How Does a Window Fan Work?

The working mechanism of window fans is different from that of other fans. Typically, window fans operate in two ways.

Window fans work to cool and refresh the air inside the room by either drawing cold air from the outside or expelling the stale air from the inside.

Some window fans can achieve both functions by changing the direction of the rotation of the blades.

Another option would be to get two different fans. One for letting in the fresh air and another for letting out the warm air. These fans could be placed on different windows to maximize their functionality.

Advantages of Having a Quiet Window Fan

You may be wondering whether you need a window fan. Sure, it costs money and will continue to do so after the purchase. So, is it worth it?

Here are some of the advantages of having a window fan.

1. Reduce energy bills associated with the AC system

AC utility bills can get high, especially during the summer.

Having both the AC system and a window fan work during such time can help you reduce your bills significantly.

2. A great alternative to the AC system

A window fan can also be used in place of an AC system. It is much more affordable than the system, resulting in significant budget cuts.

It also helps in cooling the home without all the costs that come with having an AC system running.

3. Fresh air circulation

Your house is home to several odors from different sources. Without proper air circulation, it can get stuffy and lead to air-related complications.

A window fan is great at ensuring the air in your home is constantly circulating to remove any unwanted smells immediately.

Included in the packaging are instructions, sling panels, and mounting hardware.

For households where there are children or toddlers, it is advisable to use the fan in a mounted position. This also prevents it from falling outside the window.

The fan has 3 speed settings which can be changed using the front-mounted rotary control. Although generally quiet, the fan can get a bit noisy on its highest setting.

It would, therefore, not be ideal for use as a bedroom window fan.

Many window fans do not come with the option of versatility.

However, as compared to other window fans on the list, the Holmes Twin Window fan is quite noisy when in operation which can be inconvenient for use in the bedroom or when having conversations.

What to consider when buying Window Fans?


The amount of noise that your window fan produces is an important factor.

Given that the fan will probably be running for several hours each day, you will want to get a fan that is not too noisy.

Newer models of window fans are much quieter and you will not have to worry about them interfering with your conversations even when on the highest settings.

Size of the Fan

The fan is going to be fitted on your window. As such, it should be an almost perfect fit. If the window fan is too big, you may end up incurring extra costs to buy another one should it topple over.

On the other hand, a small window fan will have the same air circulating back and forth.

Sealing the gaps between the fan and the window could help curb the problem of local circulation.

type of the fan

Window fans fall into two major categories: intake fans and exhaust fans.

Intake fans usually pull cold air from the outside into the room.

Exhaust fans, on the other hand, work by expelling the warm unwanted air in the room to the outside. 

Choosing between the intake and exhaust window fans will depend on many things. However, to be on the safe side, you can simply get a fan that incorporates both features.


If you are going to get a fan that performs both the intake and exhaust functions, reversibility is an important factor to consider.

Some window fans require manual reversibility. This can be quite inconvenient as you have to remove the fan from the window and flip it around.

A better option would be a fan of electrical reversibility.

Through the push of a button, you get to switch to whatever function you want. With remote control, switching between intake and exhaust functions gets even more convenient.


Before you decide on what window fan to buy, it is important that you consider whether or not the fan is safe, particularly if you have children and pets in the house.

The fan’s blades should be made of soft material. Even better, they should not be exposed to avoid any accidental injuries.

Ideally, a window fan that has a screen is a better option. It will help keep insects and rodents from getting into the house. It also prevents burglars from using that window to gain access to your house.


Your window fan needs to be powerful enough to draw in the fresh air and dispel stale air from the room. Of course, the more powerful your window fan is, the better performance it will provide.

Ease of Use

You certainly do not want to get a window fan that will have you spend hours just to get it started. Consider getting a fan that comes with features that make it easy to use the appliance.

Some of these features should include different speed settings, remote control, multiple blades, and extenders. The fan should also be easy to clean.


Just like any other home appliance, window fans range in price. An expensive fan may not necessarily be more effective.

Have a budget for the window fan. Go ahead and do some research on the different fans available that are within your budget to get the best deal.

Installing a Window Fan

If you are not sure of your DIY skills, then you should get a professional to install the window fan for you.

However, if you would like to get a bit handy, these tips should help you install your window fan easily.

1. Choose the location

The location of your window fan will have a huge impact on its performance. Have the window fan face the direction of the wind. It should also be installed in the coolest area of the house.

If you are going to use two fans, have them placed across from each other in a room. This will help to promote cross-ventilation. The fan should also be placed at least 1.7 meters from the ground.

2. Take some measurements

For energy efficiency, the window fan needs to fit snugly into place. Measure the chosen location for the fan and ensure that it is right.

It is also possible to get fans that are designed to fit the window frame perfectly. These usually come with expandable panels that let you cover any spaces.

3. Cut the glass

Utmost precision is needed for this step. Use the appropriate tools to get a clean cut. For accurate results, mark the glass before cutting it to make your work easier.

4.Install the fan

Installing the window fan correctly will require some knowledge of electrical and wiring work.

You should also comply with the IEE (Institution of Electrical Engineers) regulations. Ask for professional assistance if you do not know what exactly you need to do.

5. Connect to the power

The last step is connecting the fan to the power depending on the instructions provided by the manufacturer.

Extra Tips:

  • Do not install a window fan if the area you live in is close to a garbage area, garage or any area with unpleasant odors. The unpleasant smells and toxic fumes will be drawn into the room.
  • Avoid placing a window fan near the fridge or freezer as this will increase the electricity load
