R22 Gas - The EU law

Have you replaced
the R22 gas

in your air conditioning units?


Replacing the R22 Gas in Air Conditioning Units

In recent years, owners of air conditioning units may have become aware of 2000 EU legislation regarding the traditional R22 gas no longer being used and completely banned as of 2015. As the R22 phase-out reaches its end in the next few years, alternatives such as the R410a are being introduced. This is a blend of HFCs which are not considered to contribute to the depletion of ozone.
