Installed new customer supplied Bathroom exhaust fan in the first floor bathroom. Customer stated that the bathroom was remodeled a while ago. However, there was an old fan still in its place. There was multiple wires near Junction inside of the fan so we need to remove all the wires inside a junction box. We then install the new fan and ran new ductwork out to A new gooseneck vent out that we installed. We then installed a new switch leg from the new exhaust fan down to a new customer supplied stack switch. Customer now can control the vanity light and the exhaust fan separately.
