Ventilation fans are also referred to as whole house fans. These fans pull outside air into a building and circulate it around the interior. They are most commonly installed and used in residential areas. When combined with other cooling appliances, like ceiling fans and window or portable air conditioners, ventilation fans can work very well at cooling a home in any climate.
One of the most obvious ways that a ventilation fan can use too much electricity is if it is too small for the building or home that it is installed at. Fans that are too small will work extra hard to circulate air, which in turn causes a rise in cooling costs. To reduce these cooling costs it is essential that the right sized fan is used and that it is installed properly.
Solar powered ventilation fans are also making an appearance on the retail market today. These fans use the power from the sun to function properly. There are complete ventilation systems and single attic fans that are available for purchase and use. Such ventilation fans make great use of a renewable energy source, which is a perfect way to cut electricity costs during the summer.
Some property owners may also use the existing components of their centralized heating system as a ventilation fan during the summer months, but this does require some modifications that will need to be completed by a knowledgeable person or heating and air conditioning professional. If modified correctly, a centralized fan can be an energy saver as well.
