What to Consider before Buying the Best Window Fan
Fan size –
Before you purchase a window fan, the first thing you need to consider is the size of the fan. A big window fan doesn’t necessarily mean better cooling. Smaller window fans can circulate air pretty quickly than big ones. A small window fan with bigger blades will move air faster than a big fan with smaller blades. You need to measure the size of your window and look for the fan that fits your window size perfectly. Also, consider the inner measurement of the window in order to have the best fit. If you have a window that is out of shape, you may have to rebuild the window size to fit the fan you intend to purchase. Alternatively, you may need some more mounting items to install your window fan for a perfect fit. And if you have windows that are of different sizes, you shouldn’t have a problem finding window fans that are already custom-made for windows of different sizes and shapes.
Fan placement –
Proper placement of your window fan will make it work more efficiently. A wrong placement will make you feel like the fan is faulty from day one. Many usually choose the room with the largest window believing that more air can be pulled in through larger windows if all spaces are well closed up. This is a wrong consideration. What is important is the wind direction. The best way to maximize the use of a window fan is to place it where there is constant wind. This ensures better and quicker cooling. The wind is used to complement the existing airflow. But if you live in an area where wind flow is not consistent, you may need to invest in windows fan with a reversible feature which automatically draws in air and push out stale air depending on the direction of the air. Another option to adopt is to place more than one fan in your room. You can place an exhaust fan in warmer rooms.
Fan safety –
Safety is paramount when installing window fans. Consider the safety of children when installing window fans. Don’t place the fan too low to reach the hand of children. This may cause injury. The fan must not be installed at the expense of family safety. Don’t install an inward blowing window fan without its protective screen. This could be very dangerous. Always read the instructions on the fan before installation. Do not use the fan for the purpose it was never meant for. This can damage the fan too early. Always ensure that the fan is static.
How to install a window fan?
Installing a window fan can effectively cool your room especially when the air outside is cooler than the one inside. Aside from that, window fans consume less energy. A window fan has a built-in thermostat that automatically turns off the fan when the temperature reaches the set point and turns on itself when the temperature rises above the set point. There are no tools required for installing a window fan. Most of the window fans are able to fit perfectly on the double-hung windows frame. When installing the fan, you have to lift up the lower window frame and place the fan well into the window frame. Lower the fan carefully to ensure that the fan sits well and ensure it is supported by the window frame.

How to use a window fan?
Using a window fan is not rocket science. It is as easy as using a baseboard heater. If you want the fan to last, you must learn how to use a window fan effectively. These are the Dos and Don’ts of a window fan.
- The more, the merrier – The number of fans that you install in your home would determine how cool your home would be. Try to set up an equal number of in-blowing and out-blowing fans in larger rooms. This helps to create a lot more cooling pressure inside the home. This also helps prevent bugs from entering your home.
- Proper positioning – Proper positioning matters when installing your window fans. Always position the inward-blowing fans on the shady part of the building and the out-blowing fans on the sunny part of the building. Strategic positioning of the fan is very germane.
- Size is important – As a matter of choice, it makes sense to go for the largest-sized fan in the market so as to fit your windows properly. Ensure that you block the open-air cavities on both sides of the fan. Normally, this aspect should be taken care of by the installer of the window fans.
- Avoid installation in waste areas – It is not proper to situate your window fans near the waste or parking areas. Doing this would help you from inhaling unpleasant odour or toxic vehicle exhaust fumes that are unhealthy for your body.
- Check your furniture – Using window fans can cause fluctuations in temperature. Extreme temperatures can affect your furniture or musical instruments like the piano. It makes sense to closely watch these items when you are using window fans.
How to clean a window fan?
Cleaning a window fan at least once in a year is a part of the maintenance of the fan. Periodic cleaning of a window fan is very important because window fans gather a lot of dust and grease over time. Cleaning the window fan helps to improve the functionality of the fan. Here is how to clean your window fan.
Unplug the fan and remove the grill
To avoid electric shock, do not clean a fan when it is still plugged in. Remove it from the plug before cleaning. Place the fan on a flat surface before you start the cleaning. Unscrew the grill of the fan with a screwdriver if the grill is screwed up. If the grill is held together by a release button, press the button to free up the grill and carefully pull it out.
Clean up the fan blades and fix the grill
Make a mild soap solution, deep a soft cloth in the soap solution and start to clean the blades in a circulation motion. Don’t allow water to drip into the mechanism of the fan. Make sure you dry the blades completely with another dry towel before using the fan. Clean the grill too. Then, return the grill and secure it properly and plug the fan to start using it.

How to oil air-conditioner fan motor?
Air-conditioners depend on fans to pull in air through its condenser coils so as to easily dissipate heat. The fans gather specks of dust over time. This is why fan air-conditioner motor requires periodic oiling to keep it functional for a longer timer. It makes sense to oil the fans at the start of any cooling system. It is also an opportunity to check the fan blades and its motor. Below is what you need to do before oiling your air-conditioner fan motor:
- Turn of the power – Air conditioners have high-voltage. As such, you would need to turn off the air conditioner before you go into the compressor cabinet. If the air-conditioner has a breaker, it makes sense to turn it off from the breaker. Ensure that you turn it off from the two sources. Be very careful because air-conditioners have high-voltage capacitors that hold electricity even when it is turned off. Do not go into the unit unless you are sure of where the capacitor is situated.
How to oil?
Air-conditioning units are never the same. This is why you have to strictly follow the manufacturer’s instructions for oiling the unit. Make use of high-quality oil made for speed motor shafts and bearings. Avoid using oil laced with detergents like the oil made for cars.
- Turn off the A/C as mentioned earlier from the two sources
- Remove the cover of the compressor or condenser. The fan motor is situated at the underside of the compressor cover. Use a screwdriver to unscrew the nuts.
- Turn the cover upside down to see the ports on the fan motor. Check the fan blades too.
- There is a plug covering the oil port. Remove the plug
- Drop some oil into each port of the oil. Wipeout overflowing oil properly
- Return the plugs into the ports
How to use a box fan on a window?
Box fans are usually square-sized compact fan that can be used on the window. Box fans have fast-spinning blades for air circulation that provides a quick cooling effect. It is portable making it easy to be placed in an open window or on the floor. You can place the fan outwardly or inwardly depending on the level of the heat outside and the temperature inside.
When you use one fan:
If you intend to use just one fan, turning the fan in or out will be dependent on the temperature outside. If you have a cooler temperature outside than the temperature inside the room, then, you would have to let the fan face inside so as to blow in cool air. This can be done in the night or morning when the air outside is cooler. As the temperature gets warmer later in the day, you have to turn the fan to face out the window in order to drive out warm air in the room.
When using two fans:
If you have two box fans, you can use them for cross-ventilation. Open one window and place the fan there facing out. Then, open the opposite window and place the fan facing out. This helps to enhance air circulation.
You can never go wrong with window fans. Window fans are highly economical and they consume less energy when compared with energy-hungry air-conditioners. Set yourself free from hot and humid temperatures and move into comfort with breezy window fans for your utmost satisfaction.
