How Much Does Chemical Overhaul Cost in Singapore?

Aircon chemical overhaul 

When it comes to aircon maintenance in Singapore, one of the most frequently asked questions by homeowners and businesses is: “How much does a chemical overhaul cost?” With Singapore’s hot and humid weather, AC run almost daily, leading to dirt buildup, reduced cooling efficiency, and mechanical wear. A regular chemical wash can help, but when the system is heavily clogged or not performing well, a chemical overhaul becomes necessary.

At COOLCARE AIRCON, we believe in transparency, quality service, and helping customers make informed decisions about their aircon maintenance. This article explains the typical cost of chemical overhaul in Singapore, what the service includes, and why it is essential for long-term performance.

What Is a Chemical Overhaul?

A chemical overhaul is a deep cleaning and restoration service that goes far beyond a basic chemical wash. It is recommended when your aircon is experiencing serious issues such as:

• Poor or uneven cooling
• 
  
• Water leaking from the unit
• 
  
• Strong unpleasant odors
• 
  
• Weak airflow
• 
  
• Frozen evaporator coils
• 
  
• Excessive noise or vibration
• 
  

During a chemical overhaul, the entire fan coil unit is dismantled, cleaned with chemical solutions, and inspected for internal damage. This process ensures maximum cleaning efficiency and restores your aircon to optimal working condition.

Chemical Wash vs Chemical Overhaul – What’s the Difference?

Many customers confuse the two services. Here’s a simple comparison:

Chemical Wash

• Basic internal cleaning
• 
  
• For mildly dirty units
• 
  
• No removal of major components
• 
  
• Cheaper but less thorough

Chemical Overhaul

• Full dismantling of the fan coil unit
• 
  
• Deep chemical cleaning
• 
  
• Drain pipe and blower cleaned
• 
  
• Gas pressure checked
• 
  
• Suitable for heavily clogged or leaking units
• 
  

So while a chemical wash is good for regular maintenance, a chemical overhaul is a total reset for your AC system, making it ideal for older or poorly maintained units.

How Much Does a Chemical Overhaul Cost in Singapore?

The cost of a chemical overhaul can vary based on the type of aircon system, unit condition, and service provider. On average, the market rate in Singapore is:

✓ Standard Wall-Mounted Aircon: $120 – $180 per unit

✓ Non-Inverter vs Inverter Units: Slight price difference

✓ System ’s Units (multiple fan coils): Package pricing available

At COOLCARE AIRCON, our chemical overhaul service is a complete restoration package that includes:

1. Full Dismantling of the Fan Coil

The unit is removed from the wall, allowing thorough cleaning of each component.

2. Deep Chemical Cleaning

Coils, blower wheel, filters, and internal surfaces are soaked in safe cleaning solutions that remove:

• Mold
• 
  
• Bacteria
• 
  
• Hardened dust
• 
  
• Grease buildup
• 
  

3. Clearing the Drain Pipe

Choked drain pipes cause water leakage, so they are flushed to ensure smooth flow.

4. Checking Refrigerant Gas Pressure

Low gas levels reduce cooling efficiency, and our technicians top up gas if necessary (additional charge may apply).

5. Inspection of Electrical Components

We check for worn wires, loose contacts, or damaged parts that could impact unit performance.

6. Reassembly and Performance Testing

After cleaning, the entire unit is reinstalled and tested to ensure optimal cooling and airflow.

Why Is Chemical Overhaul Important?

A chemical overhaul offers several benefits:

✓ Restores cooling efficiency

Dirty coils and clogged blowers restrict airflow and slow down cooling.

✓ Eliminates musty odors

Deep cleaning removes bacteria and mold that often cause foul smells.

✓ Reduces water leakage

A clean drain pipe ensures smoother drainage and prevents dripping.

✓ Prolongs the lifespan of your aircon

Removing dirt and corrosion prevents long-term damage to internal components.

✓ Saves electricity

A clean and efficient unit uses less power, lowering your monthly energy bills.

Signs Your Aircon Needs a Chemical Overhaul

If you notice any of the following issues, it’s time to schedule a deep clean:

• Your aircon takes too long to cool
• 
  
• Water dripping or leaking
• 
  
• Persistent bad smell even after cleaning filters
• 
  
• Higher electricity bills
• 
  
• Airflow feels weak or blocked
• 
  
• Unusual noise during operation
• 
  

Ignoring these signs can lead to more costly repairs in the future.
