Aircon Servicing & Repair in Tampines New Town

A standard clean-and-check takes 30-45 minutes per indoor unit. A chemical wash takes about an hour per unit, and a full chemical overhaul (where the unit is dismantled) takes 1.5-2 hours per unit. Multi-unit visits are faster per unit.

Check the simple things first: thermostat mode and setpoint, dirty filters, and blocked outdoor unit airflow. If those are fine, the usual culprits are low refrigerant from a leak, a failed capacitor or fan motor, or a dirty coil. Low refrigerant always means a leak — a technician should find and fix the leak, not just top up the gas.

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 chemical wash uses a cleaning solution to strip dirt and mould from the evaporator coil, blower wheel, and drain pan without dismantling the whole unit. Book one when a normal service no longer fixes weak airflow, bad smells, or water leaking from the indoor unit — typically every 12-18 months for heavily used units.

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.

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.
