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.
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.
There are many points to take into consideration when searching for the ideal A/C system including size, features, efficiency, and product warranty. In particular, its efficiency is of interest to most buyers since it can run up a hydro bill quite a bit if the unit does not operate in a manner that provides optimal cooling for each dollar spent.
Every model of air conditioner comes equipped with a SEER - "Seasonal Energy Efficiency Rating" label which provides consumers with information about the unit's efficiency. The higher the number, the better the efficiency of the A/C and the less money it will cost to run. Those with the highest efficiency levels usually have ratings between 15 and 17, but anything over and including 13 is reasonable.
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.
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.
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.
