How To Recharge A Dehumidifier

Dehumidifiers are the best appliances to lower the humidity levels in your house. Ideal levels of humidity will help maintain the structural integrity of your home. However, there are times when the humidity levels are excess.It is also good to know how to recharge a dehumidifier.

During such times, you need to get a dehumidifier. This device will stabilize the required humidity level in your home or office.

It works by absorbing air rich in moisture from the atmosphere, passes it via multiple filters, and discharges cool and dry air back to the atmosphere.

The functionality of a dehumidifier depends on its design, and they come in various makes because of the presence of different manufactures.

Some manufacturers design dehumidifiers that rely on a compressor to achieve the appliance’s main functionality.

They use coolants or refrigerants to produce cold and dry air, which is besides dehumidifying. These designs of dehumidifiers are slightly expensive when compared to others.

The efficiency of a dehumidifier that relies on a compressor will depend on the presence of a coolant or refrigerant. Once the coolant has been consumed up, the dehumidifier may start malfunctioning.

A malfunctioning dehumidifier may produce a rattling sound or run the whole day but may not lower the humidity levels.

When this is the case, recharging your dehumidifier is the best solution. Read on to learn how to recharge a dehumidifier.

Key Indicators To Look At Before Recharging A Dehumidifier

There are three key aspects that you need to examine before you settle for recharging your appliance, they are;

  • Confirm whether the motor is working correctly or not. Before you get a coolant for your dehumidifier, the first thing to check should be running the appliance’s motor. Is the motor starting? Does it produce any extra noise like rattling?
  • If both answers are negative and you are sure that the device is connected to a power supply, the motor could be the problem. You may need to call in a certified HVAC technician.
  • Is the fan working? Check whether the fan is rotating or not. If it is rotating, is it pulling air or not? Your dehumidifier fan might stop running because it has been blocked by debris or dust. Try blowing out the dust and clearing the debris; if the fan doesn’t still run, the fan motor could be defective.
  • Check whether the environment or room you are dehumidifying has high humidity levels. A dehumidifier will not work in a room with low humidity levels. Check out the humidity levels in the house and the humidity setting level on your appliance before running the dehumidifier.

If the above aspects are not the issue behind your appliance’s malfunctions, you may now be required to recharge your dehumidifier.

The Procedure Of Recharging A Dehumidifier

Before thinking of recharging your dehumidifier, you need to know whether it is rechargeable or not. It is not all models of dehumidifiers that are rechargeable.

Rechargeable dehumidifier brands are limited to those relying on coolant or refrigerant to work. To confirm whether your dehumidifier is rechargeable or not, consider looking at the manual that came with the appliance.

In case of a missing manual, you can get assistance from the internet. Here are the steps to follow;

  • You are likely to miss recharge hits in your local hardware shops. However, you can access them online. The rechargeable kits have a small gas cylinder that carries R-22, R-401A among other gases, fueled to a dehumidifier compressor.
  • Take note of the gas or coolant you are buying, and it must be appropriate for the compressor. Inspect the dehumidifier sticker or panel to determine whether the device requires a refrigerant or coolant. Knowing the year the dehumidifier was made is an easier way of determining the appropriate coolant or refrigerant to use. Dehumidifiers built before 1995 are likely to be compatible with the R-22 coolant type. Any dehumidifiers made from 1995 onwards are considered modern, and they are compatible with R-401A in general. R-401A is also known as Puron; it is a costly coolant. Puron is more environmentally friendly than R-22. You cannot use R-401A in an old fashion dehumidifier. Similarly, you cannot use R-22 in a modern dehumidifier.
  • Loosen all the bolts on your dehumidifier to get access to the compressor. You should be careful when unbolting, know where to return each screw after recharging the compressor. Begin by removing the back or top part of the dehumidifier. If you are not conversant with unbolting your dehumidifier model, you can search for online videos that will guide you through the entire process.
  • After getting the compressor out, find a hose. Connect the gas cylinder to the hose correctly. Ensure that it is correctly fixed and press it against the compressor. At this point, you will be transferring the coolant from the gas cylinder to the compressor. Take caution when recharging your dehumidifier; most coolants are flammable. Therefore, you should do the recharging with a facemask on and do it in your backyard and ensure there is no nearby source of the fire.
  • The transferring process (recharging) may take some minutes. Usually, you will find instructions and the period it may take to recharge on the gas cylinder or can.

After the recharging process is complete, remove the gas cylinder, return the compressor and start returning every unbolted part to its position.

The dehumidifier should now be recharged and ready to reduce the humidity levels in your home. There are also many ways one can learn on how to remove humidity from a room without a dehumidifier.

If you are not comfortable with the entire recharging process, you should consider contracting a certified HVAC company to do it for you. Actually, with the dangers posed by the use of coolants or refrigerants, scientists recommend that specialists recharge dehumidifiers.


Which Types Of Dehumidifiers Requires Recharging?

There are two critical types of dehumidifiers available in the market.

  1. Condensate dehumidifiers

These dehumidifiers require recharging after a long period. Condensate dehumidifiers are also known as refrigerant dehumidifiers. It works by drawing water moisture from the atmosphere through the condensation process.

  1. Desiccant Dehumidifiers

This dehumidifier model removes water vapor from the atmosphere by using a desiccant. A desiccant is a material that quickly absorbs and retains water vapor.

It is a suitable dehumidifier model for people living in areas with low temperatures.

In most cases, desiccant dehumidifiers use silica gel. Recharging such models is easy because it is easy to know when to recharge. They operate with color beads, which change from orange to green when it is due for a recharge.

What Should You Do When Recharging Does Not Help?

Recharging your dehumidifier is one approach to keeping it at its best. However, when recharging does not change the situation, it still malfunctions.

If this happens, go through the user manual and follow the maintenance guide. If your appliance’s warranty period is still valid, contact the customer support team.

Apart from recharging, regular maintenance exercise includes;

  • Dusting off the coil, and sometimes you may also need to vacuum it.
  • Try checking whether the screws around the fan are tight.

If your attempts to restore your dehumidifier’s functionality fails, get a professional to work on it.

Final Verdict

A dehumidifier is an essential appliance to have in your home. There are both rechargeable and non-rechargeable dehumidifiers in the market, with the former being more expensive.

When using a rechargeable dehumidifier, there are several aspects that you need to consider before resolving to recharge it.

After ascertaining that your device requires a recharge, keenly follow the recharging procedure for the best results.

Take precautionary measures when recharging your dehumidifier. Remember, the coolant or refrigerant you are using may be harmful to you and even the environment.

If not sure of what you are doing, contact a certified HVAC technician to do the recharging. If you have done the recharge by yourself and the dehumidifier is not running efficiently, your device may require extra maintenance services.
