All of us are used to using air conditioners but every time we get our summer electric bill month, it still surprises us. The bills just seem to increase every month so it is practical to look for other cooling devices that won’t cost you as much as air conditioning units. It´s a good thing that there are all sorts of fans that you can choose from including a whole house fan.

A whole house fan allows you to save money because it does not use up that much electricity compared with air conditioning units. It can be installed in any type of house whether you have a newly built home or an old one.

2 main purposes of installing whole house fans

•    Cooling purposes
•    Ventilation purposes

If you are using the window fan to cool your home, you can opt to get a whole house fan and attach it to your ceiling to freshen the entire house. The fan will act as an exhaust where warm air is drawn out and released outside. In order for cool air to come in your home the windows need to be opened.

If the reason for getting a fan is to remove odors in areas of your house particularly the basement, you can get a basement window fan and this can be installed on a window frame in your basement. It still makes use of the same process wherein the fan removes stale air carrying it outside of the house passing through the opening in the fan.

Other parts of the house that could also benefit from the use of an exhaust fan to get rid of odors are bathrooms and kitchens.  You can buy a window mounted fan that you can simply fit in your window so you won’t need to create a hole for it. These window fans often have adjustable side panels that you can bring up or down depending on the size of your window. This will cover any gaps between the fan and the window frame to prevent insects from getting into your home.

Using installed fans are preferable in places where the climate is mild like tropical areas. The best time of the day to turn on your fan is early in the morning or at night where the temperature outside is cooler than the temperature inside the house.  For the rest of the day, it is best to use freestanding fans that circulate the air and create a cooler atmosphere from the movement of air, rather than transfer of cooler air from outside.

Basement Window Fan

Keeping your basement free from all kinds of smells can be difficult especially because most basement windows are small.  The small window opening does not provide enough air flow to get rid of odors that can develop in the basement. The best way to remedy this problem is by installing an exhaust fan in your basement. Exhaust fans work efficiently in removing stale air and moisture in any areas of the house, particularly the basement.

An exhaust is also a great solution for mold and mildew in your basement.  Humidity can result in the production of moisture in different parts of your basement where mold and mildew can thrive. In time, these areas prone by mold and mildew can become damaged leaving your basement looking unattractive and also an unhealthy environment.  Let us first understand where these moisture is coming from so we can effectively address the problem.

Formation of moisture

The warm air is the culprit in the production of moisture. The warmer the air, the more humidity it can produce. When the warm air cools it gives of moisture. So when the warm air in your basement comes in contact with cold surfaces like your appliances or the walls or windows, those surfaces will become damp.

Air circulation

Dampness in your basement is reduced when there is proper circulation and a basement window fan can give you adequate circulation. If your basement is large with a lot of stored items, consider getting a twin window fan. You might also have to get rid of some things that you won’t need in your basement to ensure that the air can flow freely within various areas of your basement so there will be proper circulation to avoid the formation of moisture.

There are 3 types of exhaust fans: window fan, wall fan and whole house fan.

The window fan is the most common type of exhaust fan that is available. It is fitted in a window hole and it usually comes with an adjustable side panel so if the window is huge, you can just adjust the panel to cover the holes then install the fan.

Wall fans are fully installed fans that require a certain amount of planning and are not generally installed after the building of your home is completed.  This means that you have to create a hole on the wall which is of the same size with the wall fan so you can install it. This is useful if your windows have nice view and you don’t want to block the view by installing window exhaust fans.

A type of exhaust fan that vents through the attic is called a whole house fan. When using a whole house fan, you need to open the windows so it can draw air in to cool the room. The problem with a whole house fan is that the breeze that comes in can bring pollens and other allergens which might cause allergies to members of your family.

Twin Window Fan

A twin window fan can be simply be identified by the two blades you will see inside the fan. The blades are placed side by side. This type of fan can be adjusted in 3 levels: low, medium and high. The two blades can either work as one or they can work separately depending on how you set it up.

One advantage of a twin window fan is its ability to fit into almost any size window.  Twin fans come with adjustable side panels, so no matter what the size of your window is, the fan will surely fit.

There are all kinds of exhaust fans available with the main function of keeping the room temperature at a comfortable level. A whole house fan is just one of the many examples of fans you can find in the market.  It can lower the temperature of a room in a matter of minutes.  However, a cool outside temperature is needed so the fan can supply adequate relief inside the room.

How exhaust fans work

–    Exhaust fans like a whole house fan or a window mounted fan are positioned in strategic areas of your home. Usually it is mounted in your attic or in different areas within your home.
–    The fans work best whenever the temperature outside is lower than the temperature inside of the home.
–    The cool air then enters the room resulting to a much lower temperature
–    Some air inside the room, particularly the warm air is pulled towards the attic by the fan further lowering the temperature.
–    The air in the attic is expelled outside due to the positive pressure or the whole house fan system.
–    Negative pressure is created in different areas of the house thus cool air is drawn from the outside.

Disadvantage of exhaust fans

–    Unfiltered air comes in through the open window, bringing in particles such as pollens. This can pose a problem if someone in the house is allergic to pollens and the like.
–    The fan can create too much noise especially old models. The sound is created by the rapid rotation of the fan blades.
–    During winter, heat can escape through the ceiling if the opening is not insulated or closed securely.

Home owners are gradually realizing the many benefits they can achieve when using an exhaust fan. They don’t only have lower electric bills but they are also helping in the green movement which aids in protecting our environment.  Thus an exhaust fan is a practical addition in any home particularly in tropical areas where the temperature is usually moderate to warm all year round.
