A properly installed ceiling fan makes a Sydney summer bearable without cranking the air-con. We install every major brand — Hunter Pacific, Beacon, Fanco, Big Ass Fans, Martec — with the correct bracing between the joists so there's no wobble, no droop and no dust cascade twelve months later. If you're replacing a noisy, dying fan we take the old one and its remote away and leave the new one balanced and silent from day one.
Adding a fan where there's currently only a light? That's a bracing and wiring job, not just a swap. We install a proper fan-rated bracket rated for the extra weight and torque, run a switch drop if you want a wall controller instead of a remote, and reconfigure the ceiling rose to carry both the fan and the light on separate switches.
Bathroom exhaust fans get the same care — we duct them properly to the eaves rather than blowing damp air into the roof cavity (a huge cause of mould in Sydney terraces). Combined fan/light/heat units are a specialty; we install the switching, isolate the heat lamps to their own RCBO, and vent the moisture where it belongs.
