The Great R22 Refrigerant Phase-out

The R22 Refrigerant Phaseout

The R22 Refrigerant Phaseout

Earth's Ozone Layer has been taking a beating for a long time from ozone depleting substances including refrigerants. The older refrigerants used in air conditioning and refrigeration systems cause widespread damage to the ozone layer and have even caused a hole in layer over the South Pole. In recent years, many countries have signed numerous pacts to reduce and phase out the use of environmentally unfriendly refrigerants.

Refrigerants which contain chlorine as part of the chemical makeup are one of the leading causes of global warming and ozone depletion. R22 is a HCFC refrigerant which contains chlorine and therefore is damaging to the environment.

Much of the refrigeration and air conditioning equipment in use today utilises the R22 refrigerant. With the phaseout in progress now, more and more manufacturers are beginning to cease production of compatible parts and materials. It is inevitable that eventually, replacement refrigerant and parts will become unobtainable.

The Replacement Refrigerant R410a

R410a is fast becoming the most widely used refrigerant for all new makes and models of air conditioning systems. The reason being is that R410a is a HFC which does not contain chlorine as part of it's chemical makeup. The new R410a doesn't cause damage to the ozone layer.

However, the replacement has one drawback. To achieve the same amount of cooling, higher system pressures are required. This means that it is not suitable as a direct drop-in replacement for the older R22 systems. When R22 is no longer available, systems will have to be upgraded rather than repaired.

When you air conditioning installation is beyond repair, we recommend upgrading to a newer system which utilises the ozone friendly R410a freon. Doing so will also ensure that you don't get lumped with a roof full of unrepairable air conditioning systems. Save the environment and use R410a in all your future air conditioning installations.
