Copper Line Set good quality: Not All Copper Is Created equivalent
The term “copper line established” Appears uncomplicated, but in this article’s the catch: copper purity and manufacturing requirements fluctuate wildly. low-priced imports usually use recycled copper with impurities that weaken the tubing and enable it to be liable to pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s made to the best HVAC industry standard for seamless copper tube. That translates into:
-
larger burst force tolerance (critical for modern significant-pressure refrigerants like R-410A and R-32).
-
far better corrosion resistance, specifically in coastal or industrial parts.
-
Smoother interior surfaces, which retain refrigerant move successful and oil return regular.
