Your Complete Guide to Range Hood Replacement: When, Why, and How

Is your range hood making strange noises, failing to clear smoke effectively, or simply looking outdated? Range hood replacement might be exactly what your kitchen needs. Whether you're dealing with a broken unit or planning a kitchen upgrade, this comprehensive guide will walk you through everything you need to know about replacing your range hood.

3 Signs It's Time to Replace Your Range Hood

Performance Issues

• Weak suction that doesn't clear smoke or steam effectively
• Excessive noise during operation (grinding, rattling, or squealing sounds)
• Lights that flicker or don't work at all
• Controls that are unresponsive or intermittent
• Visible grease buildup that won't clean off despite thorough maintenance

Age and Efficiency

• The hood is over 10-15 years old
• Replacement parts are no longer available
• The unit doesn't meet current ventilation needs for your cooking style

Aesthetic Reasons

• Outdated design that doesn't match your kitchen renovation
• Visible rust, dents, or permanent discoloration
• Size doesn't properly fit your current cooktop setup
• Upgrade to modern features like variable speed controls or LED lighting

Choosing the Right Replacement

CFM Requirements

Calculate your ventilation needs based on:

• Gas cooktops: 100 CFM per 10,000 BTU
• Electric cooktops: 100 CFM per 10 inches of width
• Heavy cooking: Add 25-50% to base requirements
• Island installations: Increase CFM by 25% due to cross-drafts

Noise Levels

Look for hoods with sound ratings under 3 sones for quiet operation. Modern range hoods often feature:

• Variable speed controls for different noise levels
• Insulated motor housings
• Aerodynamic fan blade designs

Filter Types

• Baffle filters: Best for heavy cooking, dishwasher-safe
• Mesh filters: Good for moderate cooking, easy to clean
• Charcoal filters: Required for ductless installations
