Ceiling Fan - Install
$160
John was on time and texted me when he was on his way with an ETA. He was polite and efficient and got the job done in less time than anticipated. He installed a blade fan with a light.I would highly recommend using him as an electrician and have already referred him to a friend in my neighborhood.
