Lack of Maintenance
Dirt, debris and dust accumulate in an unmaintained aircon and cause it to malfunction.
Wear and Tear
Motors, fans and compressors may wear out and need replacement.
Electrical Problems
Faulty wiring, blown fuses or malfunctioning circuit breakers.
Refrigerant Gas Leakage
Low gas may blow warm air. Leaks can happen in the pipes, the condenser or the unit itself.
Poor Airflow
Weak airflow could mean a faulty motor or clogged air filter.
Noisy Aircon
Rattling, squeaking or grinding could mean a faulty motor, loose parts or damaged fan blade.
Foul Smells
Musty or moldy odor could mean a clogged filter or mold infestation.
Water Leakage
Could be a clogged drainpipe, damaged condenser or refrigerant leak.

Noise from the blower fan may need a fan motor replacement. Noise from the condenser may mean a broken compressor motor. A broken oscillator flap motor can make noise too.

Usually a clogged drainage line causes leakage from the unit. On rare occasions dirty filters can also cause water to drip.

The machine may have run out of refrigerant gas, there may be a leak, or the condenser is not working properly.

Long working hours, clogged air filters, dirty condenser coils or low refrigerant.

The Printed Circuit Board is critical in the indoor unit and outdoor condenser. PCB failure can cause a complete breakdown.
