Copper Line Set top quality: Not All Copper Is produced equivalent
The term “copper line established” sounds easy, but here’s the catch: copper purity and manufacturing criteria change wildly. low cost imports generally use recycled copper with impurities that weaken the tubing and make it vulnerable to pinhole leaks.
Our copper is ASTM B280 compliant, this means it’s built to the very best HVAC market conventional for seamless copper tube. That translates into:
-
greater burst pressure tolerance (essential for modern higher-pressure refrigerants like R-410A and R-32).
-
improved corrosion resistance, specifically in coastal or industrial areas.

Q2: is usually a pre-insulated line set definitely worth the extra money?
A: Definitely. Pre-insulated sets conserve set up time, stop thermal losses, and secure towards condensation that can cause mould or corrosion issues.
