A window air conditioner is perfect for that person who does not want the expense of purchasing a central air conditioning unit.  A window air conditioner gives you a place to go when the days are steaming hot and you just need a place to go to cool down.  A window air conditioner is generally used to cool down a room or two.  It is not generally used to cool down an entire home.

A window air conditioner comes in different sizes that cool different capacities.  It is important to find the window air conditioner that will be energy efficient for your home, as well as be effective at cooling down the room.

Choosing the Wrong Window Air Conditioner can Cost you

It may seem that buying a larger window air conditioner will cool the room better; however, if you purchase a window air conditioner that is too large for a room, then it will turn on and shut off too many times.  This will automatically cost you more in energy, and it will not dehumidify the room correctly.  However, if you buy a window air conditioner that is too small, it will run too much, again wasting energy and it will not be effective at cooling down the room.

Choosing the Right Window Air Conditioner that will be Effective for your Home

Choosing the right size or cooling capacity window air conditioner for home is essential.  To determine what size cooling capacity is necessary for the room you want to cool down, you will start by measuring the length, width, and height of the room you want to put the window air conditioner in. Then multiply in this order:  length times width times height.  This is the volume of the room.

Next, you will need to determine which wall is exposed to the outside elements.  Determine if this wall is east, west, north, or south.  Each direction will be given a value.  East has a value of 17.  West has a value of 20.  North has a value of 16.  South has a value of 18.  At this point, take the volume of the room and multiply by the corresponding number you have assigned to the exposed wall.

Next, take the number you have just come up with for the exposed wall and divide it by your home’s level of insulation.  For a home with poor insulation, divide by 4.  For a home with good insulation, divide by 5.  For a home with excellent insulation, divide by 6.  This calculation will give you the number of BTU’s that are necessary for the new window air conditioner.

This calculation is important as it takes into consideration your individual home’s needs.  It will provide you the most accurate cooling capacity for your home.  The result of these calculations will give you the approximate number of BTU's your new air conditioner will need to have.

Choose from the Many Different Styles

Buying a window air conditioner does not mean you have a big ugly “thing” sticking out of your window.  These days, you will be surprised at all the different stylish window air conditioning units you can choose from.   A window air conditioner unit comes in lighter tones with edges that are rounder.  You are sure to find a window air conditioner that will fit in with your décor.

A window air conditioner can be an excellent addition to your home.  As long as you purchase a window air conditioner that is the right cooling capacity for your home, you will be set this summer.
