Copper Line Set excellent: Not All Copper Is established equivalent
The expression “copper line set” sounds straightforward, but listed here’s the catch: copper purity and production criteria range wildly. Cheap imports typically use recycled copper with impurities that weaken the tubing and make it liable to pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s manufactured to the highest HVAC sector typical for seamless copper tube. That interprets into:
-
greater burst stress tolerance (critical for contemporary significant-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, especially in coastal or industrial locations.
