Aircon Diagnostic Cases

Cooling complaints are the most common reason owners reach out. The unit runs, the fan blows, but the air is not cold — or it starts cold and turns warm after a while. Each case below walks through what the owner reported, what we found on site, and how the fault was resolved.

Water dripping from the indoor unit is one of the most visible aircon problems — and one of the most straightforward to fix when the cause is identified correctly. Most leaks trace back to the drainage system: a blocked drain pipe, a failed condensate pump, or a cracked drain tray.

Electrical faults range from a tripped isolator switch to a failed PCB or compressor drawing excessive current. The symptom — unit won't start, keeps shutting off, or throws an error code — rarely points directly to the failed component without testing.

A sudden change in sound usually signals something specific. A rattle from the outdoor unit, a buzz from the indoor unit, or a vibration that was not there before — each points to a different component.

Airflow and control problems are often the easiest to spot — the air feels weak, the fan is not spinning, or the remote does not respond. But the cause is not always the obvious component.

Sometimes the problem starts after a service visit, not before. A unit that was fine before servicing now leaks, a newly installed system does not cool properly, or a previous contractor's diagnosis did not hold up.
