Window Fans: An Alternative to Air Conditioning

Should You Buy an Air Conditioner or a Window Fan?Should You Buy an Air Conditioner or a Window Fan?

Window fans are a cheaper and a more earth-friendly alternative to air conditioning. Window fans can be used to cool a home in the evening utilizing the air from outside, The result is that no air conditioning needs to be used throughout the day as the home has been cooled by the morning air. Window fans also help to reduce electrical usage and cost as electricity is being used at non peak times.

How Window Fans Work

Window fans are utilized to expel the warm air from an area or to attract fresh air into an area or room. They usually come with a mounting kits and side panels to support the fan and prevent air from circulating around and back into the fan.

It is usually better if the existing air in the room (the warm air) has a way of leaving the room. This is usually done by the use of a dual twin reversible window fan. If there is not, it could cause a performance loss of 8-10 percent. Smaller window fans might come with the panels attached and some window fans allow the window to be closed with the fan mounted in the window frame.

To cool a room with a window fan, run the fan on intake with a second window open. The 2nd window acts as a vent. If you’re attempting to cool one or more room you should run the fan on exhaust. The windows and connecting doors of the rooms being cooled should be open. A number of features worth looking into on window fans are a thermostat control and electric reversibility.

To ensure to get the most out of utilizing a window fan to cool a home, don’t leave the fan on all day. This shortens the fan’s life, particularly if it’s left on during a rainstorm. Additionally don’t operate a fan that isn’t working correctly. In case the blades are not moving or if there’s a burning odor, it might be a fire hazard. One other problem might be if the fan isn’t lubricated enough. This makes the blades to rotate slowly, not at all and/or make a lot of noise.

Window Fans With Thermostats

A thermostat control on a window fan is useful when there’s a large difference between the night and day temperature. Electric reversibility implies that the window fan is able to switch from intake to exhaust or vice-versa without manually rotating the fan around. When utilizing a window fan, be aware that they do not enable you to control the internal room temperature as closely as a traditional window mounted air conditioner.

When Not to Use a Window Fan

Window fans shouldn’t be used if the air outside is uncomfortably hot, humid and/or polluted. Window fans should not be used without window screens because insects and animals might enter the home. They may also not be used in noisy areas as well. For example, a bust street level home next to a pedestrian sidewalk, may not be a good place to install a window fan. The fan could bring in car exhaust and other pollution, as well as not be a barrier to the noise of the cars, trucks and pedestrians.

However, in most cases, and in most places in the United States, a window fan can be used on most warm or hot days instead of a traditional window air conditioning unit.
