Guide · Published 15 October 2026
Reviewed and approved by a NearbyWise editor before publishing. Every fact is checked against the business's own website. How we check
An aircon gas top-up replaces refrigerant that a system has lost so that it can cool properly again. Because refrigerant circulates in a sealed loop, a unit that keeps running low may have a leak worth investigating. This guide sets out the gas top-up prices stated by ten Singapore aircon companies, listed in the order produced by our ranking method. Prices may be quoted per top-up, per unit or by refrigerant type, such as R22, R410A and R32. Check which refrigerant your unit uses and ask for a firm quote before booking.
