Facts on Ceiling Fans
Question 1: There are many varying opinions regarding ceiling fans. What’s your take on it?
Answer: The CSIRO has done a lot of research into ceiling fans. It concludes that as well as costing a fraction of running air-conditioning for the same room, the stream of blowing air over an occupant can reduce the temperature of the air next to them by 2-3C.
Q2: What rooms do they work in best?
A: Without a doubt the bedroom. With the cooler night air coming in through a partly-opened window a fan should be all you need to be comfortable if you choose the correct-sized blade.
Q3: And what’s that?
A: For a typical-sized bedroom it would be a 48in blade.
Q4: What are the quietest fans to run?
A: Ones with rattan or wooden blades. We find four-blade units are the most efficient.
Q5: Do they cost much to install?
A: We can do a typical installation for around $350 including the fan unit.
