How to Install a Rangehood: What You Need to Know
Replacing or installing a rangehood involves electrical work and, depending on the type, ducting. This guide explains what's involved so you can plan properly and understand what a professional installer will do.
Types of Rangehood and Installation Requirements
Ducted Rangehood
A ducted rangehood extracts cooking air and exhausts it outside via a duct. This is the most effective option — it removes heat, moisture, grease and odour rather than recirculating them. Installation requires:
- A duct path from the rangehood to an external wall or roof
- An external exhaust grille or roof penetration point
- Appropriate duct diameter (typically 150mm or 200mm round)
- An electrician to connect the rangehood's power supply (240V, 10A circuit)
In homes with existing ducting from a previous rangehood, replacement is straightforward. Installing new ducting in an established kitchen can be challenging if the path to the exterior wall involves going through cupboards, walls or ceiling cavities.
Recirculating Rangehood
A recirculating rangehood (also called filterless or ductless) pulls air through grease filters and carbon filters, then recirculates the cleaned air back into the kitchen. It doesn't require external ducting. Installation involves:
- Securing the rangehood to the wall or underside of an overhead cabinet
- Connecting the power supply (can be hardwired or plugged into a GPO)
- No external ducting needed
Recirculating is more flexible for placement but less effective than ducted at removing heat and moisture. The carbon filters require regular replacement (every 6–12 months depending on usage).
Canopy vs Undermount vs Island Rangehood
- Wall canopy: Mounted to the wall above the cooktop. The most common type for residential kitchens. Available in ducted or recirculating configurations
- Undermount (slide-out): Slides out from under an overhead cabinet. Less visible when not in use. Generally less powerful. Usually recirculating
- Island rangehood: Suspended from the ceiling above an island cooktop. Requires ceiling-mounted ducting. Requires a qualified installer with experience in island installations
Can You DIY a Rangehood Installation?
In Australia, connecting a rangehood to a hardwired 240V circuit requires a licensed electrician. This is not a DIY task — it's illegal for unlicensed persons to do electrical work in NSW and all other states. A plug-in rangehood (connected via a standard power point) doesn't require an electrician for the electrical connection, but installing ducting is typically best left to professionals to ensure the right seal, path and external exhaust grille.
What Does Professional Installation Cost?
Rangehood installation costs in Sydney typically range from $200–$600 for a straight-forward like-for-like replacement on existing ducting. New ducting installation (cutting through walls, running duct through cupboards or ceiling cavity) adds to the cost — typically $400–$1,000 additional depending on complexity. Island rangehood installation, which requires ceiling penetration and suspension hardware, costs $500–$1,500+ depending on ceiling type and duct path.
