Central air conditioning is a unit that normally uses ducts to distribute cool air to several rooms in a home or building. With central air con, the moment the handling unit is turned on it begins to draw in the warm air from various parts of the building. The warm air is then cooled and passed through the return ducts back into the building. During this process dust and lint is filtered out of the drawn in air and in some central air conditioners special filters also filter out other contaminants as well.
Types of central air conditioning
There are basically two types of central air conditioning: the package system and the split system.
In the package system the entire air conditioner is housed in one unit that generally sits on the roof of the building or on a concrete slap near the building. Package air conditioners usually have electric heating coils or their own natural gas furnace. If your package air conditioner has its own furnace, no other furnace is needed to warm the building during the winter.
A split system central air conditioner is split into two parts: the outdoor section is a metal cabinet that houses the condenser and the compressor while the inside unit houses the evaporator and sometimes a furnace or a heating coil.
Benefits of central air conditioning
- They cool a larger area and the furnace can be used for heating as well as cooling.
- They are out of the way, not sitting glaringly in a window or poking through a wall where they draw attention.
- Central air conditioning is usually quiet since all the parts that make noise are conveniently located out of doors.
Other considerations for central air conditioning
If you are considering changing to central air conditioning, the first and most important consideration is whether or not you have suitable duct work for use with a newer, more energy efficient central air conditioner. If you do not have duct work, or if your duct work is old and cannot be used with the central air conditioner you are thinking of installing, you might be wiser to choose a mini split air conditioner as it has many of the benefits of a central air conditioner without the need for ducts to transport the air flow.
If you are building a newer home and want to include duct work for your central air conditioner or central heat and air then this should cause few problems. However, older homes often have limited space to fit duct work properly without a lot of upheaval. It is simply more cost effective to find a different way of cooling older homes than central air conditioning.
Seeking the advice of an air conditioning professional is your best bet if you are not sure whether your home is capable of supporting the necessary duct work for central air conditioning. There are many experts that will not only give you their advice, but will help you to find the best air conditioning unit for your home too.
