Recently I’ve been living next to someone who I’m convinced sets their air conditioner to about 20C (70F). I’ve heard it turn on when I have been very comfortable both inside and outside. At the same time I reckon that they probably have their heater set not much below that, so they always stay right at the same temperature year round.
The recommended temperature to set your air conditioner to is 25C (77F). This is the best setting to balance the economy of running your air conditioner and setting it to a comfortable temperature.
Some people find 25C to be too warm to set the air conditioner to. If that’s the case for you then running a fan is an economical solution to help augment cooling provided by the air conditioner. My personal preference is to run the fans on high with the air conditioner set to 25C rather than setting the air conditioner any cooler then that.
I have a few friends who really crank down their air conditioner at night because the like to be cold when they sleep. To help us sleep at night in the summer we leave the air conditioner at 25C, set the fan to high and remove the duvet from our duvet cover, so we just sleep with the duvet cover. This helps us to sleep at a comfortable temperature, without increasing the costs to cool the house.
What temperature do you have your air conditioner set to and what do you do to make your air conditioner cool your house more effectively?
