Which types of refrigerants should I avoid and which ones are preferred?
• Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect. Production of new stocks ceased in 1994.
• Hydrochlorofluorocarbons (HCFCs), including R22. Slightly less damaging to the ozone than R12, but the EPA has still mandated a phase out as a result of the Clean Air Act of 2010. R22 will phase out completely by 2020.
• Hydrofluorocarbons (HFCs), including R410A and R134. With no chlorine in the mix, this is safer for the environment and is now being used in place of R22. Air conditioners that run on R410A are more efficient, offer better air quality, increase comfort and improve reliability.
HFCs are therefore the best choice for both efficiency and for the environment.
