No matter which type of split air conditioning unit is chosen
, it is important to make sure you are choosing a unit that is capable of handling the needs of your home. For those who need replacement units, if the other unit worked adequately, buying one of similar capacity is all you need to do. There are also online calculators to help homeowners choose the right unit. Units that are too powerful will cut on and off too much, thus possibly leading to humidity problems. Units not powerful enough will always be on, and run the risk of burning out, or at least using more electricity than they need to.
