Summer is here, and having an air conditioning system has become a necessity. Whether you want it for your small house or commercial space, choosing the right AC is important.
The needs of a residential home are very different from those of a commercial space. There’s no one-size-fits-all solution, from small split systems in apartments to fully zoned ducted air conditioning for large office buildings. That’s why it’s so important to make an informed choice based on your property type, lifestyle, and budget.
In this guide, we’ll explain everything you need to know to choose the perfect air conditioning system for your home or business. The guide will cover split vs. ducted systems, brand recommendations, maintenance tips, and more.
Let’s start with the basics.
What to Consider Before Choosing an Air Conditioning System
Coolness matters, but nowadays selecting the right air conditioning system for your home or business isn’t just about checking the coolness. It’s about choosing a machine that matches your needs.
Here are some factors to consider before buying.
Room Size
You need to consider your room size before as the first step. Smaller rooms like bedrooms or home offices only require a split system air conditioning installation, while larger open-plan areas or entire homes often benefit from ducted solutions. High ceilings, windows, and how sunlight hits your property can all affect cooling efficiency.
Number of Rooms & Zoning
If you’re looking to cool multiple rooms or separate areas, zoning is a smart feature to consider. Ducted air conditioning allows for advanced zoning. Zoning allows you to control temperatures in different parts of the house or office. It’s best for energy savings and comfort.
Home vs Commercial Property Needs
Commercial spaces usually have more complex requirements, including larger floor areas, more occupants, and stricter regulations. Offices or retail spaces may need systems running more extended hours and offering consistent airflow. On the other hand, homes may focus more on aesthetics, quiet operation, and innovative automation features.
Building Structure & Installation Options
Is your property already fitted with ductwork, or is there space to add it? If not, a split system might be more practical. Ducted air conditioning installation experts can assess your ceiling space and advise whether your property is suitable for ducts or if a wall-mounted unit is a better fit.
Energy Efficiency & Environmental Impact
High Energy Star ratings and inverter technology may cost a little, but they help reduce electricity bills. Energy-efficient systems also contribute to lower carbon emissions, a growing concern for many homeowners.
Budget: Upfront vs Long-Term Costs
While a split system may have a lower installation cost, ducted systems often provide better whole-home efficiency over time—factor in ongoing expenses like air conditioning maintenance and energy usage when budgeting for your AC.
Lifestyle Preferences
Consider what matters most: quiet operation, minimalist aesthetics, smartphone control, or air purification. These preferences can guide you toward the best air conditioner for your lifestyle.
Now that you know the factors to consider, let’s jump to Split AC vs Ducted AC.
Types of Air Conditioning Systems
There are two types of air conditioning systems you can get. Both of them are for different needs. Let’s take a look at both of them.
Split System Air Conditioning: Best for Small to Medium Spaces
The most popular type of AC is split air conditioning system. If you want coolness for a single room, or you have smaller to medium spaces, split air conditioning is the choice for you.
How It Works
A split system has two main units. An indoor unit is where the cooling comes from and an outdoor unit that throws the heat out. The two are connected via piping, with no need for so work. So, they are ideal for properties where space is limited.
Benefits of Split System Air Conditioning
- Quick and easy installation with minimal disruption
- Cost-effective upfront and over time
- Targeted cooling runs only when and where you need it.
- Modern designs blend well with home decor.
- Some models offer heating for year-round comfort.
Ideal for These Spaces
Split systems are best suited to:
- Apartments and townhouses
- Single rooms (like bedrooms or living areas)
- Home offices or studios
- Granny flats or small retail spaces
Their compact size and efficient performance make them a go-to for small to medium-sized spaces..
Things to Consider
While split systems are excellent for targeted use, they don’t offer whole-home coverage. If you’re cooling multiple rooms, you may need several units. Alternatively, you can also consider a ducted system. Also, overuse in large areas may result in inefficiency.
Energy & Maintenance
Modern split systems, especially inverter models, are known for their high energy efficiency. To keep yours running smoothly, schedule regular air conditioning maintenance and cleaning. This helps maintain airflow across the room.
Ducted Air Conditioning: Ideal for Whole-Home or Office Cooling
If you’re looking for a freezing, cool solution that covers every room, ducted air conditioning is hard to beat. Popular in larger homes and commercial properties, ducted systems offer energy-efficient climate control with maximum comfort.
How It Works
A ducted system has a central unit ( installed in the roof) connected to a network of ducts. These ducts help distribute cooled air throughout the building. Vents are neatly positioned in the ceiling or walls, allowing for even airflow and an uncluttered look.
Benefits of Ducted Air Conditioning
- Zoning capability lets you control temperatures in different areas.
- Sleek, minimalist appearance with no bulky indoor units
- Quiet operation for bedrooms, offices, and open-plan living
- Improved resale value and whole-home comfort
Best Suited For
- Large family homes or double-storey properties
- Multi-room or open-plan living spaces
- Commercial offices or retail showrooms
- New builds or major renovations where ducting is easier to install
Installation & Cost Considerations
A ducted air conditioning installation is more than a split. It also has a higher upfront cost. However, when installed properly, it provides better long-term value.
