Installing a new range hood can dramatically improve the air quality and ventilation in your kitchen. Range hoods efficiently remove smoke, grease, odors, moisture, and other pollutants from the air while you cook. They also provide bright task lighting over your stove or cooktop.
Replacing an old, outdated range hood with a powerful new one can make a huge difference in your cooking experience. While range hood installation may seem intimidating, it can be a surprisingly straightforward DIY project for many homeowners. Here is a step-by-step guide on how to install a range hood in your kitchen.
Choose the Right Range Hood for Your Kitchen
When selecting a new range hood, there are several factors to consider:
Type of Range Hood
The two main types are:
- Ducted – Ducted range hoods are installed with a duct that vents outdoors. This is the most effective type for air filtration. However, installing the ductwork can be challenging if there are no existing ventilation shafts.
- Ductless – Ductless range hoods recirculate the air through filters without venting outside. They are easier to install but won’t remove pollutants from your home.
Size and Dimensions
Pick a range hood that is at least as wide as your cooktop or stove. It should overhang the cooking surface by at least 3 inches on each side. Consider the ceiling height and your personal needs when choosing the width and depth.
CFM and Noise Level
CFM stands for “cubic feet per minute” and indicates the airflow. A higher CFM means more powerful ventilation. For a home kitchen, look for around 300 CFM or more. Also check the noise level ratings. Models with 6.0 sones or less are considered quiet.
Ventilation Power
The ducted or ductless ventilation system must be robust enough for the CFM rating on the range hood. Carefully match the CFM and ducting.
Features
Consider lighting brightness, filter types, exhaust vents, and convenience features. Brushed stainless steel hoods are popular for a modern look.
Prepare the Installation Space
Once you have selected the ideal range hood, the next step is preparing the installation area above your stove.
Measure Carefully
Measure the distance between the cooktop and the bottom of the cabinets. Be extremely precise. This measurement will determine the type of mounting.
Inspect Electrical and Ventilation
- For a ducted hood, check for existing ductwork or the ability to install new ducts. Measure duct dimensions.
- Confirm sufficient electrical power supply for the range hood.
- Mind adjacent cabinets, microwave installations, etc. that may interfere.
Install Routing for Electrical
- Turn off power supply before beginning electrical work.
- Install new wire routing if necessary to reach the range hood location.
Install the Mounting Bracket
Most range hoods include a sturdy metal mounting bracket that affixes directly to the wall or cabinets.
Determine the Height
Double check your measurements and determine the exact desired height for the bottom of the range hood. Mark this clearly on the wall.
Fasten the Bracket
Hold the mounting bracket in position, leveled and centered over the stove. Use a level tool to ensure accuracy. Fasten securely into wall studs or upper cabinet bottom with appropriate screws.
Test the Fit
Temporarily fit the range hood itself onto the bracket. Verify that it rests at the perfect height and fits snugly against the wall or cabinets. Remove hood.
Connect the Vents and Electrical
With the mounting bracket installed, the next stage is connecting ventilation ducts and electrical power.
Install Insulated Ducting
For ducted range hoods, attach rigid or semi-rigid insulated ducting from the hood location through cabinets and outwards. Maintain as straight and smooth of a path as possible. Connect exhaust vent outdoors.
Wire the Electrical Supply
Connect household wiring according to the manufacturer’s instructions. Typically, this involves attaching the wires to the range hood and then feeding the cord through to connect to an outlet.
Test Fan Speeds
Briefly switch on the power and test ventilation speeds using the range hood controls. Then turn off power again.
Mount the Range Hood Itself
Now you’re ready for the satisfying final step – installing the range hood itself.
Attach Filters and Bulbs
Insert any filters, lights bulbs, chimney flue pieces or other accessories into the range hood body. Follow manufacturer directions.
Mount the Hood
Lift the range hood into position on the mounting bracket. Attach fully using the manufacturer’s mounting hardware. Insert any screws, bolts or clips to affix it firmly.
Reconnect Power and Ducting
Reconnect the ducting and electrical power. Seal up any gaps around the ducting.
Test All Functions
Turn on the unit and test all lighting, fan speeds and other functions. Ensure grease filters and vents are operating correctly.
Congratulations! Enjoy your greater air quality and ventilation with your newly installed range hood!
FAQs About Installing Range Hoods
Many homeowners have additional questions when learning how to install a new range hood. Here are answers to some of the most frequently asked questions.
Is installing a range hood difficult?
Installing a typical ducted or ductless range hood is a moderately difficult DIY project. With proper preparation and patience, most homeowners can install a hood on their own. The most challenging aspects are usually running new ducting and electrical.
What tools do I need to install a range hood?
Common tools include:
- Tape measure
- Screwdriver
- Drill
- Drywall saw
- Level
- Utility knife
- Wire strippers
- Clamps
You may also need a jigsaw or rotary tool for cutting holes through cabinets for ducting. Always use appropriate safety gear like gloves and eye protection.
Where should a range hood be installed?
Ideally, the bottom of the range hood should be 24 – 30 inches above the cooking surface. Measure the recommended height for your specific model. The hood should also be centered directly over the stove or cooktop below.
Do range hoods need to vent outside?
It is highly recommended to install ducted range hoods that vent outdoors whenever possible. This is the only way to fully remove contaminants rather than just recirculating the same air. Ductless models are usually only suitable for occasional, light cooking.
How loud are range hoods?
Look for range hoods with noise levels around 6.0 sones or lower. Models rated for higher CFM airflows tend to be noisier. Use sound dampening insulation around ducting to reduce vibration noises.
What gauge wiring do range hoods need?
In the United States, range hoods usually require a 120-volt circuit. Typical wire gauges are 14 or 12 AWG. Always verify the recommended wire gauge specified in the manufacturer’s installation instructions.
Do I need to hire an electrician to install a range hood?
If your kitchen already has the necessary electrical supply, you likely do not need to hire an electrician. Use extreme caution when working with electrical wiring yourself. If running new wiring, it may be advisable to hire an electrician depending on your experience level.
How long does range hood installation take?
Expect installation to take between 2 – 5 hours for most do-it-yourselfers. This varies based on the complexity of your house’s electrical and ductwork. Hiring a professional usually cuts installation time significantly.
What height should a range hood be above the cooktop?
The standard recommendation is to install a range hood 24 to 30 inches above the cooking surface. However, always defer to the manufacturer’s instructions for your specific appliance. Some hoods are designed to be mounted higher or lower.
Can I install a range hood myself?
Yes, installing a range hood is a DIY friendly project for many homeowners. With proper preparation and safety precautions, you can likely handle the installation – especially if your house already has the necessary ducting and electrical. Still, don’t hesitate to call in a professional if you feel unsure.
Conclusion
Installing a modern, powerful range hood brings major air quality and ventilation improvements to any kitchen. While installing a range hood requires careful planning and preparation, it can be an approachable DIY project for many homeowners. Follow the steps outlined above to choose the right hood, prepare the space, install the mounting bracket, connect ducting and wiring, and finally mount the range hood itself. Then you can enjoy cleaner air and a brighter, more functional cooking space.
