Symptom
Blowing weak + slightly warm
Likely cause
Restricted airflow is one possibility
What we do
Inspect the filter, indoor coil, blower and fan operation. Clean only the affected areas; controls or refrigerant may need separate diagnosis.

Symptom
Cold for a bit, then warm again

Charge, sensor, fan or control fault

Measure operating conditions and look for the cause. If charge is low, diagnose leak or undercharge before any model-matched recharge.

Symptom
Outdoor unit running but indoor blowing room temperature
Likely cause
Outdoor or system fault
What we do
Test the applicable controls and components against the model. Quote a capacitor, board, fan or compressor repair only after the failed item is identified.

Symptom
Aircon won't turn on
Likely cause
Supply, remote, control or internal fault

Check safe external controls first. Do not repeatedly reset a tripping breaker; fixed-wiring faults require an EMA Licensed Electrical Worker.
