Installing a kitchen hood under your existing cabinets is one of the most effective ways to improve air quality and reduce lingering cooking odors without undertaking a major renovation. This process requires careful measurement and precise cutting to ensure the unit sits flush against the underside of the cabinetry, creating a seamless look. When done correctly, the hood pulls smoke and grease directly from the source, protecting your walls and cabinets from damage.
Planning Your Under-Cabinet Hood Installation
Before you touch a drill, it is essential to evaluate your current kitchen layout to determine the best location for the hood. You must identify the position of the cabinets above your stove and ensure there is sufficient vertical space between the cooking surface and the bottom of the cabinets. This planning phase is critical for preventing fumes from rising past the capture zone of the unit.
Measuring for Ductwork and Power
Measure the distance from the wall to the edge of your cabinets to establish the width of the hood you need. You also need to decide if you will vent the air outside through your attic or duct it through the wall. If you lack exterior wall access, you will need to opt for a ductless model with an internal carbon filter, though this option is less effective at removing grease particles.

Tools and Materials Required
Gathering the right tools ensures a smoother installation and prevents delays caused by a trip to the hardware store. You will need standard items like a screwdriver and drill, but specific tools like a jigsaw or reciprocating saw are necessary for cutting holes in existing cabinets. Additionally, ensure you have cable ties and duct tape to secure the ventilation path.

Safety Gear
Protect yourself during the cutting process by wearing safety goggles to prevent wood chips from falling into your eyes. You should also use a dust mask when sanding the edges of the cutout and gloves to handle the metal ducting safely. Proper ventilation is necessary even if you are working in an open space.
Step-by-Step Cutting and Mounting
Begin by disconnecting power to the area where you will be working for safety. Locate the studs within the wall or cabinets where the mounting bracket will attach, and mark the spots for your drill holes. Carefully follow the manufacturer's template that came with the hood to outline the exact cutout dimensions on the bottom of the cabinet.

Making the Cut
Drill a pilot hole at one corner of the outlined rectangle to insert your jigsaw blade. Slowly cut along the lines, supporting the weight of the cabinet section to prevent splintering. Once the hole is cut, smooth the edges with sandpaper before attaching the hood rails to the underside of the cabinet using wood screws.
Connecting the Ventilation System
With the hood physically attached, you must now address the ductwork running to the exterior of your home. Use a flexible aluminum duct to connect the outlet on the back of the hood to the wall or roof vent. It is vital to minimize the length and bends in this ductwork to maintain strong suction power that efficiently removes steam.
Secure all connections with foil tape to prevent grease buildup and air leaks, which can reduce the system's efficiency. Finally, restore the power and test the fan speeds to ensure the motor operates quietly and effectively pulls air through the filter. With the installation complete, you can enjoy a kitchen that remains free of smoke and greasy residue.
