Split System Air Conditioning

The high wall split system air conditioner would be the most popular air conditioner on the market.  The reason it is called a split system is because the indoor and outdoor unit are split by interconnecting pipe work.

This particular type of air conditioner is only designed to do single zones or rooms. For example if you were to install the indoor unit in the living area you will still receive some heating or cooling into the other directly joining areas but not to the comfort that you will have in the living area were the indoor unit is installed.


The split system air conditioner ranges in size from 2.5KW that is suitable for a bedroom right through to the largest at 8KW for a large living area. If you would like to calculate the size of the system required for you home please select the Quick Size Calculator or Advanced Size Calculator from the menu or contact Monaro Air Canberra that can organise a Technician to give a free site inspection and quote.


The split system air conditioner on heating is approximately 70% cheaper to run than electric heating and 50% cheaper to run than Natural Gas heating and uses less electricity to run on cooling.
