Copper Line established top quality: Not All Copper Is made equivalent
The time period “copper line set” Appears easy, but here’s the catch: copper purity and production benchmarks differ wildly. affordable imports usually use recycled copper with impurities that weaken the tubing and enable it to be at risk of pinhole leaks.
Our copper is ASTM B280 compliant, indicating it’s designed to the very best HVAC sector normal for seamless copper tube. That translates into:
-
greater burst tension tolerance (important for contemporary higher-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, particularly in coastal or industrial regions.

Q2: is usually a pre-insulated line set definitely worth the extra money?
A: Totally. Pre-insulated sets help you save set up time, prevent thermal losses, and shield versus condensation that can result in mildew or corrosion concerns.
Q3: How long really should a top quality copper line set last?
A: With good set up and no refrigerant contamination, a premium copper line set can past provided that your HVAC process—normally fifteen to twenty years.
