Exhaust Fan Services We Provide

Bathroom Exhaust Fan Installation

A properly installed bathroom exhaust fan removes steam and moisture before it soaks into your ceiling, walls, and grout — preventing the mould and peeling paint that come from poor ventilation. We install all types of bathroom exhaust fans including standard ceiling-mounted units, ducted inline fans for bathrooms without direct roof access, and 3-in-1 units that combine a heat lamp, LED light, and exhaust fan in a single fitting.

For bathrooms without a window, the National Construction Code requires mechanical ventilation that either runs continuously or is interlocked with the light switch and includes a run-on timer (keeping the fan running for at least 10 minutes after you leave). We install compliant systems with run-on timers as standard, so your bathroom meets current requirements without you having to think about it.

If your bathroom already has an exhaust fan but it’s noisy, weak, or venting into the roof cavity rather than outside, we can replace it with a modern unit and run proper ducting to an external vent. Venting into the roof space pushes moisture into your ceiling insulation and timber framing — exactly where you don’t want it.

Kitchen Exhaust Fans

Kitchen exhaust fans and rangehoods remove cooking fumes, grease, and steam at the source. The NCC requires kitchen mechanical ventilation systems to achieve a minimum extraction rate of 40L/s, higher than bathrooms, because of the volume of moisture and airborne contaminants generated during cooking. We install ceiling-mounted kitchen exhaust fans, wall-mounted units, and can advise whether a dedicated rangehood would be a better fit for your kitchen layout. If you’re after a full rangehood installation, see our dedicated rangehood installation page.

Laundry & Utility Room Ventilation

Laundries generate substantial moisture, especially from dryers that aren’t externally vented. An exhaust fan in the laundry prevents condensation buildup on windows and walls, and keeps the room fresh. We install wall-mounted and ceiling-mounted exhaust fans in laundries, garages, and utility rooms, sized correctly for the space.

Exhaust Fan Replacement & Repairs

If your existing exhaust fan is noisy, rattling, pulling weakly, or has stopped working altogether, replacement is usually more cost-effective than repair, modern fans are quieter, more energy-efficient, and often have better extraction rates than the original unit. We’ll remove the old fan, check the wiring and ducting, and install a new unit that fits the existing cut-out wherever possible. If the cut-out size differs, we’ll modify the ceiling neatly.

Which Exhaust Fan Do You Need?

Choosing the right exhaust fan depends on the room size, whether you have existing ducting, and what features you want.

Fan Type	Best For	Ducting Required?	Noise Level	Features
Ceiling-mounted (standard)	Small–medium bathrooms with roof access	Recommended (can vent to eaves)	Moderate	Basic, affordable
Inline ducted	Bathrooms far from external wall/roof, long duct runs	Yes (part of the system)	Quiet (motor is remote from the room)	Ideal for noise-sensitive installs
Wall-mounted	Rooms with an external wall, laundries, garages	No (vents directly through wall)	Moderate	Simple, no ceiling work
3-in-1 (heat/light/exhaust)	Bathrooms needing heating and ventilation	Recommended	Varies	IXL Tastic, Clipsal Airflow — all-in-one solution
Window-mounted	Kitchens, older bathrooms with window access	No	Can be noisy	Budget option, no ceiling work

Why Proper Ventilation Matters

Poor bathroom ventilation is the number one cause of mould in Sydney homes. When steam from a shower has nowhere to go, it condenses on cool surfaces, ceilings, walls, mirrors, window frames, and creates the damp conditions mould thrives in. Over time, this leads to stained ceilings, peeling paint, deteriorating grout, and in severe cases, structural damage to ceiling plaster and timber framing.

Beyond mould, inadequate ventilation can aggravate respiratory conditions like asthma and allergies. The National Construction Code (NCC 2022) updated its condensation management requirements specifically to address this issue, requiring bathroom exhaust systems to achieve at least 25L/s extraction and, in most new builds, to duct exhaust air directly to the outside rather than into the roof space.

