What Not to Leave Inside of a Storage Unit in Summer | Modern Storage® Unpacked

Summer is one of the busiest seasons for the self storage industry, and it is also the season that generates the most preventable damage claims and unpleasant surprises. In this episode of Modern Storage® Unpacked, Modern Storage® breaks down exactly what you should never leave inside a storage unit once temperatures start climbing. The conversation is grounded in real-world experience from the self storage industry and serves as a practical guide for anyone renting a unit or helping a customer make smart storage decisions. The episode opens with a story that will be familiar to anyone who has worked at a storage facility long enough: a chest freezer stored in a non-climate-controlled unit over the summer, left without being cleaned out first. What happens inside a sealed freezer sitting in a unit that reaches over 100 degrees Fahrenheit is not pretty. The resulting odor, mold, and mess can damage surrounding items and make the unit nearly unusable. Modern Storage® use this as the jumping-off point for a broader conversation about how summer heat transforms an ordinary storage unit into an environment that is hostile to a wide range of everyday items. A significant portion of the episode focuses on the science behind why storage units get so hot and what that means for your belongings. Standard drive-up storage units are constructed of metal and are not insulated or temperature regulated. On a 90-degree summer day, the interior of one of these units can easily reach 130 to 150 degrees Fahrenheit. Modern Storage® explain how this kind of heat warps, melts, spoils, or otherwise destroys things that most people would never think twice about storing. The list includes obvious candidates like food and perishables, but also extends to electronics, lithium batteries, aerosol cans, candles, vinyl records, photographs, wooden furniture, instruments, medications, and certain types of artwork. The episode also addresses the refrigerator and appliance storage issue in practical terms. Many people move large appliances like chest freezers, refrigerators, and washing machines into storage during a transition period, such as a home renovation or a move. Modern Storage® walks through the correct way to prepare these appliances before storage, including defrosting, deep cleaning, drying completely, and leaving doors slightly propped open to prevent mold and mildew buildup. Skipping any one of these steps in summer heat accelerates the growth of bacteria and mold to a degree that most renters do not anticipate. Modern Storage® also make a strong case for climate-controlled storage units as the right solution for customers storing anything of value during the summer months. Climate-controlled units maintain a consistent temperature range year-round, protecting sensitive items from both summer heat and winter cold. The episode touches on how storage facility operators can better educate their customers at move-in about the risks of heat exposure, which ultimately reduces complaints, damaged goods, and difficult conversations at the front desk. The episode wraps up with actionable advice for renters heading into summer. Modern Storage® encourage listeners to do a full audit of what is currently sitting in their unit, swap to a climate-controlled space if they are storing anything irreplaceable or temperature-sensitive, and treat large appliances like the biohazards they can become when stored improperly. The tone is candid and direct throughout, making this episode a useful resource for both first-time renters and self storage industry professionals looking for customer education material.
