Ductless Installation P2 - Flaring, Charging and More
About this episode
Jesse and I talk about MORE best practices for installing ductless systems.
Both lines should be insulated on a ductless system because they have electric expansion valves in the outdoor unit. Insulating flares is also a critical task. When it comes to flare fittings, overconfidence is a tech's biggest enemy. Techs often undervalue the process of reaming copper or overdo it. Bubble-testing the flare joints is always a best practice to evaluate the integrity of your flares and check for leaks. Do not braze copper on ductless systems!
Ductless evacuations require deep vacuums. Removing cores and valving off are best practices for evacuation; the goal is to reduce the risk of contamination, just like normal split systems.
