Full dismantling and deep chemical cleaning for heavily contaminated fan coils, persistent weak cooling, recurring leaks and stubborn odours.
When routine servicing or a lighter chemical wash is no longer enough, an aircon chemical overhaul in Singapore provides a more extensive cleaning process.
Major indoor-unit components are dismantled so areas such as the evaporator coil, blower, drainage system, filters and housing can be cleaned more thoroughly before the unit is reassembled and tested.
Chemical overhaul prices start from $152.60 for one fan coil, inclusive of 9% GST and transportation, with a 90-day workmanship warranty.
A chemical overhaul is generally considered when deeper internal contamination or recurring problems remain after normal aircon servicing .
Deep dirt around the coil or blower can continue restricting airflow even after routine maintenance.
Severe internal buildup can reduce heat transfer and cooling performance.
Heavy dirt or imbalance around internal fan components may contribute to abnormal noise.
Persistent buildup around the drainage tray and internal drainage components may require deeper cleaning.
Mould and residue deeper inside the fan coil can cause odour to return after surface cleaning.
Severe evaporator-coil buildup may affect cooling and dehumidification performance.
Restricted airflow may contribute to icing, although refrigerant or mechanical faults can also require separate diagnosis.
The comparison below shows internal components before and after deep cleaning during an overhaul.
Deep dismantling and cleaning for heavily contaminated fan coils, with GST and transportation included.
The overhaul process provides deeper access to the indoor unit than routine servicing or a chemical wash.
If refrigerant work is required, it should be assessed separately under our aircon gas top-up service .
See how LK Brothers carries out a chemical overhaul by dismantling the fan coil, cleaning internal components and reassembling the unit for testing.

Number of Aircon Units (9,000–12,000 BTU) |
1-Time Chemical Overhaul |
|---|---|
| 1 Fan Coil | $152.60 |
| 2 Fan Coils | $283.40 |
| 3 Fan Coils & Above | $130.80 per unit |
The unit is inspected, dismantled, chemically cleaned, reassembled and tested before completion.
Inspect the fan coil and dismantle the relevant indoor-unit components for deeper access.
Clean the evaporator coil, blower, drainage tray, filters and related components.
Reinstall the cleaned components and restore the fan coil assembly.
Test the aircon's operation, airflow and cooling condition after reassembly.
Both services provide deeper cleaning than routine servicing, but they are intended for different levels of contamination.
A chemical wash is suitable when deeper cleaning is needed but extensive dismantling is not required.
A chemical overhaul involves deeper dismantling and access to internal components, making it more suitable for severe dirt, recurring problems or fan coils that remain heavily contaminated.
Compare Chemical Wash
Book a chemical overhaul for fan coils with severe internal buildup, persistent odour, recurring leakage or weak airflow after routine servicing.
An aircon chemical overhaul is a deep cleaning process where major indoor-unit components are dismantled for more thorough cleaning.
A chemical overhaul may be suitable when a fan coil has significant internal buildup or persistent symptoms after routine servicing.
The service includes dismantling, deep chemical cleaning and reassembly of the relevant fan-coil components.
Refrigerant-related work, if required, can be assessed separately under our gas top-up service .
The key difference is the depth of dismantling and cleaning.
For a less intensive deep clean, see our aircon chemical wash .
LK Brothers' published aircon chemical overhaul prices are:
LK Brothers' existing customer-facing service guidance states approximately 1.5 to 2 hours per fan coil unit, depending on the model, condition and accessibility.
Multiple fan coils will naturally require additional time.
A chemical overhaul can help when weak cooling is caused by severe dirt or internal airflow restriction.
However, poor cooling can also be caused by refrigerant, electrical, fan or compressor faults. If cleaning is not the cause, book our aircon repair and troubleshooting service for diagnosis.
Yes. LK Brothers provides a 90-day workmanship warranty on completed chemical overhaul jobs.
Choose routine servicing, chemical cleaning, repair or refrigerant work according to your aircon's condition.
