I'm aware of the situation and we are now checking what causes the air compressor units to not working properly. It's probably because of the heat ventilation in which I need to check with the 3rd party who can build the tube to control the hot air ventilation. Sorry for what happen. We sent one technician to check this morning and he said the air compressor couldn't work normally. But now if you said none of the air con is working properly that's probably need to fix the ventilation system. I will try my best to help coordinating this for you ka.
