However, many property owners believe that they shouldn’t purchase an attic fan to cool their attic because nobody uses it. The attic’s temperature can have a detrimental impact on the temperature of the rest of your home, thus that is why. Your air conditioner must work harder if you are spending money to run it but the attic continues to be sweltering hot.

Well, in this article I’ll be discussing about attic fan as the following questions will be discussed:

Ok, let’s dive in!


What is attic fan?

An attic fan is exactly what it sounds like—it’s a fan that is mounted on the attic ceiling. In order to function, it pulls hot, muggy air from your attic and expels it outside. This strengthens your HVAC system and provides much-needed ventilation.

However, did you know that attics may reach temperatures of more than 160 degrees during the sweltering summer months? Consider what that would do to your home’s temperature.

What are the types of attic fan?

Many people are guilty of ignoring their attics, which are occasionally utilized as storage. They are susceptible to shifting weather and temperatures, just like roofs, which could have an impact on how comfortable your home is. As your attic absorbs the heat from your roof, attic fans are an energy-efficient technology that helps your attic cool down.

However, they guard against mold growth and roofing system damage during the cold and wet seasons.

Below are the types of attic fan:

Attic Vent Fans


Attic vents moderate summertime heat just like whole-house fans.

However, attic vents can help prevent ice dams from harming your gutter and roof shingles.  An attic vent simply extracts warm air from your attic, unlike entire house fans. Then, your soffits and the cold, dry air from the outside are drawn inside by the vents. By doing this, your roof can maintain a cool temperature, preventing snow from melting on heated regions and forming ice dams.  It’s not necessary to leave your attic vents open all the time.

Your attic vents are controlled automatically by devices like a thermostat, timer, or humidistat, which also lowers your electricity expenditure. Make sure there are no openings in your attic for best results.

Whole House Fans


Whole house fans can quickly chill your home if you need something to do so. The fan can quickly pull in cool air from the outside and push out heated air from within thanks to the air exchange process. For better air quality, they also eliminate allergies, pollen, and other contaminants. Install this fan only in open, vented attics so the air may escape. It is typically installed between the attic and the living area.

However, moisture could become trapped and encourage the growth of mold. For a cooler breeze in the morning or evening, keep your entire house fan on. Consult a specialist to determine whether you require a ducted whole-house fan, a regular whole-house fan, or an insulated door whole-house fan.

Solar and Electric Attic Fans


Furthermore, not as strong as an electric fan, a solar-powered attic fan or roof vent does greatly enhance airflow in the attic. Your attic can get up to 150 degrees during the hottest months if you don’t have an attic fan. The fan maintains a constant airflow through the attic, but if too much air is exchanged between the attic and the outdoors, moisture from snow and rain can seep in. A humidity management system in your attic is also advised in regions of the country with significant humidity or wetness to stop moisture problems. Rooftop and gable end electrical/solar attic fans are the two most popular models.

However, solar-powered models are the most expensive yet use green electric power, electric fans are more powerful and cost-effective. Any attic fan you install should include a programmed thermostat and a first, which turns the fan off in the event of a fire, no matter what you decide. To keep pests out of your attic, stay away from plastic options and choose for versions that are entirely made of metal and have sturdy screens.

Attic Insulation

Is the insulation in your attic good? Because hot air rises, a poorly insulated attic will continue to let interior warm air into the attic during the winter and will radiate heat into the house like a furnace during the summer.

However, make sure your insulation is sufficient before you even think about installing an attic fan.
