AC Line Set Installation: where by Most Work opportunities Go Completely wrong
setting up an AC line set isn’t just “connect it and go.” There’s a precise method that separates a sloppy hookup from a lengthy-Long lasting set up.
typical shortcuts you’ll see from reduced-Expense installers incorporate:
-
making use of leftover tubing from Yet another job (by now contaminated with humidity or debris).

Copper Line Set excellent: Not All Copper Is made equivalent
The time period “copper line set” sounds simple, but in this article’s the catch: copper purity and production requirements change wildly. affordable imports generally use recycled copper with impurities that weaken the tubing and make it liable to pinhole leaks.
Our copper is ASTM B280 compliant, meaning it’s made to the highest HVAC industry common for seamless copper tube. That interprets into:
-
larger burst strain tolerance (critical for modern substantial-force refrigerants like R-410A and R-32).
-
far better corrosion resistance, particularly in coastal or industrial locations.
-
Smoother interior surfaces, which hold refrigerant flow effective and oil return steady.

specific length selections in order to avoid unnecessary joints and lower leak points.
