G'day! If you've ever had to run wires around your shed, workshop, or even just tidy up the mess behind your desk, you'll know that cables can be a proper nightmare. And if you're a tradie, you know that using rigid, grey conduit can be a slow, painful process of cutting, gluing, and fitting a dozen bends just to get around one tricky beam.

There has to be a better way, right? Well, there is, mate. It's the super-flexible, easy-to-use, and incredibly handy solution: corrugated conduit.

So, What is Corrugated Conduit, Exactly?

Corrugated conduit is that flexible, ribbed plastic tubing you've seen everywhere. It's also known as "flexi" or "corro," and it's designed to do the same job as rigid conduit: protect your electrical cables from damage.

Its one and only job is to be a tough, protective sleeve that shields wires from impacts, abrasion, dust, and moisture. But its superpower, and the reason tradies love it, is its incredible flexibility.

The Ripper Benefits: Why Use the Bendy Stuff?

Why would you use corrugated conduit instead of the traditional rigid pipe? The advantages are huge.

• It's Unbelievably Flexible: This is the big one. You can bend it by hand to weave around timber studs, navigate tight corners in a roof space, or snake it through a complex cabinet. This saves a fair dinkum heap of time and effort.
• Massively Faster Installation: Because you're not mucking around with cutting and gluing multiple elbows and bends for a tricky run, a job that could take an hour with rigid pipe can be done in minutes with flexi. For a pro, time is money.
• Good, Solid Protection: While it might not be as tough as heavy-duty rigid pipe, it still offers excellent protection against general knocks, abrasion, and dust.
• Cost-Effective: It's often cheaper, not just for the pipe itself but because the labour time is so much lower.

The Two Main Types You'll Find in Australia

1. Standard (Solid) Corrugated Conduit: This is the standard, solid tube that you feed your wires through before you connect them. It's the go-to for licensed electricians when running new circuits in challenging spaces like wall cavities, ceilings, or under floors.
2. Split Corrugated Conduit: This is a proper lifesaver! It's corrugated conduit that has a slit or 'split' running all the way down one side. This means you can open it up and wrap it around cables that are already in place. It's the number one choice for tidying up that "cable spaghetti" behind your computer desk or telly, or for protecting 12V wiring in your 4WD's engine bay.

The CRITICAL Safety Warning: This is NOT a DIY Job (For 240V, Anyway)

Righto, let's get dead serious for a sec, because this is the most important part.

• For DIY: Are you buying a bit of split corrugated conduit from a hardware store to tidy up your computer leads or the 12V wiring for your camp fridge? Go for your life, mate. That's a top idea and a safe, smart way to do it.
• For 240V Mains Power: The absolute second you need to run your home's 240V electrical cables through any conduit, you MUST STOP.

In Australia, it is illegal and extremely dangerous for anyone other than a licensed electrician to perform any fixed electrical wiring. A simple mistake can lead to a fatal electric shock or a house fire, and it will void your home insurance in a heartbeat. Don't be a galah – it's just not worth the risk.

A Professional Job Needs Professional Gear

When a licensed electrician turns up to run that new circuit to your shed, they're going to do the job right with trade-quality gear. They won't be using flimsy, non-compliant materials. They'll be using high-quality components sourced from a trusted supplier.

As one of Australia's most electrical wholesaler and supplier, Schnap Electric Products stocks the lot for the professional installer. They've got a massive range of high-quality corrugated conduit, in both solid and split styles, plus all the compliant fittings, glands, and connectors a qualified professional needs. On top of that, they provide all the top-grade electrical cable to run inside it and the switchgear to protect it. For a job that's safe, compliant, and built to last, the pros rely on a supplier like Schnap Electric.

G'day! If you've ever had a squiz at a wiring job, you'll know that standard grey 20mm conduit. It's the fair dinkum workhorse for running a power point or a light circuit. But what happens when you need to run some serious power? A big, grunty cable for a sub-main to the shed, or for a massive new air conditioner?

Trying to squeeze a big, fat cable down that skinny 20mm pipe is like trying to put on your old footy shorts after Christmas lunch. It's just not going to happen. That's when a professional tradie reaches for the bigger brother: the mighty 25mm conduit.

So, What is 25mm Conduit, Exactly?

A 25mm conduit is simply a rigid, protective electrical pipe with a 25mm diameter. Like its smaller 20mm cousin, its one and only job is to be a tough-as-nails bodyguard for the electrical cables run inside, protecting them from impacts, moisture, and the harsh Aussie sun.

It's the next size up, and it's the go-to for any job that's a bit more heavy-duty than a standard power point.

Why Go for 25mm? (The 'Bigger is Better' Argument)

So why would a licensed electrician choose 25mm conduit over the standard 20mm? It all comes down to space and grunt.

