For long-term performance and deeper cleaning, a chemical overhaul offers better value compared to a standard 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.
Recommended Frequency: Every 6–12 months for optimal performance.
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.
Recommended For: Older, heavily used units or systems showing signs of deep blockages, weak cooling, or foul smells.
Many customers ask about the difference between these two services. Here's a quick comparison:
| Feature | Chemical Wash | Chemical Overhaul |
|---|---|---|
| Cleaning Intensity | Moderate | Deep Cleaning |
| Components Cleaned | Filters, Coils, Drain Pan | Entire Aircon Unit |
| Best For | Regular Maintenance | Severe Mold & Blockages |
| Dismantling | Partial | Complete |

Real feedback from homeowners and businesses who trust StringsSG for aircon servicing in Singapore. Quality, speed, and customer satisfaction — all in one place.
At first, I was skeptical about using StringsSG, but then my friend recommended using the app. The aircon service booking on the app was super easy and instantly got a technician assigned. The servicing price is also quite reasonable.
Last time I always tried to search for aircon service company in google and then WhatsApp for quotations. Sometimes, no response, sometimes I must wait for the whole day to get a response. The quotations also keep changing every time. I started using StringsSG recently and I must say the quotation generates on the fly depending on whether I want 2 or 3 aircon unit to be serviced. The pricing is very good also. Must try.
Having moved to Singapore recently, it has been a pain to find services online. StringsSG is the first online portal I used to get my air conditioner serviced. So far, so good, I have got no complaints. I love their live chat application which has helped me to interact with the assigned service provider, especially when I need to reschedule.
I have always used StringsSG app for other services. I also got my personal trainer from the platform. The aircon service booking is also good and very fast. It works like Grab or GoJek. I like that my credit card is charged after the servicing is complete. On my last booking, the technician also found out that the gas level was low, so he helped to refill.
The app is good. If I don't like the auto-generated quotation, I don't need to proceed, but usually the pricing is very good. Maybe they can give some discounts and offer royalty program for returning customers.
Tried booking an aircon servicing through StringsSG after reading the reviews. Honestly, I was surprised at how seamless everything was. No need to call or WhatsApp anyone — just select the service and confirm. The technician came on time and even gave me tips on how to maintain the unit better. Definitely using again!
