Absolute Aircon Regas Across Gauteng: Gas Leak Detection & Installation
Same-day service On-site repair Call 072 686 0472
If your aircon is running but blowing air that isn't cold, it may be low on gas. We find out why it lost the gas, fix the leak, and regas it to the manufacturer's specification, at your home or business anywhere in Gauteng.

An aircon is a sealed system, so it only runs low on gas when there is a leak. A proper regas means connecting gauges to check the pressures, finding and repairing the leak, pressure-testing, vacuuming the system and then charging it with the correct gas (R32 or R410a on most modern splits) to the manufacturer's specification. Topping up without fixing the leak only works for a while. We regas split aircons across Gauteng: a flat R350 call-out to diagnose, waived if we do the repair, then a fixed price before we start.

Signs your aircon is low on gas
- It runs, but the air coming out is only cool, or not cold at all.
- It takes much longer than it used to to cool the room, or never gets there on a hot day.
- Ice or frost forms on the thin copper pipe at the outdoor unit or on the indoor coil.
- The outdoor unit runs for long periods without the room cooling down.
- It needed a regas before, and now it is losing its cooling again.
Other faults can look similar: blocked filters, a dirty coil, a failed outdoor fan motor or a faulty capacitor can all stop an aircon cooling. That is why we test first instead of just adding gas. Our guide to an aircon not cooling covers the other causes.
Why an aircon loses gas
The gas in an aircon isn't used up like fuel. It goes round and round in a closed loop, so if the level is low, it has leaked out somewhere. The usual places are:
- Flare joints where the pipes connect to the indoor and outdoor units, especially if they weren't made up properly on installation.
- Aluminium pipework, which is more prone to corrosion and cracking than copper, especially outdoors.
- Corroded coils, particularly outdoor units in exposed or polluted spots.
- Vibration and rubbing, where a pipe touches the casing or a bracket and slowly wears through.
Gas leak detection and regas: how we do it
- Check it properly. We connect our gauges to the outdoor unit, read the pressures and rule out the other causes of poor cooling.
- Find the leak. We check the joints, the pipework and the coils to find where the gas is escaping.
- Repair it. Remaking a flare joint, replacing a damaged section of pipe, or repairing or replacing the leaking part.
- Pressure-test and vacuum. We test that the repair holds, then pull a vacuum to remove air and moisture from the system.
- Charge to spec. We fill it with the correct gas for that unit to the manufacturer's charge, then run it and check it is cooling properly.
We regas modern R32 and R410a units. If an older aircon still runs on R22 gas, it is usually better value to replace it with a modern inverter unit, and we will tell you honestly if that is the case.
Real aircon regas jobs
These are recent regas jobs done by our technicians, with photos from the job.
Krugersdorp: leaking aluminium line replaced with copper
An aircon on a double-storey home in Krugersdorp had lost its gas and stopped cooling. We traced the leak to the liquid line, which had been installed in aluminium, replaced it with copper pipe, pressure-tested the joints, vacuumed the system and regassed it. It was cooling at full strength again.
Benoni: low gas found on a service
During a full service on a Samsung Digital Inverter aircon in Benoni, our gauges showed the gas pressure was low. We regassed it to the correct charge and tested it cooling properly.
Sandton: service and regas before summer
A Samsung Digital Inverter split in a Sandton bedroom had a full service ahead of the hot months. Outside, we checked the gas pressures with our gauges, regassed it to the correct charge and tested it on cooling.

Aircon installation
We also supply and install split aircons across Gauteng, from single bedroom units to multi-room and office installs. On every installation we pressure-test the pipework, vacuum the system and check every joint for leaks before we switch it on, because a careful install is the best way to avoid needing a regas later. Back-to-back installs start from R1,650, with a free service six months later. See aircon installation in Gauteng for prices and recent installs.
What does an aircon regas cost?
Every job starts with a flat R350 call-out to come out and find the fault, and it is waived if we go ahead with the repair. After that, you get one fixed price before we start. The price depends mostly on where the leak is and what it takes to fix it: a flare joint is a smaller job than a section of pipe high up an outside wall or a leaking coil. For typical ranges, see our repair cost guide.
Where we regas aircons
We work across Gauteng: Kempton Park, Johannesburg, Sandton, Randburg, Fourways and Midrand, Pretoria and Centurion, the East Rand including Bedfordview, Benoni and Boksburg, and the West Rand including Roodepoort, Krugersdorp and Randfontein. See aircon repair in Gauteng for everything else we do on aircons, from servicing to installations.
Fridge or cooler not cooling?
We also find and repair gas leaks on fridges, freezers, bar fridges and display coolers, then regas them. See fridge not cooling.
Frequently asked questions
How do I know if my aircon needs a regas?
If it runs but the air isn't cold, takes much longer to cool the room, or you see ice on the pipes or coil, it may be low on gas. Blocked filters, a dirty coil or a failed fan can look the same, so we check with gauges before adding any gas.
How often should an aircon be regassed?
Ideally never. An aircon is a sealed system and doesn't use up its gas, so if it needs a regas, there is a leak. If yours needs gas again within months, the leak should be found and repaired rather than topped up again.
Do you regas R32 and R410a aircons?
Yes. We regas both R32 and R410a split units, after finding and repairing the leak that caused the gas loss. Older units on R22 gas are usually better replaced with a modern inverter unit.
Can you do the regas the same day?
Often, yes. If the leak is at a joint or in pipework we can reach and repair on site, we fix it and regas on the same visit. If a part such as a coil needs to be ordered, we give you a fixed price first and come back to finish the job.
How much does an aircon regas cost?
There is a flat R350 call-out to diagnose the fault, waived if we do the repair. Then you get a fixed price before we start, which depends mostly on where the leak is and what it takes to repair it.
