Copper Line Set top quality: Not All Copper Is made Equal
The expression “copper line established” Seems clear-cut, but listed here’s the catch: copper purity and manufacturing expectations vary wildly. affordable imports often use recycled copper with impurities that weaken the tubing and make it at risk of pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s made to the highest HVAC sector standard for seamless copper tube. That translates into:
-
better burst pressure tolerance (important for modern higher-stress refrigerants like R-410A and R-32).
-
improved corrosion resistance, specifically in coastal or industrial areas.
