Why Should You Buy Attic Fan?

An energy efficiency attic fan is convenient. It only utilizes a fraction of the energy that your air conditioner consumes. The fan also minimizes your monthly utility expenditures, as it reduces the run-time of your AC.
Adjustable Thermostat
Some attic fans have a wi-fi connection. This allows you to control the temperature from your phones. These appliances have a small metal box installed next to them. It allows you to modify the temperature setting. Adjust the button as per your requirements and the attic fan will maintain that.
Can Keep Upstairs Cooler
A house’s thermal comfort can be improved by installing a fan in the attic during the summer. Sometimes, despite the AC being turned on, you may notice that the temperature inside the house is getting hotter. This is caused by radiant heat from the attic. A good attic fan can help keep heat out of your home. Your upstairs will stay cool and cozy with air sealing techniques and adequate insulation.
Less Possibility of Damaging The Roof
The heat and moisture that form in your attic can be harmful to your roof’s structure. Over time, this may lead to damage. You can extend the life of your roof by removing excess moisture and thus, installing an attic fan is a must.
How to Adjust the Thermostat of an Attic Fan?
Most attic fans include a thermostat in their design. You should adjust the temperature dial to a temperature higher than the current attic temperature. Once you hit 90 degrees in the attic, the fan should kick on. When the dial lowers below 90 degrees, the fan will turn off. The manufacturers recommend setting the thermostat between 105 and 115 degrees. Make sure also to monitor how often and how long the fan runs.
How Long Can You Run an Attic Fan?
Attic fans should run until it replaces the indoor air with that of outside. This task usually takes about 15 minutes to complete. By dividing the strength of the fan by the volume of the attic space, you can get a more accurate estimate of the time. Regularly operating a fan will make the ventilation system more efficient. This offers a pleasant and energy-efficient home.
Where Should You Place the Attic Fan?
