Installation Guide: Common Mistakes to Avoid When Setting Up Your Range Hood

Introduction

A Under Cabinet Range Hood is only as effective as its installation. Even the most powerful hood can underperform if mounted incorrectly. Unfortunately, installation mistakes are common—and costly.

This guide highlights the most frequent errors people make when setting up range hoods and how Branohome helps homeowners and contractors avoid them.

Mistake 1: Wrong Mounting Height

• Too Low: Creates a fire hazard and interferes with cooking.
  
• Too High: Reduces suction efficiency and lets smoke escape.
  

Branohome’s Rule of Thumb:

• Wall-mounted/under-cabinet hoods: 24–30 inches above stovetop.
  
• Wall Mount Range Hood: 30–36 inches above stovetop.
  

Mistake 2: Ignoring Vent Direction

• Ducted hoods: Must vent outside, not into the attic.
  
• Mistake to avoid: Venting into ceilings or walls without proper ducting, leading to grease buildup and fire risks.
  

Mistake 3: Using the Wrong Duct Size

• Problem: Undersized ducts restrict airflow and overwork the motor.
  
• Solution: Match duct size to Insert Range Hood outlet (usually 6–8 inches).
  

Mistake 4: Excessive Bends in Ductwork

• Each bend reduces airflow by ~10%.
  
• Limit bends to 2–3 maximum for best performance.
  

Mistake 5: Forgetting to Seal Joints

• Unsealed joints cause leaks, noise, and efficiency loss.
  
• Always use foil tape, not duct tape, for airtight seals.
  

Mistake 6: Overlooking Electrical Requirements

• Many hoods require a dedicated circuit.
  
• Improper wiring can cause power loss or safety hazards.
  

Mistake 7: Not Considering Make-Up Air

• Powerful hoods (over 400 CFM) may depressurize the home.
  
• Solution: Install make-up air systems in airtight homes.
  

How Branohome Simplifies Installation

• Clear manuals with diagrams.
  
• Convertible models (ducted or ductless) for flexibility.
  
• Professional support line for contractors and DIYers.
  

Conclusion

A well-installed hood maximizes both safety and performance. By avoiding these common mistakes, homeowners ensure their Branohome range hood delivers quiet, efficient, and long-lasting ventilation.
