The short answer: It depends — and getting it wrong can cost you.
“How long is a piece of string?” That’s usually the first response we give when someone asks what size air conditioner they need. Because the truth is, there’s no one-size-fits-all answer.
Just like you wouldn’t buy shoes based on your neighbour’s foot size, you shouldn’t choose an air conditioner based on someone else’s setup — even if your rooms lookthe same.
Why Size Isn’t Just a Number
When we talk about “size” in air conditioning, we mean cooling and heating capacity, not how big the unit looks on the wall. It’s measured in kilowatts (kW), and choosing the wrong size — too small or too large — can cause more headaches than you might expect.
Undersized? You’ll Pay For It in the Long Run.
An air conditioner that’s too small for the space will struggle to keep up, especially on those 40+ degree summer days we know all too well on the Eyre Peninsula.
The system will run constantly, working overtime without ever quite reaching your desired temperature. That means:
It’s like trying to tow a caravan with a hatchback — it might move, but it’s going to burn out pretty fast.
Oversized? Sounds Better, But Isn’t.
Bigger isn’t better when it comes to air conditioning. An oversized system might cool the room quickly, but it won’t run long enough to dehumidify properly — leaving the air feeling clammy and uncomfortable.
Worse, it’ll cycle on and off repeatedly, which:
You’ll be paying more upfront and more every month — without getting better comfort.
What Actually Affects the Right Size?
There’s more to it than just square metres. At Cool Eyre, we look at:
Even two rooms that are the same size on paper might need different systems based on how they’re built and used.
So How Do You Get It Right?
Here’s the simple 3-step plan we follow:
1. Book a site visit
We come to your property and assess the space properly — measuring, inspecting, and asking the right questions.
2. Get expert advice
We calculate your heating and cooling needs accurately. No guesswork, just honest recommendations tailored to your home or business.
3. Choose the right system
We match you with a perfectly sized Mitsubishi Heavy Industries or Gree system — based on what actually works, not what’s trending.
The Risks of Getting It Wrong
The wrong size system is more than just an annoyance. It can lead to:
When temperatures spike on the Eyre Peninsula, you don’t want to find out your system isn’t up to the task.
The Smart Move? Get It Sized Professionally.
Proper sizing isn’t a luxury — it’s the foundation of comfort, efficiency, and system longevity. And it's not something you should leave to guesswork, internet calculators, or generic advice from a hardware store aisle.
At Cool Eyre, we’re locals. We understand the climate, the construction styles, and what actually works in regional SA homes.
The Bottom Line
Don’t let a too-small or too-big system make life harder (and more expensive) than it needs to be. With a correctly sized air conditioner, you get:

When people ask us whether they really need a reverse cycle ducted system, what they’re often asking is: “Is it worth the investment?” And like most good investments, the answer depends on how you use your home — but for many Eyre Peninsula households, ducted reverse cycle systems are a game-changer.
Let’s break it down.
What Is a Reverse Cycle Ducted System?
In simple terms, it’s a central heating and cooling system that uses a single, powerful unit to condition the air throughout your home — delivered through ducts and vents in the ceiling or floor.
Reverse cycle means it works for both heating and cooling, giving you year-round climate control from a single system.
Ducted means you can control the comfort in every room, or just the ones you’re using — thanks to zoning options.
Why People Choose Ducted Reverse Cycle
Here’s why so many homeowners are making the switch:
1. Whole-Home Comfort
Whether it's 40°C outside in January or freezing on a winter morning, ducted systems keep your entire home at a consistent, comfortable temperature. No more cold bedrooms or hot living rooms — just even, reliable climate control.
2. Zoned Heating and Cooling
You’re in control. Want to heat the whole house before bed? Done. Only need the living area cool during the day? No problem. Zones let you run only the areas you need — saving energy and money.
3. Clean, Sleek Aesthetics
No wall units. No bulky boxes. Ducted systems are tucked away in your roof space, with discreet vents that blend into your home’s design. It’s all the comfort, without the visual clutter.
