Nitrogen pressure testing
The system is held under pressure to confirm whether it leaks and roughly where before anything is opened.
Aircon Gas Refill & Leak Repair, Randburg & Sandton
Air conditioners are sealed systems — they do not use gas up, they lose it. Anyone who tops your unit up without finding the leak is selling you the same repair again next season. We pressure test, trace the leak, repair the joint or component, then recharge to the manufacturer's stated weight.
What this covers
Leak tracing
Electronic detection and UV dye where needed, including flare joints, Schrader valves and corroded coils.
Flare and joint repairs
Re-flared and re-brazed connections, the single most common cause of gas loss in retrofitted splits.
Correct-weight recharging
R22, R410A and R32 charged by scale to spec, not by guesswork, so the compressor is not stressed.
Vacuum and moisture removal
Systems are evacuated properly before charging so moisture does not destroy the compressor oil.
SAQCC-compliant handling
Refrigerant recovered and handled by registered technicians, never vented to atmosphere.
What it costs
Regas pricing depends on refrigerant type and system size — R22 is the most expensive because it is being phased out. Leak repair is quoted separately once traced, and we always quote both before starting.
See full pricing guidance →Questions we get asked
How often should an aircon need gas?
Never, in a healthy system. If your unit needs gas more than once, there is a leak and it should be traced rather than repeatedly topped up.
Do you still work on R22 systems?
Yes, though R22 is being phased out and is increasingly costly. On badly leaking older units we will compare the regas cost against a replacement honestly.
How long does a regas take?
A straightforward pressure test and recharge takes about two hours. Leak repairs add time depending on where the fault sits.
