Dehumidifiers Services: Repair & Installation

Indoor air quality is determined by several indicators, one of which is humidity. Higher-than-normal humidity leads to mold, musty odors, and health issues. The solution is installing a dehumidifier, an essential device for maintaining a comfortable and healthy microclimate in your home. Like any equipment, it requires maintenance, including regular cleaning, disinfecting, and adjustments based on your needs.

If you are looking for a reliable climate control service near you, our company is always ready to help. We offer a full range of services, from dehumidifier repair to installation and regular maintenance.

How does a dehumidifier work?

A dehumidifier is a device designed to reduce humidity levels in a room by removing excess moisture from the air. This helps prevent problems such as mold, mildew, condensation, and unpleasant odors. The equipment is especially useful in areas with high humidity, such as basements, bathrooms, or kitchens. Dehumidifiers create a comfortable living environment and improve health by reducing the risk of allergies and respiratory diseases.

The main stages of dehumidifier operation

• Air intake—The fan draws air from the room and passes it through special filters that remove dust and contaminants.
• Cooling and condensation—The air passes through a cold heat exchanger (evaporator), where it is cooled below the dew point, causing moisture to condense into water droplets on the evaporator surface.  
• Condensate collection—The condensed water is collected in a special tank or discharged directly into the sewer system via a drainage hose.
• Air heating and discharge—The dehumidified air passes through the condenser, where it is heated to a comfortable temperature before being returned to the room.
• Thus, the dehumidifier continuously reduces humidity levels, providing comfortable living conditions and preventing excessive humidity and mold formation.

Types of household dehumidifiers

Home equipment is categorized into several types based on the principles of operation, design, and application:

• Condensing dehumidifiers—The most common type of household unit that cools the air, leading to moisture condensation.
• Adsorption dehumidifiers—Use an adsorption material (such as silica gel or hygroscopic material) to absorb moisture from the air.
• Thermoelectric (Peltier) dehumidifiers—Use a thermoelectric module to cool the air, resulting in moisture condensation.  
• Mixed (combined) dehumidifiers—Combine the functions of both condensation and adsorption dehumidifiers.
• Programmable (automatic) dehumidifiers—Feature smart technologies that allow you to adjust humidity levels, operating time, and other parameters via mobile applications or the control panel.
• Central dehumidification systems—Serve multiple rooms or the entire apartment, integrating into the heating, ventilation, and air conditioning (HVAC) system.

Each type of dehumidifier has its own advantages and disadvantages, so the choice depends on your specific needs, usage conditions, and budget. They are effective in high humidity.

Condensing dehumidifiers are economical to operate but can be noisy and less efficient at low temperatures. Adsorption dehumidifiers work efficiently at low temperatures and are suitable for drier conditions, but they can be more expensive than condensing dehumidifiers.

Peltier (thermoelectric) units are environmentally friendly because they use natural absorbents; however, they require regular replacement or drying of the elements. Thermodynamic dehumidifiers are quite expensive and require complex maintenance. Therefore, it is best to entrust the choice of dehumidifier type to specialists.

The most common breakdowns of dehumidifiers

• Fan problems caused by motor wear or contamination
• Compressor malfunction due to wear, overheating, or power supply issues
• Frozen evaporator resulting from fan malfunction, low room temperature, or sensor issues
• Poor system tightness caused by damaged piping or connections, which may lead to refrigerant leakage
• Humidity sensor issues that may prevent the dehumidifier from turning on or off at the correct times
• Power supply problems, such as damaged cords, sockets, or buttons that can prevent the dehumidifier from starting
• Dirty or clogged filters that reduce the dehumidifier's efficiency and airflow, potentially leading to overheating or overloading

To avoid these breakdowns, regular maintenance is essential. A dehumidifier with timely cleaned and replaced filters, along with checked fans and compressors, will last longer. However, it may sometimes be necessary to repair the dehumidifier.

Features of dehumidifier service

Depending on the type of malfunction, dehumidifier repairs involve several main stages.

• Diagnosis of the problem—the technician examines the device and checks all components, such as the fan, compressor, electronic boards, and humidity sensors, to determine the cause of the malfunction.
• Disassembly of the device—after identifying the problem, the technician disassembles the dehumidifier to access the faulty components. This may involve dismantling panels to reach the compressor, evaporator, or other internal parts.  
• Replacing or repairing components—Depending on which element is faulty, the technician can either replace it with a new component or repair it. For example, a damaged fan is replaced, while a refrigerant leak requires sealing the system and adding the necessary refrigerant.  
• Electronics and connections check—All connections, power cords, and controllers are inspected. It may be necessary to replace damaged wires or the control board.  
• Leak check—This is a mandatory step if the problem involves a refrigerant leak.
• Testing the unit—After repairs, the technician reassembles the unit and conducts tests to ensure that the dehumidifier operates properly.

Maintenance of dehumidifiers

During the repair of dehumidifiers, preventive maintenance can be performed, including cleaning the filters, evaporator, and condenser from dust and dirt. This enhances the humidifier's efficiency. Other tasks may include:

• checking the refrigerant level
• cleaning the condensate tank
• checking and cleaning the fan
• checking the humidity sensors

A general system check involves inspecting all mechanical and electrical components of the unit for damage, corrosion, or wear. Connections, cables, and other elements are also examined.
