Common problems
Air Conditioning Not Blowing Cold
The unit runs and the fan blows, but the air coming out is room temperature or barely cool.
Water Dripping From The Indoor Unit
Water is running down the wall below the indoor head, or dripping off its bottom edge onto the floor.
Ice On The Pipework Or Indoor Unit
There is frost or solid ice on the copper pipes, on the coil behind the indoor grille, or on the outdoor unit's valves.
Error Code Or Flashing Light On The Unit
The indoor head is flashing its timer or operation lamp in a pattern, or the wall controller is showing a code like E4 or U0.
Outdoor Unit Not Running
The indoor head blows air and the lights are on, but the box outside is silent and its fan never turns.
Rattling, Gurgling Or Vibrating Noise
The system has become noisy: a rattle from the indoor head, a drone or vibration from the unit outside, or gurgling in the pipework.
