Are attic fans good or bad? In this informative video, I focus on your attic fan's role in maintaining a cool and energy-efficient home as the warmer months approach. Highlighting a common yet often overlooked problem, we explore how unsealed attics—with their gaps, cracks, and holes—not only diminish the efficiency of attic fans but also lead to significant energy waste and inflated utility bills.

Citing the U.S. Department of Energy, I highlight that homeowners can save up to 15% on heating and cooling costs by air-sealing their homes and adding insulation in key areas, including the attic【1】. Additionally, the information in this video supports Energy Vanguard's Dr. Allison Bailes' blog post titled "Is It Ever Helpful to Use a Powered Attic Ventilator?" 【2】.

Through actual demonstrations and thermal imaging, this video provides a slightly different perspective on thinking about an attic fan - either the one you currently have or the one you may be considering purchasing and installing.

The big tip in this video is that you should inspect and seal your attic to ensure the optimal performance of your attic fan. By underscoring the importance of well-sealed attic space, we equip viewers with the essential knowledge to enhance their home's energy efficiency, reduce cooling expenses, and maximize the effectiveness of their attic fan.
