Measure and check codes before buying.
- Choose ducted for performance, ductless for convenience.
- Turn off power and use proper tools.
- Follow the manual for height and wiring.
- Test everything after installation.
What to Know Before You Install a Range Hood
Check your local building codes before starting. Most codes require a licensed electrician for hardwiring. Measure the space above your stove. Standard height is 24 to 30 inches for gas, 20 to 24 for electric. Decide between ducted and ductless. Ducted vents outside; ductless recirculates air through filters. Look for a hood with a CFM rating matching your cooking needs. Higher CFM suits heavy cooking. Ensure your ceiling or cabinet can support the hood's weight.
Ducted vs Ductless: Which Venting Setup Works for You
Ducted hoods move smoke and grease outside. They require ductwork to the exterior. Ductless hoods use charcoal filters to clean air and recirculate it. If you cannot run ductwork, choose ductless. Ducted systems are more effective at removing heat and odors. Ductless filters need replacement every few months. Consider your kitchen layout and budget. Some hoods convert from ducted to ductless with a kit. Check the hood's specifications for compatibility.
Tools and Materials You Need for Installation
Gather a drill, screwdriver, level, tape measure, and stud finder. You will need screws, anchors, and possibly a jigsaw for cutting duct holes. For ducted installs, have duct pipe, elbows, and foil tape. For ductless, you need a charcoal filter kit. Wear safety glasses and gloves. Turn off power at the circuit breaker before wiring. Have a voltage tester to confirm power is off. If ducting through a cabinet, use a hole saw.
Step-by-Step Installation Process for Wall and Under-Cabinet Hoods
Start by turning off power and removing the old hood. Mark the centerline above the stove. Hold the hood in place and mark screw locations. Drill pilot holes and secure the mounting bracket. Lift the hood onto the bracket and tighten screws. For ducted, connect the duct pipe to the hood's exhaust outlet. Seal joints with foil tape. For ductless, install charcoal filters per the manual. Wire the hood to the house circuit using wire nuts. Secure the wiring and attach the cover. Restore power and test the fan and lights.
Common Installation Mistakes and How to Avoid Them
Do not skip checking for studs. Mounting into drywall alone can cause the hood to fall. Avoid undersizing the duct. Use the diameter specified in the manual. Do not use flexible duct for long runs; it restricts airflow. Ensure the damper opens fully. For ductless, do not forget to remove the plastic wrap from filters. Always connect a ground wire. If you feel unsure about electrical work, call a professional. Test for leaks in duct joints with a smoke pencil.
