While air conditioners are nice, they’re often expensive and they eat electricity. Window fans provide an alternate way to enjoy a hot day even while indoors. This simple staple of easy living circulates air through a room. Combined with fans operating in reverse to vent air from other parts of the house, they create a steady, pleasant breeze to create comfortable, inviting spaces. Window fans are often much quieter than air conditioners, and they’re perfect for bedrooms where oppressive heat might already make sleeping difficult. When cooler days finally arrive, window fans are easy to remove and store—at least until the next heatwave rolls through town.
