Aircon Gas Top-Up Services In Singapore

By StringsSG – Your Local Home Service Partner

Air conditioning systems require refrigerant gases like R22, R410A or R32 to function effectively. Low gas levels cause poor cooling and increased electricity bills. Our experienced technicians use gauges to identify and refill gas levels safely during regular servicing.

If you're on a maintenance package, refrigerant level checks are included. Refills are charged separately based on gas type.

Stephen Ng

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.

Melissa Choo

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.

Richard Pink

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.

Naveen Reddy

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.

Clarissa Lim

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!

Types of A/C Refrigerant Gas

R22 gas cylinders

Performing an aircon chemical wash yourself can be complex and dangerous as it involves handling chemicals and electrical components. It's best to hire professionals with the proper tools and safety knowledge. If you still wish to proceed DIY, please be cautious and informed.

1. R-22 (Chlorodifluoromethane)
Once widely used, R-22 is being phased out globally due to ozone depletion issues under the Montreal Protocol.
2. R-410A (Puron)
R-410A replaced R-22 in many systems. It's more environmentally friendly as it doesn’t deplete the ozone layer.
3. R-134a (1,1,1,2-Tetrafluoroethane)
Used in automotive and commercial systems, R-134a has no ozone depletion effect but contributes to global warming.
4. R-407C
Designed to replace R-22 in existing systems, R-407C is ozone-safe but still contributes to global warming.
5. R-32 (Difluoromethane)
Common in newer residential units, R-32 offers lower global warming potential compared to many HFCs.
6. R-290 (Propane) and R-600a (Isobutane)
Eco-friendly hydrocarbon refrigerants with very low global warming impact, used in small-capacity systems.

Refrigerant use and availability are changing due to evolving regulations and environmental concerns. Stay updated with newer, safer alternatives.
