Why Regular Aircon Servicing Saves You Money

Skipping servicing feels like saving money. It is one of the more expensive false economies in home maintenance, and the arithmetic is not close.

A dirty coil costs you every month

Dust on the evaporator coil insulates it. The unit has to run longer to move the same heat, which shows up directly on your bill — typically a noticeable rise well before cooling visibly degrades.

Blocked drainage becomes ceiling damage

A clogged drain pan overflows into the wall cavity. Clearing a drain during a routine service costs a fraction of repainting a water-damaged ceiling.

Compressors fail from neglect, not age

The compressor is the single most expensive component. It fails when it runs hot and long — which is exactly what a fouled coil and low refrigerant cause. Regular servicing is the cheapest compressor insurance available.

What a general service should include

• Filter and front panel cleaning
• Evaporator coil vacuum and wipe-down
• Drain pan and pipe clearing
• Gas pressure and temperature differential check
• A diagnostic report telling you what changed since last visit

How often

Quarterly for typical Singapore households. Monthly-to-bimonthly if units run overnight, every night, or if you have pets.
