The information below is very important. It ensures that the maintenance of the air conditioning system goes smoothly, without causing any damage to the device.

The air-conditioning system has a very complex structure, especially with the central air-conditioning system (including VRV/VRF and Water Chiller systems). Any of the actions listed below may damage the device. The best way to prevent this from happening is to take a closer look at the 5 notes below:

Unskilled people should not interfere with the electrical system of the air conditioner.

1. Air conditioner circuit - Restrict the area for unskilled people

The air-conditioning circuit system is a "forbidden zone" for people who have no experience or knowledge. Any interference or change of connection position in the circuit may result in a fire or equipment damage.

The air conditioning system has a synchronized structure. Any change will adversely affect the device.

2. Arbitrary change of the air conditioner structure

Each air conditioner is manufactured based on the principles and technical standards set by the manufacturer. The change of the air conditioner structure means incompatibility in the structural components. Not only that, say for example, some products are from the same manufacturer, if there is a difference in the year of manufacture, there will be differences in the technology applied. Exchanging outdoor or indoor units from one unit to another will create an immeasurable risk. Therefore, if you do not have adequate equipment, information or an experienced maintenance provider do not attempt it by yourself, the best thing to do is to prevent the exchange of air conditioner structures.

Air conditioning ducts are compared to a trachea.

3. Bend conditional air duct

The pipe is made of copper. After installing the air conditioner, the tube will be covered with insulating foam. The position of the pipe is usually fixed which avoids any type of movement or external forces from impacting it. Over time, both copper pipes and insulation are oxidized. Movement or bending on the tube may cause leakage. Leaking pipes will increase electricity consumption from 20% to 40%. Along with increasing the amount of electricity, the air conditioner must increase its working capacity. Compressors will have no break time which will result in opening and closing continuously. Air-conditioning system will be damaged quickly.

Replacing a compressor means buying a new air conditioner system.

4. Changing compressor -  This can be compared to an "organ transplant" and is very risky

Compressors are like the heart of an air conditioner. A failed compressor means your air conditioner is useless.

A stable air conditioner usually has a life of about 10 years. After this time, the parts will age, reduce elasticity, and may corrode leading to malfunction. Failure to perform regular maintenance is a major cause of compressor damage. In addition, the installation location of the outdoor unit also contributes 50% of the working capacity of the air conditioner. If the outdoor unit is placed close to a wall it may create difficulty through obstructions which might affect the blower, the life expectancy will depreciate and the unit will not survive until the warrant period.

Under normal conditions and good maintenance, if the compressor stops working after 10 years, it is time to replace the air conditioner system. Replace the current compressor with a synchronous structure. No manufacturer has been producing compressors since the last decade because of the advancement of technology.

If the compressor is replaced, it will usually be in a secondhand repaired form, or taken from another company that works almost the same as your air conditioner.

If you are not a professional, don’t take care of the central air conditioning system.

5. Self-maintenance central air conditioning - Enthusiastic but ignorant

With buildings, factories, hospitals, halls, gymnasiums, the air-conditioning system used will be constructed as VRV/VRF or Water Chiller. Maintenance of the central air-conditioning system requires not only eye and ear observation, but also professional measuring equipment. In principle, the central air-conditioning system will have an overall outdoor unit and will distribute cold / warm air into spaces by multiple indoor units. Maintenance, fault detection, repairing central air conditioner must be done only by a professional mechanical - electrical - refrigeration maintenance units.

Above are notes for individual households and units using air conditioners. For owners of buildings and constructions, maintaining the mechanical - electrical team to operate the system is a must. However, accompanied by maintenance personnel may end up being costly- The first important thing for investors. Instead of having to "raise troops", contacting and signing a long-term contract with a M&E unit will help the maintenance process be professional, while helping investors control work and costs. In addition, if you want to increase business benefits, extend the life of the air conditioner system, more than anyone else the investor needs to pay attention to factors affecting capacity and factors that help to save air conditioning system/electrical power.
