It depends on where you are located and the type of air conditioner that you currently have. At the moment, the EU Commission, EFCTC and refrigerant industry are raising awareness and exercising authority where possible to encourage a joint approach to stamping out banned refrigerants. This is because an R134A systm converts between gas and liquid at a vastly different temperature than R22.

At the very least, its going to be increasingly expensive. It is also an offence to manufacture or import refrigeration and air conditioning equipment . The major reason is that R22 is illegal to produce now. You may also notice that it can be exceedingly difficult to find an R22 replacement. Phasing Out HCFC Refrigerants To Protect. It is important to remember that if you add R-407C to the system, the system will need to be emptied beforehand. The development of MVAC systems using lower-GWP refrigerants has been encouraged by MVAC refrigerant requirements in Europe, where the EU Directive on Mobile Air Conditioning (MAC Directive) mandates transition to a refrigerant with a GWP below 150 by January 1, 2017, and in the United States by the availability of credits under the MY 2017-2025Light-Duty Greenhouse (LD GHG) Rule (77 FR 62624, October 15, 2012). HFCs are intentionally-made fluorinated greenhouse gases used in the same applications where ozone-depleting substances have been used, including motor vehicle air conditioning. Barring that, ask your HVAC technician the next time you have the unit checked out. These effects include increases in cataracts, skin cancer, and weakened immune systems.
