Although window air conditioning units can come in handy, they can also cause excessively high electric bills and are also very inefficient. You end up wasting a lot of that air conditioning by opening and closing the door to the room that the unit cools, and it has to work harder and use a lot more energy. Beyond all of that, window units have the major drawback of only cooling a single room at a time; who wants to spend all of their time in one room of their house on a hot summer day? Central air conditioning systems are definitely the way to go if you want a pleasant, climate controlled house.

How Do Central Air Conditioning Systems Work?

Central air conditioning systems are comprised of indoor and outdoor components. The loud, annoying components - like the condenser coil and the compressor - are kept outdoors where they won't bother or disturb you. These parts are also kept outside because they emit a lot of heat, which would obviously counteract the effects of cooling your home to begin with. The evaporator coil segment of most central air conditioning systems is kept indoors, usually within a section of the home's forced air furnace. These systems typically work by pulling warm air from the house - and sending out cool air - via the home's existing duct work.

How Much Do Central Air Conditioning Systems Cost?

The cost of having central air conditioning systems installed depends on a couple of factors; the size of the house and whether or not it already has duct work are the two biggest ones. For example, a 2,000 square foot home that already has duct work throughout will be compatible with central air conditioning systems that cost approximately $3,500 to $4,000. A house of equal size - but without existing duct work (meaning it has to be installed) - will be compatible with central air conditioning systems that cost around $7,000 to $8,000. Sometimes, central air conditioning systems can cost even more than that, depending on the specifics of the home in question.

Shopping For Central Air Conditioning Systems

Since the price of having central air conditioning systems installed can vary so considerably, it is critical to shop around for as many quotes as possible. You are bound to be surprised by the many divergent quotes you end up receiving for central air conditioning systems for your home. These variations are common, and are usually due to what an individual contractor is willing to do and how experienced he is with your type of home. After collecting your quotes, look them over carefully and determine whether or not it makes sense to have central air conditioning systems installed in your home; if you decide it is, get the ball rolling by hiring the contractor of your choice.
