Aircon Servicing & Repair in Yishun New Town

A unit that trips the breaker at startup usually has a failing compressor, a shorted capacitor, or a wiring fault — all electrical faults that need a technician. Do not keep resetting the breaker; repeated tripping can damage the compressor beyond repair.

The most common cause is a clogged condensate drain line — dirt and algae block the pipe and water backs up into the room. Other causes are a dirty evaporator coil that ices over and then melts, a cracked drain pan, or an incorrectly sloped drain pipe. A drain flush during a standard service usually fixes it.

A musty smell means mould or bacteria on the evaporator coil or in the drain pan — fixed with a chemical wash. A burning smell can be dust on a heater element or a failing motor and is worth an inspection. A vinegar-like or chemical smell can indicate a refrigerant leak; turn the unit off and call a technician.

Pricing depends on the service depth: a basic clean-and-check per unit is the cheapest, a chemical wash costs roughly double, and a full overhaul double again. Multi-unit discounts are standard.

Once a year is the minimum for a system used seasonally; every 3-4 months if you run it daily in a hot climate. Regular servicing keeps coils and filters clean, which protects the compressor — the most expensive part to replace — and keeps energy use down.

With year-round daily use, every 3 months for general servicing is the common recommendation; quarterly contracts (4 visits) for a 3-unit system typically cost $180-$280 per year. A chemical wash every 12-18 months keeps coils clear in Singapore's humidity.

General servicing runs $50-$90 per unit (cheaper per unit in bundles), chemical wash $80-$150 per unit, and chemical overhaul $150-$350 per unit. Gas top-up, if genuinely needed, adds $60-$150 depending on refrigerant and amount.
