Energy Ratings of Reverse Cycle Ducted Systems

Reverse cycle ducted systems distribute air through concealed ducts and are designed to operate for entire homes or large sections of homes.They tend to have an energy rating that accounts for the efficiency of heat production per unit of electricity consumed.
Generally, the more stars on the energy rating label, the more energy-efficient the unit is, which translates to lower energy bills for you.

Energy Ratings of Split Systems

Split systems consist of two units: an indoor unit and an outdoor compressor. These systems usually service a single room or a defined space.
The energy efficiency of split systems can vary greatly, with some models offering high-energy star ratings, resulting in significant savings on your energy bills.
Split systems are assessed on their energy performance in both heating and cooling modes, and these ratings are displayed on the product’s energy rating label for you to review before purchasing.

Installation Considerations

Before deciding on an air conditioning system, you need to understand the different installation requirements for ducted and split systems. Each has its unique process and considerations that will affect your choice.

Installation Requirements for Ducted Systems

Ducted systems require a more extensive setup process due to their complexity.
Your home needs adequate space above the ceiling or beneath the floor to accommodate the ductwork.
It’s essential to have a detailed assessment done by a professional to ensure your home’s structure can support ducted air conditioning.
They will check for sufficient space, assess the load-bearing capacity of walls or roofs, and determine the layout of the ducts to ensure efficient airflow.
Keep in mind that ductwork installation can be quite invasive, necessitating ceiling or floor access and potentially lengthy installation times.

Installation Requirements for Split Systems

In contrast, split systems are less invasive to install and generally quicker to set up.You will need a suitable location on both the interior and exterior walls of your home.
The outdoor unit requires ample space around it for proper airflow and should be placed away from direct sunlight if possible.
On the inside, the wall-mounted unit should be installed high on the wall to ensure optimal air distribution.
Installation often includes running a conduit through a small hole in the wall to connect the indoor and outdoor units. It’s also less disruptive, as most installations can be completed within a day.
