How to Reduce AC Costs for Self-Storage

If you’re looking to lower the cost of running your Self-Storage facility, lowering the cost of Air Conditioning can be the first big step. While this commonly used process can work for keeping out mold and mildew if done right, it can be inefficient and costly. However, there is another way to deal with moisture that can reduce AC costs at the same time.

Why Air Conditioning is So Expensive for Self-Storage Companies

One of the biggest reasons that cost of air conditioning for self-storage companies is so high is because the system is inefficient. Many storage facility owners have an expensive air conditioner trying to maintain temperature in a poorly insulated building with a lot of air infiltration. Air Conditioners spend 85% of their large energy draw on temperature but only 15% on dehumidification, which is extremely inefficient.

Dehumidifying (Latent Energy) is a byproduct of this process, but Temperature (Sensible Energy) is the main purpose of the system. Most HVAC contractors will recommend 750 Square Feet per Ton of AC because they are familiar with sizing occupied commercial spaces, not self-storage facilities that are unoccupied. Because of this, the AC does not run often enough to effectively dehumidify so operators eventually continually lower the temperature in a desperate attempt to make the AC dehumidify.  This means that your HVAC system is over-cooling the space, and that’s very expensive. In addition, the meager 1-2 pounds of water removal per kWh that the air conditioner provides are not nearly enough to keep moisture out completely.

The result is a super-cooled and humid unoccupied space generating astronomical energy bills.

A Cheaper Way to Deal with Moisture in Self-Storage Facilities

Because the space is unoccupied, instead consider under-sizing your AC units to cover up to 1500 square feet per Ton of AC instead of 750 square feet per Ton of AC. Increase your temperature inside to 80-85 degrees instead of 70 Degrees and allow the AC to address Sensible Heat alone where it is most effective

Then, instead of relying on the HVAC system to deal with moisture, consider utilizing a dedicated dehumidification system. This solution doesn’t consider moisture and mildew a secondary byproduct, it is actively working to deal with the space’s relative humidity (RH) to ensure the integrity of the stored items and your building.

Ultimately this solution will reduce your energy consumption and solve your moisture issues in one fell swoop. Instead of running heating and air conditioning constantly to deal with moisture, the dehumidifier will take care of that process completely. And that means that you can just use the HVAC system to deal with temperature where it is most effective.

Adding a Dehumidifier Could Solve All of Your Problems
