7 Maintenance Tips for Dehumidifiers

How to Perform Maintenance on Dehumidifiers

Just like any 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 have a high consumption of electricity, being twice the one of a normal refrigerator. The value can be of up to ten percent of the whole electricity bill. If you want to maintain your device at maximum performance and efficiency, there are ways to do this and save on your electricity bills.

1. Keep the Machine Away from Walls

The first thing you can do is to keep a distance of at least six inches from any wall, for ensuring a good flow of air (intake and exhaust). A good airflow is recommended for a 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 measure to take is keeping windows and doors closed as much as possible in the area where the device functions. If you let them open for a longer time, the device can absorb moisture from the outside and take it indoors.

2. Properly Adjust the Humidistat

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

3. The Filter Must Be Washed or Replaced Whenever It 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 must be washed or replaced one a year. But, every manufacturer has its own schedule for this. All you have to do is check these recommendations and follow them accordingly.

4. Clean the Tank Once in a While

Emptying a tank is not the same thing with cleaning it. You must not let the tank become the proper environment for mildew or mold. When mildew and mold thrive in a tank, the tank 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 disinfectant. A monthly cleaning of the tank should be sufficient. If there is a drain hose involved, it should be verified on a monthly basis, for avoiding and blockages.

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. 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. For avoiding such a case, you need to maintain higher room temperatures. For people who cannot do this, the alternative is acquiring machines that have the 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 longer time. They should be checked and cleaned from time to time, in order to avoid debris accumulation. A vacuum brush can be used for cleaning.