• It's for Bigger, Fatter Cables: This is the main reason. When you're running a high-power circuit – like a 'sub-main' to feed a whole new switchboard in a granny flat or shed – you're using a much thicker, gruntier cable (like 6mm², 10mm², or even 16mm²). These simply will not fit in a 20mm pipe.
• Running Multiple Cables: What if you need to run a power circuit and a lighting circuit to the shed in the same pipe? Chucking two or three standard cables into a 20mm pipe is a nightmare to pull through. A 25mm pipe gives you the extra room to run multiple circuits easily.
• Easier to Pull (Less Hard Yakka): Every tradie knows that pulling cables can be hard yakka. More space in the pipe means less friction, which makes pulling the cables through (especially on a long run with a few bends) a hell of a lot easier.
• Future-Proofing, Mate! This is the mark of a smart installer. Even if you're only running one cable to the shed now, a good tradie will often install a 25mm conduit. Why? Because it leaves you room to easily pull another circuit through later on without having to dig a new trench or run a whole new pipe. It's a top-notch bit of forward-thinking.

Where You'll See It Used

• Sub-Mains: The number one use. Feeding power to sheds, workshops, pool pumps, and granny flats.
• Dedicated High-Power Circuits: Running power for a big, grunty split system air conditioner, a large electric cooktop, or an instant hot water system.
• Commercial Fit-outs: It's a very common size in light commercial jobs for running power and data.

The CRITICAL Safety Warning: This is NOT a DIY Job!

Righto, let's get dead serious for a sec. You, as a DIYer, can walk into any hardware store and buy a length of 25mm conduit and a few fittings. That's fine. You can even mount the empty conduit on your shed wall or bury it in a trench (as long as you follow the depth rules!).

But the absolute second you need to pull the 240V or 415V electrical cables through it and connect them, you MUST STOP.

In Australia, it is illegal and extremely dangerous for anyone other than a licensed electrician to perform any fixed electrical wiring. A simple mistake can lead to a fatal electric shock or a house fire, and it will void your home insurance in a heartbeat. Don't be a galah – it's just not worth the risk.

A Professional Job Needs Professional Gear

When a licensed electrician turns up to run that new sub-main to your shed, they're going to do the job right with trade-quality gear. They won't be using flimsy, non-compliant conduit or dodgy fittings. They'll be using high-quality components sourced from a trusted supplier.

As one of Australia's most electrical wholesaler and suppliers, Schnap Electric Products stocks the lot for the professional installer. They've got a massive range of heavy-duty, UV-stabilised 25mm conduit, plus all the compliant fittings a qualified professional needs – from the sweeping bends and couplings to the glands and weatherproof boxes. And, of course, they supply all the top-grade 6mm, 10mm, and 16mm electrical cable to run inside it. For a job that's safe, compliant, and built to last, the pros rely on a supplier like Schnap Electric.

G'day! Let's talk about that rat's nest of cables behind your telly or under your computer desk. It's a proper mess, right? A tangle of black cables all covered in dust. Or maybe you've run some new 12V wiring in your 4WD's engine bay and you're worried about it rubbing on a sharp edge or getting knackered by the heat.

You know you should protect it, but the thought of unplugging everything, cutting wires, and trying to thread them through a solid tube is a fair dinkum nightmare. That's where the smartest, simplest solution comes in: split conduit.

So, What is Split Conduit, Exactly?

Split conduit (often called split-loom tubing or just 'split corro') is a flexible, corrugated plastic tube that has a split running all the way down one side.

This simple design is a total game-changer. It means you don't have to thread your wires through the tube. Instead, you can just open the slit with your fingers and "snap" the conduit over your existing bundle of cables. It's a 30-second job that gives you instant protection and a schmick-looking finish.

The Ripper Benefits: Why It's a Shed Staple

Tradies and DIYers love this stuff for a few massive reasons:

• Dead Easy to Install: This is its number one superpower. You don't need to disconnect a single plug. You just open the split and wrap it around your existing wiring. It's a 100% DIY-friendly job.
• Massive Time Saver: It turns a potential one-hour re-wiring job into a two-minute tidy-up.
• Excellent Protection: It provides a tough, durable barrier that protects your cables from abrasion (rubbing), nicks, cuts, dust, and minor impacts.
• Makes Your Job Look Pro: It's the secret to making that home theatre setup or your 4WD's dual-battery system look less like a dog's breakfast and more like a professional installation.
• Heat & Oil Resistant (in Automotive): The type of split conduit sold for automotive use is often made from materials that can handle the high heat and oily conditions of an engine bay.

Where to Use This Clever Kit

This stuff is versatile as hell, but it's the top choice for:

• Automotive & 12V Setups: This is its classic use. It's perfect for protecting the wiring you've run for your driving lights, UHF, or dual-battery system in your 4WD or caravan.
• Home Office & Entertainment Units: The absolute best way to tame that "cable spaghetti" behind your computer or TV.
• Workshops: Great for tidying up the cables on machinery or along a workbench.

