It may happen, for example, all 5 wall units in a flat are turned on simultaneously, most of the air conditioning systems in Singapore are not designed to work with all wall units turned, please try to turn off one or two wall units when they are not in use.
Another cause may be the doors and windows are left open, please close them whenever the air conditioning is in use. It will cause the air conditioning system to overwork as well as water leakage caused by the condensation conditioning system. Prolonged overworking may cause overheating and permanent damages to the air conditioning system.
If the problem persists, please inform us through email or online submission form immediately, we will schedule inspection/repair work as early as possible, please take note the air conditioning system may suffer further damages if it was kept overworking.
