Aircon Chemical Overhaul Service
Signs You May Need an Aircon Chemical Overhaul
Severe Cooling Problems
If your aircon continues to provide weak or inconsistent cooling despite previous servicing or cleaning, severe internal buildup may require more extensive dismantling and deep cleaning.
Very Weak Airflow
Significantly reduced airflow may indicate heavy dirt and residue affecting internal components that cannot be cleaned sufficiently through routine servicing alone.
Recurring Water Leakage
Water leakage that continues returning after general servicing may be linked to heavy buildup or blockages within areas requiring more extensive access and cleaning.
Persistent Unpleasant Odours
Strong or recurring musty smells may indicate mould, bacteria, and accumulated residue within internal components that require thorough dismantling and cleaning.
Heavy Internal Buildup
Severe dirt, grime, mould, or residue within the aircon may indicate that less intensive cleaning methods are no longer sufficient for the condition of the unit.
Benefits of Professional Aircon Chemical Overhaul Service
Provides Extensive Internal Cleaning
Dismantling relevant components allows heavy dirt, mould, grime, and accumulated residue to be removed from areas requiring more thorough cleaning.
Restores Better Airflow
Deep cleaning of severely affected internal components helps reduce heavy buildup that may be restricting airflow from the aircon unit.
Improves Cooling Performance
Removing severe dirt and residue from relevant components can help the aircon cool the room more effectively and operate more consistently.
How We Do Our Aircon Chemical Wash

Step 1: Clean the Following Aircon Parts
We will clean the following aircon parts thoroughly:
- Aircon Front Filters
- Aircon Filters
- Evaporator Fin
- Drainage Tray
- Blower Wheel*
*Blower wheel cleaning is included in our normal servicing job scope. However, our tech team will advise our clients if removing the blower is applicable/necessary.
Applicable: Some brands/models do not allow the removal of the blower unless the unit is fully dismantled which falls under the job scope of Aircon Chemical Overhaul.
Necessary: If the blower is less dusty, the tech team will use a brush that is useful to wipe away any dirt or dust accumulated. If the blower is too dusty, the tech team will advise to take down the blower and use water to clean it.

Step 2: Vacuum Drainage Tray and Pipe
Vacuuming the water drainage pipe can help to increase your aircon's lifespan and prevent any aircon leakages.

Step 3: Full Dismantle of the Aircon Unit
Dismantling all the aircon units helps access all internal components.

Step 4: Chemical Cleaning of Internal Parts

Frequently Asked Questions
What Is an Aircon Chemical Overhaul?
An aircon chemical overhaul is an extensive cleaning service that involves dismantling relevant components for thorough cleaning and treatment. It is generally suitable for severely clogged or heavily affected aircon units that require deeper access than routine servicing or less intensive cleaning methods can provide.
When Should I Consider an Aircon Chemical Overhaul?
You may consider an aircon chemical overhaul if your unit shows signs such as:
- Severe cooling problems despite previous servicing
- Very weak or restricted airflow
- Recurring water leakage
- Persistent unpleasant or musty odours
- Heavy dirt, mould, or internal buildup
Our technicians can assess your aircon and recommend whether a chemical overhaul is suitable for its condition.
How Long Does an Aircon Chemical Overhaul Take?
The time required depends on the aircon type, condition of the unit, and extent of dismantling and cleaning required. A chemical overhaul generally takes longer than routine servicing or chemical cleaning because relevant components need to be dismantled, thoroughly cleaned, reassembled, and checked after completion.
Can an Aircon Chemical Overhaul Help a Severely Clogged Unit?
An aircon chemical overhaul can help when severe dirt, grime, mould, or residue has accumulated within areas that require more extensive access for cleaning. By dismantling and thoroughly cleaning relevant components, the service can help improve internal cleanliness, airflow, and cooling performance. The results will depend on the overall condition of the aircon and whether any mechanical faults are also present.