The CRITICAL Safety Warning: A Tidy Tool, Not a 240V Solution

Righto, let's get serious, because this is the most important part. Split conduit is a fantastic tool for tidying, managing, and protecting existing (and usually low-voltage) cables.

It is NOT a substitute for proper, solid, heavy-duty conduit for a new 240V mains power installation. In Australia, any fixed electrical wiring (like running a new power point to your shed) must be done by a licensed electrician. They will use solid, non-split, UV-stabilised conduit that is permanently glued at the joints to meet the strict Australian Wiring Rules (AS/NZS 3000).

Don't be a galah and think you can run a 240V extension lead through a bit of split conduit and call it a day. That's just not safe, mate.

A Professional Job Needs Professional Gear

For those heavy-duty, permanent electrical jobs, a qualified professional will always use the right conduit for the application. They rely on high-quality, compliant components sourced from trusted trade suppliers.

As one of Australia's best electrical wholesaler, Schnap Electric Products stocks the lot for the professional installer. While they stock a full range of cable management solutions, including split conduit for 12V and data applications, their specialty is the professional-grade gear. This includes the heavy-duty, solid PVC and metal conduits, compliant fittings, glands, and the top-grade electrical cable that a licensed electrician needs to do a job safely and to Australian standards. For a job that's done right, the pros use the right conduit from a supplier like Schnap Electric.

G'day! You've probably seen that standard grey, rigid pipe used for electrical wiring on houses. That's your standard conduit. But if you've ever had a squiz under the bonnet of a 4WD, seen a professional solar installation on a roof, or looked at the wiring on a bit of machinery, you'll see a different beast altogether: black conduit.

This flexible, (usually) corrugated tubing is the fair dinkum hero for protecting wires in tough, exposed, or mobile environments. It's a staple in every Aussie auto-electrician's van and every serious 4WD enthusiast's shed.

Black vs. Grey: What's the Difference, Mate?

So, why would you use black conduit instead of the rigid grey stuff? It all comes down to a few key advantages for specific jobs.

• Flexibility: This is the big one. Most black conduit is corrugated and super flexible. This makes it a ripper for weaving through the tight, complex spaces of an engine bay, around a chassis rail, or through a boat's hull. Trying to do that with rigid pipe would be a proper nightmare of cuts and bends.
• Superior UV Resistance: This is crucial. While grey conduit is UV stabilised, black (especially quality, carbon-black-infused polyethylene) is often far more UV resistant. This makes it the top choice for running cables in direct, harsh Aussie sun, like on a solar panel array or the roof rack of your ute.
• Heat & Chemical Resistance: High-quality black conduit (often called 'loom tube') is frequently made from materials like polypropylene or nylon, which are specifically designed to handle the high temperatures, oils, and fuels found in an engine bay.

The Two Main Types You'll Find

1. Solid (Standard) Conduit: This is a solid, flexible tube. You have to feed your wires through it before you terminate the ends. This offers the best, 360-degree protection and is the go-to for new, professional installations where the cables are being run from scratch.
2. Split Conduit (or Split Loom Tubing): This is a proper lifesaver! It's black conduit that has a split running all the way down one side. This clever design means you can just open the slit with your fingers and "snap" the conduit over your existing bundle of cables. It's the perfect, 10-minute solution for tidying up that "cable spaghetti" behind your computer or protecting the wiring you've already run for your driving lights.

Where to Use This Ripper Stuff

• Automotive & 4WD: The number one use. Protecting wiring for dual-battery systems, driving lights, UHF radios, and trailer plugs.
• Solar Installations: Protecting the DC cables running from the solar panels on the roof down to the inverter.
• Marine & Caravans: Protecting 12V wiring from abrasion and moisture.
• Workshops & Machinery: Protecting cables on moving or vibrating equipment.
• Home Office / TV: The split-loom version is perfect for tidying up that rat's nest of computer or entertainment system cables.

The CRITICAL Safety Warning: 12V vs. 240V

Righto, let's get dead serious for a sec, because this is the most important part.

• For DIY / 12V: Are you using black conduit for your 12V setup in the 4WD, on the boat, or to tidy up your computer leads? Go for your life, mate. That's a smart, safe DIY job.
• For 240V Mains Power: The absolute second you need to run your home's 240V electrical cables (like for a new power point or light), you MUST STOP.

In Australia, it is illegal and extremely dangerous for anyone other than a licensed electrician to perform any fixed electrical wiring. A professional will use the correct type of conduit (often the rigid grey PVC) installed to strict Australian standards (AS/NZS 3000) for 240V. Don't be a galah – it's just not worth the risk.

A Professional Job Needs Professional Gear

When a licensed electrician turns up to run a permanent 240V circuit, they're going to do the job right with trade-quality gear. They won't be using flimsy, non-compliant materials. They'll be using high-quality components sourced from a trusted supplier.

