Reasons to Install Split System Air Conditioning in Your Home

You may be considering establishing air conditioning and be weighing up the options. One possibility is a split system unit. Consider the following reasons to undertake a split system installation project in your home.

Can Heat Different Size Areas 

You can configure a split system variously, to heat one room or several, depending on your needs. A single arrangement consists of one indoor and outdoor unit. A multi-zone split system, however, consists of several indoor components, connecting to one outdoor element. Thus, you can be selective about which rooms to install the air conditioning in. You could locate them in living areas and bedrooms, and not concentrate on less-occupied areas of the home, or you could install a single unit in an open-plan space. The choice is up to you.

Easy Installation

With a split system air conditioner, the components are split between inside and outside — the compressor and condenser units are outside, and the evaporator is inside. A refrigerant-filled coil runs between all the components, absorbing the heat from the rooms and releasing it outdoors. The coils and tubes that connect all the elements are relatively narrow and can be passed through a small hole in the wall. Thus, the installation doesn't require major construction work in the home.

Conversely, ducted air conditioning involves an extensive installation process. A duct network is set up within the roof cavity to transport the cooled air to the room vents. Because the ducts move the air around, they need to be relatively wide and large, and they need to travel to every room in the home that will be air-conditioned. This contrasts with the narrow coils that connect the indoor and outdoor components of a split system — these move refrigerant, not air.

Operates Efficiently

Split system air conditioners work efficiently by absorbing a room's heat and releasing it via the outdoor unit. The refrigerant-filled coils are central to the process. The indoor unit pulls air over the cold coils, and the coldness transfers from the refrigerant to the air, which blows back into the room. The warm refrigerant then travels through the coils to the external component and discharges the absorbed heat into the air. Using the refrigerant to remove the heat is effective as it doesn't use unnecessary energy.

Conversely, the ducts in ducted airconditioning can be inefficient. As the cold air flows through the channels towards the vents, it loses some coldness through leaks in the ducts and through the duct walls. Thus, these systems waste a degree of energy, as they produce cold air that gets wasted.
