because there would be a lot more DIY'RS installing them improperly
Been installing more and more Mini Splits lately. Got me thinking today, why don't more or all of the traditional air conditioners use flare nuts on the line sets? Anyone else ever wondered this? Or know? It might even save a lot of air conditioners & especially TXV's that r installed w/ out nitro flo. Of course the manufacturers would need to start putting a filter drier inside all the units.