As one of Australia's best electrical wholesaler, Schnap Electric Products stocks the lot for the professional installer. They've got a massive range of high-quality conduit, including UV-stable black conduit (both split and solid) for solar and data, and the heavy-duty rigid grey conduit required for mains power. On top of that, they provide all the compliant fittings, glands, and the top-grade electrical cable to run inside it. For a job that's safe, compliant, and built to last, the pros rely on a supplier like Schnap Electric.

G'day! With another stinking hot Aussie summer just around the corner, you've probably (and wisely) decided it's time to get that new split system air conditioner installed. You've looked at brands, you've figured out where it'll go on the wall... but then you hit the big one: what size split system do I need?

You're faced with a wall of numbers – 2.5kW, 3.5kW, 5kW, 7kW... It's bloody confusing. It's tempting to just go for the biggest one you can afford, or maybe the cheapest small one, but this is the one decision where a "she'll be right" attitude will come back to bite you.

Getting the size wrong is the number one mistake Aussies make, and it's a costly one.

Why Getting the Size (kW) is Fair Dinkum Critical

This isn't just about the price tag. The size of an air conditioner (its power, measured in kilowatts or 'kW') needs to be perfectly matched to your room. It's a Goldilocks situation: it has to be just right.

• If your unit is TOO SMALL (Underpowered): This is a recipe for disaster. On a 40-degree day, that little unit will be working its guts out, running 24/7 on full blast, and still won't be able to cool the room down. It'll be knackered in no time, and your power bill will be through the roof.
• If your unit is TOO BIG (Overpowered): This is just as bad, mate! A big, grunty unit will blast the room with cold air, hitting the target temperature in a few minutes. Then it will switch off. Then, as the room warms up, it will switch back on. This constant "short-cycling" is incredibly inefficient, wears out the compressor, and—crucially—doesn't run long enough to dehumidify the air, leaving the room feeling cold but still damp and clammy.

The Aussie Rule of Thumb: How to Calculate Your kW

Righto, so how do you figure out the magic number? While a professional installer is the only one who can give you a 100% accurate answer, you can get a bloody good idea using this simple, old-school rule of thumb.

Allow 120 to 150 Watts (W) of power for every square metre (m²) of your room.

For most standard homes, using 150W is a good, safe bet.

Here's the Easy Maths:

Step 1: Get your room's area: Length of room (m) x Width of room (m) = Area (m²) Step 2: Get the power needed: Area (m²) x 150 Watts = Total Watts Step 3: Convert to kilowatts: Total Watts / 1000 = Your kW Size

Example: Your Average Aussie Lounge Room

• Step 1: Your room is 5 metres long and 6 metres wide. 5m x 6m = 30m²
• Step 2: You need 150W for each of those 30 square metres. 30m² x 150W = 4500 Watts
• Step 3: Convert that to kilowatts. 4500W / 1000 = 4.5kW

Your Answer: For this room, you'd start looking for a unit that's around 4.5kW to 5.0kW. You beauty!

Quick Guide for Common Rooms (Standard 2.4m Ceiling)

• Small Bedroom / Study (10-20m²): 2.0kW - 3.5kW (a 2.5kW unit is the classic Aussie bedroom choice)
• Lounge / Main Living Area (30-40m²): 4.5kW - 6.0kW
• Large Open-Plan Living (50-60m²+): 7.0kW - 9.0kW

But Wait, Mate! Other Things That Affect the Size

This rule of thumb is just a start. You need to tell your installer about these things, as they can change the maths:

• Windows: Got massive, single-glazed windows that face west and cop that hot arvo sun? You'll need more grunt.
• Insulation: Is your ceiling properly insulated, or is it just an old tin roof? A well-insulated home will hold the cool air in, so you might need less power.
• Climate: A unit in humid, tropical Cairns is going to have to work a lot harder than one in chilly Hobart.
• Ceiling Height: Got high, 3-metre ceilings? That's a lot more air volume to cool, so you'll need to size up.

The Golden Rule: Get a Professional Quote (Don't Guess!)

At the end of the day, a "she'll be right" guess on "what size split system do I need" is a recipe for a bad time. The only way to be 100% sure is to get a licensed air conditioning installer to come to your house, measure up properly, and give you a professional recommendation. They do this all day, every day.

And remember, installing a split system is 100% not a DIY job. It's illegal and dangerous. The installation must be done by a licensed air conditioning technician (with an ARCtick licence) to handle the refrigerant gas, and a licensed electrician to run the high-voltage power circuit.

