They are gases that do not emit CFCs (chlorofluorocarbons), chlorine-based substances that are very harmful to human health and the environment, and which also damage the ozone layer, which is responsible for protecting the Earth against solar radiation. The most common types of greenhouse gases in air conditioners are R-410A and R-407C.
Green gas recharge: R410-A handling is similar to R-22. The difference is that the R410-A must be completely removed from the system for recharging. It is not recommended to only complement the gas load. The amount of gas will depend on the appliance and the manufacturer.
