Mold On Air Conditioner

Why Air Conditioning can’t Control Mold in Self Storage

On the whole, Self-Storage companies tend to deal with fighting mold and mildew in the same way. They utilize an ambitious rotation of air conditioning and heating in an attempt to keep stored items from getting too damp, too dry, too hot, or too cold. But the problem with that system is that not all of the stored items will react to heating and air conditioning the same way.

For example electronic products like old VCRs and record players that are being stored for the next generation, can’t stand up to high heat, nor can they deal with an exceptionally moist atmosphere. Extended periods of time in either of these conditions can completely ruin these items. On the other hand, a couch that sits in an overly damp room will likely be smelly when pulled out of storage and could have mold on the wood frame inside.

The Theory Behind Air Conditioning as Mold Prevention

One of the main problems we have with mildew and mold in self storage in the U.S. is the continued use of air conditioning to get rid of extra air moisture. Many believe that by lowering the temperature of the room, excess moisture in the air will simply dissipate. While this is true in some cases because air conditioners will remove some moisture from their air, they don’t do this efficiently or completely without assistance from dedicated dehumidifiers. If sized incorrectly, air conditioners can actually make the air hold more moisture than they remove.

But here’s the problem: driving the temperature down actually increases Relative humidity. And that means that a colder room that has been cooled with Air Conditioning is actually going to be worse for stored items in terms of excess moisture. Items like a beautiful handmade wool rug or even an heirloom wood 19th century headboard can’t handle high amounts of moisture without proper ventilation and could grow mold and mildew in the meantime.

Climate Control vs. Heating & A/C in Self-Storage

Unlike a regimen of heating and air conditioning, climate control can ensure that all of the items are in a stable climate. With heating and air conditioning, a thermostat will turn on the A/C when it’s too hot and the heat when it’s too cold, but what happens in between can be damaging.

A climate-controlled environment, on the other hand, is a set of temperature and humidity conditions that remain static. That means that all of those stored items will be subject to the same conditions as it would if it was in a nice, dry house in a mild climate. It also means that you don’t have to worry about mold, mildew, or excessive heat exposure to electronics, linens, or wood items that are stored away.
