Replacing a kitchen range hood is a relatively straightforward DIY project that can dramatically improve both the function and look of your kitchen. Whether your current hood is loud, outdated, or not venting properly, upgrading it typically costs between $200 and $1,000 for the unit, plus $100 to $400 if you hire an electrician for installation. All in, most homeowners spend $300 to $1,400 depending on the model and complexity of the wiring.
You’ll need to choose between a ducted system that vents air outside and a ductless model that recirculates air through filters. Ducted systems work better for odor and moisture control, but they’re more involved to install — especially if your kitchen doesn’t already have exterior venting in place.
In this guide, we’ll walk you through every step of the range hood replacement process, including safety tips, wiring basics, and how to tell whether it’s time to call in a pro. If you’re upgrading multiple appliances, it may also be worth looking into extended protection — check out our Kenmore Appliance Warranty guide to learn how to safeguard your investment.
How Do You Replace a Range Hood?
Swapping out an old range hood for a new one is usually a manageable DIY job — especially if you’re replacing it with the same type and size. Here’s how to do it safely and efficiently.
- Turn off the power at the breaker.
Never trust a wall switch alone. Shut off the circuit at your main panel to cut power to the range hood. - Remove the old hood.
Take out the filter and cover plate to access the wiring and mounting screws. Disconnect the wires (note which ones connect where), then unscrew the unit from the wall or cabinet. Have someone support the hood while you detach it. - Check your venting setup.
Decide if your new range hood will vent outside or recirculate air. If switching from ductless to ducted, or vice versa, additional installation steps may be required — especially for venting through a wall or ceiling. - Prep the new hood.
Follow the manufacturer’s instructions to configure the hood for ducted or ductless use. Attach any required brackets or adapters before installing. - Position the new hood.
Snake the power wires through the hole in the hood. Lift the unit into place, align it with the cabinet or wall, and secure it with mounting screws. - Reconnect the wiring.
Match up the wires — typically black to black (hot), white to white (neutral), and green or bare copper to the ground screw. Use wire nuts and electrical tape to secure the connections. - Install filters, covers, and bulbs.
Snap in the grease filter and reattach the cover plate. Install any included light bulbs, ideally LED for energy efficiency. - Restore power and test.
Flip the breaker back on and test the fan and lights. If the unit doesn’t power on, double-check your wiring connections and breaker.
When To Call a Pro
Replacing a range hood is a doable project for confident DIYers, but don’t push your limits. Call in a licensed electrician or handyman if:
- You’re installing a range hood where there wasn’t one before.
- The new hood requires a dedicated circuit or upgraded wiring.
- You’re switching from ductless to ducted and need new venting cut through a wall or ceiling.
- You’re not comfortable handling electrical connections — safety comes first.
In these cases, a pro can make sure everything’s up to code and working safely. Expect to pay around $100–$400 for professional installation, depending on job complexity.
Range Hood Replacement Cost Breakdown
| Item | Typical Cost |
|---|---|
| Basic ductless range hood | $200–$400 |
| Mid-range ducted model | $400–$700 |
| High-end or custom hood | $700–$1,200+ |
| Professional installation | $100–$400 |
| Total (DIY install) | $200–$1,200 |
| Total (Pro install) | $300–$1,400+ |
Tip: If you’re upgrading other kitchen appliances at the same time, ask your installer about bundle discounts — some contractors offer package deals for multi-appliance installs.
Frequently Asked Questions
Do I need an electrician to replace a range hood?
If you’re doing a simple swap with a similar model and you’re comfortable working with household wiring, it’s usually safe to DIY — just be sure to shut off power at the breaker before disconnecting or connecting wires.
However, if you’re installing a range hood for the first time or upgrading to a more powerful unit that requires new wiring or a dedicated circuit, hire a licensed electrician. Electrical work beyond basic connections should never be improvised.
What’s the difference between ducted and ductless range hoods?
Ducted range hoods vent cooking fumes, grease, and moisture to the outside through a system of ducts. They’re more effective, especially for high-heat or heavy-use cooking, but require exterior venting.
Ductless models filter the air using charcoal filters and recirculate it back into the kitchen. These are easier to install and work well in apartments or homes where ducting isn’t feasible — just know they won’t remove humidity or odors as efficiently.
How do I know if my range hood needs to be replaced?
If your current range hood isn’t pulling air effectively, is excessively loud, has a burnt-out motor, or has visible damage or corrosion, it’s likely time for a replacement. Another telltale sign: the lights or fan don’t work even after replacing bulbs or checking the switch.
Modern hoods also offer better performance and energy efficiency, so upgrading can be worth it even before total failure.
Can I install a larger range hood than the old one?
Yes — and in fact, it’s often a smart move. Ideally, your range hood should be at least as wide as your cooktop (typically 30 or 36 inches), and a few extra inches of width can improve ventilation. Just make sure your cabinet or wall space can accommodate it, and be ready to modify mounting points or vent placement if switching to a larger unit.
How often should range hood filters be replaced or cleaned?
If you have a ductless hood with charcoal filters, plan to replace the filters every 3 to 6 months, depending on how often you cook. Metal grease filters on both ducted and ductless hoods should be removed and cleaned with soap and hot water every month or two. Letting grease build up reduces airflow and can become a fire hazard.
