How to Choose an Air Conditioner

Posted by Wattson on May 29, 2012

People who are in the market for a home air-conditioning unit may believe that the size of the unit does not matter and end up getting the wrong size for their room. However, buying a unit that is too large or too small for a room often causes problems such as dampness or excessive wear on the unit. When you are looking for an air-conditioning unit, there are a few factors you should consider.

Buying an air conditioner of the correct size is vital to proper cooling. Before you purchase an air-conditioning unit, you need to determine the size required by the room in which you will place it. A unit that is too large will waste energy. A unit that is too small will not cool the room completely. Once you figure out the square footage of the room, you can determine what size unit you need by figuring out how many BTUs per hour will properly cool your room. For example, if the room is 300 to 350 square feet, you need a unit that has a cooling capacity of 8,000 BTUs per hour.

Another factor you need to consider when purchasing an air-conditioning unit is the type of unit you need. A portable air conditioner is a wheeled unit that can be moved to different rooms. Typically, these units provide a modest amount of cooling.
A window unit is designed to fit in a window. With this type of unit, you may have to measure the window to ensure a proper fit. Window units must be securely placed in the window with no space between the frame and the air conditioner. Some air conditioning units can be installed in a wall, which is ideal for rooms without windows. You will need to hire a professional to install a wall air conditioner.
Before you purchase a new home air conditioning unit, know exactly what type of unit you want. This will make finding the right one much easier.
