Installing a range hood involves proper preparation of the installation site along with preparing ductwork and electrical wires. It can be a DIY project, but Karl Ulatowski, the owner and general contractor of Hearthstone Home Remodeling, cautions homeowners that it can also be a frustrating project. It’s a job that is best left to a professional. The specific process will vary depending on your home’s layout and the type of range hood you choose. Generally, first, you must ensure that you have the proper ductwork for the exhaust fan. The duct should be the most direct route out of the house, either through an exterior wall or the roof. After the ductwork is in place, you’ll need to verify that you have access to the electrical wiring. Then you can proceed with the installation of the range hood according to mounting type. Under-cabinet range hoods will mount to cabinets over the stove, while wall-mounted range hoods will attach to the wall. Before fastening the range hood in place, connect the wiring in the hood’s electrical box and ensure that the duct connector is secure. Then, tighten the screws to fully secure the range hood.
