Here is one effective technique for repairing smaller copper lines—along with a clear visual demonstration of why flowing nitrogen is critical every single time you braze (cupric oxide forms internally without it!). ​Whenever a refrigerant system is opened up, standard trade practice requires replacing the liquid line filter drier. Follow that up with a deep vacuum, verify system tightness, and use proper charging practices to prevent non-condensables from ruining efficiency. ​Have a great weeke

One small step that makes a big difference. Flowing nitrogen while brazing prevents oxidation inside the copper lines so debris doesn’t contaminate the refrigeration circuit. Cleaner installs mean better performance and longer system life.

Flowing nitrogen while brazing is EXTREMLY important!!! The oxidation will build up inside the pipe and be striped off by the POE oil. It will then flow around the system until it gets causes a restriction somewhere. #hvaclife #hvactechnician #hvacservice #hvacinstall #love2hvac #flownitro | Ty Branaman
