Efficiently Cool Your Home With A Central Air Conditioning System

Each year as the temperatures of summer climb, there is a flurry of activity as people scurry around to find ways to help make their lives more comfortable with air conditioning. And, each year more and more people are turning to central air conditioning to control the environment in their homes and their offices. These large centralized units provide the best combination of convenience and efficient cooling, especially for spaces that are just too large for room air conditioners to be effective.

A centralized air conditioning system does its job by utilizing a "split system," which is able to condense the air as well as compress it. Forced-air furnaces are one of the mechanisms that handle air, and the evaporator that comes with these systems can be connected to it. Once the whole unit is assembled it is installed outside, either on the roof of a commercial building, or a unit outside of a home.

When central air conditioning begins functioning, the cooled air is blown through the edifice by fans via the ductwork that has been installed, allowing the air to flow to the different areas in the building. The temperatures are controlled either with the use of a central control unit, several units to control different zones, or individual control units that are placed in each room.

There is the possibility that some centralized air conditioning systems do not come equipped with these controls. In these instances, the controls must be purchased at an additional cost and should be installed at the same time as the complete unit. It is important to clarify this upfront with company that is selling and installing the unit so that there are no surprises during the installation process.

Since the noise associated with keeping the home cool is located outside, most homeowners prefer centralized air conditioning systems. Even the newer room air conditioners can be rather noisy, especially when running at night in bedrooms. To handle the noise associated with central air systems, the equipment is located outside the home. Although the air conditioning unit is hard at work, the interior of the home is quiet and cool.

Central air conditioning systems are rather complex and are usually installed when a building is under construction. To have a comfortable and healthy environment in a home or office, these heating and air conditioning systems supply the air filters and purifiers as well as heating and cooling. A centralized system utilizes supply and return ducts that are placed throughout the structure in order to properly circulate air.

Make sure that the contractors bidding on your new air conditioning system make a detailed "cooling load calculation" to insure the proper system is installed. To avoid having oversized equipment, use something besides the "rule of thumb". A newer unit of the same size shouldn't just replace the old system. The home may have become more efficient over the years, with the addition of insulation or energy efficient windows and that can be the reason for this issue.

All of the air conditioning manufacturers must have the equipment they produce rated for efficiency, according to the law. The rating for a central air conditioning unit is called the Seasonal Energy Efficiency Rating, or SEER. Heat pumps carry an HSPF, or Heating Seasonal Performance Factor, rating. The higher the number of the SEER/HSPF rating, the more efficiently the equipment uses electricity.
