Why is nitrogen equipment essential for HVAC systems?

Nitrogen plays a critical role in HVAC system installation and maintenance. It prevents atmospheric oxygen from creating damaging oxides in the system's copper coils and piping. These oxides can seriously damage the compressor and other components, which is why you need to purge HVAC system lines with professional nitrogen equipment.

Nitrogen also drives out moisture that causes corrosion in metal components. Using it to pressure-test coils and AC lines is the most effective way to detect leakage before sealing an HVAC system, saving time and money and ensuring long-term reliability.

Purging HVAC system lines with professional nitrogen equipment is a necessary step that no installer should skip.
