Think storage units are only for Storage Wars? Think again. Anyone can use a storage unit. Maybe you’re in the middle of a move, downsizing, making room for a new baby, storing inventory for your side hustle, or simply realizing your house is running out of room.

But here’s the thing: not everything you put in a storage unit loves sitting there through Ohio’s hot summers and freezing winters. Humidity and extreme temperatures can cause damage to certain weather-sensitive belongings, especially when they’re stored for a long time. Insert climate-controlled storage units. But which sensitive items actually need it? Let’s take a look.

What Is Climate-Controlled Storage?

The goal is pretty simple: give your belongings some extra protection from the weather outside. Climate-controlled units help keep extreme temperatures and humidity from taking a toll on your stuff, especially when it’s sitting in storage for months at a time. And while climate control doesn’t mean your storage unit is completely sealed off from the elements, it does help keep the conditions inside from getting quite as extreme as they can in a standard unit.

Start With Your Furniture

Remember Grandma’s couch? The one covered in plastic that nobody was allowed to eat on, let alone sit? Yeah, she may have been onto something. While we’re not suggesting you wrap your entire living room in plastic, we are suggesting you consider protecting your furniture from certain elements to help it last longer if you are putting it in storage.

Storing wooden furniture indoors? You want to keep it from warping, cracking, or swelling when exposed to humidity or changing temperatures, kind of like the walls in an old house. That's where a climate-controlled unit comes into play. Not into wood, but have leather furniture instead? Leather has its own issues. For instance, if exposed to too much heat over time, it can dry out or crack. One of the benefits to take away from this section? If you're storing furniture and want it to last, don't just put it in any storage unit.

Don't Forget Your Electronics

That vintage Nintendo you’ve been hanging onto move after move after move? You probably want it to work when you finally pull it back out. If not stored properly? Temperature changes can create some serious issues for your gaming system. For instance, it can cause condensation inside your Nintendo, which can lead to other issues like corrosion or damage to internal components, making it useless.

And it’s not just old gaming systems. TVs, computers, cameras, speakers, and appliances can all be affected by moisture and temperature swings. If you’re storing electronics for more than a short stretch, a temperature-controlled storage unit can give them some added protection from all of that.

Don't Let Your Memories Fade

You know that box of old photos from high school you keep meaning to go through? Or your grandma’s photo albums that you’d never dream of throwing away? Those are exactly the kinds of things you don’t want to forget about once they’re in storage. Why? Because things like paper and photographs can be surprisingly sensitive to humidity. Too much moisture can lead to mold, mildew, sticking, and curling, while overly dry conditions can leave paper brittle. Heat can also cause photos and ink to fade over time. That’s where humidity control can help.

Musical Instruments Need Care, Too

Remember that instrument you played in middle school? Maybe you still jam with friends on the weekends, or have a guitar you swear you’re going to learn someday. If it’s headed for a storage unit, give it a little thought first. Wood and humidity aren’t exactly a great combination, and temperature changes can cause wood to expand, contract, or crack. That can mean trouble for guitars, violins, cellos, pianos, drums, and other instruments. And don’t assume metal or plastic instruments are automatically fine in traditional storage either. Many still have wood, felt, pads, or other parts that can be affected by humidity.

Keep Clothing and Fabrics Protected

That wedding dress hanging in the back of your closet? You probably don’t want to open its box someday and find a musty, discolored surprise. The same goes for that vintage jacket you scored at a thrift shop years ago or the fur coat your grandma gifted you that you only pull out for special occasions. When storing clothing and certain fabrics, a lot of thought needs to go into how you store them. Picture opening that storage box a year from now and finding your favorite jacket looking and smelling exactly like you left it. That’s the goal here. However, humidity and extreme temperature changes can work against you, especially when fabrics are packed away for a long time. One easy thing you can do? Ditch the plastic and use cotton covers, breathable garment bags, or even pillowcases.

Is Climate Control Right for Your Stuff?

At the end of the day, choosing the right storage unit comes down to what you’re putting inside it. Your old lawn mower probably doesn’t need the same treatment as Grandma’s china, your wedding dress, or that Nintendo you refuse to part with.
