Summer is almost upon us. Days at the beach, filled with fun and laughter, vacations to far away places, lounging around by the pool, and enjoying outdoor activities with friends. However, what is also around the corner, is the threat of hot, humid and muggy summer weather.


Such weather can simply take the breath from you, making you tired, feeling run down and tired. Trying to get a good nights sleep during a wet, hot night will most certainly not give you a well rested feeling for the coming day.

While you might not want to pay for central air, you still want to be cool. The answer is simple: A window mount air conditioner.

How to Choose a Window Mount Air Conditioner:

The Right Size

Air conditioners are specifically designed to cool (or warm) a living space of a certain size, so take advantage of the square footage of the living space, and match it to the proper size. if you are not sure of the size of your room, simply take a tape measure and measure two adjacent walls. If one wall is 10 feet, and the other 9 feet:

9 x 10 = 90 square feet

This means your room is 90 square feet. Next, choose an air conditioner which has the BTU’s to match your square footage. For instance, a room of 90 square feet will require a small air conditioner.


Small air conditioners are those which have 5000 to 6500 BTUs, and cool a living area up to 300 square feet. You’ll find that these are small, light and compact models, and usually the most affordable. However, please note that they will not be able to cool a room larger than 300 square feet.


Medium sized air conditioners can handle rooms up to 400 square feet and run 7000 to 8200 BTU’s an hour. Slightly more in price, larger and heavier than the smaller air conditioners.


Large Air conditioners usually can handle a closed off area up to 650 square feet, and their BTU’s range from 9800 to 12500 an hour. These are the largest and heaviest air conditioners, so their installation will be more difficult than the small or medium sized.

The Noise Factor

Summer nights can get pretty steamy sometimes, so it’s automatically understood that you’ll be running your air conditioner at night. In order to get a good nights sleep, it is necessary to check the decibel level in the specifications. Decibel levels are noted as dB. So an air conditioner which has a decibel noise level of 55 on the high setting, will be written like this: 55 dB.

The Style of Window

All of the air conditioners on our list are window mounts. This means they they are designed to be installed in a window. Before you purchase, it’s necessary to look at the type of windows you have in the room you want to cool. Standard windows are those that open and close up and down. Slider windows are those that slide to the side to open. Casement windows are those that swing out when open. If you have a casement window, know that most installation kits will not work. So, if this is the case, you’ll have to create your own, DIY installation kit.

Smart Features

Todays air conditioning units are often packed with modern features, such as an integrated 24 hour timer, LED digital displays, convenient remote controls, air filter alert indicators, touchpad controls that allow you to easily set the mode, timer, fan speed and power.

Energy Efficiency

This is another factor for you to consider. There are a few ways you can judge if the model you are interested in is energy efficient for you. First, check the specifications and look for the letters, ‘EER’, this refers to Energy Efficiency Rating. The nigher the number, the more energy efficient that unit is. In the specs, it will look like this: EER 11.1. Another indicator is if the unit is Energy Star certified. This means that the air conditioner will use 10 percent less energy than other units of its class.

Heating Ability

Some window mount air conditioners are designed to be used year round, cooling in the summer and warming in the winter. These are known as hot and cold air conditioners. During the winter months, these multi-purpose air conditioners produce and energy efficient heating option.
