Lion City Aircon

Maintenance and Servicing

• • How often should I service my aircon? Generally every 3-4 months to ensure optimal performance and prevent bacterial growth, especially in humid climates.

• • What is the difference between general servicing and chemical wash? General servicing is routine cleaning (filters, air flow check), while chemical wash is a deeper cleaning for the unit’s internal components, usually done every 8-12 months.

• • Why does my aircon smell? Bad odors are often due to mold, mildew, or bacteria building up on the damp evaporator coil or drain pan.

Common Issues and Troubleshooting

• • Why is my aircon not cold? This could be due to a clogged air filter, low refrigerant/gas levels, or a faulty compressor.

• • Why is my aircon leaking water? Water leaks are usually caused by a clogged drainage pipe.

• • Why is my aircon noisy? Rattling or buzzing noises can indicate loose parts, dirty fan coils, or a vibrating compressor.

• • What does it mean when the light blinks? A blinking light often indicates a faulty circuit board or electrical issue.

Usage and Efficiency

• • What is an inverter aircon? Inverter technology allows the compressor to vary its speed, making the unit quieter, more energy-efficient, and better at maintaining a constant temperature.

• • How can I save on aircon energy bills? Clean filters monthly, set the temperature between 24 ℃ to 26 ℃, use timer functions, and ensure the room is sealed properly.

• • Should I service the aircon if I don’t use it much? Yes, to prevent dust buildup and mold, which can affect air quality.

Installation and Selection

• • How do I choose the right aircon size? It depends on room size, sunlight exposure (west-facing), and usage. Undersized units will work too hard, increasing costs.

• • What are the HDB guidelines? In Singapore, installation should be performed by BCA-trained technicians, and a report must be submitted to HDB within 14 days.
