How do you find a good central air conditioning system? The way that central air conditioners are rated is according to their seasonal energy efficient ratio (SEER). The seer is a calculation of the cooling output divided by the power input, which brings up an approximate climate average. Therefore, the higher the seer the better the central air conditioner you will be getting.

What is a good seer number to base on? Many older air conditioners are going to have a number around six or seven. However, new standards that will be in effect in 2006 will set the seer requirement at 13, which is an improvement of 30% from what it currently is at 10.

What a central air conditioner is doing is cooling and dehumidifying the air. What the system uses to accomplish this is a condenser, evaporator coil, and refrigerant piping to operate. The central air conditioner has a couple different kinds of units, a split system and a packaged central air conditioner.

A split system has an actual split system, meaning there is a separation between the condenser and evaporator. The condenser and compressor are in a cabinet outside the house, as the evaporator is in its own cabinet inside. As hot air is removed and transported to an evaporator coil as a warm liquid, the expansion of the liquid causes it to cool, thus cooling the air. If your home has a furnace but no air conditioner, then this is the way to go.

Another type of central air conditioning unit is a packaged central air conditioner. With this system, the condenser, compressor, and evaporator are all in one cabinet placed on the roof or next to the house. This kind of air conditioner often includes electric heating coils or a natural gas furnace. This type of unit eliminates the need for a separate furnace indoors as the air conditioner and central heater are combined.

The price of getting a central air conditioning unit varies like everything in life from company to company. Some of the determining factors include whether you’re getting a 2 Ton system through 5 Ton system, if you need the compressor installed on your roof, and where you live. A base price for a 2 Ton system without it being installed on the roof is going to run around $2700. A good site to check out prices for a central air conditioner is listed below:

If you are replacing an air conditioner, you’re going to have to match the size of the previous one to make sure the unit is not to big and not too small. To get more quotes to find the best air conditioner for you, check out the site below:
