How Our Aircon Chemical Overhaul Works
We fully dismantle and clean the entire aircon unit, removing accumulated dirt from every part.
We apply a chemical solution to deep clean the evaporator coil, condenser coil, and blower wheel for optimal cooling.
All chemically treated parts are jet-washed with clean water to remove any remaining debris and chemical residue. Components are then thoroughly dried before reassembly.
We use a wet vacuum to remove blockages from the drainage tray, preventing sludge and ensuring proper water flow.
We inspect and tighten all electrical contacts to ensure safe, reliable operation and prevent electrical issues.

Aircon Chemical Overhaul FAQs
A chemical overhaul is a deep-cleaning process where the aircon unit is fully dismantled, and key components are chemically washed to remove built-up dirt, grease, mold, and bacteria that regular servicing cannot eliminate.
It is recommended when:
- Cooling performance remains poor after normal servicing
- There is persistent bad odor from the unit
- Water leakage keeps recurring
- The unit has not been serviced for a long period (typically 12 months or more)
- Heavy dirt or mold buildup is observed
Normal servicing: Surface cleaning of filters, fan blower, and basic checks
Chemical wash: Partial cleaning using chemicals without full dismantling
Chemical overhaul: Full dismantling + chemical cleaning of internal components, offering the most thorough cleaning and performance recovery
Yes. When performed by trained technicians using approved chemicals and proper dismantling procedures, it is safe and helps extend the lifespan of the unit.
Generally:
- Once every 12–24 months, depending on usage and environment
- More frequent may be required for heavy usage or dusty environments
In many cases, yes — especially if leakage is caused by clogged drainage or heavy dirt buildup. However, leaks caused by installation or piping issues may require separate rectification.
No. Gas top-up is not included and will only be recommended if a gas leak or low refrigerant level is diagnosed.
It is suitable for:
- Wall-mounted split units
- Cassette units (subject to site assessment)
For ceiling-concealed or commercial units, a site check may be required.
Technicians will use protective covers and proper drainage tools to minimize mess. Some water usage is expected, but the area will be cleaned after service.
