Aircon upkeep in Singapore: filters, drainage, and saving energy
Simple habits that keep bedrooms cooler, bills steadier, and service calls predictable—not only when the unit stops cooling.
Wash or replace indoor filters on the schedule your installer recommends—often every two to four weeks in heavy use. Dry completely before reinstalling to reduce mould odours and improve airflow.
Check that condensate drains are not blocked by dust or insect nests; water stains on walls near the indoor unit are a warning sign. Outdoor compressors need breathing room—move storage boxes and plants that block airflow.
Set a comfortable baseline temperature instead of cycling to extreme cold. Annual professional servicing catches refrigerant issues early and is cheaper than emergency repairs during peak heat waves.
If a room never reaches set point, note whether it happens after rain or only in afternoon sun—those clues help technicians diagnose faster on WhatsApp before they arrive.
