Why Replace Your Kitchen Hood?
There are several compelling reasons to consider replacing your kitchen hood. An old or underperforming hood can leave your kitchen filled with smoke, grease, and odors. Upgrading can offer better ventilation, quieter operation, and a more modern look. Let’s delve into the common motivations:
Performance Issues
- Poor Ventilation: If your current hood doesn’t effectively remove smoke, steam, and cooking odors, it’s a strong indicator for replacement. This is a primary function of an exhaust fan replacement.
- Loud Operation: Older hoods can become noisy. A new unit might offer significantly quieter operation, making your cooking experience more pleasant.
- Ineffective Lighting: The built-in lights might be dim or non-functional, hindering visibility while cooking.
- Grease Buildup: Over time, grease can clog filters and internal components, reducing efficiency and potentially becoming a fire hazard. This ties into cooker hood maintenance and can sometimes lead to cooker hood repair needs that are better addressed by a replacement.
Aesthetic and Functional Upgrades
- Modernizing Your Kitchen: A new kitchen hood can be a focal point, updating the look of your kitchen.
- Increased CFM (Cubic Feet per Minute): If you’ve upgraded your cooktop to a more powerful model, you might need a hood with a higher CFM rating to handle the increased ventilation requirements.
- New Features: Modern hoods offer features like variable fan speeds, delayed shut-off, heat sensors, and Wi-Fi connectivity.
- Switching Hood Types: You might be moving from an under cabinet hood swap to a more stylish wall-mount unit, or from a ducted system to a ductless range hood change. Even a microwave hood removal to a dedicated hood is a common upgrade.
When is Repair Not Enough?
While ventilation hood repair can sometimes fix minor issues, persistent problems, significant rust, or outdated technology often make replacement the more cost-effective and efficient long-term solution. For example, a failing motor in an old unit might be costly to replace, making an exhaust fan replacement a better choice. Similarly, a downdraft vent replacement can be complex, and if the unit is old, a new one might be more reliable.
Choosing Your New Kitchen Hood
Before you start unscrewing anything, selecting the right replacement hood is crucial. Consider these factors:
Type of Hood
- Under-Cabinet Hoods: These are mounted directly beneath your kitchen cabinets. They are often the most budget-friendly and easiest to install, especially if replacing a similar unit. This is ideal for an under cabinet hood swap.
- Wall-Mount Chimney Hoods: These are mounted on the wall above your range and often have a chimney that extends to the ceiling. They offer a modern, professional look and are available in a wide range of styles and power levels. This is perfect for a wall mount hood installation.
- Island Hoods: Designed to hang from the ceiling above a kitchen island cooktop. They are often larger and more decorative.
- Downdraft Hoods: These rise from the cooktop surface or countertop itself. They are great for kitchens with limited overhead space or where an unobstructed view is desired. A downdraft vent replacement involves specific installation considerations.
- Microwave Combination Hoods: These units combine a microwave oven with a ventilation hood. If you’re performing a microwave hood removal to install a dedicated hood, you’ll have more flexibility in your choice.
- Ductless (Recirculating) Hoods: These hoods filter the air and recirculate it back into the kitchen. They are easier to install as they don’t require ductwork, but they are generally less effective at removing airborne grease and odors compared to ducted systems. Changing to a ductless range hood change can simplify installation.
Ventilation Type: Ducted vs. Ductless
- Ducted: The most effective type. It captures smoke, grease, and odors and vents them outside your home through ductwork. This requires an existing vent or the ability to install one.
- Ductless: Filters air through charcoal and mesh filters and returns it to the kitchen. Requires regular filter replacement.
Size and Fit
- Width: The hood should generally be the same width or slightly wider than your cooktop (usually 30-36 inches). Measure your cooktop carefully.
- Depth: Ensure the hood extends far enough out to capture cooking fumes effectively.
- Height: For wall-mount and island hoods, the distance between the cooktop and the hood is critical for optimal performance and safety. Check the manufacturer’s recommendations, usually between 24-36 inches.
CFM Rating
CFM measures how much air the hood can move per minute. A general rule of thumb is to have a CFM rating at least 100 CFM higher than your cooktop’s BTU (British Thermal Unit) rating. However, for powerful gas ranges, you might need 1.5 times the BTU rating in CFM.
Noise Level (Sonos)
Hoods are rated in sones. A lower sone number means a quieter hood. Look for units with sone ratings below 2 or 3 for a more pleasant experience.
Filters
- Mesh Filters: Most common and effective at trapping grease. They are usually dishwasher-safe for easy cleaning, a key aspect of cooker hood maintenance.
- Baffle Filters: More efficient at trapping grease and are also typically dishwasher-safe.
- Charcoal Filters: Used in ductless systems to filter odors. These need to be replaced periodically.
Lighting
Consider the type and brightness of the lighting. LED lights are energy-efficient and long-lasting.

Safety First: Before You Begin
Working with electricity and overhead fixtures requires caution. Prioritize safety throughout the entire process.
1. Turn Off Power!
This is the most critical step. Locate your home’s electrical panel (breaker box) and switch off the breaker that controls the power to your kitchen hood and the surrounding area. It’s good practice to also turn off the main power to the kitchen if you’re unsure which breaker controls the hood. Use your voltage tester to confirm the power is off at the hood’s electrical connection point before touching any wires.
2. Read the Manuals
Both your old hood’s manual (if available) and, more importantly, the installation manual for your new hood are essential. They will provide specific instructions tailored to your new unit.
