Introduction
When designing or renovating a kitchen, one of the most important decisions is choosing the right rangehood. A quality rangehood not only removes cooking odours, grease, and moisture but also improves indoor air quality. In Australia, homeowners have two main options: ducted (vented) rangehoods and recirculating (non-vented) rangehoods. But which one is best for your kitchen? Let’s break down the pros and cons of each, considering Australian regulations and installation requirements.
What is a Ducted Rangehood?
A ducted rangehood vents air, smoke, and odours outside your home through ductwork, making it the most effective option for kitchen ventilation.
✅ Pros:
✔️ Superior air quality – Completely removes smoke, grease, and cooking odours.
✔️ Quieter operation – The fan motor is often located further away.
✔️ Ideal for heavy cooking – Perfect for gas cooktops and frequent cooking.
❌ Cons:
❌ Requires ducting installation – Can be more expensive if retro-fitting.
❌ Less flexibility in placement – Needs access to an external wall or roof.
When to Choose a Ducted Rangehood?
✔️ If you’re doing a full kitchen renovation and can install ducting.
✔️ If you want maximum ventilation efficiency.
✔️ If you have a gas cooktop (recommended for safety and compliance).
What is a Recirculating Rangehood?
A recirculating rangehood filters air through charcoal filters and releases it back into the kitchen. This is often used in apartments, units, and homes where ducting isn’t possible.
✅ Pros:
✔️ Easier to install – No ducting required.
✔️ Flexible placement – Can be installed anywhere.
✔️ Lower upfront cost – No additional ductwork expenses.
❌ Cons:
❌ Less effective at removing steam and odours – Filters trap grease and odours but don’t vent them outside.
❌ Requires regular filter replacements – Charcoal filters need replacing every 3-6 months.
❌ Can be noisier – Since all air is processed within the unit, the fan works harder.
When to Choose a Recirculating Rangehood?
✔️ If ducting is not an option (e.g., apartments, townhouses).
✔️ If you cook lightly and want basic filtration.
✔️ If you’re making minor kitchen updates rather than a full renovation.
Do You Need a Qualified Installer for a Rangehood in Australia?
While recirculating rangehoods can be DIY-installed, ducted rangehood installation should always be done by a qualified professional.
Ducted Rangehoods & Licensing Requirements
✅ Electrical Work: If your rangehood requires new electrical wiring, only a licensed electrician can perform the installation. DIY electrical work is illegal in Australia and can result in fines or unsafe installations.
✅ Ducting & Ventilation: The National Construction Code (NCC) and Australian Standards (AS 1668.2-2012) specify that rangehood ducting must vent outside the home—not into a roof cavity. A qualified installer ensures compliance.
✅ Gas Cooktops & Safety: If you have a gas cooktop, proper ventilation is essential to prevent carbon monoxide buildup, making a ducted rangehood the safer choice.
Why You Should Hire a Professional
✔️ Ensures compliance with Australian regulations – Avoid legal or safety issues.
✔️ Proper ducting and airflow efficiency – Prevents grease buildup and poor ventilation.
✔️ Right extraction power for your space – Ensures your rangehood effectively removes cooking fumes.
Bottom Line: If you’re installing a ducted rangehood, need electrical work, or have a gas cooktop, always hire a licensed professional to ensure a safe and compliant installation.
Australian Regulations & Considerations
🇦🇺 What does Australian law say about rangehoods?
✅ Gas cooktops & ventilation: According to the Australian National Construction Code (NCC), if you have a gas cooktop, proper ventilation is required. Ducted rangehoods are highly recommended where possible.
✅ Recirculating rangehoods & compliance: These are legal but must have high-quality filters to effectively remove grease and odours.
✅ Duct installation requirements: If installing a ducted rangehood, the exhaust must be vented outside (not into the roof cavity).
Final Verdict: Which One Should You Choose?
🔹 If you want the best air quality and performance → Go for a ducted rangehood (ideal for new kitchen builds).
🔹 If you need a flexible and easy-to-install option → A recirculating rangehood may work, but be prepared to change filters regularly.
🔹 If you’re using a gas cooktop, a ducted rangehood is strongly recommended for safety and compliance.