4. One System, All Seasons
No separate heaters. No portable fans. Just one professionally installed system that handles everything. Reverse cycle technology means you’re getting efficient cooling and heating from the same unit — with no compromise.
But Do YouNeed One?
That depends. Here’s how to tell if ducted might be right for you:
What’s the Alternative?
If you're only cooling one or two rooms, or your home layout doesn’t suit ducted installation, a split system might be a better fit. But for many family homes, ducted reverse cycle offers the best combination of:
Local Expertise Matters
At Cool Eyre, we don’t just sell systems — we tailor them. We’ll assess your home, explain your options, and give you honest advice about what will actually work for your lifestyle and budget.
We understand how important reliable heating and cooling is here on the Eyre Peninsula — because we live here too. And we know how to size, zone, and install ducted systems properly so they deliver comfort for years to come.
The Bottom Line
A reverse cycle ducted system isn’t just an upgrade — it’s an investment in whole-home comfort, control, and efficiency. You can heat or cool your entire house, just a few rooms, or even a single zone — all at the touch of a button.

The short answer: Some parts, yes. The important bits? Probably not. Would you service your car yourself?
For most of us, that's a firm no. Sure, we might check the oil or pump up the tyres, but when it comes to the complex stuff - the engine diagnostics, brake systems, or transmission work - we head straight to a professional mechanic. Your air conditioning system deserves the same respect.
What You Can (and Should) Do Yourself
Just like basic car maintenance, there are simple tasks that every homeowner can handle:
Filter Cleaning and Replacement This is your equivalent of checking the oil. Clean filters every few weeks during heavy use, and replace them when they're beyond cleaning. It's straightforward, costs very little, and makes a real difference to your system's performance.
Keep the Outdoor Unit Clear Remove leaves, debris, and anything else that might block airflow around your outdoor unit. Think of it like keeping your car's radiator clear - good airflow is essential for efficient operation.
Basic Visual Checks Look for obvious issues like ice buildup, unusual noises, or water leaks. You don't need to fix these yourself, but spotting them early can prevent bigger problems.
What Professionals Handle (and Why It Matters)
Here's where the car analogy really kicks in. Modern air conditioning systems are sophisticated pieces of equipment with refrigerant systems, electrical components, and precision controls that require proper tools and training to service safely.
Refrigerant Levels and Leak Detection
Checking and adjusting refrigerant isn't like topping up your windscreen washer fluid. It requires specialized equipment, proper handling procedures, and understanding of environmental regulations. Get this wrong, and you could damage your system or create safety hazards.
Electrical System Inspection
Air conditioners involve high-voltage electrical components. A professional technician knows how to safely test connections, check capacitors, and diagnose electrical faults without risking electrocution or system damage.
Deep System Cleaning
While you can clean your filters, a thorough service involves cleaning the evaporator coils, condensate drains, and internal components that you simply can't reach safely. This deep cleaning is crucial for maintaining efficiency and preventing breakdowns.
Performance Testing and Calibration
Professional servicing includes testing system performance, checking temperature differentials, and ensuring all components are working within specifications. This kind of diagnostic work requires experience and proper testing equipment.
The Stakes Are Higher Than You Think
Here's the thing about air conditioning on the Eyre Peninsula - we don't miss it until it doesn't work when we need it most. When that scorching summer day hits and your system fails, you're not just uncomfortable, you're potentially facing health risks and emergency repair costs. Professional servicing catches problems before they become failures. That slightly low refrigerant level or gradually failing capacitor might not stop your system today, but it's working your compressor harder and shortening its life. By the time you notice the problem, what could have been a simple fix during routine maintenance has become an expensive component replacement.
The Smart Approach to Air Conditioning Maintenance
Think of air conditioning maintenance like car servicing - some things you do yourself, but the important stuff gets professional attention.
Your part: Keep filters clean, maintain clear airflow around the outdoor unit, and watch for obvious problems.
Professional's part: Annual comprehensive service that includes refrigerant checking, electrical testing, deep cleaning, and performance optimization.
