People who desire even cooling in all the rooms of their home should invest in a central air system. This can be a rather costly investment, so before deciding on a particular model of central air conditioning Port St Lucie customers need to have a good understanding of what they should look for in such a system.
The design of a central air cooling system consists of several components that work together, including a air condenser, which can normally been seen outside the house, an air-handler with an evaporator coil and blower that it usually found in the home's basement or attic, and a series of ducts that allow for air exchange in every room. The air is cooled using refrigeration technology.
When it comes to buying a central air system, whether for the first time or as a replacement for an outdated one, one must look at its efficiency, size, features, and warranty. Hydroelectricity is used to power an A/C unit, so it is paramount to select one that provides maximum cooling for every dollar spent on energy.
The efficiency of an A/C is indicated on the label affixed to it and is denoted as a "SEER" rating, this stands for "Seasonal Energy Efficiency Rating". Higher numbers are preferred, with most newer models having ratings between 15 and 17, although 13 and higher is generally considered efficient.
There are particular features built into a central air system which increase its efficiency or SEER rating. Large coils provide better transfer of heat, and a variable blower and automatic delay fan switch also maximize the use of energy for cooling. Dual compressors with sensors indicating when more or less cooling is needed are another energy-wise addition to some system designs.
New air conditioning units should come with a warranty from the manufacturer which guarantees their parts will last for a specified time period. The length of time covered, and parts included under the warranty can vary from one manufacturer to another, and it's important for the purchaser to read through these carefully before making a decision. In some cases, there may be a "limited lifetime warranty" assuring the A/C for the entire time the customer lives in the house.
Many of the central air units today are moving towards the use of refrigerants which are not harmful to the ozone layer. When leaks develop in A/C units, these gases are released into the environment. CFC's were the most damaging, and as a result they were banned in the 1990's. Freon is still in use, but it does have some destructive potential so alternatives which are more eco-friendly continue to be developed as possible replacements for this refrigerant.
The size of the air conditioning system is another important aspect one must determine. It must possess the necessary capacity to ensure even air distribution throughout the home. A/Cs are measured in tons or BTUs (British Thermal Units) by the ability it has to cool down air, the physical dimensions don't matter. In order to have sufficient air flow, 1 ton per 400 square feet of space is recommended.
