Copper Line Set top quality: Not All Copper Is designed Equal
The term “copper line established” sounds easy, but here’s the capture: copper purity and production requirements vary wildly. inexpensive imports frequently use recycled copper with impurities that weaken the tubing and make it at risk of pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s made to the highest HVAC sector conventional for seamless copper tube. That translates into:
-
Higher burst stress tolerance (critical for modern superior-stress refrigerants like R-410A and R-32).
-
greater corrosion resistance, specifically in coastal or industrial places.
-
Smoother interior surfaces, which hold refrigerant flow productive and oil return constant.

-
specific size possibilities to prevent pointless joints and lower leak points.
That’s why our prospects see less callbacks, lengthier procedure existence, and lower utility payments when compared with individuals that accept “adequate.”

Q2: is really a pre-insulated line established worth the extra cash?
A: Unquestionably. Pre-insulated sets help you save set up time, avoid thermal losses, and shield versus condensation that can lead to mould or corrosion problems.
