What Is an Aircon Chemical Wash?
An aircon chemical wash is a deep cleaning process using safe, non-corrosive chemical solutions to remove dirt, mould, and bacteria from the evaporator coil, blower, and drain system.
- Restores cooling performance and airflow efficiency.
- Removes odour-causing bacteria and mould from the coil and fan blower.
- Prevents water leakage and improves energy efficiency.
When Should I Do an Aircon Chemical Wash?
We recommend a chemical wash every 6 to 12 months depending on your aircon usage and environment.
- Every 6 months for heavy or daily use (offices, shops, large families).
- Every 12 months for light home use or aircons in rarely used rooms.
- Immediately if you notice weak cooling, odours, or water leaks.
What’s the Difference Between General Servicing and Chemical Wash?
The difference lies in the depth of cleaning and effectiveness:
-
General servicing cleans external parts — filters, fan coil cover, and drainage — good for regular upkeep.
-
Chemical wash removes deep dirt and mould inside the evaporator coil, blower wheel, and water tray.
- For persistent aircon not cold or leaking water, a chemical overhaul may be recommended.
