Aircon Servicing & Repair in Tampines Estate

You can safely wash or replace filters monthly, keep the outdoor unit clear of leaves and debris, and wipe the indoor casing. Anything involving the refrigerant circuit, electrical components, or coil chemicals should be left to a certified technician — refrigerant handling is legally restricted in most countries.

If you run multiple units daily, yes — contracts usually price each visit 15-30% below one-off rates, include priority booking during heatwaves, and some include minor parts. For a single, lightly used unit, paying per visit is usually cheaper.

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.

A common rule: if the repair costs more than half the price of a new unit, or the system is over 10-12 years old and needs a compressor or coil replacement, replace it. Newer inverter units are typically 30-50% more efficient, so heavy users recoup part of the cost through lower bills.

Get 2-3 quotes and compare what each service actually includes — some cheap quotes cover only a filter rinse. Check for the refrigerant-handling certification required in your country, ask how long they have serviced your brand and type of system, and read recent reviews that mention follow-up visits, not just the first appointment.

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.