If your home was built before the NCC 2022 changes, your bathroom ventilation may not meet current standards. We can assess your setup and recommend upgrades that solve the moisture problem properly.

Moonlight Electrical did a great job installing our ceiling fan. On time, professional, and everything works perfectly. Highly recommend!”

I recently had a new fuse installed by moonlight electrical group along with a Level 2 electrical upgrade and couldn’t be happier with the service. The electrician was friendly, professional, and took the time to explain everything clearly. The work was completed neatly and efficiently, and you can tell they really care about doing the job properly. Everything is running perfectly now.

Moonlight Electrical have delivered outstanding fit-outs across our Bankstown and Wilton campuses, along with stunning decorative lighting installations in several of our other centres. The addition of these illuminated hanging features has truly elevated the look and feel of our new spaces, and Moonlight Electrical have been instrumental in bringing that vision to life.

Alanis and Alan are incredibly flexible with scheduling, work efficiently, and are an absolute pleasure to collaborate with. No job is ever too big, and the results consistently exceed expectations. The photos speak for themselves, exceptional work, every time.

We had Moonlight Electrical go down to our rental property in Bulli to fix some flickering lights. They came at a time that suited our tenant, fixed the issue quickly, tidied up after themselves and were very reasonably priced. 10/10 would recommend.

Antonio Batach

If you want honesty and reliability, look no further! Alanis was absolutely great to deal with and really did an exceptional job on our project. His work is like none I have seen before, quick, honest, and exceeding expectations. Would highly recommend!!

Adam Gregory

Had this sparky around to do a few jobs at my place and honestly couldn’t fault him. Turned up when he said he would, got straight on with it, and knew exactly what he was doing.If you need a good, reliable electrician, I’d definitely recommend him. I’ll be getting him back for anything else that needs doing.

Frequently Asked Questions

Do I need an electrician to install an exhaust fan?

Yes. In Australia, any electrical work, including hardwiring an exhaust fan, must be carried out by a licensed electrician. This applies to new installations, replacements, and even swapping a fan for a different model if it involves any wiring changes. Plug-in fans don’t require an electrician, but hardwired ceiling and wall fans do.

How much does exhaust fan installation cost?

A standard bathroom exhaust fan installation typically costs between $200 and $400, depending on whether ducting is required and how accessible the ceiling cavity is. A 3-in-1 unit (heat lamp, light, and exhaust) generally costs $350–$600 installed. Ducted inline systems requiring longer duct runs may cost $500–$800+. We provide a fixed-price quote before any work begins, so there are no surprises.

Should an exhaust fan be ducted to outside or into the roof space?

Ideally, to the outside. The NCC 2022 requires exhaust systems in new builds to discharge directly or via a duct to the outdoors. Venting into the roof space pushes warm, moist air into your ceiling insulation and timber framing, which can cause condensation, mould growth, and long-term structural damage. For existing homes, we can retrofit ducting from your current fan through the eaves, soffit, or roof to vent externally.

My exhaust fan is noisy — should I repair or replace it?

In most cases, replacement is the better option. A noisy exhaust fan usually means worn bearings or a failing motor. Modern fans are significantly quieter, more energy-efficient, and often have higher extraction rates. We can install a new fan in the existing cut-out in most cases, keeping the job quick and cost-effective.

What size exhaust fan do I need for my bathroom?

As a general rule, your exhaust fan should extract at least 25 litres per second (25L/s) for a standard bathroom. For larger bathrooms or those with a spa bath, you may need a higher-capacity fan. We’ll assess your room size and recommend the right capacity to ensure effective moisture removal.

Do you install exhaust fans with timers?

Yes. For bathrooms without a window, the NCC requires the exhaust fan to be interlocked with the light switch and include a run-on timer that keeps the fan running for at least 10 minutes after the light is turned off. We install compliant timer systems as standard for windowless bathrooms, and can add timers to any exhaust fan installation on request.
