Common Aircon Problems & What They Mean
Not Cooling
Usually low refrigerant gas or dirty coils. Needs gas top-up or chemical wash.
Water Leaking
Clogged drain pipe — most common cause. Technician flushes or replaces the drain line.
Unusual Noise
Rattling = loose parts. Squealing = fan belt. Banging = compressor issue. All need prompt diagnosis.
Bad Smell
Musty smell = mould. Requires a chemical wash or overhaul to eliminate bacteria.
Trips Circuit Breaker
Electrical fault or failing compressor. Requires immediate professional inspection.
Remote Not Working
Could be remote, receiver sensor, or PCB board. Diagnose before replacing parts.

- Repair cost under 40% of new unit price
- Still under manufacturer warranty
Replace When…
- Unit is over 8–10 years old
- Compressor failure (approaches new unit cost)
