7 Maintenance Tips for Dehumidifiers

How to Perform Maintenance on Dehumidifiers

Just like any other electronic device that people use in their homes, dehumidifiers require maintenance once in a while. Even if the appliances seem to function properly, they still need special care.

Many dehumidifiers consume a high amount of electricity, perhaps even twice that of a normal refrigerator. The value of this can be of up to ten percent of your entire electricity bill. If you want to maintain your device at maximum performance and efficiency and save on your electricity bills, there are ways to do so.

1. Keep the Machine Away from Walls

The first thing you can do is to keep a dehumidifier at least six inches from any wall, to ensure a good flow of air (both intake and exhaust). Good airflow is recommended for the maximum efficiency of a dehumidifier. If there is something obstructing the airflow, the machine could be working on low performance and could end up overheating. Another important point is to keep windows and doors closed as much as possible, in the area where the device functions. If you leave them open for too long while the device is working, it can absorb moisture from outside.

2. Properly Adjust the Humidistat

If you set the humidistat too low, the device will function continuously and extract all the moisture from the air. However, this is not necessary. It is enough for the device to extract only fifty percent of the humidity and generally, the air will feel comfortable at this setting. Too low a setting can make the air dry, as well as have the machine work hard for extended periods of time. In order to check the humidity level of the air in your rooms, you should acquire a hygrometer.

3. The Filter must be Washed or Replaced Whenever is Required

The majority of dehumidifiers include filters that are meant for reducing dust and allergens. When they are dirty, these filters must be washed (if they are washable), or replaced (if they are made for one time use). In general, filters should be washed or replaced once a year. But every manufacturer has their own recommendations for this. All you have to do is check the manual and follow the instructions accordingly.

4. Clean the Tank Once in a While

Emptying a tank is not the same thing as cleaning it. You must not let the tank become the perfect environment for mildew or mold. When mildew and mold thrive in a tank, it can be the source of mildew and mold in your air. Ironically, the device that is meant for keeping the air free of mildew and mold will become the one that generates these two agents.

Such a situation can be avoided by using soap, water and a light disinfectant. Monthly cleaning of the tank should be sufficient. If there is a drain hose involved, it should be checked on a monthly basis, in order to avoid blockages from occuring.

5. Avoid Frying the Compressor

If you want to make sure you are not burning the compressor, you have to leave ten minutes of pause after you turn the device off. These ten minutes are meant for cooling the machine and for re-balancing the pressure inside it. Then, you can turn it on again without any problems. If you are not respecting this ten minutes pause, the compressor can overheat, or it can trip the circuit.

6. Look for Ice or Frost in the Condenser Coils

When the machine is used in cooler environments (below 60 degrees Fahrenheit), ice and frost can build up in the condenser coils. The efficiency of the components is affected in this case. To avoid this, you need to maintain higher room temperatures. For people who cannot do this, the alternative is to look for machines that have an auto-defrost function.

7. Clean the Exhaust Grills and the Air Intake

The air intake and the exhaust grills can become full of debris after a long time. They should be checked and cleaned from time to time, in order to avoid the accumulation of debris. A vacuum brush can be used for cleaning these out.