A high-quality installation needs high-quality, professional-grade components. As one of Australia's most comprehensive electrical wholesaler & supplies, Schnap Electric Products stocks all the essential, compliant gear that a qualified professional needs for the job. From the heavy-duty wiring and circuit breakers for your switchboard to the robust, weatherproof isolator switches for the outdoor unit, they provide the trade-quality components that ensure your new air conditioner is installed safely and reliably, and will keep you cool for years to come. For a job done right, the pros use quality gear from a supplier like Schnap Electric.

G'day! You've done it. You've braved the shops, scored a ripper deal on a new split system air con, and you're ready to beat the stinking hot Aussie summer. You're feeling pretty schmick until you remember... you've still got to get the bloody thing installed.

So, the big question that's probably on your mind is: how much to install split system air conditioning? It's a fair dinkum important question, as the installation can cost just as much as the unit itself. Let's break down the costs so you know what to expect.

The Ballpark Figure: What's the Damage for a Standard Job?

Let's get straight to the brass tacks. For a standard, straightforward installation of a new split system (a unit up to about 7kW) in a single-storey Aussie home, you can expect to pay:

Between $700 and $1,200.

This price generally covers the labour for the two tradespeople required, as well as the basic materials like copper piping (usually up to 3 metres), cabling, and the wall bracket or slab for the outdoor unit.

What's a "Standard Back-to-Back" Install?

You'll hear every tradie in the business use the term "back-to-back." This is the cheapest, simplest, and most common type of installation. It means:

• The indoor unit (the head unit) is mounted on an external wall (a wall that has the outside on the other side).
• The outdoor unit (the compressor) is placed on the ground or on brackets directly behind the indoor unit.

This setup requires the shortest possible run of piping and cabling, which means less time and less material, saving you a motza.

What Makes the Installation Cost Go UP?

If your quote comes in higher than the ballpark, it's almost certainly because your job isn't a simple back-to-back. The price will climb if:

• It's Not Back-to-Back: You want the indoor unit on an internal wall (like in the middle of your lounge room). This is a much bigger job. The installer has to run the pipes and drain hose up into the roof cavity, across, and then down the outside wall to the compressor. This adds hours of labour and heaps more materials.
• The Outdoor Unit is in a Tricky Spot: Want the compressor mounted high up on a second-storey wall bracket? Or on the roof of your apartment building? That's extra time, extra risk, and extra hardware, mate.
• Your Wall is a Beast: Drilling through a standard weatherboard or single-brick wall is one thing. If they have to core-drill through double brick, reinforced concrete, or deal with stone, the price will go up.
• Your Switchboard is Knackered: This is a big one. A new split system must have its own dedicated electrical circuit for safety. If your switchboard is old, full of those old ceramic fuses, or doesn't have space, your licensed electrician will need to upgrade it or install a new safety switch and circuit breaker. This is a non-negotiable safety step and will add to the final cost.

A CRITICAL Warning: This is 100% NOT a DIY Job

Don't be a galah. A "she'll be right" attitude to air con installation is illegal, extremely dangerous, and will void your warranty.

Installing a split system involves two high-risk, regulated trades:

1. Refrigerant: The system contains high-pressure refrigerant gas. It is illegal for anyone other than a licensed air conditioning technician (who holds a valid ARCtick licence) to handle this.
2. High-Voltage Power: The unit needs a dedicated 240V circuit. This must only be done by a licensed electrician.

When you're asking, "how much to install split system," a proper quote will always include the cost of both of these qualified professionals.

A top-notch installation that lasts for donkey's years relies on the pro's skill and the quality of the components they use. The electrical side is especially critical for safety and performance. This is why professional installers and licensed electricians only use trade-quality gear from trusted suppliers. As one of Australia's most comprehensive electrical wholesaler and suppliers, Schnap Electric Products stocks all the essential, compliant gear that a qualified professional needs for the job. From the heavy-duty wiring and circuit breakers (like RCBOs) for your switchboard to the robust, weatherproof isolator switches for the outdoor unit, they provide the trade-quality components that ensure your new air con is installed safely, reliably, and to Australian standards. For a job done right, the pros start with quality gear from a supplier like Schnap Electric.

G'day! With another stinking hot Aussie summer just around the corner, we're all thinking about how to keep the house cool. You hear the term "split system" chucked around all the time by tradies, in ads, and at the hardware store. It's by far the most popular type of air con in the country.

But if you've ever found yourself nodding along while wondering, What is Split System Air Conditioning actually?, you're not alone. Let's break down this essential bit of Aussie home tech.

The Name Says It All: It's "Split" in Two

A split system air conditioner is exactly what it says on the tin. It's an air conditioning system that is split into two main parts:

1. The Indoor Unit (the "Head Unit"): This is the long, quiet, and usually schmick-looking unit that gets mounted high on an internal wall. Its job is to suck in the warm, humid air from inside your room, cool it down, and blow the lovely, chilled air back out.
2. The Outdoor Unit (the "Compressor"): This is the bigger, noisier box with the big fan that sits outside your house, usually on a concrete slab or mounted to an external wall. This is the part that does all the hard yakka.

