So, you’ve decided to upgrade your home comfort with a brand-new split system aircon. Fantastic choice! These units are champions at keeping your Victorian home wonderfully cool in summer and cosy warm in winter. But here’s a little secret many homeowners overlook: simply buying the best unit isn’t enough. The real magic, the true path to ultimate comfort and significant energy savings, lies in where your split system is installed.
Imagine having a powerful engine, but placing it where it can’t breathe. That’s what happens when a split system isn’t optimally positioned. At Plum Heating and Cooling, we believe in helping you unlock the full potential of your investment. Let’s pull back the curtain on why placement is so critical and what you need to know to get it right.
The Indoor Unit: Your Comfort Command Centre
The indoor unit is where the magic happens – it’s responsible for circulating that perfectly conditioned air throughout your living space. Its placement isn’t just about aesthetics; it’s about physics!
- Height Matters, A Lot: Picture this: cool air naturally sinks. So, where’s the ideal spot for your indoor unit? High up on the wall, typically around 2.2 metres from the floor (or about 15cm from the ceiling). This allows the cold air to fall and spread evenly, creating a consistent temperature throughout the room. If it’s too low, you’ll feel pockets of cold air while other areas remain warm, forcing your unit to work harder.
- Central Location is Key: Think of your indoor unit as the heart of your comfort system. For optimal air distribution, installing it in a central part of the room, or even in the largest area of the space you want to cool, ensures that conditioned air reaches every corner efficiently. Avoid placing it in a narrow hallway or tucked away where airflow is restricted.
- Avoid Obstacles and Direct Sunlight: Walls, large furniture, curtains, or even that towering bookshelf can act as barriers, blocking the free flow of air. Ensure the unit has clear space around it for optimal performance. Also, direct sunlight hitting the indoor unit can trick its thermostat into thinking the room is warmer than it actually is, leading to unnecessary over-cooling and wasted energy.
- Steer Clear of Heat Sources: Just like direct sunlight, placing your unit near other heat-emitting appliances (like a television, fridge, or even a lamp) can confuse its sensors. The unit might work overtime trying to cool down what it perceives as an overly warm spot, leading to inefficiency.
The Outdoor Unit: The Workhorse’s Best Spot
While often out of sight, the outdoor unit is the powerhouse of your split system, responsible for expelling heat (or drawing it in for heating). Its environment directly impacts its efficiency and lifespan.
- A Stable, Level Foundation: The outdoor unit is heavy and vibrates during operation. It needs to be placed on a firm, level surface, such as a concrete slab or sturdy mounting brackets. An unstable base can lead to excessive noise, wear and tear, and reduced efficiency over time.
- Unrestricted Airflow is Paramount: Just like the indoor unit, the outdoor unit needs to breathe. It circulates a lot of air. Ensure it has at least 30-50cm of clear space around its sides and back, and about 1 metre above it. Avoid placing it in enclosed spaces or directly against dense foliage, which can trap heat and restrict airflow, making the unit work harder.
- Mind the Noise (for Neighbours and Yourself): While modern units are quieter, they still produce some operational noise. Consider placing the outdoor unit away from bedrooms, quiet zones, or your neighbour’s windows to maintain peace.
- Protection from Elements (Without Hindering Airflow): While built to withstand the elements, some protection from direct, harsh sunlight (which can reduce efficiency) or heavy rain can prolong its life. However, never cover it in a way that restricts airflow. A strategically placed awning or a breathable cover designed for aircon units can offer benefits without compromising performance.
Connecting the Dots: The Vital Links
The pipes and electrical wiring connecting your indoor and outdoor units also play a role in efficiency and aesthetics.
- Power Access: Both units require electricity. Planning the installation close to an appropriate power source can simplify wiring and potentially reduce installation costs.
- Efficient Drainage: The indoor unit produces condensate (water) during cooling. This needs to drain away effectively. Ensuring a clear, downward path for the drainage pipe prevents leaks and water damage.
- Minimising Pipe Length: While not always possible, keeping the length of the refrigerant pipes between the indoor and outdoor units as short as possible can contribute to better efficiency. Longer pipe runs can lead to more heat loss/gain and a slight reduction in performance.
Why Professional Placement Matters
Understanding these points is powerful, but executing them perfectly requires expertise. Incorrect installation can lead to higher energy bills, reduced lifespan of your unit, and inconsistent comfort. This is why relying on seasoned professionals like Plum Heating and Cooling is essential.
