Attic ventilation may not be at the top of you mind, but it is an aspect that can help keep you home cool and efficient. Attic fans used in the Dallas area are often installed with humidistats as well as thermostats. Since humidity is common in the Dallas area, an attic fan with a humidistat is a good choice. Attic fans are a great way to improve your home energy efficiency. Radiant Barrier and high efficiency A/C units are other options for improving the efficiency of your home and saving on utility costs.
If you attic is not properly ventilated, it will store hot air. The hot air can reduce comfort and increase your utility bills. The answer to this hot air is to install an attic fan. Attic fans are inexpensive and are designed to only run when needed.
On average, a home should have 1 sq ft of attic ventilation for every 300 sq ft of attic space. If you’re not sure if you attic is getting too hot, you can see some visible signs on your roof. Look for shingles that have the corners turned up or bulges in the felt. In the cold winter days, you can check for frost inside the attic. In addition, check your soffit vents to make sure they aren’t clogged with debris. Any clogged air vents should be cleared to help the attic breathe properly.
When choosing at attic fan there are several things to consider. There are two basic types, those designed for a roof mount and those designed to be mounted on a gable wall. In the Dallas area, a roof mount is the most common attic fan installation. There are many variations of these types of fans.
Traditional Store Type Fan
A Traditional Store Type Fan can be used to move a lot of air. However, they do leave a hole in the roof that isn’t insulated. These attic fans are also noisy and require maintenance.
Solar Powered Attic Fans
Solar Powered Attic Fans are one of the best options. Not only are they powered by light, but they are very quiet. The overall cost of these attic fans are also less and the maintenance is very low. If you live in an area where sunlight might not be visible for several days, it is possible that the solar powered attic fan will stop running when needed due to low power. However, that is rare in the Dallas area since we have routine sunshine all year long.
Electric Attic Fans
Electric Attic Fans are another option and, as you can tell by the name, they are powered by electricity. They involve a little wiring and will increase your utility costs, especially in the summer when the attic fan is frequently used.
Wind Powered Fans
Wind Powered Fans rely on natural energy to function. You have to install turbine vents to allow wind access, but they are a great option for those trying to go green.