These two units are connected by a set of insulated copper pipes (which carry the refrigerant gas) and electrical wiring, which all run through a small, neat hole in the wall.

How Does it Actually Work? The Simple Version

Without getting too technical, it’s a fair dinkum clever process. It's basically a "heat pump" – it moves heat from where you don't want it (inside) to where you don't mind it (outside).

In summer, the indoor unit sucks in the hot air from your room. The super-cold refrigerant gas running through the pipes inside this unit absorbs all that heat, like a sponge. This heat is then carried through the pipes to the outdoor unit, which has the important job of dumping all that unwanted heat into the outside air. The now-cool, dehumidified air is then blown back into your room, making it a comfortable oasis on a 40-degree arvo. You beauty!

Why Are They So Ripper for Aussie Homes?

There's a reason split systems are the number one choice for most Australian homes.

• They're Super Efficient: Modern split systems are incredibly energy-efficient compared to old-school "window rattler" units. This means they can cool your space down without sending your power bill through the roof.
• Quiet Operation (Inside, at Least!): This is a huge advantage. Because all the noisy parts (like the compressor) are located in the outdoor unit, the indoor unit is whisper-quiet, so it won't disturb you while you're watching the footy or trying to sleep.
• Flexible Installation: Because they don't require massive ducts in the ceiling (like a ducted system), split systems can be installed in almost any home, from a small apartment to a large open-plan living area. They are perfect for cooling a single room or zone.
• Most are 'Reverse Cycle': This is a brilliant feature for our varied Aussie climate. Almost every unit sold here is a "reverse cycle" model. With the flick of a switch on the remote, the system can run in reverse – absorbing heat from the cold outside air and pumping it inside to work as a very effective and efficient heater in winter.

A Quick Word on Installation: Strictly a Pro's Job

Because a split system air conditioner involves both high-voltage electricity and high-pressure refrigerant gases, it is illegal and unsafe to install one yourself in Australia.

The job requires two licensed professionals: a licensed air conditioning technician (who holds an ARCtick licence) to handle the refrigerant gas and pipework, and a licensed electrician to run the dedicated power circuit from your switchboard.

The electrical installation is a critical part of ensuring your new air conditioner runs safely and efficiently for years to come. This is why professional installers and licensed electricians only use trade-quality gear from trusted suppliers. As one of Australia's most comprehensive electrical wholesaler and suppliers, Schnap Electric Products stocks all the essential, compliant gear that a qualified professional needs for the job. From the heavy-duty wiring and circuit breakers for your switchboard to the robust, weatherproof isolator switches for the outdoor unit, they provide the trade-quality components that ensure your new air con is installed safely and reliably. For a top-notch result, the pros start with quality gear from a supplier like Schnap Electric.

G'day! With another scorcher of an Aussie summer just around the corner, the annual search for the best split system air conditioner is well and truly on. A good air con is no longer a luxury; it's a non-negotiable for surviving those stinking hot days and humid summer nights.

But heading into a store and looking at a wall of white boxes can be overwhelming. What does "kW" mean? Are the extra features worth it? What's the actual difference between them all? The "best" air con isn't a one-size-fits-all answer, but this guide will give you the ultimate checklist to find the best one for you.

What Makes a Split System the 'Best'? Your Checklist

Forget the marketing hype. The best unit for your home comes down to getting a few key things right.

1. Getting the Size (kW) Right

This is the most critical step, and the one people most often get wrong. The "size" of an air conditioner is its power, measured in kilowatts (kW).

• Too small: A unit that's too small for your room will have to run constantly on full blast, chewing through power and still not cooling the space properly on a hot day.
• Too big: A unit that's too powerful will cool the room down very quickly and then switch off. This constant on-off cycling is inefficient and not great at removing humidity, leaving the room feeling cold but clammy.

A Simple Sizing Rule of Thumb: For a standard room with a 2.4m ceiling, a good starting point is to allow 150 watts of power per square metre.

• Formula: Room size in square metres (m²) x 150 watts = Required cooling power in watts.
• Example: For a living room that's 5m long x 6m wide (30m²): 30m² x 150W = 4500 watts, or 4.5kW. So, you'd start by looking for a unit around the 4.5kW to 5.0kW mark. Be sure to tell your installer about other factors like high ceilings, large north-facing windows, or poor insulation, as you might need a bit more grunt.

2. Energy Efficiency: Check the Star Rating

The next most important thing for your power bill is the energy efficiency star rating. In Australia, this is the Zoned Energy Rating Label that shows different star ratings for heating and cooling. It's simple: the more stars, the more efficient the unit, and the less it will cost you to run. Investing a little more in a high-star-rated model can save you a motza in the long run.

