Oh Yes!!! And Yes/maybe!!! I live in the tropics and I could never manage without my wonderful ceiling fans in every room!! I do use the air conditioners during the day in summer here WITH the fans to help circulate that lovely cool air.
But by night I am so cold thanks to extremely good insulation in the ceiling and also the walls,that I go to bed with just my fan on.I really dislike sleeping in an air conditioned room! I have a very bad arthritic disease and I seize up if sleeping in the cold.Little wonder that I left Melbourne many years ago to come up north!!!
Oh I wish I lived somewhere hot enough to need ceiling fans! Our central heating is on full blast all day long at the moment, just trying to get the house to a reasonable temperature.....
When I lived in Singapore I had a ceiling fan in my sitting room and I loved it. It was completely inadequate for cooling the room during the day though, so I used the aircon then but at night it was lovely to relax on the settee and watch the fan looping round hypnotically. I also loved the iconic fans in the Long Bar at Raffles Hotel, they were a top tourist destination on the island.
We love our ceiling fans. We set them on S for Summer and W for Winter. Although we have ducted air-conditioning, we find the fans are sufficient and we only use the air-conditioning about 6 times in summer and most mornings for a half hour or so to warm the house in Winter..
We have ceiling fans and I love them. At night a fan is enough to let me sleep. We have a split system in the kitchen which blows into the lounge room. We use the ceiling fan in the kitchen to circulate the cool air into other rooms.
Yes I have ceiling fans in the bedrooms, lounge, family room and kitchen/diner. Also have air con in master bedroom, lounge and family room. I tend to use mainly ceiling fans and, when it is too hot or humid, put air con on for a while. Don't like the "whirring" sound of ceiling fan above my head in the bedroom so run air con briefly to cool room before bedtime, and then use floor fan.
