If you're unable to invest in an air conditioner during the summer, you might want to consider using fans throughout your house to keep cool. Fans are generally cheaper to buy and install than AC units. Plus, they are better for the environment because they use less energy. Fans are far more energy-efficient and cost-effective.
But fans only work effectively when you use them correctly. Below, a simple guide on how to use the different types of fans properly to keep cool at home.
Window fans are installed in open windows to draw cold air in and push hot air out, and can be set up to cool an entire house. Here are three tips for how to use window fans most effectively. In order for window fans to cool your home, the outdoor temperature must be lower than the indoor temperature.
That's going to be at nighttime or early in the morning. Window fans are installed with a fitted sheet metal mounting that slots into an open window and seals around the edges. So, you don't have to worry about opening or closing that window. However, other windows in your house should remain closed during the hottest part of the day and — when safe — open at night and early morning.
Window fans work best when you use more than one to create a crosswind, which pushes the hot air out and draws the cool air in. To do this, setting the fans up in the right location is crucial.
If you live in a multi-story home, place the inward-blowing fans on the lower floors where it's cooler and the outward-blowing fans on the upper floors. This method will rid your home of the warm air rising to the upper stories. Ceiling fans circulate air in the room by pushing it down. However, they can not lower the temperature like a window fan or AC unit.
But they can still cool you down. That's because their breeze creates a slight wind chill effect that can help sweat evaporate from your skin, which cools you down. When weatherpeople talk about wind chill on a cold winter day, what they are referring to is how the wind increases convective heat loss see How Thermoses Work for details on convection. By blowing air around, the fan makes it easier for the air to evaporate sweat from your skin, which is how you eliminate body heat.
The more evaporation, the cooler you feel. Sign up for our Newsletter! Mobile Newsletter banner close. Mobile Newsletter chat close. This covers a longer area for air circulation and dispersing the cool quickly through the room. Using a fan allows you to adjust the settings on your AC.
It does not need to be on full blast or set at a very cold temperature setting, that costs more money, to cool the home. On average, a box fan costs less than two cents an hour to run. Not only will the temperature get lower, so will your energy bill.
For those who use window air conditioners, fans can create an indoor cross-breeze that can carry cool air from room to room. Position your fans to blow the cold AC air toward the hot spots in your home or apartment. On a hot day, the air in your home rises close to the ceiling, while the cooler air sinks to the floor. By manipulating the air flow in your home with strategically placed fans, you can shift the air to more evenly distribute it.
This air flow shift creates a more comfortable temperature. Utilize your fans so that cold air is moved up from the floor.
