Attic fans are an essential item for any home that has an attic. Many homeowners have hesitated about installing an attic fan because they don’t understand how they work or the advantages of having them.
Many may even reason that since they never go into the attic, there is no reason to install or run an attic fan. However, there are several advantages to having one installed, and there are many reasons that savvy homeowners install and use attic fans.
This article was intended as an introduction to attic fans; we will go over what they are, how they work, and the benefits of having one installed and working.
What are Attic Fans, and How do They Work?
Attic fans are fans that are usually installed behind gable vents in attics. Some attic fan models may also be installed on the rooftop. Contrary to popular belief, attic fans do not typically push the hot air out of your attic. Instead, they push outside air into the attic. While this may seem counterintuitive, it is actually very efficient.
It is better to pull outside air in because the fresh air being pushed into the attic forces the hot and stale air in the attic out through the roof and soffit vents. Therefore the humid, hot, and stale air that would otherwise be trapped in the attic gets constantly refreshed. The benefits of this process are numerous, as we will see below.
The Advantages of Having an Attic Fan:
The main advantage of using an attic fan is the fact that it works as an inexpensive addition to your air-conditioning system. Summer temperatures in most States can easily exceed 150 degrees Farenheight in a typical attic! Even if a home has good ceiling insulation installed in the attic floor, that kind of heat will quickly seep into your house and cause your air conditioning to work overtime.
Since a ceiling fan uses much less energy than an HVAC unit, it will add a lot to your home’s energy efficiency. Many fans are now solar-powered, so they literally cost nothing to keep running during the day when the sun is hottest.
Increased energy efficiency is not the only advantage of attic fans. The increase in ventilation has a very good effect on the structure of the house. Removing humid air reduces the chance of mold forming, and keeps the frame supports in good condition. In addition, a good attic fan will even prolong the life of your roof.
Have you ever had to climb into your attic on a hot summer day? Another advantage of having an attic fan installed is that you will feel a huge difference in the temperature the next time that you have to climb into the attic!
An attic fan is a very easy way to improve the resistance and efficiency of your home. They are cheap to purchase, they are easy to install, and they are very energy efficient. So, if you have an attic fan, make sure that it is on, and if you don’t have one, you should really look into installing one!
