One of the best ways to save money on cooling your home is to install a whole-house fan along with an attic fan. Summer may be ending, but there are still many warm and humid days ahead. Do yourself and your energy bill a favor by installing an attic fan that will lower the temperature and lower your energy bills. Attic ventilation fans help cool attic air by blowing suffocating hot air inside the attic and bringing in cool air from outside.
This prevents warm air from leaking into your home and raising the temperature in the living space, reducing the load on the air conditioner. In most cases, a whole-house fan is mounted on the attic floor, above a rectangular grille on the ceiling of a central corridor. If you have appliances that use natural gas or propane, an electric attic fan can cause exposure to carbon monoxide. There are a wide variety of sizes and styles of attic fans to choose from, and your SESCOS electrician can help you select the right one.
They won't make your roof last forever, but attic fans can reduce wear and tear, improving the years of use you get from your roof and delaying costly replacement costs. These fans can provide a home with 30 to 60 air changes per hour, depending on the floor plan, climate, and fan size of the house. A whole-house fan and an attic fan, working together, can cool your home enough to replace your air conditioner, even on the hottest days. However, many users claim that an attic fan is a money saver, but they don't offer documented proof of the savings.
You can tell if your home has negative air pressure by slightly opening a window while the attic fan is running. During the cold winter months, attic fans exchange and move air the same way, but with a different purpose. The air of makeup isn't something that a lot of people think about on a regular basis, but it's important when talking about attic fans. The potential for hazardous conditions is greatest in homes that use power extractors during the summer, when gas appliances are turned on at the same time the fan is turned on.
It may start to seem like attic fans aren't worth it and could cause more problems than they solve. Due to negative reviews about attic fans over the past few years, owning one won't increase a home's resale value. Also, if your water heater or oven is located in the attic, then an attic fan will not be the best solution for your home. Finally, because attic fans require you to leave windows open throughout the night, they don't always make sense in neighborhoods that have safety concerns.
By drawing damp, stagnant air out of the attic, attic fans help prevent moisture from building up and ultimately help create less inviting conditions for mold.
