Heating and cooling account for almost half of your home’s energy costs. Your attic is a major part of the problem—building up heat in the summer and losing it in the winter. A Solar Attic Fan keeps the air in your attic circulating, pulling hot air and moisture out of your attic all year round. In the summer, it helps keep your attic cooler, reducing the strain on your AC. In the winter, it helps prevent moisture build-up and ice damming, which can damage your roof and cause leaks. No matter the season, an Attic Fan can extend the life of your roof, make the air in your home healthier, and lower your energy bills.
