After 7 years of using Toshiba inverter, suddenly the aircon is no longer cold. I called up gain city to top up R410, damage was SGD80. After a few days, it is no longer cold. I called up the technician (from gain city). I was told that maybe there is some leak and not worth it to do pressure test and he suggested me to change my aircon.
Anyone can suggest what should I do ? Changing the aircon will cost me 3k (for system 3)