This approach gives you the best of both worlds - you're actively caring for your investment with regular simple maintenance, while ensuring the complex technical work is handled by someone with the right tools, training, and experience.
When DIY Goes Wrong
We've seen the results of well-intentioned DIY servicing gone wrong. Damaged coils from incorrect cleaning methods, refrigerant leaks from amateur repairs, and electrical issues from poking around where you shouldn't. These aren't just inconvenient - they're expensive to fix and potentially dangerous. The money you save by skipping professional servicing is often dwarfed by the cost of repairing DIY mistakes or replacing components that failed prematurely due to poor maintenance.
The Bottom Line
Your air conditioning system is a significant investment that works hard in Peninsula conditions. Like your car, it deserves professional care for the complex stuff while you handle the simple maintenance tasks. Clean your filters regularly, keep the outdoor unit clear, and watch for problems - but leave the technical servicing to professionals who have the right tools and knowledge to keep your system running reliably for years to come.

The short answer: It depends on your home, your budget, and how you live in your space.
When choosing between a split system and a ducted system, it’s not about which is “better” — it’s about which suits your lifestyle. Both have their strengths, and picking the right one can mean the difference between efficient comfort and long-term frustration.
Let’s break it down.
What’s the Difference?
Ducted Systems: Whole-Home Comfort
A ducted system uses a central unit to heat or cool your entire home via vents in each room. The key advantages?
It’s ideal if you want year-round comfort across your whole home, especially in family houses or larger builds.
Split Systems: Targeted Climate Control
Split systems are individual units mounted on walls, perfect for single rooms or smaller spaces. They’re a great choice if:
Split systems are flexible, efficient, and easier to install — ideal for bedrooms, offices, or small open-plan areas.
Which One Should You Choose?
Here’s a quick guide:
Building or renovating a full home? Ducted
Upgrading climate control in one room? Split
Want clean, hidden vents (no wall units)? Ducted
Need quick installation or tighter budget? Split
Want separate control over multiple areas? Ducted (with zoning)
Renting or just cooling a bedroom/office? Split
Local Homes, Local Expertise
Here on the Eyre Peninsula, we install both systems every week — and we always start with a proper assessment. Why? Because no two homes are the same. Whether you're in a weatherboard cottage in Kimba or a new build in Port Lincoln, we'll help you find the system that actually works for your space.
Our approach is simple:
The Bottom Line
Both can be energy-efficient, both can be quiet, and both can be installed professionally — it’s just about choosing what works for your household.

We’ll assess your space and walk you through the pros and cons — so you end up with a system that keeps you comfortable for years to come.
The short answer: At least once a year. More often if your system works hard or lives in a challenging environment.
Your air conditioner is one of the hardest-working systems in your home, especially here on the Eyre Peninsula where summer heat and winter chills are no joke. Just like your car needs regular servicing to keep running smoothly, your air conditioner needs scheduled maintenance to perform at its best.
Why Annual Servicing is Essential
At Cool Eyre, we recommend a professional service every 12 months.
Even if your system seems to be working fine, small issues can build up over time — reducing efficiency, increasing energy use, and putting strain on key components. Regular servicing keeps your unit:
Annual servicing also allows us to catch potential problems early, often saving you from more expensive repairs down the track.
When More Frequent Servicing is a Good Idea
Some homes and situations call for more than just a once-a-year check. You may need servicing every 6 months if:
In these cases, a more frequent service schedule will help maintain performance and prevent damage from environmental wear and tear.
What’s Included in a Professional Service?
When we service your system at Cool Eyre, we go beyond a basic clean. Our full maintenance service includes:
We make sure your system is safe, efficient, and ready for the season ahead — whether that’s bracing for a heatwave or preparing for winter cold.
The Bottom Line
Annual air conditioner servicing isn’t a luxury — it’s smart preventative maintenance that saves money, reduces breakdowns, and keeps your system running reliably when you need it most.
Not sure when your last service was?
We can help you set up a maintenance schedule and send you reminders when it's time.
