Freon lines between floor and ceiling?
I have about eight feet of lines to run between floor and ceiling. I wanted to pull these lines through 3" pvc to avoid possible future damage to the ceiling. There are two 90 degree turns for which I am using two 45's to make it easier. Is it necessary to contain these in pvc (even though I have lubricant it seems that it might be very difficult to accomplish). Should I give up on the idea and just run the though the space making sure they're wrapped well with insulation? Also does a professional have "fittings" to make the turns with out difficulty?
