Ductless Split AC Systems
Ductless Split AC Systems vs Central Air Units
Ductless Split AC Systems have three advantages over other systems.
With several indoor blower units, you can essentially create a zoned cooling system. Each indoor unit can operate independently of the others, so seldom-used rooms don’t have to be cooled until they’re needed. If one room requires extra cooling at a specific time of day, that blower can cool independently from the rest of the building. When all rooms are occupied, setting the thermostat to the same temperature on all the units eliminates changes in temperature when leaving one area to enter another. You set the controls for maximum comfort and efficiency.
When normal central air comes on, there’s usually an announcement by way of rattling ducts. Since ductless split AC units have none, the only announcement is the gentle delivery of cool air through the blowers. In addition, the outside unit can be located up to 50 feet away, reducing the outside compressor noise associated with central air units.
As technology has advanced, Seasonal Energy Efficiency Ratio (SEER) ratings have increased. Ductless split AC units are no exception. The law now requires a minimum rating of 13. These split units are quite efficient, with ratings in the mid-20s or higher. The higher the rating, the less electricity the equipment requires. An extra advantage is that air traveling through a network of ducts can lose as much as 40% of its cooling before reaching the indoor area. Since ductless split AC units emit air directly from the inside blower or air handler, there’s no degradation of temperature and, therefore, no loss of cool air.
