Running a fan is significantly cheaper than running an A/C unit because you can target rooms you're utilizing instead of your entire home. However, a more important question is whether a fan meets your cooling needs. A fan alone may or may not keep you cool, so the trick is to use the fan in conjunction with your air conditioning. Fans do not actually cool the air, so if you’re stuck in an 85-degree room you’re just having 85-degree air blowing on your skin. This trick can save you hundreds of dollars each year, so in short, yes, fans definitely save money! Check out this blog post for more info!
