Aircond as well as any other electrical equipment will have problems after several years or after the warranty period expires. However, some have problems before the warranty period ends especially aircond and water heater for examples. In this case you are advised to refer back to the service center or electrical shop where you purchased the equipment.
But problems with air conditioning can lead to 2 types of damage, major damage and minor damage.
Major damage occurs when the air cond compressor is not working. In this case the compressor cannot be repaired and needs to be replaced. The cost of replacing this compressor is high and involves most of the major works such as silfosing, filling gas, vacuum and testing leaks. Therefore, it is recommended that the whole unit be changed.
Minor damage can be repaired, serviced or replaced only the components that do not involve too high costs. In such case you may refer to an accredited technician to detect the damage and make repairs.
Knowing frequent issue with air conditioner
Here, we will list some of the frequent problems in air conditioning units based on frequent complaints and inquiries. At least you can have some knowledge before referring to a technician. There are some problems that you can fix yourself and this will certainly save you costs!
1. The unit is less cold
This problem occurs when you feel the room is less cool, unlike you first bought the aircond unit. This problem is common and it is not a major damage that I mean above. Users will usually assume the gas is running out. Is this theory true?
This theory is NOT TRUE at all. The less cooled unit is not due to gas, but the run out gas situation will lead to a non-cooler unit like the second problem below. What happens in colder units is that the unit may be lacking in gas and it should be added according to the pressure set by the certified technician. This can be done when doing the service and standard gas pressure is 70 PSIG.
The less cooled unit problem can also be caused by dirty air filters, evaporators and condenser condensers as well as impurities on the front panel of the inner unit. In this case, what needs to be done is to make a regular service every 6 months. All the specified parts should be cleaned up using chemicals (if necessary) at a cost of around RM100 – RM150.
2. The unit is not cold at all
It may be caused by a leak in the system that causes the gas to run out. Therefore, the source and place of leakage should be identified and repaired first before you continue to refill the gas. Sometimes this problem is also due to the non – rotating inner blower. Therefore, you are advised to set the remote-control blower speed to maximum and select mood cool. If there is still an issue in the indoor electronic board, it should be checked.
3. Water drips on the indoor unit
This problem may have arisen from dirty evaporation, blocked drainage, disproportionate units and also excessive heat difference between indoor and outdoor rooms. The restoration proposal is that the unit needs to be serviced as well as possible. To reduce the temperature difference, make sure that the window or door is closed
4. Water drips on the outdoor unit
This is not a major problem as long as you feel the room is still cool. The dripping water is from the condensation process that prevails in the condenser and it is normal.
5. Direct unit is not operating
If the unit does not operate and the unit lights are not ON after the ‘remote’ being press, it is most likely no power supply in the room or electricity is tripped. You need to turn on back the main fuse.
6. Outside unit is noisy
It certainly annoys you. More and more at night because it may cause your sleep disturbed. Hence, to prevent further damage, you should check immediately. The main possibility is that the blower is not properly installed.
In a nutshell, every air-conditioner should be serviced at least once every four months for a low level of use. But for everyday air-conditioning, it’s best to serve in every month. More importantly, if the air conditioner shows the following signs, you should get a professional service such as the sale dealer for Mitsubishi air conditioner itself for immediate inspection.
