Hi there! I’m John Roser. Ceiling fans are a great way to make your space feel more spacious, but they also help provide air circulation. HVLS Ceiling Fans are great for people who work in hot areas with lots of windows. These are big industrial fans that are used to cool homes and other buildings on a daily basis. Now, these types of fans were actually created by heat transfer specialists and scientists who were looking to find a way to keep people comfortable while they worked or while they slept.
