Copper Line Set Quality: Not All Copper Is made Equal
The phrase “copper line established” Appears uncomplicated, but here’s the capture: copper purity and manufacturing specifications range wildly. low cost imports generally use recycled copper with impurities that weaken the tubing and allow it to be susceptible to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s produced to the very best HVAC marketplace common for seamless copper tube. That translates into:
-
larger burst force tolerance (essential for contemporary higher-pressure refrigerants like R-410A and R-32).
-
Better corrosion resistance, especially in coastal or industrial areas.
