I don't recall that you actually spelled outy what it is that you are trying to do here?
You do know that when you braze HVAC copper lines, that you need to flood them with an oxygen and water free gas, right? If you don't, you will get tiny copper-oxide flakes that can plug your metering device later.
So, what are you doing with all your components?
