Benefits of Installing A High Efficiency AC Unit
Central air is the most common and efficient system used in American homes. These are either a packaged unit or a split system. A packaged unit has the evaporator, condenser, and compressor in one cabinet, usually located on a roof or on a concrete platform nearby. A split system air conditioner has an outdoor metal cabinet containing a condenser and compressor, and an indoor cabinet which houses the evaporator. For homes that already have a furnace but no air conditioner, a split system is the best choice for an air conditioner installation.
High efficiency air conditioners today use 30-50% less energy to cool an area of equal size than those made in the mid 1970’s. Duct sizing, unit location, and insulation are are also important in the cooling effectiveness. Furthermore, the system must match the needs of the home. Too large a unit will do little to remove humidity and too small a unit will not be powerful enough to cool a home on the hottest days.
When considering purchasing a new system for your home look for a model with a high SEER rating (13 or more). SEER stands for Seasonal Energy Efficiency Ratio and most older systems have SEER ratings of 6 or less. Look for the Energy Star label and remember that the higher the SEER rating the lower your overall annual energy bill will be. Professional installation is also key. Improper installation can lead to costing you more.
