-
employing leftover tubing from A further work (previously contaminated with humidity or particles).

Copper Line established excellent: Not All Copper Is Created Equal
The term “copper line set” sounds easy, but in this article’s the catch: copper purity and production specifications differ wildly. low-cost imports usually use recycled copper with impurities that weaken the tubing and allow it to be prone to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s built to the highest HVAC field typical for seamless copper tube. That translates into:
-
increased burst strain tolerance (vital for contemporary large-force refrigerants like R-410A and R-32).
-
greater corrosion resistance, especially in coastal or industrial places.
