Aircon Servicing & Repair in Ang Mo Kio New Town

A standard service covers cleaning or replacing filters, cleaning the evaporator coil and blower, flushing the drainage tray and pipe, checking refrigerant pressure, testing thermostat and controls, and inspecting electrical connections. It does not include repairs, parts, or refrigerant top-ups — those are quoted separately.

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.

Inverter units vary compressor speed instead of switching on and off, so they hold temperature more steadily and cost 20-40% less to run for long daily use. Non-inverter units are cheaper upfront and fine for rooms cooled a few hours a day. For daily whole-day use, the inverter premium usually pays back in 2-3 years.

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.

Most charge a call-out or diagnostic fee that covers travel and the first inspection; many waive or credit it against the repair if you go ahead. Confirm the fee, whether it is credited, and any surcharge for evenings, weekends, or urgent same-day visits before the technician is dispatched.

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.
