Aircon gas leak diagnosis and repair in Tampines

A gas top-up on its own only refills refrigerant, it does not fix why the gas ran low in the first place. If a unit needs topping up again within months of the last one, that points to a leak somewhere in the line, coil, or joints, and this is a distinct job: leak detection (often using soap water, nitrogen pressure test, or an electronic sniffer) followed by sealing or replacing the leaking section before any regas happens.

Skipping the leak check and just topping up repeatedly wastes money and refrigerant, and in Tampines' older condo and HDB stock, corroded copper piping or a bad flare joint from a previous install are common culprits.

• Ask whether leak detection is included in the callout or charged as a separate diagnostic step
• A proper job seals or replaces the leaking section before adding new gas, not just refills and leaves
• Repeated low-gas symptoms (icing, weak cooling, hissing sounds) are signs to ask for a leak check, not just a top-up
