Central AC Systems are used to cool and heat all rooms in a property at one or more set Temperatures.

A common configuration consists of an outside unit called a condenser and an inside unit called an air handler or furnace. This type of system is also called a split system.

These types of systems vary in efficiency. They are measured by their SEER rating. (seasonal energy efficiency ratio). The higher the number the higher the efficiency or the more you save on your electric bill. The lowest rating as of 2015 is a 14 SEER. The highest as of this writing is a 23 SEER. Also, the higher the rating the more expensive the equipment will be to purchase.

The good news is that if your power company is FPL you can get a great rebate by purchasing AC equipment above the minimum rating. The higher the rating the higher the rebate.

Of course, there are other types of central AC systems depending on the application. There are also many manufacturers of these types of systems. Some claim to be better than others of course. The main components of all central AC systems are the same.

Before deciding on what type, manufacturer, and efficiency rating are right for you, consult with a professional to be sure your needs are going to be met. Most homeowners do not know how to make this decision without expert advice. It’s a major expense.
