Because heat becomes so intense in the attic, it is important that all homeowners have a proper attic vent fan. Although you could choose one of the top brands currently on the market, if you are interested in saving money and choosing an environmentally friendly solution, you might consider an energy efficiency product that can draw hot air from the attic but without the high cost of using a fan that runs on standard electricity.
Of course, just as an energy efficient fan would pull hot air from the attic vents, remove stagnant air that may have a foul odor, dry out trusses, and save money each month on utility bills, the right fan would also be beneficial during the winter months. In this case, venting would prevent moisture buildup that ultimately leads to the growth of mold and mildew. In both cases, your home would be more comfortable and a healthier place to live.
One of the best solutions would be to use a fan to vent the attic along with some type of insulator that would stop infrared heat that hot roofs emit. With this, the interior of the attic would be much cooler but by choosing alternative power, the cost to achieve the goal would be minimal. Keep in mind that within the United States, specific codes have been established specific to attic ventilation. However, because these codes are the same regardless of climate, the best option would be a ventilation system that works for everyone while saving money.
Since demand for a house attic fan that runs on alternate power is so high, most of the top manufacturers now offer their own version of an energy efficient unit. As a result, when shopping for the right exhaust system, you have a full range of products, as well as features and price structures. While this is great news, the one mistake you want to avoid is purchasing a solar powered fan that is under powered. Unfortunately, this problem is all too common. Therefore, when looking for the best ventilation system for your attic remember it would be better to purchase too much power than not enough.
