🧰 Should I Upgrade My Rangehood Ducting? Here’s Why It Might Be Worth It

If your kitchen always seems smoky, your rangehood sounds like a jet engine, or cooking smells linger long after dinner — your ducting might be the problem.

Many people focus on the rangehood itself, but the ducting is just as important. Upgrading it can dramatically improve performance, reduce noise, and help you stay compliant with Australian building standards.

Here’s why upgrading your rangehood ducting could be a smart move for your home 👇

🌀 1. Better Airflow = Better Performance

The ducting is the pathway that carries air, steam, and odours out of your kitchen. If it’s too narrow, crushed, or has too many bends, it restricts airflow — even with a strong motor.

✅ Upgrading to a larger or smoother ducting system (e.g. from 100 mm to 150 mm) can:

• Improve suction power
• Clear out steam and smoke faster
• Make your kitchen feel fresher and more comfortable

---

🔇 2. Quieter Operation

If your rangehood sounds loud but doesn’t seem to be doing much, the culprit may not be the motor — it’s often the ducting.

Cheap flexible ducting creates turbulence and air resistance, which increases noise.
✅ Switching to rigid, smooth ducting can:

• Reduce noise levels
• Improve airflow
• Make your cooking space more pleasant

---

🧼 3. Less Maintenance & Longer Lifespan

Poor ducting can collect grease, dust, and moisture over time. This buildup can:

• Lower performance
• Create unpleasant smells
• Shorten the life of your rangehood motor

Better quality ducting means less cleaning and a longer-lasting appliance.

🧱 4. Compliance & Warranty Protection

In Victoria (and most of Australia), rangehoods should be externally vented — not just recirculated into the ceiling.

Poor or non-compliant ducting can:

• Fail building inspections
• Cause moisture damage in the roof space
• Void your rangehood warranty

✅ Upgrading ensures you’re meeting Australian standards and protects your investment.

🛠 When It’s Worth Upgrading

Consider upgrading your ducting if:

• Your rangehood is noisy but weak
• Steam and smells linger in the kitchen
• Your current ducting is flexible foil or crushed
• You’re renovating or replacing your rangehood

👉 The best setup is usually a short, straight run of 150 mm rigid ducting that vents directly outside with a proper external vent and backdraft flaps.

💡 The Bottom Line

Upgrading your ducting isn’t just a cosmetic upgrade — it’s a performance booster for your rangehood. You’ll enjoy:

• A quieter kitchen
• Stronger suction
• Easier maintenance
• Compliance peace of mind

If you’re already planning a kitchen upgrade or new rangehood installation, this is the perfect time to make the switch.
