Initial diagnosis
Checks whether the symptom is more consistent with refrigerant loss, airflow restriction, controls or another fault. It establishes the next test; it does not promise a located leak.
Quick answer: what should you budget first?
FixMove's current planning band for an initial aircon fault assessment is S$60–S$80. That is not an all-in gas leak repair price. If refrigerant loss remains a likely cause, the leak-testing method, access, repair and any post-repair refrigerant are scoped and quoted separately.
For recharge planning only, current starting points are R32 from S$80, R410A from S$120 and R22 from S$150 per system. Refrigerant type and amount must be confirmed from the nameplate and diagnosis. See the dedicated aircon gas top-up cost guide for that separate price intent.
Symptoms are clues, not confirmation. Weak cooling, ice or a hissing sound can also come from airflow, control or component faults. A diagnosis-first quote helps prevent a refill being treated as the default repair.
Aircon gas leak detection cost and quote boundaries
The first amount is a planning band for assessment. A valid comparison quote should then show whether focused leak testing, opening up access, repairing a component and recharging the system are included or excluded.
| Scope item | Planning price | What changes the quote | Boundary to confirm |
|---|---|---|---|
| Initial fault assessment | S$60–S$80 | System layout, number of affected units, symptoms and condenser access | Does not automatically include focused leak testing, repair or refrigerant |
| Focused leak testing | Quoted by scope | Testing method, accessible joints, concealed pipework and number of circuits | Ask which system and areas are included, plus what result will be recorded |
| Leak repair | Quoted after location | Leak location, component or pipework affected, access and required materials | Approve the repair only after an itemised scope is provided |
| Refrigerant recharge after repair | R32 S$80 / R410A S$120 / R22 S$150 starting points | Nameplate refrigerant, required amount, system condition and recharge procedure | Starting price per system, not the total leak-detection and repair bill |
Planning figures are not a fixed quotation. Ask for diagnosis or call-out, leak testing, access, repair, refrigerant type and amount, labour and final checks to be itemised before approval.
Diagnosis, leak testing and repair are different decisions
A diagnosis-first path keeps a suspected refrigerant leak distinct from routine aircon servicing and broad fault repair.
Focused leak testing
Defines the system and suspected areas to be tested. The method and access scope should be confirmed because visible joints and concealed pipework are not the same job.
Repair and recharge
Begins only after the location, repair scope and price are approved. Refrigerant is then a separate item based on the system nameplate and required amount.
When a refrigerant leak assessment makes sense
Useful reasons to request diagnosis
- Cooling drops again after an earlier refrigerant top-up.
- Ice forms on pipework or the indoor unit while airflow and cleaning have already been considered.
- A hissing sound or visible oil-like residue appears near accessible refrigerant joints.
- One system repeatedly underperforms while other systems at the property cool normally.
- A prior visit identified low charge but did not document the cause.
Reasons not to assume “gas leak”
- Dirty filters, coils or restricted airflow can also cause weak cooling and icing.
- Sensors, controls, fans and compressor faults can overlap with low-refrigerant symptoms.
- Water dripping from the indoor unit usually belongs on the aircon water-leak diagnosis path, not this refrigerant page.
- For general weak cooling with no prior refrigerant history, start with the aircon not cold guide.
From symptom to an itemised repair decision
This process describes scope and approval points. Actual testing and repair depend on the system, access and findings.
Send system evidence
Share the outdoor-unit nameplate, affected rooms, symptoms, prior top-ups or repairs, postcode and condenser access.
Confirm visit scope
Clarify how many systems are included and whether the first amount covers assessment only or any focused testing.
Diagnose on site
Separate possible refrigerant loss from airflow, control and component faults before choosing the next test.
Review the quote
Ask for testing method, access, repair, refrigerant and final checks to appear as separate line items.
Approve selected work
Proceed only with the agreed repair and recharge scope, then retain the documented system and refrigerant details.
Details that make leak-detection quotes comparable
System identity
Send a clear outdoor-unit nameplate, brand, model, refrigerant type if legible, number of fan-coils and which rooms are affected.
Fault history
State when cooling changed, whether icing or sounds occur, any error code, and the dates and outcome of earlier top-ups or repairs.
Property and access
Include property type, postcode, condenser location, whether pipework is concealed and any known access restrictions.
How Singapore official guidance applies
These sources support maintenance, refrigerant-handling and exterior-unit safety boundaries. They do not set FixMove's leak-detection prices and do not prove that a specific symptom is a refrigerant leak.
- NEA: refrigerants in the refrigeration and air-conditioning sector NEA identifies household refrigerant competency training and states that, for R32 systems, manufacturers must ensure service personnel complete ITE training to comply with SCDF requirements. Confirm the refrigerant type and assigned scope; this page does not claim a technician credential.
- NEA: household air-conditioner energy-saving tips NEA recommends checking filters monthly, cleaning or replacing them when necessary, regular servicing and annual inspection. That supports maintenance planning, but it is not a gas-leak test or repair-price standard.
- BCA: air-conditioning unit and structural-support safety BCA guidance is relevant to exterior or projecting units, their supports, and installation or retrofit work. It does not set the price for routine leak diagnosis. If support or installation work is needed, confirm the trained-installer and structural scope separately.
Aircon gas leak detection FAQ
How much does aircon gas leak detection cost in Singapore?
FixMove's current planning band for an initial aircon fault assessment is S$60–S$80. Leak testing, leak repair, access work and refrigerant are not included automatically; each is quoted after the system, suspected leak area and testing method are confirmed.
Does weak cooling prove that the aircon has a gas leak?
No. Weak cooling, icing, hissing or repeated refrigerant loss can justify testing, but dirty filters, restricted airflow, sensors, controls and compressor faults can produce similar symptoms. Diagnosis comes before a leak-repair quote.
Is gas leak detection the same as a gas top-up?
No. Detection establishes whether refrigerant is being lost and, where practicable, where. A top-up only adds refrigerant. Leak testing, repair and recharge should appear as separate line items.
Can refrigerant be topped up without repairing a leak?
If a leak is confirmed, adding refrigerant without addressing the cause may lead to repeat loss. The repair scope and post-repair recharge should be approved separately; a sealed system should not need scheduled top-ups.
What should I send for a leak-detection quote?
Send the outdoor-unit nameplate, brand and model, affected rooms, symptoms, previous top-up or repair history, photos or error codes, property type, postcode and condenser access details.
When are BCA air-conditioning rules relevant?
BCA guidance is relevant when an outdoor unit projects from a building or work involves its support, installation or retrofit. It is not a price standard for routine leak diagnosis; if structural-support or installation work is needed, the required trained installer and scope must be confirmed.
