Unlike standard attic ventilation fans, gable attic fans are cooling alternatives hailed for their easy installation on existing gable vents. To provide ventilation, these durable and effective units are hardwired, plugged into an outlet or solar powered without requiring any sort of modification to your roofline.

Why do You Need a Gable Attic Ventilation Fan in the First Place?

Summer comes with lots of pleasant sun that offers brighter days for most. It is also the season to soak in the warmth and get that much loved tan going. Even insects are abuzz with life and vigor. But summer also brings dreary heat that can be stifling and overwhelming especially if your home cooling system is not performing at its best. Unless you install one of the best gable attic fans.

During a summer heat wave, it’s not surprising that the exhausting heat in the attic can reach as high as 150 degrees Fahrenheit. For most of us, the home cooling and heating can be centered just around the living area of the home and often not much thought is given to the attic.

When you take the time to examine how heat from the summer sun affects your home, it becomes quite apparent that your attic should not to be neglected. That’s because the attic acts as your home’s heat shield and for that reason has a significant impact on the temperature in the rest of the house and living spaces.

In case you have noticed an unreasonable spike in your cooling bills. And your living space is heating up uncomfortably despite your HVAC system operating at full throttle. Then it’s quite possible that your attic is acting up and is playing a role in the rising heat in your living space. But how is that possible when your home has a ceiling that is intact and in good repair?

Well, during summer when the sun is all out, it blasts down mercilessly on your roof and your entire structure absorbs the heat energy. The absorbed heat radiates into the attic space and then finds it way downwards through the home’s framing by conduction. As a result, your living space gets heated up. The natural reaction will be to turn on the AC and crank it to a higher setting in an attempt to regulate the temperature to a more comfortable level. When the energy bill comes, it will be significantly higher than usual because of the stifling heat that your AC has been trying to deal with.

A big part of the solution is in improving ventilation in your attic which will in turn reduce the amount of heat the attic holds and conducts into your home. This is where attic fans can help solve the heat problem.

As mentioned earlier, installation of a gable attic fan is pretty straightforward without altering your roofing. Just needs to be mounted on your gable vent.

By installing a good quality gable fan, you can effectively reduce the cooling load on your air conditioner and thus save money off your utility bills. A gable attic fan does a decent job of ventilating your attic and helps keep the hot air from settling which subsequently maintains a lower temperature in your living space.

Additionally, gable attic fans are also smart automatic units that  come with adjustable thermostats. This way, you can set your preferred temperature levels and let it do the work for you. And once the set temperature levels are achieved, the fan will turn itself off.

Below we look at some of the best gable attic fans that can drastically improve the temperature conditions in the attic and have a positive impact on the efficiency of your AC system.