3. Work with a Partner
Having someone to help support the weight of the hood, hand you tools, and provide an extra pair of eyes can significantly improve safety and ease.
4. Secure Your Workspace
Clear the area around your stovetop and under the hood. Ensure your ladder or step stool is stable and placed on a level surface.
Step-by-Step Guide to Replacing Your Kitchen Hood
This guide covers the general process. Always refer to your new hood’s specific installation manual.
Section 1: Removing the Old Kitchen Hood
This is the first major phase of the under cabinet hood swap, wall mount hood installation, or any other type of replacement.
Step 1.1: Access the Electrical Connection
- Look for an access panel on the old hood. This is often a small cover on the underside or back of the unit.
- Use your screwdriver to remove the screws holding this panel in place.
Step 1.2: Disconnect the Wiring
- Confirm Power is OFF with your voltage tester again!
- You’ll see wires, typically black (hot), white (neutral), and green or bare copper (ground). They will be connected to your home’s wiring using wire nuts.
- Carefully unscrew the wire nuts connecting the hood’s wires to your house wires.
- Gently pull the wires apart.
- Cap the house wires with new wire nuts to ensure they are safely insulated. You can also wrap them with electrical tape for extra security.
Step 1.3: Disconnect Ductwork (If Applicable)
- If your hood is ducted, it will be connected to ductwork via a collar or flange.
- This connection is usually secured with a hose clamp or screws.
- Loosen the clamp or remove the screws.
- Gently twist and pull the ductwork away from the hood. If it’s flexible ducting, it might be stuck; a gentle tug or a utility knife to carefully cut away sealant might be needed. Be careful not to damage the existing ductwork if you plan to reuse it.
Step 1.4: Support the Hood
- Most hoods are secured by screws to cabinets or walls. Before removing the last screws, ensure the hood is adequately supported. Have your helper hold it firmly, or place a sturdy box or your arms underneath it.
Step 1.5: Remove Mounting Screws
- Locate the screws that hold the hood in place. These are typically in the front, back, or sides, attaching it to the cabinets above or the wall.
- Carefully remove these screws, holding the hood securely as you do.
Step 1.6: Lower and Remove the Old Hood
- With all screws removed and the electrical and duct connections disconnected, carefully lower the old hood.
- Make sure your helper is ready to take the weight.
- Move the old hood out of the way.
Step 1.7: Clean the Area
- While the old hood is out, it’s the perfect time to clean the area where it was mounted. Remove any grease, dust, or debris. This is part of good cooker hood maintenance.
Section 2: Installing the New Kitchen Hood
Now for the exciting part – range hood installation!
Step 2.1: Prepare the Mounting Area
- Compare the mounting dimensions of your new hood with the old one. If it’s an identical fit, this step might be minimal.
- If there are slight differences, you might need to drill new pilot holes for screws. Use your tape measure and level to mark the correct positions accurately.
- If you need to cut a new opening for ductwork or a different type of hood, do so now. A drywall saw or reciprocating saw is useful here. If you’re performing a wall mount hood installation and need to create a vent hole through an exterior wall, this will be more involved.
Step 2.2: Mount the New Hood (or Mounting Bracket)
- Many hoods come with a separate mounting bracket that attaches to the wall or cabinets first. Follow the manufacturer’s instructions for attaching this bracket securely. Use a level to ensure it’s straight.
- If the hood mounts directly, you might need your helper to hold it in place while you secure it.
- Align the hood with the mounting holes.
Step 2.3: Secure the New Hood
- Insert and tighten the mounting screws provided with the new hood. Again, ensure the hood is level and flush against the mounting surface. Don’t overtighten, which could strip the screws or damage the mounting surface.
Step 2.4: Connect the Ductwork (If Applicable)
- If you are using ducted ventilation, align the hood’s exhaust outlet with your existing or newly installed ductwork.
- Attach the ducting using the provided collar or flange.
- Secure it firmly with a hose clamp or screws.
- Use appropriate duct tape to seal any seams, ensuring an airtight connection. This is crucial for efficient ventilation.
Step 2.5: Connect the Electrical Wiring
- Safety Reminder: Double-check that the power is still OFF!
- Identify the wires on your new hood. They should correspond to the house wiring: usually black (hot), white (neutral), and green or bare copper (ground).
- Connect the wires using wire nuts:
- Black hood wire to black house wire.
- White hood wire to white house wire.
- Green or bare copper hood wire to the ground wire from your house (often green or bare copper).
- Tug gently on each connection to ensure it’s secure.
- Tuck the wires neatly into the junction box or designated area on the hood.
- Replace the electrical access panel.
Step 2.6: Install Filters and Accessories
- Install the grease filters according to the manufacturer’s instructions.
- Attach any other included components, such as lighting covers or charcoal filters (for ductless systems).
Step 2.7: Test the Hood
- Once everything is connected and secured, it’s time to test.
- Go back to your electrical panel and turn the breaker ON.
- Turn on the hood’s fan at its lowest setting. Check if the fan operates smoothly and if the lights turn on.
- Listen for any unusual noises.
- Increase the fan speed and check its performance.
- If you have a ducted system, check for airflow at the exterior vent if possible.
Step 2.8: Final Touches and Cleanup
- If there are any gaps between the hood and the wall or cabinets, you might want to seal them with paintable caulk for a clean finish.
- Clean up any dust or debris from the installation process.
- Dispose of your old hood properly.
