Why Should You Choose Your Window Fan Carefully?

Choosing the best window fan BEFORE you buy is important! Otherwise, you may buy a poor quality fan that doesn’t match the size of your room or apartment. Or, the window fan may not do what you intended it to do in the first place.

For example, if you are looking to buy a window fan to supplement your existing air conditioner, you may not need to buy as an expensive model than if you were going to use it every day. However, if you plan to use the window fan a lot, look for a more powerful window fan model. The fans with only average capabilities probably won’t do the job. In addition, improper operation of a window fan might also lead to the unit breaking down or no longer functioning like it should. Also, higher usage of the window fan can also lead to higher operational costs, which in turn, lead to the higher electric bills.

Impotance of pickign the right fan

 

Another important item to pay attention to is the type of window fan. If you are living in an area that has a great deal of air pollution or you live near a busy street with car exhausts, the intake window fan might be a mistake. In these cases, it’s better to consider an exhaust type of window fan, which will push out the stuffy air from inside the room. Also, the size of the window fan needs special attention as well. For example, in the case where your windows are long and narrow, your window fan may not fit the window opening.

Factors To Consider When Choosing A Window Fan

Here are some tips to think about when choosing a window fan.

Size of the Window Fan

As mentioned before, the size of a window fan is one of the key things to pay attention to when buying one. In case you have big, long windows, opt for a twin window fan, so that there will be no gaps in between the window frame and the unit itself.

Having gaps in your window after installing the window fan is highly undesirable since gaps are perfect places for small insects to sneak inside your home. Moreover, these gaps might also be used by criminals in order to get access to your premises, if the window fan is poorly secured into the window opening.

Size of Window Fan

The size of the window fan also plays a large role in relation to the size of the room or your home where it is being installed. If the area you intend to use it in is large, then choose a larger window fan, and vice versa.

Considering the above, we strongly recommend buying a window fan that fully matches the size of your window. However, don’t worry – most of the models perfectly fit into the standard window frames.

Before buying a window fan, measure the size of your window frame and only then start your fan search. Make sure that the unit you intend to buy is easily installable. Moreover, it is important to ensure that the window fan can be removed with ease – for cleaning or other reasons.

Type of Window Fan

The type of the window fan is as important as its size. There are two types of window fans – intake and exhaust. The former type works on the principle of pulling cold air from outside, while the latter exhaust type pushes stale air from inside your home. If you are looking to maximize the performance of your window fan operations, purchase both types of units.

Place the intake fan on the shady side of your house to use it to pull the cool air overnight. Then, install the exhaust fan on the sunny side of your house to use it to push out the hot air from your premises.

Reversable Window Fan

In the same fashion, if you are only looking for one window fan, choose the type according to the intended placement of the unit. In case you want to install the window fan in the sunny side of your house, buy the exhaust type of the fan, and vice versa.

However, there is also a great option to buy a fan that is able to perform both these functions. These window fans feature the reverse function, where you can switch the appliance from intake mode to exhaust and back.

Durability And Safety of the Window Fan

Before buying a window fan, pay close attention to what the fan is made of and who makes it. Choose a window fan made of a strong and solid material in order to ensure longevity of the appliance. In case you have children in your household, think about safety measures before buying and installing a window fan as well.

In order to make sure that the fan is safe to use, pay attention to the blades – you want to make sure they are secured by the outer grill of the window fan.

Consider The Wind Direction for Your Window Fan

If you have lived in your current home for long enough, you probably already know the direction the wind blows around your house. As to be expected, some of the windows usually tend to have cooler outside air. We recommend installing the intake window fan on these windows. This will maximize the efficiency of your window fan, reducing the operational costs of the unit.

House Position Wind

If you are not sure about the direction of the wind in your area or if the direction of the wind is not constant, we would recommend purchasing the reversible type of window fan, so you can adjust the operation mode in line with the changes in the winds.

