A bathroom vent fan not only removes moisture and unwanted odors but also cuts down on mold problems, eliminates window and door warping, and helps defog the mirror. With time, an old fan wears out; it is worth your while to replace it with a quieter, higher-capacity model.
Choose the lowest sone rating (0.5 is nearly silent, 4.0 is about as loud as a TV) you can afford. Before beginning, shut off the power at the electrical panel.
The connections on this job are simple; however, working overhead to remove the old unit is no fun. Be sure to wear workwear gloves, long sleeves, a cap, and respiratory and eye protection - falling insulation is inevitable.
What You’ll Need: Phillips screwdriver, pry bar, drill/driver and bits, mini hacksaw, utility knife, cutting/stripping pliers, new vent fan, cable clamp, duct tape, wire nuts