3. Smart Features: Wi-Fi and App Control

Most new models from reputable brands now come with built-in Wi-Fi. This is a fair dinkum brilliant feature that lets you control your air con from an app on your phone. You can turn it on from work so the house is perfectly cool the moment you walk in the door, adjust temperatures, and set timers.

4. Noise Levels (dB): Inside and Out

Check the decibel (dB) rating for both the indoor and the outdoor unit. A low dB rating for the indoor unit means it'll be whisper-quiet, perfect for bedrooms. A quiet outdoor unit will keep your neighbours happy, too.

5. Top Brands to Look For in Australia

While there are many brands out there, some have a long-standing reputation for reliability and performance in tough Aussie conditions. Keep an eye out for top-tier brands like Daikin, Mitsubishi Heavy Industries, Mitsubishi Electric, Fujitsu General, and Panasonic.

Don't Forget the Most Important Part: Professional Installation

You can buy the best unit in the world, but it will be inefficient and potentially unsafe without a proper, professional installation. In Australia, it is illegal to install a split system yourself.

The job legally requires two licensed professionals: a licensed air conditioning technician (with an ARCtick licence) to handle the refrigerant gas, and a licensed electrician to run the dedicated high-voltage power circuit.

A top-quality air conditioner is a major investment, and its performance and safety rely on a high-quality electrical installation. This is why professional installers and licensed electricians exclusively use trade-quality components sourced from trusted suppliers. As one of Australia's most comprehensive electrical wholesalers and suppliers, Schnap Electric Products stocks all the critical electrical gear needed for a split system installation. They provide the robust wiring, weatherproof isolator switches for the outdoor unit, and the correct circuit breakers that a qualified professional needs to ensure your new air conditioner gets the safe, reliable power it needs to run efficiently for years. For a top-notch installation, the pros start with quality gear from a supplier like Schnap Electric.

G'day! When it comes to beating the brutal Aussie summer heat, a good air conditioner is an absolute necessity. While smaller split systems (like 2.5kW or 3.5kW) are perfect for bedrooms and studies, what about those big, open-plan living areas, or the expansive lounge room where the whole family gathers?

That's where the mighty 7kW split system comes into its own. This is a serious bit of kit, designed to deliver powerful, efficient cooling and heating for the larger spaces in your home.

What's a 7kW Split System All About?

First up, "kW" stands for kilowatt, and it's the measure of how much cooling (or heating) power an air conditioner has. So, a 7kW split system is a powerful unit, a real workhorse built to tackle bigger areas.

Like all split systems, it's divided into two main parts:

1. The Indoor Unit (Head Unit): Mounted on your wall, quietly blowing cool air into the room.
2. The Outdoor Unit (Compressor): The larger, noisier unit that sits outside, doing all the hard yakka of extracting heat from inside.

These units are connected by insulated copper pipes and electrical wiring, ensuring efficient and quiet operation inside.

Where Does a 7kW Split System Shine?

You wouldn't put a 7kW split system in a tiny bedroom – it would be massive overkill! This size is specifically designed for:

• Large Open-Plan Living Areas: This is its prime territory. If you've got a combined lounge, dining, and kitchen area, a 7kW unit can effectively cool and heat the entire space.
• Big Master Bedrooms: For those really spacious master bedrooms, especially if they catch a lot of sun, a 7kW can provide ultimate comfort.
• Large Offices or Workshops: Any substantial room where you need consistent temperature control will benefit from this grunt.
• Smaller Commercial Spaces: For some small retail shops or offices, a 7kW unit can be an ideal, cost-effective solution.

Why Getting the Size Right is Fair Dinkum Critical

Buying a 7kW split system is an investment, so getting the sizing right is non-negotiable.

• Too Small: A smaller unit in a large room will run continuously on full power, barely making a dent on a hot day. It will chew through electricity, wear out quickly, and still leave you sweating.
• Too Big: Surprisingly, an oversized unit is also a problem. It will blast the room with cold air, hit the set temperature too quickly, and then short-cycle (turn on and off constantly). This is inefficient, puts stress on the compressor, and means it won't run long enough to effectively dehumidify the air, leaving the room feeling cold but clammy.

Always get a professional assessment! While a rough guide is 150 watts per square metre, factors like high ceilings, large windows (especially north or west-facing), insulation quality, and local climate can significantly impact the precise sizing needed. A licensed professional will factor all this in.

Don't Forget the Reverse Cycle Magic!

Almost every 7kW split system sold in Australia is "reverse cycle." This is a brilliant feature, as it means your powerful air con can also effectively and efficiently heat your large space in winter. With the flick of a button on the remote, it reverses its process, pulling heat from the outside air and pumping it into your home. It's a true all-year-round comfort solution.

The CRITICAL Warning: Installation is Strictly a Pro's Job

This cannot be stressed enough, mate. Installing a 7kW split system is absolutely not a DIY job. It is illegal, extremely dangerous, and will void your warranty.