Noise Level of Window Fans

Some window fans tend to make noise when they are being operated. If you are indifferent to noise levels, you are lucky (unfortunately, I am not) and can basically choose any fan that. However, if you are a light sleeper or just don’t like the sound of a running window fan, make sure you purchase a window fan that operates quietly.

Conclusion

Choosing the best window fan shouldn’t be a chore. Use the above tips to buy the one that best fits your needs. And if you need additional tips and ideas on buying a window fan, download our Window Fan Buyers Guide.

Complete Guide To Window Fans

A complete guide to window fans is given below. It covers what a window fan is and how/why they are used.

Window fans are probably one of the most under-rated appliances on the market today. Yes, they can help cool a house or room, but they can do much more than that. Widow fans can:

  • Window fans can cool a home or whole house.
  • Window fans remove stale air from a room or home & replace with fresh outside air.
  • Window fans remove smoking odors from a room
  • Window fans remove cooking and pet odors from a kitchen or living room
window fans eliminate cooking odor

Yes, who hasn't burned the pot roast, a slice of bread or set the kitchen towel on fire! Even regular cooking - especially frying, can smell up the kitchen or the whole house. 

And what do most people do when this happens? Some people turn on their vents over the stove, but most vents are either too weak to do the job or some even vent the smoke back into the kitchen!

Another option is to open a door or window. But what if the wind isn't blowing? Or there is a pet or small child in the home? The solution? A window fan! Simply turn it on (some units even have a remote control) and within minutes, those nasty smells are out the window.

Of course many people buy a window fan to cool down a room or whole house. Window fans, either a single or double fan, do a great job in either blowing in cooler fresh air or blowing out the warmer air in a room or home. Some double window fans actually do both at the same time!

And we all know how pointless small inside fans are when you are hot. Though they blow air on you, it's the hot air already inside the home! 

Man trying to cool down with a fan

Additionally, many people don't think they can have both a window fan and an air conditioner (either a central unit or a window a/c unit). This is incorrect. A window fan can actually help the existing air conditioner be more efficient and not work as hard. Simply use the window fan for a bit to get the room cooled down a bit, then use the existing air conditioner to continue the work.

Of course, it's not advisable to operate both the window fan and the a/c at the same time. If you do own an existing air conditioner, be sure and purchase a window fan that has a damper or closing mechanism to close the window opening - once the a/c is turned on.

So remember, while short exposures to heat are not dangerous, regular excessive heat might lead to dizziness, exhaustion and other unpleasant effects. Therefore, it is vital to ensure that you properly manage the temperature of the environment where you spend a significant part of your time during the hot season. One of the greatest solutions to beat the heat is a window fan.

Now, let's get into the nitty-gritty and discuss the types, functions, benefits, manufacturers and uses of window fans.

What Is A Window Fan?

A window fan is a special cooling appliance that is created to be placed inside a window frame, and usually have expandable side panels that facilitates covering the window opening completely.

A window fan is a great way to maintain comfortable temperature and purity of air inside a room. These fans not only come at a reasonable price but also are actually great alternatives to a central air conditioning unit. The operational cost of a window fan is low, which helps save on utility bills.

Most window fans have either one large fan or two small ones located next to each other. Also, most units feature two or three operational speeds. Some window fans available on the market are electrically reversible. This feature gives the user an opportunity to switch between intake and exhaust modes.

Window Fan

The older window fan models are made of metal and are somewhat heavy. However, they are more solid in comparison to modern units that are made of plastic.

Over the years, window fans have changed a lot – now you can enjoy a number of different features, such as built-in thermostats and adjustable grills. Thermostats are used to turn the fan off when the temperature in the room reaches a certain level. The adjustable grills are perfect for changing the direction of airflow.

Some more sophisticated models offer advanced electronic features such as a remote control, different speed motor controls and automated shut-down timers etc.

Talking about the diversity of window fans, it is worth mentioning that the options available are wide ranging. Some of the one-fanned units are very energy-efficient and are created for ventilating and cooling a single room. Other more powerful models are able to circulate air through the whole house.

