MINUSR32-4.5KG Genuine HyChill Minus R32 Refrigerant 4.5kg for R32 Air Conditioning Systems, Licensed Technicians Only

MINUSR32-4.5KG is HyChill's Minus R32 refrigerant in a 4.5kg size, listed for air conditioning systems that run on R32. The quantity suits technicians who service several R32 split systems and want more on hand than a small can holds. It is a trade product for licensed technicians only, and the safety data sheet should be read before the container is opened.

Recharging R32 air conditioners after a leak repair

Most split systems installed in recent years run on R32, which replaced R410A in new equipment thanks to its lower global warming potential. When an R32 system loses gas, the signs are weak cooling or heating, ice on the indoor coil or pipework, longer run times and higher power bills. The leak has to be found and repaired first, then the system pressure tested, evacuated and charged by weight to the figure on the outdoor unit's label. Adding gas without fixing the leak only delays the next breakdown and releases more refrigerant.

Questions about this part

Can I top up my own split system with this?

No. In Australia, opening an air conditioning system or adding refrigerant requires a licensed technician with the right equipment. If your system has stopped cooling, book a licensed technician to find and repair the leak first.