It’s important to work with ducted air conditioning installation experts as they will help you plan a proper layout for the installation.
Cleaning & Maintenance
Regular ducted air conditioning cleaning is required more often to maintain air quality. Over time, dust and debris will keep increasing, which reduces airflow and increasing energy usage. Scheduled air conditioning maintenance keeps everything running smoothly, especially during hot summer months.
Which is Right for you: Split system or ducted AC?
Not sure whether to go with a split system or ducted air conditioning? Here’s a side-by-side comparison to help you decide based on your space, budget, and lifestyle needs.
| Feature | Split System | Ducted System |
| Best For | Single rooms | Entire property |
| Cost | $$ (lower upfront cost) | $$$$ (higher investment) |
| Installation | Easy, non-invasive | Complex, requires ceiling space |
| Aesthetics | Visible indoor unit | Hidden vents, sleek finish |
| Zoning | Limited to one area | Advanced multi-room control |
A split system air conditioning installation is ideal for simple, affordable cooling for one or two rooms—perfect for apartments, bedrooms, or home offices.
On the other hand, ducted air conditioning is better suited for whole-home comfort or commercial spaces as it offers quiet, efficient cooling with complete zoning flexibility and minimal visual impact.
Both systems have their strengths, and the best ceally comes down to your property layout, cooling goals, and budget. Not sure which one is right for you? Our experts are happy to help you weigh the pros and cons.
Real-Life Examples: AC Systems for Different Property Types
Choosing the right air conditioning system is hard, as you need to consider several factors. Let’s take some real-life scenarios and a conditioning system you will need.
Scenario 1: 2-Bedroom Apartment
A 2-bedroom flat is categorised as a compact place. A split system air conditioning is often the best choice you can make. These units are easy to install and cost you less. You can install one unit in the living area and another in the master bedroom. Most people often only have one system for 1 room. Plus, the sleek design of split AC means they won’t take up too much space.
Scenario 2: Large Family Home
A ducted air conditioning system is preferred for larger homes with multiple rooms where every room needs an AC. It provides whole-home cooling with zoning, so every room has temperature control. The ducted AC units are not visible. So, you won’t spoil the look or space of your room.
Scenario 3: Open-Plan Office
A ducted system or a multi-head split system works best in this case. Both options provide cooling across large, open spaces. A ducted system allows for discreet airflow, while a multi-head split system can target different zones without the need for extensive ducting.
Each property type has unique needs, whether you’re after a simple solution or a whole-home system, we can help you choose the right AC solution. Our team is ready to assess your space and recommend the best system for you!
It’s you who buy it; you need many of them, one of which is ongoing maintenance costs.
Understand Ongoing Costs: Maintenance, Cleaning & Repairs
Installing an air conditioning system is just the beginning. There are multiple things that you need to take care of. It applies to both, whether you go with a split system or a ducted setup, regular air conditioning maintenance is a must-have process. With this, you can avoid large repairs and maintain indoor comfort.
Why Maintenance Matters
Routine servicing helps keep your system and air clean. If not maintained, it may cause issues such as filter clogging. When the filter is clogged, the airflow decreases, and you may also see unusual noises. Above all, it increases your power bill as the compressor needs more power to pass air through clogged filters. Some of these minor faults could also bring an unusually large expense.. Let’s talk about some small and big maintenance issues.
Common Repair Needs
- AC gas leaks (often due to damaged or ageing components)
- Faulty thermostats or sensors
- Leaking or blocked drain pipes
- Electrical faults or worn-out capacitors
If you suspect a refrigerant issue, book an AC gas leak repair promptly, as gas leaks can affect both performance and health.
Cleaning Saves Money
Regular air conditioning cleaning not only improves airflow and indoor air quality but also extends the life of your system. Dust, mould, and debris build-up can force your AC compressor to use more energy and risk breakdowns. Clean systems are cheaper to run and much healthier too.
Unique Challenges
Living in Australia means dealing with salty coastal air, urban dust, and unpredictable weather. These factors make regular air conditioning maintenance even more important.

After Purchase: Always use a License Installer
When it comes to air conditioning installation, it might be tempting to cut costs, but choosing a licensed professional is the smartest move you can make. Whether you’re installing a split system or a complex ducted air conditioning system, using a licensed installer ensures your investment is protected and your system performs at its best.
Professional Workmanship & Peace of Mind
Licensed installers are trained to work safely and to a high standard. So, your system has been set up correctly since day one. They’ll assess your property’s layout, size, and insulation to recommend the most suitable system. Avoid over- or under-powered solutions that waste energy.
Code Compliance & Warranty Protection
In NSW, air conditioning work must comply with strict regulations, especially when electrical or refrigerant work is involved. A licensed installer will make sure your system meets all local codes and manufacturer guidelines. Skipping this step can void your warranty and lead to expensive repair issues down the track.
Better Efficiency & Longer System Lifespan
Incorrect installation can lead to poor airflow, higher energy bills, and may damage the unit. By choosing one of the best air conditioning installers, you’ll get a system that runs efficiently, quietly, and reliably. It saves you money in the long run.
Don’t risk it with DIY or unqualified installers. Get the job done right with a licensed professional.