In fact, a window fan has a great advantage in comparison to a room fan – it is able to circulate air within the room, bring in cool air from the outside or push hot/smelly odors from the inside to the outside.

This makes a window fan an ultimate air purifying/cooling appliance. In fact, window fans come in handy not only in regular small square rooms – their functional construction makes it easy for them to deliver fresh air even in irregular shaped rooms or large two story rooms.

In addition to the above mentioned facts, a window fan is a great alternative to air conditioners due to its environment friendliness. If a window fan is properly installed, it is capable of reducing the temperature by 10 to 20 degrees Fahrenheit or more.


How Does A Window Fan Work?

Now, when we already know what a window fan is, it is time to understand how it works. Everything genius is simple – just like the principle behind a window fan’s operations. A window fan operates in one of two following ways:

  • It either pulls in cold air from outside
  • Or pushes out hot/stuffy air from the room
Window Fans Triple

The way you position your window fan will determine the principle of the unit’s operations. There is also a great combinative option to create the perfect environment by installing one window fan to pull in cold air and the other to push stale air out.

However, as we mentioned before, there are some models that offer the reverse function – so you don’t need to use two fans – just change the mode from intake to exhaust and vice versa.

Some modern models also feature two sets of blades that run independently. This allows the unit to push the stale air out and pull in the fresh air from outside at the same time.


What Are The Benefits Of A Window Fan?

  • Affordable, energy saving option. The main reason behind using a window fan is that it is a very affordable and energy-efficient option to fight the summer heat in comparison to air conditioners and central air conditioning systems.
  • Great A/C supplement. These fans can serve as a great addition to air conditioners, if you already use one. Since an A/C is not able to actually clean the air around just as a window fan does, the joint work of these two can ensure clean and cool air is always circulating!
  • Moreover, using both of these appliances simultaneously will further optimize their operations, and, as a result, you can minimize operation costs of your A/C.
  • Fresh air circulation. A window fan can eliminate odors from kitchens, bedrooms, living rooms, and any other area types. The exhaust function comes in handy when your favorite cookies are burnt in the oven!
  • Fit most windows with ease. Most window fan models come with adjustable panels, which allows hassle free installation in a matter of minutes. You need to just take the unit out of the box, fix it onto the window frame with the help of the panels, plug in the device and enjoy fresh air!

However, some models require window screens to be removed. This implies that when the fan does not operate, small insects are able to get through the spaces in the fan’s grill.

Don’t worry, a simple solution for this exists. A special cover for the window fan will make you forget about this issue. It is recommended to cover your fan even if it fits your window perfectly. This will prolong the life of your cooling device by keeping the fan’s motor safe from moisture.


How To Use A Window Fan?

Window fans are a great way to cool down your house without having to pay much for it. This economical, energy-wise cooling option is used alone or as a supplement to an air conditioner. However, if you place your window fan in a proper way, it can even replace the A/C, while saving you money. To make sure that you use the fan in the most efficient way, follow these tips:

How To Install The Window Fan?

Most window fans are able to fit into a standard double-hung window frame. Installation requires you to lift the lower window frame, insert the fan into the frame, and lower the sash back down to ensure that the fans are sealed in place by the weight and support of the window on it.

Some window fan models are customized for sliding windows that open horizontally. They are installed in the same way, following the same principals of the regular vertical ones.

Think About Fan Direction

When humidity rises during the day and the sun is high, hot and stale air is created inside the house. One of the most efficient methods to cool and lower the temperature is to pull cool air in overnight.

Some advanced fan models turn on automatically, when the temperature and humidity outside are lower than what it is inside the house. This feature ensures that the fan is only used when needed by eliminating the need to turn on/off the fan at night. During the warm part of the day, use the window fan to push the hot air out of the house.

