Chemical Wash


Jason Tan
Booked a chemical wash through StringsSG because my aircon was smelling musty and not cooling well. The technician dismantled the whole unit and cleaned every part thoroughly. Now the air feels fresh and cooling is back to normal. Worth every cent!
Amanda Koh
I always thought normal servicing was enough until my aircon started leaking water again and again. This time I booked a chemical overhaul via StringsSG. The process was very detailed — they even cleaned the drainage pipe and fan coil. No more leaks since then!
Hafiz Rahman
The StringsSG app makes it so convenient to get a chemical wash without endless phone calls. The technician explained the whole process and showed me the amount of dirt and mould removed. My aircon feels brand new now.
Elaine Wong
Had a chemical overhaul done for my living room unit as it was over 5 years old. Booking was instant, and the price was clearly shown upfront. The team did a fantastic job, and my electricity bill has gone down because the cooling is much faster.
Suresh Kumar
Tried StringsSG for a chemical wash after hearing about their warranty. The technician arrived within the time slot, cleaned everything thoroughly, and even tested the cooling before leaving. Very professional service.
Grace Lee
My bedroom aircon used to make a weird noise at night. Booked a chemical overhaul on StringsSG and the noise is completely gone. The unit looks and works like it’s brand new. Highly recommend this service for older units.

What is Chemical Wash?
Over time, air conditioning units collect dust, mold, and bacteria, reducing cooling efficiency. A chemical wash eliminates these contaminants and restores your unit's performance.
The Benefits:
- ✔️ Improves cooling efficiency
- ✔️ Removes bacteria, mold, and allergens
- ✔️ Prevents aircon leaks and water blockages
- ✔️ Increases energy efficiency and lowers bills
- ✔️ Extends the lifespan of your aircon unit
Recommended Frequency: Every 6–12 months for optimal performance.
What is Chemical Overhaul?
An aircon chemical overhaul is a comprehensive deep-cleaning service where the entire unit is dismantled and each part is individually treated with specialized chemical solutions. This process targets deep-seated dirt, internal mold, and stubborn blockages that affect long-term performance.
The Benefits:
- ✔️ Restores aircon performance by removing internal build-up
- ✔️ Eliminates foul smells caused by mold and bacteria
- ✔️ Reduces persistent water leakage and drainage blockages
- ✔️ Enhances cooling efficiency, especially in older units
- ✔️ Extends lifespan of heavily-used or neglected aircon systems
Recommended For: Older, heavily used units or systems showing signs of deep blockages, weak cooling, or foul smells.
