Frequently Asked Questions

How do I know if my ventilation fan is powerful enough for my specific room size?

To ensure effective ventilation, you need to calculate the air changes per hour (ACH). For a standard Australian bathroom, you generally require 15 to 20 air changes per hour, while a kitchen needs around 10 to 15. You can calculate the required capacity by multiplying the room’s length, width, and height to find the total volume in cubic metres, then multiplying that by the required ACH. This will give you the necessary “metres cubed per hour” (m³/h) rating. If your ventilation fan is underpowered, steam will linger on mirrors and walls, eventually leading to mould growth and damage to your cabinetry.

Is it better to duct an exhaust fan to the outside or into the roof cavity?

In Australia, it is strongly recommended—and often required by building codes—to duct your exhaust fan directly to the outside air via a roof cowl or a wall vent. Discharging moist, warm air directly into your roof cavity can lead to significant problems, as the condensation can settle on timber trusses and insulation, encouraging rot and mould in areas you cannot see. Using flexible ducting to lead the air outside ensures that humidity and cooking odours are completely removed from the building structure, preserving the longevity of your roof materials and maintaining a much healthier home environment.

Can I leave my bathroom exhaust fan running all night to clear out dampness?

While it might be tempting to leave the fan on, most standard residential exhaust fans are not designed for continuous 24-hour operation and can become a fire hazard if the motor overheats. A better solution for Australian homes is to install a run-on timer or a humidity sensor. These clever devices allow the fan to continue operating for a set period (usually 10 to 15 minutes) after you leave the room and turn off the light, or they automatically activate when moisture levels rise. This ensures the room is fully cleared of steam without wasting electricity or risking mechanical failure.

Why has my exhaust fan become much noisier lately and how can I fix it?

An increase in noise is usually a sign that the fan is struggling with a buildup of dust and lint on the blades or the housing. When dust accumulates unevenly on the impeller, it throws the fan out of balance, causing it to vibrate and create a loud humming or rattling sound. You can usually fix this by safely removing the cover and vacuuming the blades with a soft brush attachment. If the noise persists after cleaning, the bearings in the motor may be worn out, which is a common sign that the unit has reached the end of its functional lifespan and needs replacement.

Do exhaust fans require a licenced electrician for installation in Australia?

Yes, in Australia, any electrical work involving fixed wiring must be performed by a licenced electrician. This includes installing a new exhaust fan, replacing an old unit, or adding a timer switch. A professional installer will ensure that the fan is positioned correctly for optimal airflow, that the wiring meets Australian Safety Standards (AS/NZS 3000), and that the unit is properly secured to avoid dangerous vibrations. They will also provide you with a Certificate of Electrical Safety, which is essential for your home insurance and provides peace of mind that the installation is safe and compliant.
