What is the best way to burry a line set? I am doing some planning for my rebuild and because of the size of the new HE condensers it looks like one will need to be situated away from the house if the inside position for the furnace need to go on that side of the house. We may need to create an island garden for it. Maybe 15' from the house.
Other than making sure no one hits the line set with a shovel after it is buried ............ what are the problems with doing this?
