I just installed the Mitsubishi Electric's 5 tick System 3 aircon (MXY-3G28VA) with MSXY-FJ13VE (12k BTU) for master bedroom and 2 x MSXY-FJ10VE (9k BTU) for common bedrooms.

The master bedroom aircon takes a very, very long time to cool the room (several hours) if all 3 bedrooms use aircon. If only 2 rooms use the aircon, it's fine.

I'll call Gain City to see if anything can be done, e.g. give priority to master bedroom. My flat is the old flat with unupgraded power loading.
