A central air conditioning system is an efficient way to ensure consistent and even cooling throughout one's home. However it is also a fairly substantial and costly investment so it is important to make sure one understands how to select the model which will best meet the needs of the household. If they are in the market for new or replacement air conditioning Port St Lucie homeowners should keep these guidelines in mind.
A central air conditioning unit is comprised of distinct parts which work in conjunction with each other to cool the air. The most visible component is the condenser, which is usually located outside the house. There is also an air-handler of which the primary working parts are the blower and evaporator coil, this is often situated in the attic or basement. Refrigeration technology is applied to cool the air, which is released through a network of ducts.
When it comes to buying a central air system, whether for the first time or as a replacement for an outdated one, one must look at its efficiency, size, features, and warranty.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.
The SEER rating of a central air system can be increased by the presence of certain intrinsic features. Dual compressors operated by sensors which regulate the need for more or less cooling, an automatic delay fan switch, variable blower, and larger coils to promote more effective heat transfer are examples of such energy-saving details.
A new A/C should always come with a manufacturer's warranty and it's important for the buyer to carefully read through this before agreeing to the purchase. These can vary considerably from one make to another, and the coverage for some components may be different than for others within the same warranty. Some companies will even offer a "limited lifetime warranty" which is in effect as long as the purchaser lives in the home where the unit was installed.
With the protection of the environment being a primary concern today, most new central air systems use a refrigerant that is less destructive to the ozone layer. Freon has been the dominant refrigerant of choice and it is still used today, however it is also somewhat harmful, so many manufacturers are now offering products which use an environmentally-friendly alternative in its place.
It's also imperative to match the capacity of the air conditioning system with the size of the home it will be installed in. The "size" of an A/C refers to its ability to cool air volume, not the dimensions it possesses. This is measured by tons, or "BTUs" (British Thermal Units). In most cases, 1 ton for every 400 square feet of living area is needed for there to be adequate air flow throughout the home.
