Central air conditioners use a method of structural cooling in which a centralized unit cools and dehumidifies air before circulating it throughout a building. Central air, as it is also known, is often bundled with a heating system, as they both rely on similar amounts of electrical power and ductwork to distribute cooled or heated air. The air conditioner will also vent to the outdoors to remove excess heat and moisture. Homes in hot climates benefit from central air because it eliminates the need for wall or window units that can be an eyesore and can be difficult to manage.
Facts about Central Air Conditioners
AC units are composed of three major parts. The compressor, a condenser and an evaporator. These parts work together to transfer heat form the air inside of your home to outside air with the use of chemicals. AC units typically last for 10-20 years. If you have started making too many repairs it may be a bad sign. If areas of your home aren’t cooling properly or if your unit shuts on and off or runs excessively you may need to replace your unit. If you’re seeing that your utility bills are continuing to rise this as also a telltale sign that your unit is not preforming as it should. Homeowners can expect to pay anywhere from $500 to $4000 for a new central air conditioning unit. The cost will also depend on individual homes and any additional ductwork necessary and the type of unit installed.
Installation of Central Air Conditioning Systems
A professional air conditioning contractor will properly size a new unit for your home. Your entire home will need to be measured and analyzed to get all the R-values, window types, orientation, infiltration rates, and possible duct leakages which will determine the load calculation. A load calculation determines the amount of heat energy that needs to be removed from a space to cool it. With central air, the main unit is usually placed outside or in an isolated area because it becomes noisy when the refrigeration cycles the cool air and extracts humidity. The unit connects to ductwork that runs through your home using blowers to push the cool air out of the ducts and the cool the rooms down. Getting a unit that is Energy Star rated means the added saving of money in the future by having lower utility bills and they are better for the environment. These units are also built for durability and longevity.
