Do I need to worry about the refrigerants used?

Certain appliances, such as air conditioners contain chemicals Hydrochlorofluorocarbons (HFCs) including R22. This almost odorless and tasteless gas can cause severe symptoms if a person inhales too much at once and is dangerous for the environment.
HFCs are being phased down in Australia (from 2018) and globally under the Montreal Protocol (from 2019), as they generally have a high global warming potential.
If you have an air conditioner manufactured before 2010 you should be aware of what type of refrigerant it uses. If your older system develops a leak, it may need to be recharged with more refrigerant. 
Be sure you know which refrigerant is being used and that it is approved
