Aircon Chemical Overhaul
A chemical overhaul is a deep cleaning service that fully dismantles your aircon to restore performance and fix issues like water leaks or noise.
- Full disassembly & chemical cleaning
- Lubrication of fan bearings for quiet operation
- Cleaning of coils, blower wheel & drainage system
- Inspection of controls & replacement of faulty parts
Perfect for older units or those not serviced regularly. Get your aircon running like new again.
How It Works
Process of Aircon Chemical Overhaul
Dismantling & Chemical Cleaning
The technician fully disassembles the unit, cleaning each component with chemical solutions to remove dust, mold, and grime. This ensures cleaner air and better cooling performance.
Lubricating Fan Bearings
After chemical treatment, fan bearings are lubricated to restore smooth operation. This reduces noise, enhances airflow, and prolongs the lifespan of moving parts.
Reassembly & Thorough Testing
The aircon is carefully reassembled and tested. Electrical connections, circuit performance, and water drainage are checked to ensure safe, leak-free operation.
Refrigerant Level Check
Lastly, the refrigerant level is measured using a gas gauge. If needed, the technician will top up the gas to maintain optimal cooling efficiency and energy savings.

Signs Your Aircon Needs a Chemical Overhaul
A chemical overhaul involves deep cleaning the internal components of your aircon with chemical solutions to remove dirt, mold, and bacteria—restoring both cooling performance and air quality. Here are key signs your unit may need one:
- Poor Cooling Performance
If your aircon takes too long to cool or isn’t producing cold air, ice buildup in the condenser coil could be the cause. An overhaul helps clear the blockage and restore efficient cooling.
- Water Leakage
Water dripping or spraying from the unit often indicates clogged coils or a blocked drainage system. A chemical overhaul can clean out internal parts and stop the leakage.
- Foul Odour
Musty or unpleasant smells usually point to bacteria or mold inside the unit. Chemical cleaning eliminates these contaminants at the source.
- Noisy Operation
Unusual noise may be caused by clogged components, loose bearings, or internal damage. Full disassembly during an overhaul allows these issues to be fixed properly.
Frequently Asked Questions
What’s the difference between a chemical wash and a chemical overhaul?
A chemical overhaul involves fully dismantling the aircon unit to deep clean internal components like coils, blower wheels, and drainage pipes. A chemical wash is less invasive and doesn’t require full disassembly. Overhauls are best for older or problematic units.
How do I know if my aircon needs a chemical overhaul?
If your unit has weak cooling, water leaks, strange smells, or loud noises—and regular servicing hasn’t helped—it’s likely time for an overhaul.
How often should I do a chemical overhaul?
We recommend once every 1–2 years, depending on usage and environment. Units in dusty or humid spaces may need more frequent deep cleaning. Not sure? Contact us for tailored advice.
How long does a chemical overhaul take?
Typically 1.5 to 3 hours per unit, allowing thorough cleaning, lubrication, and testing. Our technicians work efficiently with minimal disruption.
Is it safe to do a chemical overhaul at home?
Yes—if done by professionals. Our team follows strict safety procedures and is fully equipped to carry out overhauls on-site, whether residential or commercial. Book a visit today.
