Cooling Offices and Large Homes with Central Air Conditioning
When the weather starts to heat up and the temperatures indoors start to get uncomfortable for working or sleeping, all of a sudden there is a great deal of interest in different solutions for cooling the indoor environment. Many people decide to install central air conditioning for a number of different reasons. The most obvious reason is to provide a convenient way of enjoying nice, cooled air for large homes or for office facilities, when installing individual room air conditioners may not be the best option.
A central air conditioning system does its job by utilizing a “split system,” which is able to condense the air as well as compress it. These systems come with an evaporator that can be connected to other mechanisms that handle air, such as a forced-air furnace. The entire unit is then put together as one complete system and installed exteriorly, usually on the roof of a commercial building or in a mechanical unit outside of a house.
As the central air conditioning begins to work, the cool air is sent throughout the building through a series of ducts that allow airflow into different rooms. The temperature in rooms of a house or different parts of a building is achieved by setting the system controls that come with the unit.
However, there is also the possibility that some centralized air conditioning systems do not come with such controls. In these cases, you will need to purchase the controls for additional cost, and they should be installed at the same time as the entire unit. To avoid surprises during the installation process, it is essential to clarify this with the company that is installing the unit.
Since the noise associated with keeping the home cool is located outside, most homeowners prefer central air conditioning systems. Today, room air conditioners are noisy, and this is especially noticeable if you are trying to sleep. The majority of the noise created by the central air system is handled by locating the equipment outside. Eventhough the air conditioning unit may be working hard to keep the home cool, the interior of the home is nice and quiet.
Central air conditioning tends to be a fairly complex system and the equipment is typically 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. Supply and return ducts are placed throughout the structure to properly circulate the air in a centralized system.
If you are considering installing a new central air conditioner or simply need to replace an existing one, then make sure that the contractors who bid on the job perform a detailed “cooling load calculation” so that the proper system for your home will be installed. Using the “rule of thumb” often results in oversized equipment. A newer unit of the same size shouldn’t just replace the old system. The reason for this is because the existing system may have been the wrong size to begin with, or the home may have had added insulation or more efficient windows put in since the original system was installed.
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.
