Aircon Pressure Test Cost and Gas Leak Guide Singapore
A gas top-up changes the refrigerant charge; it does not prove why refrigerant was lost. This guide explains the evidence a pressure test can provide and the quote lines to separate before work starts.
Quick answer: FixMove lists an initial aircon fault assessment at S$60–S$80. Focused leak testing, access, repair and refrigerant recharge are separately quoted because the number of fan-coils, pipe route and test access differ. A controlled pressure test can indicate whether an isolated circuit is losing pressure; it may not identify the exact leak point without further joint checks or section isolation.
What the first S$60–S$80 covers—and what it does not
The initial figure is for fault assessment, not an all-inclusive leak-repair package. A useful written quote separates diagnosis from the corrective work so you can see what you are approving.
| Quote line | Purpose | Price treatment | Confirm in writing |
|---|---|---|---|
| Initial fault assessment | Check symptoms, basic operation and whether leak testing is justified | FixMove lists S$60–S$80 | What checks are included and whether another visit is likely |
| Focused leak or pressure testing | Test the relevant circuit or sections under controlled conditions | Separate job-specific quote | Units or sections covered, access assumptions and test method |
| Leak repair | Repair an accessible joint, pipe or component after the fault is located | Separate labour and materials | Exact repair point, replacement parts, exclusions and warranty |
| Evacuation and recharge | Prepare the repaired system and restore the specified refrigerant charge | Separate unless explicitly bundled | Refrigerant type, quantity basis and post-repair checks |
| Access or making good | Reach concealed pipework, high condensers or closed ceiling spaces | Site-dependent | Opening, access equipment and reinstatement responsibility |

Symptoms that do not prove a gas leak
Weak cooling, icing, hissing and repeat loss of performance can justify investigation, but none of them alone proves that refrigerant is escaping. Airflow restrictions, dirty coils or filters, fan faults, sensors, controls and equipment sizing can create overlapping symptoms.
- One room is weak: compare airflow, set point and fan operation before assuming a shared refrigerant problem.
- Several fan-coils weaken together: record when it began and whether the outdoor unit runs normally.
- Cooling improves after every top-up, then fades: ask for the underlying fault to be investigated instead of treating repeated recharge as a repair.
- Ice appears: switch off cooling if continued operation is unsafe or water is spreading, let the unit thaw and keep water away from electrical points.
How a controlled pressure-test workflow is scoped
- Confirm system details. Record the indoor and outdoor model numbers, number of connected fan-coils and refrigerant type.
- Assess the operating fault. The technician checks whether the symptom supports a refrigerant-circuit investigation or points elsewhere.
- Define the test boundary. Depending on the equipment and manufacturer procedure, the relevant circuit or section is isolated and tested under controlled conditions.
- Monitor and inspect. Stable conditions matter. Joints, valves, accessible piping and coils may need separate checks; a pressure change can establish loss without immediately revealing the exact point.
- Quote the repair. Access, parts, pipework and making-good are confirmed before corrective work.
- Restore and verify. After an approved repair, the system is prepared, recharged to the applicable specification and checked again for normal operation.

Need the leak-test scope itemised?
Send the model labels, affected rooms, symptom timeline and access photos. FixMove will separate the initial assessment from focused testing, repair, refrigerant and access items before approved work proceeds.

How much does an aircon pressure test cost in Singapore?
FixMove lists an initial aircon fault assessment at S$60 to S$80. Focused leak testing, access, repair and refrigerant recharge are separate scopes and must be quoted for the actual system; the assessment figure is not a promise that every pressure test is included.
Does weak cooling prove that the aircon is leaking gas?
No. Weak cooling can also result from airflow restrictions, dirty components, sensor or control faults, drainage issues and other causes. A technician should assess the system before recommending leak testing or refrigerant recharge.
Can a pressure test locate every refrigerant leak?
Not always in one step. A controlled test can show whether an isolated circuit is losing pressure, but the precise leak point may need joint checks, section isolation or another suitable detection method. Access and intermittent faults can extend the diagnosis.
Should refrigerant be topped up before the leak is repaired?
A recharge can restore the operating charge but does not repair a leaking joint, coil or pipe. If a leak is confirmed, ask for the repair, evacuation, recharge and post-repair verification to be itemised before approving work.
