Aircon gas leak detection
We confirm the leak and find where it's escaping before any repair, so you stop paying for top-ups that don't hold. We’ll assess first, then confirm whether this is the right scope before you book.

What gas leak detection covers
Low refrigerant is a symptom, not the fault. Topping up without finding the leak means paying again in months. We confirm the gas is actually dropping, then track down where it's escaping, so the repair fixes the cause instead of refilling around it. Common situations where leak detection fits:
Gas dropped again within months
Repeated top-ups mean refrigerant's escaping somewhere in the circuit.
System is completely empty
A full loss needs the leak found before recharging, or the new gas escapes again.
Leak risk after piping or relocation work
A pressure test confirms the joints and pipe run hold before we charge the system.
When gas leak detection isn't suitable
Hunting for a leak isn't the first move for every weak-cooling complaint.
Pressure dropped slowly over several years
A measured gas top-up's usually enough if the system has held charge for a long period.
Pressure is normal but cooling is weak
The fault's more likely airflow, compressor, sensor, or control related, not a leak.
The leak point is already obvious
Visible oil or ice at a specific joint often means we can quote the repair directly, without a full detection.
What you get
Stop repeat top-ups by proving whether the system's leaking and where.
Leak confirmed before repair
You don't pay for leak repair when the gauges and tests show the system's holding.
Fault location identified
Joint, valve, coil, or pipe run narrowed down before any repair is quoted.
Retest after repair
After the fix, we pressure-test again and confirm it holds before recharging.
How gas leak detection works
Confirm the drop, check the easy points, then isolate the line. From your first message to a system that holds, here is what happens.
You message us
Tell us the symptom: repeated top-ups, cooling that fades a few months after a recharge, or a leak check after piping work. We come back with the likely causes.
We assess on-site ($30)
We put gauges on the system to confirm the charge is actually low, then soap-test the easy suspects, the flare joints and service valves. The $30 rules out work you don't need.
We locate the leak
If the accessible joints are clean, we pressure-test with dry nitrogen to find which line or section won't hold, the slow leaks a top-up just hides.
We explain and quote
Plain language: where it's leaking and what the fix takes, a joint reseal, a pipe section, or a coil. Nothing goes ahead without your say.
We repair and retest
The $30 comes off the work. We fix the cause, pressure-test again to confirm it holds, then recharge with the correct refrigerant.
What we check before quoting
Leak detection is a sequence of methods, not a single test. We work from the cheapest, fastest check to the most thorough.
Confirm the drop
Gauges tell us whether the charge is genuinely low and how far it's fallen, before we go hunting for a leak.
Check the accessible joints
A soap test on the flare joints and service valves catches the leaks sitting at the connections we can reach.
Pressure-test to find the line
If the joints are clean, dry nitrogen at controlled pressure isolates which line or section is losing pressure, the hidden leaks behind walls or in the coil.
Locate, then quote
We only quote the repair once the leak's location and access requirements are clear.

Workmanship warranty
We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.
Labour
30-day labour warranty. If the same fault returns from the repair we did, we come back and the labour is on us, with no second diagnosis fee.
Parts
Parts follow whatever warranty the distributor sets for that component, so the term varies by part. We tell you the coverage before you approve the quote.
Documented leak detection cases
Real diagnosis work, not generic service claims. Open the case if the symptom looks familiar.
