Installing Central Air Conditioning – There Are Lots of Choices
If you've been thinking about upgrading your old air conditioner, or installing central air in a house that's had to use natural cooling methods, there's a lot to think about. There are lots of options on the market, and some are more suitable than others. There are even systems for houses that can't be converted to using normal ductwork. Of course, the two biggest things to consider are cooling capacity and air conditioner efficiency. However, don't just go out and buy the most efficient, largest system your budget will accommodate. There's a lot more to installing central air conditioning.
Out of necessity, central air conditioning is a split system. That means that some of the components are inside the house, and others are outside. The parts that shed heat and make a lot of noise (compressor and condensers) are placed outside the house, while the evaporator coil is placed inside. Usually, the evaporator coils are placed inside an existing furnace, so that the blower from that furnace can be used to move cool air as well as warm. Indoor and outdoor parts of a central air conditioning system are joined by lines containing refrigerant and a low voltage cable.
Of course, if your home doesn't use a forced air furnace, the evaporator will need its own dedicated blower to push the air through ductwork. In this case, the blower will probably be installed in a crawlspace or in the attic, and connected to an insulated, flexible ductwork. This is the cheapest and easiest to install in old homes that weren't built for air conditioning. If there's no way to install ductwork at all, you can even get ductless systems, which have been popular for years in Asia and Europe, and are becoming more popular in the US than before. In this type of system, a single outdoor compressor can sever a number of different indoor units, each of which has its own fan and evaporator coils. The boxes are unobtrusive, but can be large.
When installing central air conditioning in your home, choosing the right type of unit is important. It's the first step to getting an economical, efficient unit that will offer a comfortable environment. Ask your local heating and cooling technician about the options that are most suited to your home, or check online for more information about specifically types of central air conditioning installation. There are lots of great sites out there, offering plenty of useful information. You may be surprised by how many options you have.
