What Is Brazing?
Brazing is a method used when connecting refrigerant tubing in the process of repairing or installing HVAC equipment. Brazing ensures that the connections do not leak and helps strengthen the joints, making them able to withstand high pressure and temperatures.
Importance of Brazing
Brazing is a metal-joining process that involves fusing two or more metal parts by heating them to a high temperature and using a filler metal to form a strong, permanent bond. This process is crucial in HVAC installations, as it ensures that the connections between copper pipes do not leak and the joints are strengthened to withstand high pressure and temperatures.
Properly executed brazing creates a reliable and durable seal, preventing any potential leaks or failures in the HVAC system. This helps maintain the system's efficiency and prevents costly repairs or replacements down the line.
What Is Nitrogen Purging?
Nitrogen purging is a task performed during brazing which helps ensure your HVAC system runs smoothly and without issue. Almost every HVAC installation requires flowing dry nitrogen through the copper pipes during brazing to prevent oxidation.
The Role of Nitrogen Purging
Nitrogen purging is a technique used during the brazing process to create an inert environment and prevent the formation of oxides on the metal surfaces. By flooding the work area with nitrogen, the risk of oxidation and contamination is significantly reduced, ensuring a strong and long-lasting brazed joint.
Nitrogen purging also helps protect the integrity of the copper pipes and other HVAC components, preventing any potential compromises that could lead to system failures or reduced performance over time.

Why Are These Steps Important?
The importance of brazing and nitrogen purging when installing new HVAC equipment cannot be overstated. But ensuring the process is done correctly is just as important.
That includes making that nitrogen is properly introduced into your HVAC system at the correct flow rates. If brazing and nitrogen purging is not done correctly, the joints could be easily weakened and unable to withstand the pressure and/or heat coming through the copper pipes.
