HCFC-22 (also known as R-22 & to most consumers as Freon) has been the refrigerant of choice for residential heat pump and air-conditioning systems for more than four decades. Unfortunately for the environment, releases of R-22, such as those from leaks, contribute to ozone depletion. In addition, R-22 is a greenhouse gas and the manufacture of R-22 results in a by-product (HFC-23) that contributes significantly to global warming. As the manufacture of R-22 is phased out over the coming years as part of the agreement to end production of HCFCs, manufacturers of residential air conditioning systems are offering equipment that uses ozone-friendly refrigerants.
Many homeowners may be misinformed about how much longer R-22 will be available to service their central A/C systems and heat pumps.
R22 is a single hydrochlorofluorocarbon (HCFC) compound. It has low chlorine content and ozone depletion potential.
R22 will no longer be manufactured from year 2010. Only recycled or remaining stock of R22 can be used.
R1410a is an environmentally friendlier refrigerant which is Non-CFC. That meant that, if your system ever leaks, the escaping refrigerant won’t contribute to ozone depletion!
R22 refrigerant vs R410a refrigerant
There are two commonly used refrigerants used in air-conditioning, R22 & R410a. R410A was developed as a replacement to R22, which will be phased out in year 2020 in response to international environmental concerns.
Ozone Layer Depletion
It was discovered that the commonly used air conditioner refrigerant, R22 refrigerant, has a great responsibility on the ozone layer depletion. This bring the signing of the Montreal Protocol treaty. This bring the creation of R410a refrigerant which does not contribute to ozone depletion.
The Montreal Protocol on Substances That Deplete the Ozone Layer is an international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. The treaty was opened for signature on September 16, 1987.
