New liquid line connected to new a-coil in new air=handler.Line never even connected to new condensing unit.A co-worker installed the new inside unit and liquid line 1 week ago and sealed it/charged it with nitrogen.This is on second floor and line ends in basement.Today I cut the end off to finish the line to outside and oil starts dripping out the end.A lot of it.This is new inside system & a-coil and neither ever hooked up to a condensing unit.Anyone ever ran it to this?
