AC Line Set Installation: where by Most Work opportunities Go Wrong
setting up an AC line established isn’t just “join it and go.” There’s a precise course of action that separates a sloppy hookup from the extensive-Long lasting installation.
widespread shortcuts you’ll see from small-Price tag installers involve:
-
Using leftover tubing from A further position (already contaminated with humidity or particles).
-
Failing to correctly flare or braze connections.
-
Skipping nitrogen purging in the course of brazing (which generates carbon buildup within).
-
Using small-grade insulation that cracks in UV light inside a 12 months.

Copper Line Set high quality: Not All Copper Is Created Equal
The term “copper line set” Appears easy, but listed here’s the capture: copper purity and production benchmarks differ wildly. inexpensive imports frequently use recycled copper with impurities that weaken the tubing and help it become liable to pinhole leaks.
Our copper is ASTM B280 compliant, that means it’s made to the very best HVAC field typical for seamless copper tube. That interprets into:
-
better burst strain tolerance (crucial for modern significant-strain refrigerants like R-410A and R-32).
-
much better corrosion resistance, particularly in coastal or industrial spots.
-
Smoother interior surfaces, which hold refrigerant circulation economical and oil return steady.
