What is an Aircon Chemical Overhaul?
An aircon chemical overhaul is a deep cleaning service designed to thoroughly clean and restore your air conditioning unit from the inside out. Unlike standard servicing, this process involves dismantling key components and cleaning them with specialized chemical solutions to remove stubborn dirt, mold, and mineral buildup that affect performance.
This service is ideal for aircons that are leaking, blowing weak air, producing bad odours, or showing signs of wear and tear.

338's Aircon Chemical Overhaul Includes
A chemical overhaul uses the same chemical acid as a chemical wash does.
However, the difference is that the whole fan coil is dismantled and brought down for thorough cleaning in an overhaul service. All of the internal parts are fully removed and cleaned chemically.
The chemical overhaul will take around 1 hour per unit, with the scope covering:
-
Dismantling the aircon unit for washing.
-
Spraying the fan coil with chemical compounds.
-
Chemically cleaning the fan blower component.*
-
Washing & cleaning the water tray component.
-
Chemical treatment for the air filters.
-
Washing all the parts thoroughly with water.
-
Wiping & cleaning all the aircon parts & components.
-
Reassembling the whole aircon unit.
* Depends on the model & condition of FCU.

Why You Need an Aircon Chemical Overhaul
Regular Services are No Longer Sufficient
Regular aircon cleaning and chemical washing may not be able to reach every part of the air conditioning unit, leading to dirt and grime buildup in certain areas.
An aircon chemical overhaul reaches those hidden areas and also cleans and repairs aircon components not usually serviced, such as back trays.
Improves Efficiency of Air Conditioners
During an aircon chemical overhaul, the aircon technicians look over the aircon completely, ensuring that every part is cleaned and working as intended.
This ensures that your air conditioning unit operates quietly, produces cold air and maintains temperature efficiently.
Reduces Electricity Bills
In general, better-maintained equipment will operate more effectively. A poorly maintained air conditioning system uses more energy in order to function.
When your air conditioner is thoroughly cleaned and properly serviced, it can function at optimum efficiency without consuming excessive power.
Better Air Quality
Poorly maintained air conditioning units can raise your risk of “sick building syndrome", irritate your respiratory system and ramp up allergies.
An aircon chemical overhaul consists of an intense and detailed cleaning that rejuvenates the entire unit and internal components.
Extends Air Conditioner Lifespan
During an aircon chemical overhaul, our professional technicians will disassemble it to check for any problems and repair any worn parts.
This is why an aircon chemical overhaul is often advised for aircon units that have not been regularly maintained.

When You Should Get a Chemical Overhaul
Your aircon is more than 2 years old and never had a deep clean
You’re experiencing frequent aircon breakdowns
You notice water leaks, loud noises, or a musty smell
How Often Should You Do a Chemical Overhaul?
A chemical overhaul should typically be done every 1 to 2 years, depending on how often and heavily the air conditioner is used. For households or offices that run their units daily, an annual overhaul is ideal to maintain cooling performance and energy efficiency. However, signs like water leakage, weak airflow, or persistent noise after regular servicing may indicate it’s time for a more thorough chemical cleaning.
You should also consider a chemical overhaul after major renovations or if your aircon has been exposed to heavy dust, as particles can clog internal components.
Older units, especially those over five years old, may benefit from more frequent overhauls to prevent wear and tear. Keeping a regular overhaul schedule helps prolong the system’s lifespan, reduce power bills, and ensure better indoor air quality.
A chemical wash involves cleaning the coils, air filters, and water tray using a chemical solution to remove dirt, mold, and harmful bacteria. You can mostly see improvements in airflow and energy efficiency.
In addition to the chemical wash, an aircon chemical overhaul involves a deeper cleaning of the drainage pipes, heat exchange coils, and blower wheels. Any damaged parts are repaired or replaced during the process. It is recommended once a year.

FAQs on Aircon Chemical Overhauls
Frequently Asked Questions
What is a chemical overhaul for aircon units?
A chemical overhaul involves a thorough cleaning process for your air conditioning unit. It removes dirt, grease, and accumulated dust particles that can affect airflow and temperature. This service is crucial for units that haven't been serviced in over a year.
Why is a chemical overhaul necessary?
Regular cleaning removes some debris, but it can't eliminate harmful gunk that accumulates in the condenser, filter, and evaporator coils. This gunk can damage internal components and reduce efficiency.
How often should I do a chemical overhaul?
It’s recommended every 1 to 2 years, depending on usage. Heavily used units or older systems may need an overhaul annually, while lightly used systems may need one every 18–24 months.
What are the benefits of chemical washing for aircon units?
Improved Air Quality: A clean unit ensures better air circulation, helping to prevent respiratory issues caused by poor indoor air quality.
Reduced Breakdown Frequency: Regular maintenance and chemical washing prevent potential breakdowns, reducing repair costs and improving system reliability.
Enhanced Performance: Cleaning removes blockages, allowing your unit to cool rooms faster and operate more efficiently, ultimately saving on electricity bills.
Is a chemical overhaul safe for all aircon types?
Yes, it’s safe for most residential and commercial split-type and cassette aircon units. Professional technicians will assess the condition and ensure proper handling of your system.
How long does a chemical overhaul take?
A standard chemical overhaul usually takes 1 hour per unit, depending on the aircon type and condition.
Should I choose a chemical wash or a chemical overhaul?
Choose a chemical wash if your aircon is regularly maintained and only has minor dirt buildup or reduced airflow. Opt for a chemical overhaul if your unit has major cooling issues, heavy grime, strange noises, or hasn’t been serviced in over a year—it involves deep cleaning with full disassembly for maximum performance restoration.
