Aircon Servicing & Chemical Wash in Singapore

What Is Aircon Servicing & Chemical Wash?

An Aircon Servicing & Chemical Wash by Express Plumbing & Elect Services is the ultimate refresh for your cooling unit, stripping away years of stubborn dirt, mold, bacteria, and jelly-like grime hidden deep inside your system. In Singapore's non-stop tropical heat, regular maintenance is non-negotiable if you want your air conditioner to run efficiently. This deep-cleaning service involves dismantling the fan coil unit, flushing the internal components with non-corrosive chemical solutions, and thoroughly clearing out drainage lines. Whether you are living in an HDB in Tampines, a condo in Bedok, or a landed home in Sengkang, keeping your air conditioning system properly serviced ensures fresh indoor air, lowers your monthly power bills, and extends the lifespan of your unit.

When Do You Need Urgent Aircon Servicing?

You need a chemical wash immediately if your unit starts blowing warm air, spewing foul, musty odors, or constantly leaking water down your walls. Physical symptoms like ice buildup on the cooling coils, loud rattling noises from the blower fan, or a sudden spike in your electricity bill mean your system is choked and working twice as hard to cool the room. Left unserviced, a completely blocked FCU can overload the compressor or cause an electrical trip in your circuit breaker. For busy households in places like Hougang and Ang Mo Kio, waiting until the aircon completely dies only leads to hot, uncomfortable nights and more expensive emergency repairs down the road.

How often should I chemically wash my aircon in Singapore?

For residential units used daily, we recommend a general service every 3-4 months and a full chemical wash once a year. Commercial units or aircons running 12+ hours a day may need chemical washing every 6 months.

Why is my aircon leaking water after servicing?

If your aircon still leaks after a general service, the drain pan or internal coil is likely still choked with grime that a basic service can't reach. A chemical wash dismantles and deep-cleans the coil and drain pan to fully resolve persistent leakage.

What's the difference between general aircon servicing and a chemical wash?

General servicing cleans filters and flushes the drain line. A chemical wash dismantles the fan coil unit, chemically treats the evaporator coil and blower wheel, and flushes all internal components — restoring cooling performance and eliminating mould odours.

Will a chemical wash make my aircon colder?

Yes. A chemical wash removes the layer of grime and mould on the evaporator coil that blocks heat exchange. After cleaning, most units show a noticeable improvement in cooling output and a drop in electricity consumption.

How long does an aircon chemical wash take?

A chemical wash for a single fan coil unit takes about 45-60 minutes. We dismantle the unit, chemically treat the coil and blower, flush the drain pan, reassemble, and run a performance test before completing the job.
