Installing an air conditioner is a big step towards keeping your home cool in our scorching Australian summers and warm during the chilly winters. But it’s not just about picking the right unit; where and how it’s installed can make a huge difference to its efficiency, lifespan, and even your relationship with your neighbours!
Let’s dive into some common questions about air conditioner clearance requirements down under.
What is the Minimum Clearance Around an AC Unit in Australia?
Getting the right amount of space around your air conditioning unit is crucial for it to work effectively and efficiently. Think of it like giving your AC unit room to breathe!
Outdoor Units (The Big Box Outside): For the outdoor unit, which houses the compressor and fan, proper airflow is key. While specific measurements can vary by manufacturer and unit size, a general rule of thumb for larger outdoor units in Australia suggests:
- Around 300mm (about the length of a standard ruler) of clear space in every direction from the unit itself. This ensures that air can flow freely around it, preventing recirculation of hot air that can reduce efficiency.
- Some sources even recommend a clear zone of 600mm or more from the pipe connection side, with some experienced installers suggesting up to 800mm on the sides and 1600mm in height for larger units. It’s always best to check the manufacturer’s specific guidelines for your model, as not following them could even void your warranty!
- Avoid obstructions within 2 metres of the front of the outdoor unit. If there’s a wall, fence, or even dense plants too close, the air can bounce back towards the unit, causing it to work harder.
Indoor Units (The Sleek Box Inside): The indoor unit, usually mounted on a wall, also needs space for optimal air distribution within your room.
- Aim for at least 15cm (about half a ruler’s length) of clear space around the unit to allow proper airflow and circulation.
- Ideally, these units should be installed high on the wall, generally above 2 metres from the floor. This helps the cool air, which tends to sink, distribute more evenly throughout the room.
How Close Can an Air Conditioner Be to the Property Line in Australia?

This is where it gets a bit tricky. There isn’t a strict rule like “must be X metres from the fence.” Instead, the main concern here is noise pollution and its impact on your neighbours.
Australian regulations focus on ensuring that the noise from your air conditioner doesn’t cause an “unreasonable disturbance” to adjoining properties. This means:
- Location, Location, Location: Air conditioners should not be placed directly next to your neighbour’s windows, bedrooms, or main living areas. Even if it’s on your property, a noisy unit too close can be a big issue.
- Noise Limits: Councils across Australia have varying noise regulations, often specifying a maximum decibel level (dB(A)) that your air conditioner can produce when measured at your property boundary or inside your neighbour’s home. For example, in Victoria, the noise from an AC unit generally shouldn’t exceed the background noise level by more than 5 dB(A) inside a neighbouring home, especially during quiet hours.
- Using Barriers: Solid barriers like fences or garden walls can be a great help! If a fence is solid, blocks the line of sight to the AC unit, and has no gaps, it can significantly reduce noise reaching your neighbours.
Aussie Case Study: The Backyard BBQ Battle Imagine Johnno in Toowoomba, keen to keep his outdoor entertaining area cool. He installs a powerful AC unit right near the shared fence with his neighbour, Sheila. Unfortunately, the unit’s hum travels straight into Sheila’s bedroom window, making it hard for her to sleep. Sheila, after a few restless nights, politely brings it up with Johnno. Johnno, being a good bloke, looks into moving the unit further away and adding a solid acoustic fence. This small change keeps both Johnno cool and Sheila happy, avoiding any formal complaints to the local council.
Can Neighbours Complain About Air Conditioning?
Absolutely, yes! If your air conditioning unit is causing an “unreasonable disturbance” due to noise, your neighbours have every right to complain.
What constitutes “unreasonable noise” can depend on:
- Loudness: Is it excessively loud compared to the usual background noise?
- Time of Day: Noise rules are often stricter during evening and night hours. For instance, many councils have limits on how much noise an AC unit can make between 10 pm and 7 am on weekdays, and 10 pm and 8 am on weekends/public holidays.
- Frequency and Duration: Is the noise constant or occurring frequently?
- Impact: Is it genuinely impacting your neighbour’s quality of life (e.g., disturbing sleep, making it hard to relax)?
What Happens if a Complaint is Made?
- Usually, the first step is a friendly chat between neighbours.
- If that doesn’t resolve it, your neighbour might lodge a formal complaint with your local council or the Environmental Protection Authority (EPA) in your state.
- The council might then investigate, which could involve measuring the noise levels. If your unit is found to be too noisy, you could receive a warning letter, an on-the-spot fine, or even be ordered to switch off or relocate the unit.
What are the New Requirements for Air Conditioners?
Australia is always looking to improve energy efficiency and environmental protection, and air conditioners are no exception! There have been some important updates regarding new AC units:
1. Energy Efficiency Standards:
- Zoned Energy Rating Label: New non-ducted household air conditioners now come with a Zoned Energy Rating Label. This label is super handy because it shows how efficient the unit is in Australia’s different climate zones (hot, average, and cold). This helps you pick a unit that performs best where you live, saving you money on electricity bills! The old energy rating labels are being phased out by 2025.
- Minimum Energy Performance Standards (MEPS): From 1 October 2022, larger air conditioners (over 65kW cooling capacity) have stricter minimum energy performance standards they must meet before they can be sold in Australia. This pushes manufacturers to create more energy-efficient models.
2. Refrigerant Regulations (Environmental Protection):
- Australia is actively phasing down the use of refrigerants with high Global Warming Potential (GWP) to protect our environment.
- From 1 July 2024, there’s a ban on importing and manufacturing certain small air conditioning equipment (like portable, window/wall, and single split systems) that use refrigerants with a GWP over 750, unless licensed.
- A similar ban for multi-head split system air conditioning equipment (including variable refrigerant flow systems) with a GWP over 750 comes into effect from 1 July 2025.
- Don’t fret if you have an older unit! These bans apply to newly imported or manufactured equipment; existing units aren’t affected and can still be sold if they were made or imported before these dates until stock runs out.
- Only licensed technicians with a Refrigerant Handling Licence can work on equipment containing these refrigerants, and businesses dealing with them need a Refrigerant Trading Authorisation.
Aussie Case Study: The Eco-Conscious Homeowner Meet Sarah, an environmentally aware homeowner in Brisbane. When her old ducted air conditioner gives up the ghost, she consults with an installer. The installer explains the new Zoned Energy Rating Label and the upcoming refrigerant bans. Sarah chooses a highly energy-efficient unit with a lower GWP refrigerant that’s perfect for Brisbane’s hot climate, ensuring she stays cool while also doing her bit for the environment and complying with the latest standards.
Wrapping It Up
Understanding these clearance and regulatory requirements is vital for any Australian homeowner considering a new air conditioner. By ensuring proper installation, respecting noise limits, and choosing energy-efficient models, you can enjoy a comfortable home environment without causing a fuss. Always consult with a licensed and reputable air conditioning professional for advice tailored to your specific situation and local council regulations. They’re the best blokes and sheilas to get the job done right!
