Complete Aircon Chemical Overhaul Singapore

9K – 15K BTU

An aircon chemical overhaul in Singapore is the most comprehensive method of restoring an air conditioning system to peak performance. It involves complete disassembly of the unit so that every component can be intensively cleaned with specialised chemicals. This process removes stubborn dirt from the evaporator and condenser coils, pipes, blower wheel, and drain pan, while also treating the drainage system to prevent leaks. The technician inspects and lubricates fan bearings for quiet operation, checks thermostats and controls, and replaces any faulty parts to eliminate noise or inefficiency. A chemical overhaul is ideal for older units or systems that have not received regular maintenance, as it solves persistent issues that standard servicing or chemical washes cannot fix. GoodCool provides this full overhaul service from $163.50, backed by more than ten years of experience and a 90-day warranty. WhatsApp Us Now!

Our 4-Step Aircon Chemical Overhaul Process

Dismantling whole aircon unit for Chemical Overhaul

Step 1: Complete Dismantling of the Aircon Unit

The key distinction of an aircon chemical overhaul is the full disassembly of the unit, allowing the technician to meticulously remove and treat every component with a specialized chemical solution. This process eliminates accumulated dust and mold from hidden, hard-to-reach areas that regular chemical washes cannot access. By exposing these areas, the technician ensures a thorough cleaning, leading to improved air quality and more efficient cooling. To ensure transparency, we photograph the unit’s condition before cleaning, allowing for complete immersion treatment of all surfaces, including those previously inaccessible.

Step 2: Fan Bearing Lubrication

After chemical treatment, moving parts need re-lubrication. We inspect bearings for wear, apply high-grade oil, replace worn bearings (no extra charge). Proper lubrication eliminates squeaking, ensures quiet operation, prevents motor failure.

Step 3: Reinstallation and System Testing

Once the overhaul is complete, the technician reassembles all parts. This precise reinstallation is why professional expertise is essential. The technician then conducts a thorough test to check electrical connections, ensuring safety, correct circuit functioning, and verifying there are no water leaks and that the aircon operates effectively.

Step 4: Refrigerant Level Inspection

The final step involves checking the air conditioner’s refrigerant level, a critical factor for its energy efficiency and performance. Technicians use a gas gauge for this assessment and, if necessary, top up the refrigerant gas. This ensures the aircon provides the coolest and freshest indoor environment.

Signs You Need an Aircon Chemical Overhaul (Not Just a Wash)

If your aircon is weak or warm airflow, water leaking, bad or musty smell. A chemical overhaul can effectively resolve these issues.

1. Persistent Poor Cooling Despite Regular Servicing

Air conditioners are designed for efficient cooling. If your unit takes too long to cool a room or fails to produce cold air, it could be due to ice accumulation in the condenser. In such cases, a detailed maintenance process is necessary to defrost the coils and check for any damages.

2. Continuous Water Leakage After Chemical Wash

Clogged coils can lead to water being trapped and overflowing in the unit, resulting in leaks or water spray. Since it’s challenging to determine if the coils are clogged, a complete aircon maintenance overhaul is often recommended.

3. Stubborn Foul Odors That Keep Returning

An unusual smell from your air conditioner is not normal and could indicate bacterial growth inside the unit. A thorough maintenance process can effectively eliminate these bacteria.

4. Loud Operational Noise & Vibrations

A loud air conditioner often suggests internal damage, such as clogged coils, water buildup, or loose bearings. A comprehensive maintenance overhaul, which involves disassembling the unit, can identify and resolve these issues. After the maintenance, a test run will determine if the noise issue has been resolved.

For those looking for a quicker and less invasive option, our chemical wash service offers a faster solution for purifying your system without the need to dismantle the entire unit.

Frequently Asked Questions

What is the difference between an aircon chemical wash and an aircon chemical overhaul?

A chemical wash is a mid-level cleaning service meant to remove dirt, dust, and grime from key parts of the air conditioner without dismantling the entire unit.

A chemical overhaul involves fully dismantling the unit to deep clean each internal component, including coils, blower wheels and water tray. In contrast, a chemical wash is less invasive and does not require full disassembly.

How do I know if I need an aircon chemical overhaul?

Signs include poor cooling performance, persistent water leakage, strange smells, or unusual noise from your aircon unit. If you’ve tried regular servicing and the issues persist, it’s likely time for a chemical overhaul.

How often should I schedule an aircon chemical overhaul?

It is recommended every 1 to 2 years for most units, depending on usage and environmental conditions. However, units in high-dust or high-humidity areas may require more frequent deep cleaning.

How long does an aircon chemical overhaul take?

The process usually takes about 45-60mins per unit. This ensures every component is properly cleaned, re-lubricated, and tested. Our experienced technicians aim to complete the job efficiently with minimal disruption.

Is it safe to perform an aircon chemical overhaul at home?

Yes, when carried out by trained professionals. Our technicians are fully equipped to perform such services safely on-site, whether at home or in a commercial setting. We follow strict safety protocols to protect your space and ensure top-quality results.
