Singapore’s humidity makes aircons particularly prone to mould and bacteria buildup. A chemical wash removes these contaminants at the source.
Our Aircon Chemical Overhaul Process
We follow a structured 5-step process on every aircon chemical overhaul job.
01
Full Unit Inspection
Our technician inspects your indoor unit for visible dirt, mould, damage, and any signs of water leakage before starting work.
02
Full Dismantle
Unlike a chemical wash, we fully dismantle the indoor unit, including the front panel, filters, water tray, blower wheel, and fan coil. This helps us to access and clean every internal component thoroughly.
03
Chemical Cleaning
A specialised chemical solution is applied to all dismantled components to break down accumulated dust, mould, and bacteria. The drainage pipe is flushed to clear any blockages that may be causing water leakage.
04
Rinse and Reassemble
All components are thoroughly rinsed, dried, and carefully reassembled before the unit is returned to its original condition.
05
Test Run
We run the unit and check cooling performance, airflow, and drainage before we leave. If we spot anything that needs attention, we will let you know immediately.

Posted on Google So Bee SoonTrustindex verifies that the original source of the review is Google. This is the third time I have engaged Jex for air con installation. Jex provides good service from the point of quotation till the finish of installation. Parthi and team have done a good job for the job today. They took care of the debris and cleaned up well. Raja also adviced on adding a curtain to separate the kitchen and living room. He communicated clearly so I could understand his responses to my queries. Well, one bit yet to be completed. The team promised to come by to either paint or change the boards covering the louvred openings of the rooms.

Frequently Asked Questions
1. Will a chemical overhaul fix my aircon if it is leaking water?
Often, yes. Water leakage is frequently caused by a blocked drainage pipe or clogged water tray, both of which are cleared during a chemical overhaul. However, leakage can also result from other issues such as improper installation or a cracked tray. Our technician will identify the cause during the service.
2. Will a chemical overhaul damage my aircon?
The chemical solutions used in a chemical overhaul are corrosive by nature. That is what makes them effective at breaking down mould, bacteria, and stubborn buildup. However, when applied correctly by a trained technician, they will not damage your aircon components.
Our in-house technicians are trained specifically for this and have years of experience handling chemical overhauls safely. The chemicals are applied with care to ensure a thorough clean without causing harm to your unit.
3. What is the difference between a chemical overhaul and regular servicing?
Regular servicing cleans surface components such as the filter, cover, and water tray. A chemical overhaul goes deeper. The unit is fully dismantled and every component is individually cleaned, including the evaporator coil, blower, and drainage pipes that a standard service cannot access. Regular servicing should be done every 3 months; a chemical overhaul once a year.
4 What is the difference between a chemical overhaul and a chemical wash?
A chemical wash partially dismantles the unit and cleans the key internal components in place. A chemical overhaul is a full dismantle where every component is removed, soaked, individually cleaned, and inspected. Read our full guide on the differences between a chemical wash and chemical overhaul here.
5. Why don't you offer a chemical wash instead of a chemical overhaul?
A chemical wash only partially dismantles the unit, which means some internal components are cleaned in place rather than removed and individually cleaned. While it is faster and cheaper, it is less thorough.
We made a deliberate decision to offer chemical overhauls instead. By fully dismantling the unit, our technicians can clean every component properly, spot any early signs of wear or damage, and ensure the job is done right. We believe this delivers better results and better value for our customers in the long run.
6. Do you cover all areas in Singapore?
Yes. We serve residential and commercial properties across all areas of Singapore.
