"There was unable to install recessed lighting in the home due to a metal plate being built into the ceiling. Instead, provider installed a ceiling fan apparatus. It's not centered in the room, so I will not use it. Not sure that such service was comparative to the cost of the recess lighting. All in all, the guys were professional and timely. They did not,however, repair the holes drilled in the ceiling.
