A good exhaust fan helps move steam, smells and moist air out of your home so ceilings, walls and
windows stay drier. Electricians and ventilation specialists can supply and install fans in
bathrooms, laundries and kitchens, including ducting them to the outside where required. Post your

Exhaust Fan Installation FAQs
Do bathroom exhaust fans need to be ducted outside?
In many homes, building and ventilation guidelines recommend that moist air from bathrooms is ducted
outside rather than into the roof space. The exact requirements can vary with your location and
building design. Electricians and ventilation specialists can suggest options that suit your home
and help manage steam and condensation effectively.
Can I use an existing light switch for a new exhaust fan?
Sometimes a fan can be combined with an existing light circuit, but in other cases a separate switch,
timer or extra wiring is recommended. A licensed electrician will check your current wiring, load and
switch location before advising on the safest and most practical setup for your room and fan choice.
How long should I run my exhaust fan after a shower?
Many homeowners run the fan during the shower and for 10 to 20 minutes afterwards to help clear
steam and dry out the room. This can vary with room size and how well the space is ventilated. A
fan with a timer function can make it easier to keep a consistent run time without needing to return
and switch it off manually each time.
Can an exhaust fan help with mould problems?
Better ventilation can be one part of reducing mould risk, especially in wet areas, but mould can
have several causes. Improving exhaust fans, fixing leaks, managing condensation and cleaning
affected surfaces may all be needed. Discuss your situation with tradies so they can suggest practical
steps for your home.
