Frequently Asked Questions About Aircon

Generally every 3 to 4 months to ensure optimal cooling performance, prevent bacterial buildup, and maintain energy efficiency, especially in Singapore's humid climate.

General servicing is routine cleaning of filters, drainage trays, and checking airflow. A chemical wash is a thorough overhaul involving complete unit dismantling and specialized cleaning solutions to clear stubborn mold and internal clogs, recommended every 6 to 12 months.

Unpleasant odors are typically caused by trapped moisture, mold, mildew, or organic bacteria accumulating on the damp evaporator coil or within the drainage pan.

Loss of cooling is usually driven by clogged air filters obstructing airflow, low refrigerant gas levels due to minor leaks, or compressor performance issues.

Water leaks inside the room are almost always caused by a choked drainage pipe resulting from dust and algae accumulation over time.

Rattling, buzzing, or squeaking noises typically indicate loose casing parts, dirty fan blower wheels, or exterior component vibrations.

A blinking indicator light is your aircon's diagnostic warning system, frequently pointing to an electrical fault, sensor error, or circuit board communication glitch.

Inverter technology dynamically regulates compressor motor speed rather than switching it fully on and off, making units significantly quieter, more durable, and energy-efficient.

Wash your air filters monthly, set room temperatures between 24°C and 26°C, utilize built-in timer functions, and ensure doors and windows remain properly sealed during operation.

Yes, periodic servicing remains important even for underutilized units to prevent dust accumulation, stagnant moisture, and unexpected component degradation.

Proper BTU sizing depends on room square footage, ceiling height, thermal load sources, and direct sunlight exposure (such as west-facing windows).

HDB installations must be carried out by trained professionals, with formal reports submitted through approved contractors where required within standard regulatory windows.
