The Ultimate Guide to Maintaining Commercial Dehumidifiers

In both residential and commercial spaces, maintaining optimal humidity levels is essentials for comfort, health, and property preservation. Dehumidifiers play a crucial role in achieving and maintaining these levels. However, like any appliance, dehumidifiers require regular maintenance to ensure that they can continue to operate efficiently and effectively. In this ultimate guide, we’ll explore the importance of dehumidifier maintenance and provide practical tips for keeping your unit in top condition.

Why Dehumidifier Maintenance is Important?

Excess humidity can lead to a host of problems, including mold growth, musty odors, structural damage, and health issues. A well-maintained dehumidifier helps mitigate these risks by removing excess moisture from the air. Regular maintenance ensures that your dehumidifier operates at peak efficiency, saving energy and reducing wear and tear on the unit.

Commercial Dehumidifier Maintenance Tips

Read the user manual and follow manufacturer recommendations. Familiarize yourself with the unique features and requirements of your particular unit in order to care for its specific needs.

Tip 1: Set up your dehumidifier properly. Make sure your unit is placed on a level surface and that there are no obstructions to its air intake. Blocked air intakes can cause the units to overheat and lead to increased fire hazard risk or premature failure.


Tip 2: Check water levels daily. Nearly all units that collect condensate in a reservoir shut off when their water containers are full. However, if they are not emptied, the dehumidifier stops operating and your home humidity levels will begin to rise. In addition to this, water left sitting in the reservoir for long periods of time increases the risk of mold growth – which is exactly the sort of thing a dehumidifier is meant to control. For units that feature a hose option for drainage, check regularly to make sure water is draining properly.


Tip 3: Ensure there are no kinks or blockages in the line.


Tip 4: Clean the water reservoir / condensate bucket regularly. You need to periodically clean the water reservoir to prevent mold/microbe growth. As something that is continually exposed to moisture, the potential for microbes is high. You can clean the reservoir with mold remover.


Tip 5: Never store gas or other flammable liquids near your dehumidifier. This is a major fire hazard.


Tip 6: Inspect power cords and replace when necessary. Make sure that the electrical cord you get is the same type and amperage. Never use a unit with a damaged power cord. While any electrical appliance can be a potential fire hazard, dehumidifiers tend to have a higher wattage and amperage, increasing risk of fire or shock when the cord is damaged.


Tip 7: Regularly replace any filters. If your unit has any kind of filter, make sure to check it regularly and replace yearly or as necessary. Some are simple screens that can be rinsed while larger units use filters similar to an HVAC filter (which need to be replaced every 6-12 months).


Tip 8: Inspect and clean dehumidifier’s coils once per year. Coils should be free of dust. Clean them with a vacuum cleaner or a soft-bristle brush (not a wire one, since coils are typically constructed of softer metals, like aluminum or copper, and can be easily damaged). Coils should never be wet. When temperatures are cool under 60° Fahrenheit, make sure the coils are not icing up (Most dehumidifiers have an auto defrost/de-icer to eliminate this).


Tip 9: Do not turn unit off and on quickly. Wait at least ten minutes after you turn the unit off in order to turn it on again. You will avoid short-circuiting the unit and prolong its life.


Tip 10: Apply oil to motor as necessary and check pumps intermittently. This mainly applies to larger basement/crawlspace/industrial dehumidifiers, but is important nonetheless.


Tip 11: Do not get touch pad wet when cleaning the exterior of your unit. Generally, you want to keep moisture away from the control panel. Simply clean with a dry microfiber cloth.


These above tips much take care of your annual dehumidifier maintenance! They can ensure your commercial dehumidifier stays in optimal condition, ready to efficiently manage humidity levels whenever you need it. Proper maintenance not only prolongs the life of your dehumidifier but also ensures it operates effectively, providing a comfortable and healthy environment for your space.
