Gas leak & leakage repair service — most leaks cost only the top-up: R22 $115 / R410A $130 / R32 $170 · 90-day workmanship warranty
Most aircon gas leak repairs at aircons.sg cost only the price of the gas top-up — R22 $115, R410A $130, R32 $170, flat — because the $45 visit and diagnosis fee is waived when you proceed. Where the leak needs piping or coil work, the published rates apply — piping replacement is $450 per FCU, with coil repair or concealed pipe work quoted after the test — before any work starts, and every repair is backed by a 90-day workmanship warranty. Whether you call it a gas leak or gas leakage, it is the same problem and the same price.

Refrigerant is not consumed the way fuel is. It circulates in a sealed loop between the indoor and outdoor units, and in a healthy system the same gas keeps circulating for the life of the aircon — it never needs topping up. So when a system is low on gas, the gas went somewhere: a loosened flare joint, a corroded coil, a pinhole in the piping.
That is why the honest question is never "how much does a top-up cost?" but "where is the gas going?" — and it is why we check the system's pressure before recommending anything.
Not every leak is urgent. A very slow leak may lose gas over a year or more, and an occasional top-up can genuinely be the practical choice — when that is the case, we say so. But a fast leak that empties the system in weeks means you are renting gas, not fixing your aircon: three or four top-ups can cost more than the actual repair.
The only way to know which kind you have is to check the system's pressure. The $45 visit fee covers the full 9-point pre-check and a gas pressure check, and it is waived when you proceed with a top-up, so there is no reason to guess. If a dedicated pressure / leak test of the piping set is needed to pinpoint the leak, that is $150 per FCU.
In most cases the repair costs only the flat top-up price, because the $45 visit and diagnosis fee is waived when you proceed: R22 $115, R410A $130, R32 $170 — nothing added. That covers the visit, the 9-point pre-check, the gas pressure check and the top-up itself.
Where the leak needs more than a top-up, the published rates apply: a dedicated pressure / leak test of the piping set is $150 per FCU (offset against the repair if you proceed on the same visit), a full piping replacement is $450 per FCU, and a re-made joint, a corroded coil or concealed pipe work is quoted upfront after the test. You see and approve every figure before any work starts. If you decide not to proceed, you pay only for the visit and any leak test already carried out — nothing towards the repair. Unrelated faults found during the pre-check, such as drainage or electrical issues, are standard repairs from $80.
We publish a flat piping replacement rate of $450 per FCU. Coil repair and concealed pipe work, which vary too much from home to home, are quoted after the pressure test — and that quote depends on:
Whatever the answer, you get the exact figure upfront after the pressure test — no work begins until you have agreed to the price.
