How a house fan can cool your home

How a house fan can cool your home

Keeping your home at a comfortable temperature throughout the summer can be a daunting task. Fortunately, there are solutions to ever increasing energy bills such as solar panels, energy efficient windows, insulation and cool roofing that can help provide relief during hot summer months.

In the long run, these options are excellent money savers, but they can come with a large initial cost. There is one affordable solution that is widely overlooked by homeowners and is an excellent way to beat the heat in the summer months: installing a whole house fan. 

Whole house fans work by pulling cool, fresh air into the home and pushing warm air out. It seems counterintuitive, but a whole house fan should be turned on when the temperature begins to drop in the evening or early morning and shut off as the temperature outside begins to rise. 

House fan draws hot air into the attic and out through the roof vents. This creates negative pressure in the living area which pulls cool air through the windows. Whole house fans work rapidly, cooling the home in minutes. The house temperature can combat the increasing heat because it’s started the day at a much lower temperature than even a house cooled by an air conditioner. 

In mild climates, a whole house fan can eliminate the need for air conditioning, and in areas known for harsh summers, it can significantly reduce the usage of an air conditioner. The operating costs of whole house fans are less than the cost of using an air conditioner and can save homeowners up to 80 percent on energy costs

Whole house fans have been used popularly since the 1950s, but they were traditionally noisy. Another problem with older models of whole house fans is the hole that must be cut into the ceiling or wall to install the whole house fan. This hole could allow heat to escape during winter months. 

With today's models, most whole house fans are fashioned to run quietly. When installed correctly and sealed properly, they do not allow the heat to escape in the winter, and some are even insulated to further protect your home from heat escape. 

Installing a whole fan is an inexpensive way to combat the heat in the summer months, but just like any construction project, it is important to use a knowledgeable industry specialist to ensure quality products and workmanship. When used correctly, whole house fans can greatly reduce, or even eliminate the use of air conditioning units, which reduces energy costs, making your home and your energy bill a lot more comfortable.
