Upgrade Your Range Hood: A Step-by-Step Guide on How to Convert Ductless to Ducted

Are you tired of your kitchen smelling like last night’s dinner long after the dishes are done? Is your ductless range hood struggling to keep up with your cooking adventures? You’re not alone! Many homeowners find themselves wishing they had opted for a ducted range hood instead of a ductless one.
But don’t despair! Converting a ductless range hood to a ducted system is a feasible DIY project that can significantly improve your kitchen’s air quality and overall cooking experience. This guide will walk you through the process, from assessing your needs to installing the new system.

Why Convert to a Ducted Range Hood?

Ductless range hoods, also known as recirculating hoods, filter and reintroduce the air back into your kitchen. While convenient, they aren’t as effective as ducted hoods at removing cooking odors, grease, and smoke.
Here’s why converting to a ducted range hood is a worthwhile endeavor:

• Superior Odor Removal: Ducted hoods vent cooking fumes and odors outside, preventing them from lingering in your kitchen.
• Cleaner Air: By removing grease and smoke, ducted hoods contribute to a healthier indoor environment, especially for those with respiratory sensitivities.
• Increased Efficiency: Ducted hoods are generally more powerful than ductless models, allowing them to effectively capture and vent large amounts of cooking fumes.
• Reduced Cleaning: With the majority of grease and smoke being vented outside, ducted hoods require less frequent cleaning compared to their ductless counterparts.

Assessing Your Needs

Before embarking on your conversion project, consider these key factors:

• Existing Ductwork: Do you have existing ductwork that can be utilized? If not, you’ll need to install new ductwork, which can be a more complex and expensive undertaking.
• Hood Size and Power: The size and power of your existing hood will determine whether it can be converted or if a new hood is necessary.
• Ventilation Location: Where will the ductwork exit your home? Consider factors like roof access, nearby trees, and neighborhood aesthetics.

Choosing the Right Ducted Hood

Once you’ve assessed your needs, it’s time to choose a ducted range hood that meets your requirements. Here are some essential considerations:

• Size: Ensure the hood is wide enough to cover your cooktop and has sufficient power to effectively vent the space.
• CFM Rating: The CFM (Cubic Feet per Minute) rating indicates the hood’s airflow capacity. Higher CFM ratings are typically better for larger kitchens and heavy cooking.
• Noise Level: Opt for a hood with a low noise level, especially if your kitchen is open to other living areas.
• Features: Consider features like blower speed controls, lighting, and filter types to suit your preferences.

Installing the Ductwork

Installing ductwork is the most challenging aspect of converting a ductless range hood to a ducted system. Here’s a general overview of the process:

• Route the Ductwork: Plan the path of the ductwork from your hood to the exterior vent. Consider using flexible ductwork for easier installation and maneuvering around obstacles.
• Secure the Ductwork: Use duct tape or clamps to securely connect the ductwork sections.
• Insulate the Ductwork: Insulating the ductwork helps prevent condensation and minimizes noise.
• Install the Exterior Vent: Choose a vent that is compatible with your ductwork and meets local building codes.

Connecting the Hood to the Ductwork

Once the ductwork is installed, you’ll need to connect your range hood to it.

• Check Compatibility: Ensure your existing hood is compatible with ducted systems. Some models may require modifications or replacements.
• Connect the Ductwork: Securely attach the ductwork to the hood’s outlet.
• Seal the Connections: Use duct tape or sealant to create airtight connections, preventing leaks and ensuring efficient ventilation.

Testing and Final Touches

After connecting the ductwork and hood, it’s time to test the new system:

• Turn on the Hood: Run the hood at different speed settings to check for proper airflow and noise levels.
• Inspect for Leaks: Look for any leaks or gaps in the ductwork and seal them as needed.
• Adjust the Hood: Fine-tune the hood’s settings and position to achieve optimal performance.

Embracing the Fresh Air

Converting your ductless range hood to a ducted system can transform your kitchen into a more pleasant and healthier space. By following these steps, you’ll enjoy the benefits of superior odor removal, cleaner air, and a more efficient cooking environment.

Questions We Hear a Lot

Q: Can I convert any ductless range hood to a ducted system?
A: While many ductless hoods can be converted, it’s crucial to check for compatibility. Some models may not have the necessary components or may require modifications.
Q: How much does it cost to convert a ductless range hood to a ducted system?
A: The cost varies depending on factors such as the length and complexity of the ductwork, the type of hood, and labor costs. Generally, expect to spend anywhere from a few hundred dollars to a few thousand dollars.
Q: Can I install the ductwork myself?
A: While it’s possible to install ductwork yourself, it’s a challenging project that requires knowledge of building codes and safety precautions. If you’re not comfortable with DIY projects, it’s best to hire a professional.
Q: What are some tips for maintaining a ducted range hood?
A: Regularly clean the hood’s filters, inspect the ductwork for leaks or blockages, and ensure the exterior vent is clear of obstructions.
