How often should I clean it?

Air conditioners often lose their cooling efficiency due to a lack of proper cleaning. Whether it is a window-type or split-type unit, it is recommended to inspect and clean the air intake filter every two months.

If the air intake faces a dusty environment, such as a road, the cleaning frequency should be increased to about once a month for optimal performance.

What is the cleaning order?

The technician will start the air conditioner first and check whether all parts are working properly. After confirming that everything is working properly, the machine cover will be removed and the pig cage motor will be thoroughly cleaned with a high-pressure water gun. During the cleaning process, the indoor unit will be covered with a waterproof cloth to prevent sewage from splashing out and keep the surrounding environment clean.

What should I do if there is still an odor after cleaning?

Possible causes include: mold accumulation inside the evaporator or impeller, which requires disassembly and thorough cleaning with an antibacterial cleaner; clogged or moldy drain pipes, which require unclogging and sterilization and flushing with diluted bleach; if the indoor environment is too humid, it is recommended to use a dehumidifier or regularly turn on the "air supply mode" to keep the machine dry.

It’s still not cool after using enhanced refrigerant. Is the air conditioner broken?

If the air conditioner is still not cool even after adding refrigerant, it does not necessarily mean that the air conditioner is broken. It may involve compressor aging, refrigerant leakage, dust accumulation in the exhaust gas or control system failure. It is recommended to find a technician to re-check it thoroughly to find out the real cause and then repair it.

It is still leaking after cleaning, what is the reason?

The drain hose may not be properly reinstalled, which may cause condensation water to leak out. In addition, if the aluminum fins are accidentally bent during cleaning, it will also affect the direction of water flow and prevent water from flowing smoothly into the drain tank. If the drain hole is still blocked, use a thin wire or a cleaning rod to carefully unclog it to ensure smooth drainage.

Does the air conditioner outdoor unit need to be cleaned?

Dust accumulation on the outdoor unit will affect the heat dissipation effect, thereby reducing the efficiency of air conditioning. For general cleaning, you can use a soft brush or vacuum cleaner to gently remove the surface dust, and then use a low-pressure water gun to rinse the heat sink (be careful to avoid spraying the water column onto the circuit part). If a large amount of oil and dirt accumulates on the outdoor unit (such as near a catering environment), it is recommended that a professional technician perform a deep cleaning with high-pressure steam.

Which brand of air conditioner is the most useful?

The most durable air conditioner brands on the market include Daikin, Hitachi, Mitsubishi Electric and Panasonic. These brands have excellent performance in compressor quality, cooling efficiency and durability, and are suitable for long-term use. Among them, Daikin is particularly praised for its stability and durability; Hitachi and Mitsubishi Electric are excellent in energy saving and resistance to high temperature environments. When purchasing, it is recommended to choose a suitable model according to usage needs and budget.

What is the difference between fixed frequency type and variable frequency type?

When a fixed frequency air conditioner is running, the compressor has only two states: on and off. It stops running when the set temperature is reached. The temperature changes significantly and consumes more power. However, a variable frequency air conditioner can automatically adjust the compressor speed according to the indoor temperature to maintain a stable temperature, which has better energy-saving effects and quieter operation. In short, fixed frequency air conditioners are cheaper but consume more power, while variable frequency air conditioners have higher initial costs, but are more energy-saving and comfortable in the long run.

Is it necessary to build a shed to install an air conditioner?

Whether it is necessary to build a scaffold when installing an air conditioner in Hong Kong depends on the installation environment and regulations. Generally speaking, if the installation location requires external wall work, or if there is a need to shield the upper balcony or surrounding environment, a scaffold is required to ensure safety and avoid danger caused by falling objects. In addition, some buildings may require relevant permits to be applied for before installation, especially in apartments or residential buildings, and management regulations must be followed. It is recommended to confirm with the installation company whether a scaffold is required or obtain relevant permits before installation.

How to choose the right air conditioner for yourself?

When choosing an air conditioner, first consider the size of the room and choose the appropriate horsepower (for example, a room of 10-15 square meters would use 1 horsepower). If you want to save power and maintain stability, an inverter type would be a good choice. Next, pay attention to the energy efficiency label; a high-efficiency air conditioner will help you save power. In terms of brands, brands like Daikin and Hitachi are very reliable and have good after-sales service. Finally, choose features based on your budget and needs, such as smart control or air filtration.

Why does the air conditioner often make noise?

First, check whether the sound comes from the air conditioner itself. When the air conditioner is turned on or off, the temperature changes and the internal plastic parts expand and contract, which is a normal phenomenon. Please check whether the wall where the indoor and outdoor units are fixed is stable, and whether the connecting pipes are properly fixed to avoid collision with the outdoor unit or other objects. In addition, when the air conditioner is started or stopped, the refrigerant in the system may also make a louder flow sound during the pressure balance process, which is normal.

What should I do if the air conditioner remote control fails?

First replace the battery with a new one and clean the sensor window of the remote control with an alcohol pad. At the same time, check whether the air conditioner receiver is blocked or covered with dust. You can use a mobile phone camera to point at the buttons of the remote control to check whether the infrared emission is normal. If there is still no response after the inspection, you may need to replace the remote control or repair the motherboard.

Why is the air conditioner sometimes hot and sometimes cold?

There may be many reasons why the air conditioner is intermittently hot and cold. The most common is insufficient refrigerant or leakage, which leads to unstable cooling effect. The indoor temperature is set too high or the sensor is faulty, which may cause the air conditioner to start and stop frequently, resulting in intermittent hot and cold conditions. In addition, dust accumulation in the filter, poor heat dissipation of the outdoor unit, or a large temperature difference between indoor and outdoor will also affect the operation. If the problem persists, it is recommended to ask a professional technician to check the refrigerant quantity, sensor, compressor operation status, etc. to ensure the normal operation of the air conditioner.

Can wall-mounted split air conditioners also leak?

If a wall-mounted split air conditioner leaks water, it is usually because the drain pipe is clogged or damaged, which prevents the condensed water from being discharged normally. If there is too much dust on the filter, it will affect the airflow and may also cause abnormal accumulation and dripping of condensed water. In addition, if the indoor unit is installed at an incorrect angle, the drain pipe is not at the right height, or the condensation plate is aged and cracked, it may cause water leakage. It is recommended to clean the filter regularly, check the drainage system, and ask professionals to repair it when necessary.

The air conditioner has a sour smell, what should I do?

The sour smell of the air conditioner is mostly caused by the accumulation of water, humidity or dust inside the machine, which breeds bacteria and mold. In particular, if the filter, condenser and drain pan are not cleaned for a long time, it is easy to produce odor. In addition, if there is oil smoke or odor in the indoor air, it may also be inhaled and attached to the inside of the air conditioner, further fermenting and producing sour smell. It is recommended to clean the filter, condenser and drainage system regularly, and ask professionals to deep clean it when necessary.

Why does the air conditioner sometimes shut down automatically?

Sometimes the air conditioner shuts down automatically, usually because the room temperature has reached the set temperature and the system enters the standby energy-saving mode. If it is abnormal, it may be that the overheating protection device is activated, the condenser is dirty, the voltage is unstable, the sensor is faulty, or the drainage is poor, causing the safety mechanism to be activated. In addition, some models have a self-detection function, and when an abnormality is detected, it will automatically shut down to protect the body. It is recommended to check the filter, power supply and environmental conditions, and contact a professional for repair if necessary.
