How does a window fan work

  • The fan works by using electricity to power fan blades to bring fresh cool air from outside of your home to the inside or help move hot air outside of  a room.
  • Get an airtight system that sits in your window and helps circulate air.
  • Most fans have one blade that can spin in two directions.  One to help draw air in and one to pull warm air from the room to the outside.
  • Another design is to have two separately controlled fans with a thermostat.  This will provide a more temperate room by turning the fan on and off automatically when cool air is needed.
  • Choosing the largest fan that will fit in your window will help with sealing and with bringing in the cool air.

Why use a window fan

  • Budget friendly option when cooling your home.  Whether supplementing or replacing an air conditioner a window fan will save you electricity, letting the air in your home feel cooler.  It is also an earth friendly alternative to a bigger cooling system.
  • Placing a fan in your windows can help once the sun goes down and temperatures start to drop.  Turn your fan on in the evening and start bringing the cooler air inside.
  •  Using a  fan all night can help bring the temperature down inside your home, so that you start the next day with cooler air.
  • You can also use a  fan in winter when it is no longer needed in your window.  Place the fan in front of a heat source such as a wood burning stove and help circulate the warm air around the room.

What are the Benefits?

  • It can be easily installed without the help of a professional.
  • It can help cool a room during the night when the outside temperature is cooler than the inside of your home.
  • Bringing fresh cool air in will help your room feel more comfortable helping you to sleep easier.
  • The right  fan can also help draw the warm air out of your home and back outside, making your air feel less stuffy.
  • The fan can save you money as it uses a lot less electricity then a window air conditioner or whole house system.
  • It also provides a lower maintenance option for keeping a room cooler.

How to choose the right fan

  • Decide which windows you will need fans for and take measurements.
  • Ensure the fan is the right fit for the window you will be using it, you want a tight fit but not so big that it won’t seal.
  • Decide if you want a simple design or if you would like more advance features such as a thermostat.
  • Be sure that the fans noise level is acceptable for the space it is going in.  A fan for a bedroom may want to be quieter than one placed in a kitchen.

Window Fan VS Air Conditioner
Before discussing different sections, it is first important to note how fans and air conditioners cool the air. The air conditioner cools the room through pumping super-cooled air throughout the room. Fans, however, simply move the air around at a greater speed. This makes the temperature of the air on your skin feel cooler than it actually is.

Electricity Use

If your main concern is utility bills, then you should know that air conditioners will use a lot more electricity than fans do. The most energy efficient air conditioner still use over 2,000 kilowatt hours every year. Fans will use, roughly, 300 kilowatts hours a year. This means you will need over six fans going all at once to equal one air conditioner. If you want to use electricity the best, you will close the vents into unused rooms, and turn off fans after you leave.

Versatility

Portability is also a huge issue, especially if you are looking at moving. It can easier to move and can be used in various rooms. If you find that your new home has a couple rooms that are harder to cool, then having a window fan would be ideal. With air conditioners, unless you get a window unit, you will not be able to pack it up and move. Air ducts, also, cannot be easily moved around to get air to different spots in the house.

Investments

Most air conditioning systems are a huge investment. You will need duct systems set up, an expensive unit outside, and then a thermostat to control it. Even window air units cost a bit and will need maintenance run. However, window fans and oscillating fans are inexpensive. You do not need to connect them to a duct system and there is no need for a thermostat. In addition, you can find fans starting at $10 at most large retail stores. It will only need to be cleaned occasionally due to dust accumulation.

Function

What fans cannot do is cool the room; they will cool you down though. If you need something that provides you with a cool house to walk into, then the air conditioner is going to be the route to go. However, if you want to keep areas of the house cool while you are in them, then using a fan is going to be cheaper in the long run.

Things to do before buying
Before you’re able to select the right window for your home, the purpose it should serve needs to be fully established. If you have other occupants in the home, speak with them about the desires they may have and weigh the advantages and disadvantages to fulfilling each. There are a number of factors to consider.

The Potential Disadvantages

It’s crucial to realize that with any open window, there will be energy loss. This is partially countered by the energy you will save with the cooling factor of the fan.In most scenarios, you will want to be able to remove your window fan with ease before leaving town or going away for a night. Lastly, the appearance is a vital factor; many homeowners simply do not like the look of the window fan. It is often suggested that you select a window facing your backyard or away from the street and neighbors.

Despite these potential disadvantages, window fans are remarkably useful contraptions that will bring in fresh air and even take out any “bad” air with the turn of a switch or the push of a button. The benefits is greatly outweigh any disadvantages, and so long as you lay out your needs and make your purchasing decision appropriately, you’ll be happy with your window fan for years to come.

Making the Best Decision

A common mistake that homeowners make is assuming that one window fan all they’ll need. Don’t jump to this conclusion hastily! Go around your home and spend some time in different rooms to test the air quality and circulation level of each. Despite the increased cost, you may find it’s well worth it to purchase multiple window fans to ensure the air quality and resulting comfort of your home is maximal.

Determining the number of fans you’d like to place throughout your home will allow you to proceed in narrowing down an ideal, but still reasonable, price range for your purchase or purchases. If you do determine your house will benefit the most from multiple window fans, you may have to think about selecting a slightly lower priced model than originally planned. This is the route that I went down, and I’m still greatly pleased with the results.

The type of living condition should be another avenue to consider when selecting the type of window fan. If it is a smoky environment or is a clean home and you just need air to be moving for perhaps an older parent. If it for an older couple, you should consider the most energy efficient. It will be running all day and especially night. Typically a fixed budget is involved as well.

Make sure to measure the dimensions of your windows. You’ll be taking your measurements with you when you head out to conduct your purchase. Find each window’s width (left to right), height (top to bottom), and depth (outside window seal edge to inside window pane) with as much accuracy as possible. Additionally, check to make sure you have an outlet close to these windows to power the fans with.

Once you’ve gathered your needs from a window fan, the measurements of the affected windows, and your desired price range for the entire project, you can finally begin your search for the perfect model. You can look around locally or conduct specific searches that meet your criteria and order from online.
