How to Choose Attic Fans and Vents

An attic fan can help preventing the temperature in your attic from increasing to an insufferably hot degrees. An attic fan can do such thing by dispelling the hot air in your attic and reducing the temperatures of the upper-level space in your room by ten degrees, extending the durability of your roof shingles as well as helping to cut down expenses for air-conditioning up to thirty percent. Several studies have shown that having a proper attic vents may improve the efficiency of the energy and help preventing the dams of ice from forming along the eaves whenever winter comes. A properly-working attic ventilation is also important to prevent moisture and mould damage, as well as prolonging the usability of the roof shingles. This article will explain several things about the attic fans in hope that it can give you good considerations when choosing it.

Types of Attic Fan

Attic fans are either solar or electric. Basically, it comes in two basic types; there’s the rooftop attic fan which has a shape of a dome and is waterproof, and there’s also gabled-end circular fan which is mounted to the inside part of the gabled vent. An active attic vent is a term used to refer to an electrically-powered fan which can exhaust the air from inside an attic. It is used for attic ventilation as is also commonly known as PAV or powered attic ventilator. A passive one on the other hand, does not require electricity for it to run. Instead, it relies on air currents as well as natural convections in order to circulate the air through different kinds of attic ventilation. PAVS are typically installed in the house’s gable end, and it is connected to a thermostat which would turn the fan on whenever a pre-set temperature is reached inside of the attic. Other type of PAV is the whole-house fan which commonly installed in the hallway’s ceilings and it is created in a way that allows hot air to escape through the attic. Another type or PAV is the one which is waterproof and installed directly on the roof. Like what has been explained earlier, there are some powered attic ventilator which uses solar light as its source of power. Regardless of whether it is powered by solar or electricity, PAVs are generally not an efficient attic ventilation and they may cost energy performance by taking conditioned air out of the space and exhaust them through the attic. The passive attic ventilation on the other hand, is a much more reliable and efficient means of ventilation.

What to Look in a High Quality Attic Fan

It is likely to find certain qualities such as a thermostat which automatically operates the fan, a durable construction made of metal, a motor which lubricated permanently, as well as having a heavy screen which capable of repelling pests. When you are looking to purchase a new attic fan, make sure to take note some of these things.
