For inverter units that are using R410 gas. The optimum pressure is 160. While for units that are using R22 gas. The optimum pressure is 60. There will be a slight difference. It depends on whether your Aircon is system 2, 3 or 4. If your Aircon is not cooling efficiently, you might need to top up your refrigerant.

If LG Aircon servicing is not sufficient to make it cold. You can try Chemical wash, it will ensure that all the dirt, dust and debris are removed. It is by using chemical solution to wash the Aircon evaporator coil without dismantling the unit by itself. However, we do not recommend Aircon chemical wash for all Aircon units. It is more suited to do normal servicing or chemical overhaul for certain Aircon units.

3 Things to Look out for during LG Aircon Servicing


1. Please be careful with the fan motor.

LG Aircon is known to have indoor unit fan motor issues from time to time. Hence, if your Aircon technician were to dismantle the blower wheel for cleaning. Please make sure that they do so carefully. As it may cause damage to the blower wheel if they are not careful during LG Aircon servicing. However, if there is damage, you can immediately notice it after they put it back. So any noisy fan motor sound that does not occur immediately after servicing may be attributed to normal wear and tear instead.


2. Please take note of the mirror cover of certain LG Aircon units.

Please be extremely careful of the LG mirror cover for certain lg Aircon units. We have broken a few pieces during LG Aircon servicing before. Hence we are learning this the hard way. The mirror cover of the LG fancoil unit can be extremely fragile. Therefore the Aircon technician should be familiar with the brand or be extremely vigilant before they commence on the Aircon servicing.


3. LG Non-inverter condenser unit may not be compatible with other brands.

Most non inverter condenser units are mutually compatible. However, non inverter LG condenser unit may not be compatible with other brands. Hence your Aircon technician should ensure that they have the relevant LG aircon spare parts before they undertake the LG Aircon servicing or repair job.

We have made a lot of mistakes when it comes to LG Aircon servicing before. However, we learn things the hard way and we have came a long way. If you need a company that is experienced in LG Aircon servicing, be sure to WhatsApp us.
