Haier air conditioners are popular appliances, but they can be tricky to clean and maintain. While some basic cleaning can be done at home, such as wiping down the exterior and cleaning or replacing the filter, more complex issues may require professional servicing. This is especially true for older models, where taking off the back panel to clean the air vents, for example, could result in a loud, high-pitched noise when the AC is turned on. Haier recommends that outdoor units be cleaned by a professional Heating and Air Service and/or cleaning company.

What You'll Learn

Cleaning the water reservoir
To clean the water reservoir of your Haier AC unit, first, unplug the unit. If your AC unit is in Cool mode, it shouldn't require you to empty the water tank. This is because the unit is designed to continuously evaporate the water when in use. However, if your AC unit is in Heat mode, you may need to empty the tank occasionally. Place a shallow pan below the lower drain on the back of the unit. You can tilt the unit slightly if it helps. Remove the drain plug and drain the water completely. Re-insert the drain plug.
Next, you will want to clean the water reservoir. Wash the reservoir with dish soap and water. Wipe it dry with a cloth before reinstalling it. Make sure there is no soap residue on the reservoir.

Removing the back panel
To remove the back panel of your Haier AC unit, you will need to first locate the back panel and identify any screws or fasteners that are holding it in place. Once you have done this, you can proceed to the next step.
Using a screwdriver or the appropriate tool, carefully unscrew and remove any screws or fasteners that are securing the back panel to the unit. Make sure to keep the screws in a safe place so you can easily find them when it's time to put the panel back on.
Now, you should be able to gently lift or slide the back panel away from the unit. If it seems like it's stuck, double-check that you have removed all the screws and fasteners. Be careful not to use excessive force, as you could damage the unit or the panel.
Once the back panel is removed, set it aside in a safe place where it won't be accidentally knocked over or damaged. You can now access the internal components of your AC unit for cleaning or maintenance.
Remember, if you feel uncomfortable or unsure about any part of this process, it's best to consult a professional or refer to the user manual for more detailed instructions specific to your model.

Cleaning the air vents
To clean the air vents of your Haier AC unit, you will need to remove the back panel. Turn off the unit and unplug it from the power source. Locate the back panel, which is typically held in place by screws or clips, and remove it carefully. This will expose the internal components of the AC unit, including the air vents.
Using a dry, clean cloth, gently wipe down the air vents to remove any dust, dirt, or debris that has accumulated over time. You can also use a vacuum cleaner with a soft brush attachment to gently remove any stubborn dirt or debris from the air vents. Be careful not to damage any of the internal components while cleaning.
If the air vents are particularly dirty or greasy, you may need to use a mild detergent diluted with water. Dip a clean cloth into the detergent solution and gently wipe down the air vents. Ensure that you wring out the cloth thoroughly before cleaning, as you do not want water dripping into sensitive electrical components. After cleaning with detergent, go over the air vents again with a damp cloth to remove any soap residue. Finally, dry the air vents and internal components thoroughly with a clean, dry cloth before reassembling the back panel.
It is important to note that cleaning the internal components of your AC unit can be delicate work, and improper cleaning can lead to damage. If you are uncomfortable with the process or unsure about what you are doing, it is best to consult a professional HVAC technician or cleaning service to ensure the job is done correctly and safely.

Cleaning the inlet grille
To clean the inlet grille of your Haier AC unit, first ensure that the power is shut off. Next, open the inlet grille by pulling it upward. Remove the filter by gently pushing up on the centre tab until it is released from the stopper, then take it out downward.
Now it's time to clean the filter. You can use a vacuum cleaner to remove dust, or wash the filter with warm water and a mild detergent. Avoid using any chemical cleaners. Allow the filter to air dry completely before reinstalling it. When drying the filter, ensure there is no detergent residue left on the unit.
Once the filter is clean and dry, you can reattach it to the inlet grille. Attach the filter so that the white side is facing forward, ensuring that it is securely attached behind the holding tabs. If the filter is not attached correctly, your AC unit may not achieve maximum efficiency.
Finally, close the inlet grille. Now that the inlet grille and filter are clean, your AC unit will be functioning optimally, and you will notice a difference in the cooling performance.
