Split System Placement in Perth: Where to Put the Units
Split system placement, where the indoor and outdoor units go, has a big effect on how well the system cools and how comfortable it feels. Good split system placement makes the difference between even, quiet comfort and hot spots or drafts. Here is how to get it right in your Perth home.
Why placement matters
Split system placement affects airflow, comfort, efficiency and noise. An indoor unit in the wrong spot can blow straight onto a bed or desk, or fail to reach the far side of the room. Getting the placement right means the cool air is distributed evenly, so the whole room is comfortable, not just part of it.
6 tips for split system placement
- Mount the indoor unit high on a wall
- Aim airflow across the room, not onto beds or desks
- Avoid placing it above doors or windows
- Keep the outdoor unit shaded and ventilated
- Site the outdoor unit away from bedroom windows
- Keep the pipe run between units reasonably short
The indoor unit
Good split system placement puts the indoor unit high on a wall, where it can push air across the whole room. It should not blow directly onto where you sit or sleep, and it needs clear space around it. An installer chooses a spot that distributes air evenly and suits the room’s shape and use.
The outdoor unit
Split system placement of the outdoor unit matters too. It needs good airflow and is best shaded from the harsh afternoon sun, which helps it run efficiently. It should sit on a stable base with space around it, and ideally away from bedroom windows and neighbours, since it makes some noise when running.
Keeping the pipe run short
The distance between the indoor and outdoor units, the pipe run, is part of split system placement. A shorter, more direct run is more efficient and often cheaper to install. Where the units have to be far apart, the system is sized and installed to suit, but a sensible layout helps performance.
Sun, shade and efficiency
Sun exposure affects both units. A shaded outdoor unit works less hard, and an indoor unit in a room with big, sunny windows has more heat to fight. Good split system placement takes the sun into account, on both the outdoor unit and the room, to keep the system efficient in Perth’s climate.
Getting it assessed
The best split system placement comes from an installer assessing the room, the wall, the outdoor space and how you use the room. They balance airflow, efficiency, noise and looks to choose the right spots. A little thought here means better comfort and lower running costs for years.
Looks and the room
Placement is partly about looks, too. The indoor unit is visible, so it should sit where it works well and does not dominate the room. A good installer balances the best spot for airflow with a sensible position for the look of the space, so it performs without being an eyesore.
Drainage and pipework
The indoor unit produces condensation that must drain away, so placement considers the drainage route as well as the pipe run. Getting the drainage right avoids leaks and damp. An installer plans the pipework and drain so everything runs neatly and reliably behind the scenes.
Why use a licensed installer
Getting split system placement and installation right is skilled work spanning refrigeration and electrical trades. A licensed installer positions and installs the units correctly and safely. The state’s Building and Energy sets the electrical standards involved.
