The Best Window Fans To Keep Your Room Cool

The window fan is one of the most inexpensive, environmentally friendly cooling methods for your home, along with ceiling fans, tower fans, and pedestal fans. Although it’s not a substitute for window air conditioning on the hottest summer days, you can stay considerably more comfortable for much less money month to month by choosing the best window fan and learning how to use it properly.

There are many benefits that come with having one or two, or several window fans in your home. But the primary benefit is that window fans can be used to pull in cool, fresh air from the outside or can be used to push out warm and stale air from the room, providing relief from hot weather at a very small fraction of the cost of an air conditioning system both in terms of initial and operating costs.

Installing and operating a window fan in your home can be easy, but the first and foremost thing you need to do is choosing the right window fan that can effectively cool your home. In this article, we’ve listed and reviewed some of the best-rated household window fans available on the market that we think are worth your money.

The Holmes HAWF-2041 Twin Window Fan is our pick as the best window fan for most people. This fan has great quality with a 3-year warranty at a very good price and it comes with most the needed features to keep you comfortable in hot summer days. The only missing thing is that this window fan doesn’t have a remote control.

The motor is waterproof so it is safe to use during rainy weather. The integrated comfort control thermostat helps to maintain your personal comfort level by cycling on and off to your desired setting.

This window fan can cool a room up to 500 sq.ft. It is designed for use in most double hung and slider windows from 24in to 37in width with adjustable extender screen and extender panel.

How Does A Window Fan Work?

A window fan is a cooling appliance that is mounted on a window frame. They usually have expandable side panels that cover the window completely to facilitate the airflow from it.

Window fans cool your home by pulling cool, outside air in or pushing hot air out, depending on which way the fans are facing. Window fans work best in windows that face the prevailing wind or are directly opposite. They are designed to fit into any type of window, double-hung, slider and casement windows.

Most window fans have one, two or three blades with two or three speeds. The standard size is 20 inches window fan, although smaller window fans are also sold. One of the most popular options is the twin window fan. These can also work as reversible window fans.

A reversible window fan let you adjust to changes in the wind direction without having to turn the fan around. By placing two window fans — one blowing in, one blowing out — in windows on opposite sides of a room, you can create cross-ventilation that moves air and makes you feel cooler.

Most of today’s window fans are made of plastic. Many older window fans, however, are made of metal and are more solid. The more powerful window fans can be used to circulate air throughout a house, acting as a whole-house window fan – such as the Air King 9166F 20″ Whole House Window Fan.

The more advanced window fans come with thermostats, LED indicators, and smart features such as timer and automation. But the ideal window fan for most people is the one that doesn’t vibrate and create noise during operation.

Are Window Fans Good for Cooling Your Home?

Window fans have an advantage over other room fans when it comes to cooling the home – they not only circulate the air within the room, but they can also replace the stale air inside the room by continually replacing it with fresh air from outside.

On some window fans, such as the Holmes Dual Blade Twin Window Fan with Water-resistant Motors, they can achieve both at the same time.

Many people don’t know the difference between air intake, exhaust or exchange, when they’re actually just what they sound like. When a window fan’s intake setting is in place, the fan pulls air from the outside into the house. When the switch is placed on the exhaust setting, the fan is pulling hot air from the room and pushing it outdoors. The air exchange occurs when one fan is exhausting hot air outdoors while the other is bringing cool air inside.

Thus, window fans are the perfect choice for home air cooling and purifying. They are perfect for small rooms that tend to get stuffy, but they can also be mounted in windows of large rooms that require a greater amount of air circulation and ceiling fans aren’t enough.

Pros and Cons of Window Fans

Pros:

  • Window fans are budget-friendly and much more energy efficient than evaporative coolers or air conditioners, thus, making them a great choice for cooling your home.
  • When working as an exhaust fan, not only drive the hot and stale air from inside to outside, window fans also eliminate any unwanted odors from your house. So, your home always smells fresh!
  • Window fans are light and portable. So, you can shift them from one place to another at your with the convenience, as long as there is a window.
  • Window fans are very easy to install in any kind of window frame, don’t require having holes on the wall like the ductless mini-split air conditioner.
  • Window fans are generally quiet, making them ideal for bedrooms and night-time use. With a quiet window fan installed in the bedroom, you will feel cooler and therefore sleep better.
  • Many window fans also include thermostats, remote controls, and temperature displays. These are great for providing optimal comfort as you have the ability to customize settings according to your schedule and room temperature preferences. For example, the Bionaire Twin Reversible Airflow Window Fan with Remote Control includes Electronic control with LCD screen, remote control, and Programmable Thermostat.

Cons:

  • A window fan is mounted on a window frame. So you have to let the window open.
  • Window fans require multiple units to cool an entire house.
  • One of the things that makes heat less tolerable is humidity. If you live in a high humidity area and need a system that removes humidity from the air, a window fan may not be for you.

Air Conditioning + Window Fan = A Perfect Match

A window fan is perfect for those who air using an AC.

An AC just circulates the cool air within the room. It cannot bring in fresh air from outside. Using a window fan to complement the air conditioning unit ensures that there is a continuous supply of fresh air in your room. Thus, even while maintaining your AC at a high temperature, you can enjoy great cooling throughout the room.

Another way is to use your air conditioner part of the time and use window fans the rest of the time. Using a window fan as an air conditioner alternative can significantly cut your energy costs.
