Had a nightmare installing a ceiling fan this weekend. TL;DR: Took 5 hours to install a basic ceiling fan in the master bedroom.
Granted it was my first time installing a fan, but that wasn't a problem. The problem is removing one of those boob lights from the master bedroom to find that it was covering a 12" square hole in the ceiling, so made a last minute trip to Lowe's for a medallion right before they closed. The light had been mounted to two 2x4 blocks screwed together into the joist, and of course the freaking 4" screws holding the blocks are stripped. Finally get those out, and there's a recessed incandescent lighting box in the opening that has to be removed to get the wiring through, so did that with all sorts of grey insulation pouring out. Once I could actually get started hanging the fan it took 50 minutes. Total time invested: 5 hours. Horseshit. I love finding surprises from lazy owners.
On the plus side, no more box fan in the bedroom, fan is silent, and cam pre-wired for a remote with 6 speeds, dimming lights, home security feature (turns on randomly for 5-20 minutes), and a fan timer.
