While redoing my plumbing in my master bathroom I opened up the flooring to discover an HVAC line not connected to anything and air is passing thru it!
It’s located above the garage in a large dead space. Surely this can’t be right. I can’t imagine someone thought it a good idea to heat and cool the dead space, unless it’s an attempt to prevent frozen pipes in winter?
Thoughts? At this point I’m considering to simply add another vent since it’s a pretty good size room.
