How to Install a Rangehood: What You Need to Know
Installing a rangehood is not a typical DIY project — it involves electrical connections, ducting work and cabinet modifications that usually require a licensed electrician and sometimes a licensed plumber or gas fitter. But understanding the installation process helps you plan your kitchen renovation, choose the right rangehood, and have a more informed conversation with your installer. This guide explains the installation process for ducted and recirculating rangehoods.
Ducted vs Recirculating Rangehoods
Before installation begins, you need to know which type you have or are installing:
- Ducted rangehood: Vents air outside through a duct in the wall or ceiling. Far more effective at removing smoke, grease, moisture and cooking odours. Requires a duct run to an external wall or roof. This is the preferred type for heavy cooking.
- Recirculating rangehood: Filters air through charcoal/carbon filters and returns it to the kitchen. No ducting required. Less effective than ducted but can be installed in apartments or kitchens where external ducting is not possible. Requires regular carbon filter replacement.
What Does a Rangehood Installation Involve?
1. Electrical Connection
All rangehoods require a 240V power connection. In most kitchens, this means running a new circuit from the switchboard to a dedicated powerpoint or hardwired connection above the rangehood. This work must be performed by a licensed electrician in all Australian states.
2. Cabinet Modifications
Most built-in and canopy rangehoods require the overhead cabinet above the cooktop to be either removed or modified to accommodate the rangehood body. This work is typically done by a cabinet maker or skilled handyman.
3. Ducting (for ducted models)
Installing a ducted rangehood requires:
- Determining the duct route (through the wall behind the cooktop, through overhead cabinets to the ceiling, or through the ceiling to an external roof vent)
- Cutting through wall or ceiling material to create the duct run
- Installing aluminium or rigid steel duct (100mm or 150mm diameter, depending on the rangehood)
- Fitting an external wall cap or roof vent with a flap to prevent cold air and pests from entering when the rangehood is off
Longer duct runs and duct runs with multiple bends reduce airflow. Minimise the duct length and bends wherever possible. Never use flexible corrugated ducting for the entire run as it significantly reduces airflow efficiency.
4. Mounting and Securing
The rangehood body is mounted to the cabinet or wall using the manufacturer's supplied brackets. Ensure it is mounted at the correct height above the cooktop:
- Electric/induction cooktops: 650–750mm minimum above the cooktop
- Gas cooktops: 750–900mm minimum above the cooktop (check the rangehood manufacturer's specification)
5. Final Connection and Testing
Once the rangehood is mounted and ducted, the electrician makes the final electrical connection. The rangehood is then tested on all fan speeds and lighting modes to confirm correct operation.
Can You Install a Rangehood Yourself?
The electrical connection must be made by a licensed electrician in Australia. Cabinet modifications and ducting work can be done by a competent handyman in some jurisdictions, but many tradespeople offer full installation services. If you are replacing a like-for-like rangehood (same size, same duct position, existing power point), the installation is simpler and less expensive. A new rangehood in a new location, or a ducted rangehood where none existed before, is more involved.
How Much Does Rangehood Installation Cost in Australia?
Typical rangehood installation costs in Sydney:
- Like-for-like replacement (existing duct and power): $200–$400 (electrician labour)
- New installation with ducting through wall: $500–$1,000+
- New installation with new cabinet modifications: Add $200–$600 for cabinetry work
- Roof duct installation: Add $300–$600
