Attic fans are designed to cool overheated attics by pulling cooler outside air in through attic vents and pushing hot air outdoors.
The key to living a fit life is to bring as much cool, fresh and healthy air into your house as possible. There are several ways to do so and attic fans are considered one of them.
The most cost-effective and energy-efficient approach to cool a building is through ventilation. Are you still unsure whether the answer to your ventilation and air circulation problems is an attic fan? Let us tell you all you need to know about attic fans so you can decide for yourself.
How attic fans work:
Attic fans are a so well named, since their name describes exactly what they are: fans for attics. They are one of the most common attic vent kinds. They circulate the air at the top of your house when installed on the attic ceiling.
When the air outside is colder than the air within your home, an attic fan may be utilized to cool your living area. An attic fan draws fresh air into the house through open windows and doors while pushing out warm air through attic vents.
Benefits of Attic Fans:
To give you the proper idea on why we think attic fans are absolutely worth it for better air circulation and ventilation, we have gathered some facts to support the claim. Here are the benefits of attic fans:
1. Roof protection:
One of the most important and little-known benefits of effective attic ventilation is that it can help avoid premature roof ageing.
During the winter months, moist and warm air from your home mixes with the cold air immediately beneath your roof, resulting in moisture and condensation that collects beneath the roof. Moisture is a roof’s worst enemy, and it may cause costly damage.
Attic fans provide a much needed protection from the moisture and minimize the chances of damage to your roof.
2. Energy efficient:
You may save money on air conditioning by cooling down your attic with the help of an attic fan. The AC will have to work less due to the fact that attic fan is keeping the air cool while also taking care of the hot air.
If your attic is extremely hot, heat will escape into your house, forcing your air conditioner to work harder and more frequently, perhaps driving up your electricity bills. Aside from the increased energy use, running your air conditioner more frequently may prematurely age it.
An air conditioner has around 15-year average life expectancy, however if it is used often, it may only last just less than 10 years.
3. Cool down upper floor of your house:
If you frequently notice that the second floor is never as cool as the first, it’s possible that heat is radiating down from the attic into your living area. An attic fan may assist prevent heat from entering your house using correct air sealing techniques and adequate insulation, making your upstairs cooler and more pleasant.
4. Solar powered attic fans:
If you want, you can opt for the solar powered attic fans too. Slightly higher in price, but these solar attic fans can save you a lot on your electricity bill, while also cooling the house at the same time.
You can always choose the best suited option for yourself as per your need.
5. Insulation support:
Excessive heat and humidity can cause your attic’s insulation to deteriorate. An attic fan pulls hot, humid air out of the attic, relieving pressure on your insulation.
6. Moisture reduction:
During cold or warm weather months, a poorly ventilated attic can contribute to mold formation. During hot weather, the A/C will be blasting cool air throughout the house, while the attic will be filled with hot air.
Moisture and condensation can accumulate in the attic when these two temperatures collide. Mold may develop in the presence of darkness, moisture, and a food supply. If left untreated, mold can cause allergic responses as well as serious respiratory problems. These infestations often go unreported for months since most people don’t spend much time in their attics.
An attic vent fan can help prevent mold formation by reducing moisture in the attic.
Ventilation and air circulation in attic:
Do you have enough makeup or intake air in your attic? In order for an attic fan to function correctly, there must be enough passive venting for it to take air from.
The attic fan will extract conditioned air from the interior of the home if there isn’t enough passive venting in the attic through gable vents, soffit vents, single passive vents, and other sources.
How long should you run the attic fans to achieve best results:
In general, an attic fan should operate for as long as it takes to completely replace the air in the attic with outside air. This usually takes about 15 minutes. However, calculating the power of your fan by the amount of your attic area will give you a lot more accurate time.
Installing an Attic Fan:
