in extreme conditions).

   • More than 3 months: Climate control is safer.

3. What type of items are you storing?

   • Sensitive, valuable, or irreplaceable items → Go with climate control.

4. Is the unit inside or outside?

   • Interior units with climate control tend to be more consistent in temperature and humidity.

Other Benefits of Climate Controlled Units

• Cleaner Environment – Indoor climate controlled units often have better air filtration, reducing dust and airborne particles.

• Pest Prevention – Sealed buildings are harder for rodents and insects to get into.

• Comfort for You – Loading or unloading in a temperature-controlled space is far more comfortable in extreme weather.