Direction of Fans

For this method to work, you will need to find a balance between a fan pushing air out and another fan pulling air in. Ideally, opt for an equal number of fans between the two. Yet, if that is not possible, go for more fans blowing air into your house.

As I have mentioned before, some fans feature reversible blades that allow you to use the same fan to pull in cool air at night and push hot air out of the house during hot days.

Increase Circulation Of Air

You can maximize the circulation of fresh air inside your house with the help of a window fan. In order to do that, you will need to set up a system of window fans.

Place the intake fans on the shady side of your house to use them to pull the cool air in, overnight. Then, install the exhaust fan variants on the sunny side of your house to use it to push out stale air from your apartment.

House Air Circulation Review

In case you live in a multi-story house, install the intake fans on the lower floors, with the exhaust fans on the upper floors. This way, you will make sure that the warm air does not rise to the upper floors. Don’t forget to open as many doors between rooms as possible, for good air flow.

Go Full Mode

Larger fan blades are able to move air more efficiently than smaller ones. Thus, in order to maximize results, opt for a larger fan that can easily fit onto your window. Moreover, you can consider dual and even triple system units to increase overall airflow around your premise.

Aside from fan size, pay attention to the window fan’s efficiency rating. This number will tell you how much air the fan is able to move per minute. Fans with higher efficiency ratings are able to cool the space quicker with more efficiency. They also help cut down on utility bills.

Big Window Fan in Window

In order to perfectly fit a fan into your window, use paper, drapes, or cardboard to fill in the gaps in between the window frame and the unit. This will prevent the air that has already come through the fan from moving around the fan and through it again. Using this technique is especially important for intake fans since the change in pressure will force the air to go back outside.

Window Fan Placement To Avoid

Avoid placing the intake window fans near parking areas or garbage, since the fans will bring smells from those areas into your house. I would also not recommend placing a window fan near freezers or fridges. The window fan can blow cold air out of the appliance quicker than usual when you open it. This significantly increases the load on the unit.

Trash Can Near Window

Moreover, do not place a window fan above valuable items, as this can lead to water damage if the fan is operating during the rains.

Utilize Right Fan Running Time

The key idea behind using a window fan is to bring fresh air inside your house once the temperature of the air outside is cooler than the air inside the house. When the air inside the house is cool enough to counterweight the expected daytime temperature, turn off the fan, remove it from the window and close the windows.


Additional Window Fan warnings and tips:

  • Pulling cool air in at night and pushing out hot air in the daytime will lead to you seeing a 10 to 20 degrees F temperature difference between night and day. This fluctuation in humidity and temperature might appear uncomfortable for some people.
  • In case nighttime air in your region is not as cool as you wish, excessively humid or polluted, using intake fans are not recommended.
  • Important: Make sure that your windows have proper screens. Windows with no screens, with broken or ripped ones, can easily be breached by small insects or animals. Moreover, such windows appear to be an easy aim for criminals.
  • Do not leave your window fans in the window frames during bad weather conditions. Leaving an operating window fan in the window can lead to water or electrical damage in such adverse conditions.

Types Of Window Fans

Most of the window fans look alike – they look likes cages with blades inside the housing. Ain addition, all of the window fan models are intended to fit inside the frame of a window.

Window fans can be classified by the number of blades they feature. The most popular types of window fans are single and twin fans. Normally, most of them have more than one operating speed setting. Moreover, some of the single and twin window fans can be reversed from intake to exhaust modes and vice versa either manually or electronically.

Window Fan 3 Fans for increase air flow

Single window fans feature one set of blades. These type of fans are relatively small in comparison to twin window fans. They are perfect to fit into regular windows and usually come with installation kits.

As you might already have guessed, twin window fans have two sets of blades. These fans are usually bigger than single window fans. Moreover, with twin window fans, you can efficiently maximize the circulation of fresh air inside the apartment by setting one set of blades for intake and another set for exhaust. Like this, you will have fresh air coming in from outside and stale air pushed out from your apartment.
