What’s Split AC?

Split air conditioning units have two components, one inside and one outside. Mini split units don’t use ducting and can cool single or multiple rooms. The outdoor compressor cools the air, while the indoor fan distributes it. Mini split systems require drilling through an exterior wall but are easier to install than traditional split units. It’s important to choose a unit that can handle the needs of your home. Overpowered units cause humidity problems, while underpowered units use more electricity than necessary.

A split air conditioning unit is one that has two major components separate from each other, one inside the building and one outside. A central air conditioning unit is almost always a split unit. There are also air conditioning units called mini split air conditioners. These units work very similarly, but don’t use ducting to send the air. These can provide air conditioning for a single room or cooling for multiple rooms and are often called ductless air conditioning units.

The two main components of a split air conditioning system have different functions. The unit located outside, called a compressor, cools the air and manages the condensate. This saves you the trouble of having to find a way to drain the water created by the air conditioning process indoors. The indoor unit, called a fan, is responsible for distributing the air to the rest of the house. This is done through a forced air system, usually using a fan and a series of ducts that distribute the fresh air to every room in the house with a vent. An air vent will return air to the unit.

For those who live in homes without ducts, or who feel they don’t need to cool every room, a mini split air conditioning system may be an option. This is much easier than trying to install duct work for a traditional split air conditioner. No need to worry about running ductwork or substantially cutting through walls. These units tend to work more efficiently than window air conditioners, but they cost more to begin with.

A miniature system works by installing an air-handling piece in the room you choose. Two lines are then connected to an external unit. While this will require drilling through an exterior wall, it will not require the cutting required for ducted air conditioning units. One line will supply coolant to the internal component. The other line will eliminate the condensation. For those who need to cool several rooms, it is possible to install several internal components on an external component.

Regardless of which type of split air conditioner you choose, it’s important to make sure you choose a unit that can handle the needs of your home. For those needing replacement drives, if the other drive performed adequately, simply purchase one of similar capacity. There are also calculators online to help homeowners choose the right unit. Overpowered units turn on and off too much, thus causing humidity problems. Units that aren’t powerful enough will always be on and run the risk of running out of power or at least using more electricity than necessary.
