I didn't...I ran them inside the walls like he should have, and said he would.. It took us a lot longer to do it right, but the client was willing to pay for it done the right way. It took us 4 2" holes in a closet, and one in the basment to get the wires to all locations. Once we patched and painted them you couldn't even notice we were there. The client is very pleased and we have been continuing to work there for the last week installing a Niles ZR4630 for 5 rooms.
