-
making use of leftover tubing from A different job (now contaminated with dampness or debris).
-
Failing to correctly flare or braze connections.
-

Copper Line Set high-quality: Not All Copper Is developed equivalent
The expression “copper line set” sounds simple, but below’s the capture: copper purity and producing expectations change wildly. affordable imports generally use recycled copper with impurities that weaken the tubing and allow it to be vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, which means it’s created to the highest HVAC market typical for seamless copper tube. That interprets into:
-
better burst force tolerance (essential for contemporary large-strain refrigerants like R-410A and R-32).
-
Better corrosion resistance, specifically in coastal or industrial locations.
-
Smoother inside surfaces, which continue to keep refrigerant movement economical and oil return consistent.
