What is an Aircon Chemical Overhaul and Why Is It Needed?

In Singapore's relentless heat and humidity, your aircon works overtime. Over time, simple aircon servicing might not be enough to combat the stubborn grime and mould that builds up deep within your unit. When you notice weaker airflow, unpleasant odours, or leaking water, it’s a sign that your aircon needs more than just a surface clean—it needs an aircon chemical overhaul.

This guide will explain what an aircon chemical overhaul is, why it's a crucial part of aircon maintenance in our climate, and how it differs from other cleaning services. Understanding this intensive process is key to restoring your unit's performance and protecting your investment.

What is an Aircon Chemical Overhaul?

An aircon chemical overhaul is the most comprehensive and restorative form of aircon cleaning available. Unlike a standard service, it involves the complete dismantling of the indoor fan coil unit (FCU). Aircon technicians take apart every component—the evaporator coils, fan blowers, drain pan, and pipes, to give them a thorough and deep clean.

Each part is then washed with specialised, non-corrosive chemical solutions designed to break down and flush out deep-seated contaminants like mould, bacteria, grease, and even rust. This process ensures a full restoration of your aircon unit from the inside out, reaching areas that are impossible to clean otherwise.

Why is a Chemical Overhaul Important for Your Singapore Aircon?

Regularly putting your unit through an aircon chemical overhaul is one of the best things you can do for its health and performance. The benefits are significant:

  • Restores Peak Cooling Efficiency: By removing all the insulating layers of grime and mould from the coils and blower, the overhaul allows your aircon to absorb and expel heat far more effectively. This restored efficiency means colder air, stronger airflow, and a noticeable drop in your electricity bills.
  • Eliminates Harmful Contaminants: The moist, dark environment inside your aircon is a perfect breeding ground for mould and bacteria. A chemical overhaul eradicates these allergens, eliminating foul odours and ensuring the air you and your family breathe is clean, fresh, and healthy.
  • Extends Your Aircon's Lifespan: Deep-seated grime and corrosion put immense strain on your aircon’s components, leading to premature wear and tear. By thoroughly cleaning and servicing these parts, an overhaul prevents costly breakdowns and significantly extends the operational lifespan of your unit. 

Chemical Overhaul vs. Other Aircon Services: What's the Difference? 

It’s important to distinguish an overhaul from other common services.

  • General Servicing: This is basic aircon maintenance that includes cleaning the filters, checking refrigerant levels, and a superficial wipe-down of the unit. It’s great for routine upkeep but doesn't address internal build-up.
  • Chemical Wash: A chemical wash is more intensive than general servicing, as it uses chemical agents to clean the indoor unit’s coils. However, it typically does not involve the complete dismantling of the unit, meaning it cannot clean the fan blower, bearings, and other internal parts as thoroughly as an overhaul.
  • Chemical Overhaul: This is the ultimate solution. The complete disassembly guarantees that every single component is individually and meticulously cleaned and serviced, offering a level of deep cleaning and restoration that no other service can match.

When Does Your Aircon Need a Chemical Overhaul?

Wondering how often you should do a chemical overhaul for your aircon? Look out for these clear warning signs that your unit is due for this intensive servicing:

  • Poor Cooling Performance: The air isn’t as cold or consistent as it used to be, signalling reduced efficiency.
  • Foul or Musty Odours: Persistent unpleasant smells are a strong indicator of mould and bacterial build-up inside the unit.
  • Persistent Water Leaks: Clogged drain pipes or internal blockages that routine servicing cannot clear often cause leaks.
  • Unusually High Electricity Bills: If your aircon works harder to achieve the same cooling effect, it’s likely struggling internally.
  • Loud or Strange Noises: Grinding, rattling, or other unusual sounds suggest clogged or strained components.

For most households in Singapore, we recommend a chemical overhaul every 12 to 18 months to maintain optimal performance and air quality.
