What is R410A refrigerant?

R410A is a refrigerant blend composed of hydrofluoroolefins, used as the standard charge in most air conditioning systems installed across Perth from the mid-2000s through to the early 2020s. It replaced older ozone-depleting chlorofluorocarbon and hydrochlorofluorocarbon refrigerants and was long considered the industry standard for residential and light commercial cooling applications.

From 1 January 2023, the Australian Government prohibited the import of virgin R410A refrigerant as part of scheduled Ozone Layer Protection phase-down commitments. Existing systems that use R410A can continue to operate and be serviced with recovered or recycled refrigerant, but new installations and major retrofits must use lower global warming potential (GWP) alternatives such as R32 or R454B.

For air conditioning contractors in Perth, understanding R410A remains essential because thousands of functioning systems still contain it. Servicing these systems requires proper recovery, handling, and licensing under environmental protection regulations. Technicians must distinguish R410A from newer refrigerants to avoid mixing charges and to source compliant reclaimed stock when top-ups are needed. When systems reach end-of-life, contractors must arrange proper refrigerant recovery rather than venting.

If your air conditioner was installed before 2023, it likely uses R410A. Find licensed air conditioning repair providers who are equipped to service and maintain these systems correctly.
