THINGS TO CONSIDER BEFORE BUYING A WINDOW FAN

1. WHY DO YOU NEED A WINDOW FAN?

Do you live somewhere warm? Does your kitchen get too stuffy even with the windows open? Is a regular fan not enough to cool most of your rooms? If you answered yes to all of these questions, then you need a window fan because your home needs better ventilation.

Are you bothered with your electric bills shooting up every time you turn on the AC? If yes, you also need a window fan as it can effectively offer a cheaper alternative to running the air conditioning all day long. Window fans can efficiently pull in cool air from the outside and then pull out the hot air from our home. While it doesn’t really do much for humidity, it can still help cool your home without spending so much on utility bills.

2. Is your home ideal for using a window fan?

One of the most important things to know about window fans is that they may not exactly work the same way for every home. Some houses can get the best benefits from these appliances, while others might get the opposite of its intended effect.

Do you have windows that take a good amount of breeze? Is the outside temperature in your area cooler than indoor temperatures? Are your windows away from garbage piles and other things with the foul odor? If you can answer yes to all of these, then your home can actually be benefited from a window fan.

3. What type of fan do I want?

To know what kind of window fan you want and need for your home, you might first want to get to know your options. You can choose from single reversible fans or twin window fans.

The reversible window fans come with a single blade that you can switch to either serve as an exhaust fan or to pull in cool air from the outside. The twin window fans, on the other hand, have two blades that you can set up to pull in cool air, push out hot air, or do both at the same time.

Twin window fans are heavily preferred by many because of its efficiency. By simultaneously pulling in cool air and pushing out hot air, it can definitely do more for your home’s cooling. As the two types aren’t that far apart in terms of prices, you might want to go for the twin type instead.

For a room with smaller windows but a large space, dual window fans can be good cooling solutions. One fan of the dual window fan can be set up to pull in cool air and another can be used to solely pull out hot air in stuffy rooms. It all really depends on the air circulation situation of your home, so make sure to weigh your options carefully.

4. Where am I going to place the window fan?

A window fan can be used inside a large size bedroom if the air conditioning system doesn’t have enough capacity to cool this kind of large room. Or it can be used in a large size room as a secondary cooling system. We often see window fans are also placed in kitchens as these rooms tend to heat up most often. Also, they are also seen to use as a bedroom fan to remove the stuffiness of this place. We recommend using a dual window fan since we think that they can work best in these areas. However, if you want to use multiple single window fans in different areas, instead of using a dual window fan. To get the best results, place a window fan in a shady window so that you can get cool breeze at any time. It’s also best to place these fans on the ground floor of your home. Don’t put it near garbage bins or parking lots, though, as doing so will pull in bad odors as well.

5. How many window fans I need for better comfort?

This largely depends on how big your home is and the purpose of your window fan installation. Most of the cases, a single unit of dual window fans is already enough to cool an average size kitchen or bathroom or bedroom. Some like to put one in each room as well.

6. What’s the size of the fan?

The best thing about single and dual window fans is that they come in lots of different sizes. The best way to find the right match for your home is by measuring your windows to know which ones will fit accurately inside your window. You can also opt for a smaller unit since there are extenders that will secure the fan into place. They also seal off space in between the fan and your window frame, ensuring optimal airflow.

7. How powerful does the fan need to be?

As experts say, the more powerful the fan, the more effective it will be to pull in cool air and push out warm air. However, you should still assess the room’s needs as an overly powerful fan can be very overwhelming. To know just how powerful a window fan can be, look at its CFM (cubic feet per minute) rating. This will tell you how much air the fan can move.

8. What features do you want?

Do you want a window fan that can do more than just blow air? There are tons of different extra features various models offer. You might want to look for the more useful ones like remote control, variable fan speed, or even a thermostat among other things. Be careful of products with too many bells and whistles, though. They might not really offer better performance but only heavier price tags.

9. Does the window fan create noise?

Does white noise bother you? One of the drawbacks of fans is that they can create some noise while in operation. This is particularly true if it’s set in the highest fan setting. This shouldn’t be bothersome as long as they don’t exceed 60 decibels which is the same volume of a normal conversation. Considering that you won’t really always place your head right next to the fan, this volume can get lower and less noticeable even more.

Use of Window Fan

  • The main use of a window fan, during summer, is to reduce the temperature of a room by pulling hot and warm air from that particular space to outside.

Don’ts:
