What Is a Chemical Wash vs Overhaul?
In Singapore, an aircon chemical wash and a chemical overhaul are both forms of deep cleaning, but they differ in scope and intensity.
A chemical wash is a targeted cleaning of accessible aircon components using specially formulated solutions to remove dirt, mould, and bacteria. It typically involves disassembling the cover, filters, and drainage pipe, and is suitable for units that are in working condition but require a hygiene refresh. We recommend scheduling a chemical wash every 6 to 12 months to maintain indoor air quality and cooling efficiency, especially in Singapore’s humid climate, where microbial growth happens quickly. If you’re looking for reliable aircon chemical cleaning services in Singapore, this is the go-to preventive option.
In contrast, a chemical overhaul is a full dismantling of your aircon unit. It includes cleaning the blower wheel, evaporator coil, PC board, and all internal components with powerful aircon chemical cleaning solutions. This process is ideal when your unit is underperforming, leaking, or has not been serviced in over a year. Most units benefit from a chemical overhaul every 1.5 to 2 years, or earlier if there are persistent operational issues.
It is recommended to perform a chemical overhaul to completely remove any remaining chemicals and extend the cooling coil’s lifespan.
Situations That Warrant a Chemical Overhaul
Sometimes, a basic cleaning just isn’t enough. Here are common signs your aircon might need a chemical overhaul:
Persistent foul odour even after a regular wash, often caused by deep-seated mould
Poor cooling or inconsistent airflow, despite recent servicing
Black residue or mildew visible on internal parts of the unit
Recurring issues or breakdowns even after filter cleaning
These symptoms usually indicate deeper contamination or wear within the unit. A full aircon overhaul removes stubborn grime from hard-to-reach parts, restoring cooling efficiency and improving indoor air quality.
What the Chemical Overhaul Process Entails
At Cool Channels, our chemical overhaul process is carried out with care, detail, and proven methods. Here’s how we restore your aircon system:
Step 01
Pre-inspection & Diagnosis
- Review unit history, including last servicing date and reported issues
- Assess cooling output, airflow pressure, and operating sound
- Identify internal concerns like clogged coils, blocked drains, worn fan blowers, or PCB faults
This diagnostic stage ensures we tailor the cleaning scope to your aircon’s needs.
Step 02
Partial or Full Dismantling / Disassembly
- Indoor Unit: Remove the panel, blower wheel, evaporator coil, drainage tray, and fan moto
- Outdoor Unit (if applicable): Detach casing, clean condenser fins, and inspect fan motor
- Disassembly allows us to access and clean every component thoroughly, not just what’s visible
Step 03
Chemical Application & Cleaning
- Use professional-grade alkaline agents like sodium hydroxide to dissolve grease, bacteria, and fungal residue
- Neutralising agents follow to balance pH and ensure no corrosive damage
- Flushing, scrubbing, and pressure rinsing are applied to all components
These aircon chemical cleaning solutions target biological build-up that impacts airflow and health.
Step 04
Reassembly & Testing
- Carefully reassemble internal and external units
- Reconnect electricals, seal components, and perform refrigerant top-up if needed
- Conduct test run to measure airflow strength, cooling time, noise level, and refrigerant cycle
This step verifies that your unit is operating at optimum condition post-clean.
Step 05
Post-Check & Warranty / Aftercare
- Provide hygiene certificate and full service report
- Recommend maintenance frequency based on usage and location
- Offer warranty on workmanship and components serviced
You’ll walk away with peace of mind and clear next steps for maintenance.
