An old kitchen range exhaust system may no longer perform efficiently, leading to inadequate ventilation, grease buildup, and unpleasant odors. Upgrading or maintaining your range hood ensures better air quality, a cleaner kitchen, and compliance with modern safety and building standards. Here’s how to assess and address an aging exhaust system.
Signs Your Kitchen Range Exhaust System Needs an Upgrade
1. Ineffective Ventilation
• Smoke, steam, or cooking odors linger longer than usual.
2. Excessive Noise
• The system produces loud or unusual sounds, indicating wear or outdated technology.
3. Frequent Maintenance Issues
• Persistent problems like clogged filters, weak airflow, or motor failure.
4. Grease Accumulation
• Visible grease buildup inside the range hood or on kitchen surfaces due to poor extraction.
5. Outdated Design
• The system lacks modern features like energy efficiency, quieter operation, or effective lighting.
6. Non-Compliance with Current Codes
• The system may not meet modern building or ventilation standards, especially in older homes.
Options for Upgrading an Old Kitchen Range Exhaust System
1. Replace the Range Hood
• Choose a new model that fits your kitchen’s design and ventilation needs:
• Under-Cabinet Range Hoods: Compact and fits under cabinets.
• Wall-Mounted Range Hoods: For kitchens with open walls above the range.
• Island Range Hoods: Ideal for ranges on kitchen islands.
• Downdraft Ventilation Systems: Pull air downward and vent through the floor.
2. Upgrade to a Ducted System
• If the current system is ductless, consider switching to a ducted range hood for better airflow and external venting.
• Ensure proper routing of ductwork to the exterior of your home.
3. Install Modern Features
• Energy-Efficient Motors: Reduce power consumption while maintaining strong airflow.
• LED Lighting: Brighten your cooking area with long-lasting, energy-efficient lighting.
• Touch Controls and Timers: Offer convenient operation and better control.
• Automatic Sensors: Adjust ventilation based on cooking activity or humidity levels.
4. Increase CFM Capacity
• Choose a model with a higher cubic feet per minute (CFM) rating to handle heavy cooking loads, especially for gas ranges.
• Typical recommendations:
• 100 CFM per 10,000 BTU for gas ranges.
• 150 CFM minimum for electric ranges.
Steps to Replace or Upgrade Your Exhaust System
1. Measure the Existing Space
• Measure the width, height, and depth of the existing range hood to ensure a proper fit.
• Standard sizes are typically 30 or 36 inches wide.
2. Select a New Model
• Choose a range hood based on your kitchen layout, cooking habits, and ventilation requirements.
3. Install or Upgrade Ductwork
• For ducted systems, ensure the ductwork is properly routed to the exterior with minimal bends to maintain efficient airflow.
• Replace old or damaged ducting with rigid metal ducts for durability.
4. Install the New Range Hood
• Follow the manufacturer’s instructions for installation or hire a professional if the setup involves electrical work or significant modifications.
5. Test the System
• Turn on the range hood and test its airflow, lighting, and controls to ensure everything functions correctly.
Maintenance Tips for Prolonging System Life
1. Clean Filters Regularly
• Wash reusable metal filters or replace disposable ones every 1–3 months.
• Grease filters help maintain airflow and reduce fire hazards.
2. Inspect Ductwork
• Check for blockages or damage in the ducting and clean as needed.
3. Clean the Interior and Exterior
• Wipe down the range hood’s surfaces to remove grease and dust.
4. Perform Annual Maintenance
• Inspect the motor, fan, and electrical components to ensure proper operation.
When to Call a Professional
• Electrical Upgrades: Hire a licensed electrician if rewiring or installing a new outlet is required.
• Ductwork Installation: Consult an HVAC technician for complex duct installations or rerouting.
• Code Compliance: A professional can ensure the new system meets local building codes and safety standards.
Benefits of Upgrading an Old Kitchen Range Exhaust System
• Improved Air Quality: Efficient ventilation removes smoke, odors, and grease more effectively.
• Energy Efficiency: Modern range hoods use less power and operate more quietly.
• Enhanced Kitchen Appearance: Sleek, updated designs add style to your cooking space.
• Compliance with Codes: A new system ensures safety and meets modern ventilation requirements.
Upgrading your kitchen range exhaust system enhances the functionality, safety, and aesthetics of your kitchen. Whether you choose a simple replacement or a full system upgrade, addressing an old exhaust system is a worthwhile investment for a cleaner, healthier home.
