Click here to see why reverse cycle air conditioning is the most cost effective method of heating your home this winter.
what is a split system?
A split system air conditioner consists of an indoor unit and an outdoor unit. The outdoor unit is installed in an unobtrusive location to minimise noise and maintain the aesthetic of your home.
Enjoy the quiet convenience of these room air conditioners without the bulky ductwork or window unit fitting.
Our fully qualified refrigeration technicians will provide the most ideal and cost effective placement of your split system.

The gas (refrigerant) is fed into the condenser and pressurised, causing heat in the gas to rise. The pressurised gas then travels through the pipework which condenses it into a liquid. The pressurised liquid then further travels through the tubing to an expansion joint.
Here, there is a rapid reduction in pressure and the liquid becomes a gas again, and a large amount of heat is released resulting in it becoming much cooler. The gas then travels back to the condenser and the process is repeated.
The room air is drawn into the unit and passes over the evaporator coils which cools the air significantly and blows the air back into the room. The air continues to circulate through the system until the set temperature is reached and the apparatus then automatically shuts off.
how does a split system air conditioner work?
what is a standard 'back to back' installation
A ‘back to back’ installation is where the:
-
Indoor head unit is located on an external wall (a wall that has the outside of the house on the other side), and;
-
The outdoor condenser unit is placed directly behind the indoorhead unit at ground level.
When standing in front of the indoor head unit the pipework exits from the bottom right hand side and similarly when looking at the outdoor unit from outside the pipework connection is also located on the right hand side, that is why you see it offset in Pic 1.
What's included in a standard back to back installation?
-
Based on a standard brick and tile, single story domestic residential house;
-
10 metres of mains cable connected to a local circuit if 2.8kW and below (except Fujitsu) or;
-
10 metres of mains cable connected direct to mains distribution board (2.9kW and above) plus;
-
3 metres of interconnected pipework and cables;
-
Indoor head unit is mounted no more than 2.4 metres high (top of unit);
-
The outdoor condenser unit is placed ‘back to back’ to the head unit at ground level;
-
1 x 2 metre length of PVC capping (to enclose all pipework and cables) and the;
-
Travel charges may apply;
-
See attached full terms and conditions.
Different Types of Installations
Hover your mouse over the images below for explanations of different types of installations.
LEFT OR RIGHT HAND DISCHARGE
When the indoor head unit is mounted on an internal
wall in the corner adjacent to an external wall with the pipework coming out the left or right hand side.
WALL BRACKET
Anti vibrational bracket designed especially for air conditioning.
ROOF BRACKET
Anti vibrational bracket designed especially for air conditioning.
MOUNTED ABOVE A WINDOW
Can normally be done if you have a clearance between
the top of the window and the ceiling of 600mm.
UP & OVER
The head unit is on an external or internal wall and the condenser unit is located in another part of the house (therefore not a ‘back to back’ installation).