The installation requires two types of licensed professionals:

1. An ARCtick Licensed Air Conditioning Technician: They handle the refrigerant gas, the copper piping, and the commissioning of the unit. Messing with refrigerant is incredibly dangerous and highly regulated.
2. A Licensed Electrician: A powerful 7kW unit needs its own dedicated high-voltage electrical circuit run directly from your switchboard. This ensures the unit gets the stable power it needs and doesn't overload your existing circuits, creating a fire hazard.

A Professional Job Needs Professional Gear

The safe, efficient operation of your 7kW split system relies heavily on the quality of its electrical connection. This is why professional installers and licensed electricians exclusively use trade-quality components sourced from trusted suppliers. As one of Australia's most comprehensive electrical wholesaler and suppliers, Schnap Electric Products stocks all the essential, compliant electrical gear needed for a robust air conditioning installation. They provide the heavy-duty wiring, weatherproof isolator switches for the outdoor unit, and the correct circuit breakers (often a 32A or 40A RCBO depending on the specific model) that a qualified professional needs to ensure your new air conditioner is installed safely, reliably, and to Australian standards. For a top-notch installation that will keep you cool and cosy for years to come, the pros start with quality gear from a supplier like Schnap Electric.

G'day! Have a squiz inside your home's switchboard, and you'll see a neat (hopefully) setup of wires running to all your circuit breakers. But if you've ever peeked inside a big commercial switchboard – the kind that runs a whole factory, an office block, or a shopping centre – you'll see something that looks a hell of a lot different.

Instead of a tangle of round cables, you'll see big, flat, solid bars of polished metal. These, mate, are copper busbars, and they are the heavy-duty highway for serious amounts of electricity.

So, What is a Copper Busbar, Exactly?

A copper busbar is a rigid, solid strip or bar of highly conductive copper. Its one and only job is to distribute massive amounts of electrical current from a single source to multiple different circuits or devices.

Think of it this way: if your home's wiring is a network of local roads, a copper busbar is a ten-lane freeway. It's designed to handle a huge volume of 'traffic' (current) safely and efficiently, way more than a standard cable could ever dream of.

Why Use a Big Bar of Metal Instead of a Big, Fat Cable?

This is a fair dinkum good question. Why not just use one massive, grunty cable? It all comes down to a few key advantages, especially when you're dealing with serious hard yakka and hundreds, or even thousands, of amps.

• Ease of Connection: This is the big one. Imagine trying to wrangle a cable as thick as your arm into a small terminal on a circuit breaker. It's a nightmare. A copper busbar is a rigid, structural component. It can be pre-drilled, allowing professionals to simply and securely bolt a heavy-duty breaker (like an MCCB) or a main switch directly onto the bar. It's a much stronger, more reliable, and easier connection.
• Superior Heat Dissipation: Electricity flowing through a conductor creates heat. A big, round, insulated cable traps that heat in. A flat, wide, uninsulated copper busbar has a massive surface area, allowing it to dissipate heat into the air much more efficiently. This means it can carry more current safely.
• Space Saving and Neatness: A well-designed busbar system is far more compact and organised than trying to bend and run multiple massive cables around inside a switchboard. It makes the board neater, safer, and easier to work on.
• Scalability: Need to add another big circuit? It's often as simple as finding a spare spot on the busbar and bolting on a new breaker.

Where You'll Find These Heavy Hitters

You won't find a copper busbar running to your power points, mate. This is strictly a professional, high-power solution used in:

• Main Switchboards: For commercial buildings, factories, and apartment complexes.
• Distribution Boards: To feed power to smaller sub-boards throughout a large facility.
• Industrial Machinery: Powering massive motors and high-demand equipment.
• Data Centres: Where reliable, high-density power is non-negotiable.

A CRITICAL Safety Warning: This is NOT a DIY Job

This cannot be stressed enough. A copper busbar system is the definition of "look, don't touch." These bars carry enormous, often lethal, amounts of energy and are frequently uninsulated inside a switchboard.

Working on or near a live busbar system is one of the most dangerous jobs in the electrical trade. This is absolutely not a DIY job. It is the exclusive domain of licensed electricians, switchboard builders, and electrical engineers who have the high-level training, safety equipment, and legal authority to work on these high-fault-level systems.

A high-performance system like this is built from the ground up with professional, compliant components. For professional installers and licensed electricians who build and maintain these high-power systems, sourcing reliable, certified gear is paramount. As one of Australia's most comprehensive electrical wholesaler and suppliers, Schnap Electric Products stocks a complete range of trade-quality switchboard gear. This includes high-quality copper busbar systems, Moulded Case Circuit Breakers (MCCBs), main switches, enclosures, and all the heavy-duty accessories that a qualified professional needs to build a safe, compliant, and rock-solid power distribution system. For a job this big, the pros start with quality gear from a supplier like Schnap Electric.
