Fans are very useful in hot and humid conditions. In many areas, fans are used in almost every room. While some people may argue the aesthetics of ceiling fans, one thing is sure, they do help elevate that feeling of stuffy hot air and help reduce air-conditioning costs by usually allowing us to turn up the thermostat five degrees or more while remaining comfortable. We recommend keeping other light sources away from ceiling fans to avoid an annoying flicker/strobe effect that may also cause strain to the eyes. Fans come in different styles and applications, from ceiling fans, to wall fans, floor fans, desk fans and even outdoor ceiling fans.
