All Heating, cooling, and refrigerationtechnicians use nitrogen. Nitrogen is a noble gas and prevents copper pipes from oxidizing while brazing. It is also used to check systems for leaks. Leak testing with nitrogen can save loss of expensive refrigerant which is illegal to vent to the atmosphere. It's all so a dry gas containing almost no moisture so it can help to purge moisture from system that contains moisture. That being said, nitrogen can not be used in a operational systems. Home AC systems and refrigeration systems can not use nitrogen to cool. It will damage the compressor. Also onlylicensed techs should work on AC systems.
