Ducted systems deliver whole-home climate control with discreet vents and zoned temperature settings. Ideal for larger homes or open-plan spaces, they offer consistent airflow and a clean finish without visible units.
Split systems are great for single rooms or small areas. With quiet operation and strong cooling performance, they’re easy to install, energy-efficient and perfect for bedrooms, offices or living spaces needing targeted comfort.
Cassette units sit flush in the ceiling, providing 360-degree airflow without cluttering wall space. They suit modern interiors and commercial spaces, offering quiet operation, easy access for servicing and powerful cooling performance.
Multi-split systems connect multiple indoor units to a single outdoor compressor. They’re ideal for homes needing flexibility — cooling different rooms independently while saving on outdoor space and energy. Perfect for growing families or multi-use properties.
Sunshine Coast Air Conditioning
If you're tired of air conditioning that barely keeps up, we get it — you're not asking for much, just comfort that actually lasts. At Allchin Airconditioning & Refrigeration Electrical, we’ve been helping Sunshine Coast locals stay cool since 2002. From our base in Caloundra, we install, maintain and repair air conditioning systems in homes, businesses and even caravans.
We work with all major system types — ducted, split, cassette and multi-split — and only recommend brands we trust like Daikin, Panasonic, Fujitsu and LG. Whether you're upgrading an old system or need help with a new build, we’ll guide you through the process and make sure it’s done right the first time.
We’re also fully licensed for warranty servicing and offer ongoing maintenance to keep your system running like it should. Reach out to us on 0447 347 428 to book today.

Smart Air Conditioning for Any Setup
We know that no two spaces are the same — what works in a single-bedroom unit won’t cut it in a five-zone family home or busy retail store. That’s why we take the time to match you with the right system, explain your options clearly and make sure you get the comfort and efficiency you’re paying for.
Alongside our air conditioning work, we also offer electrical services, caravan cooling installs, coldroom construction and mobile fridge repairs. We handle everything ourselves — no chasing multiple trades or waiting on callbacks. Need a split system serviced? We’ll clean and test it properly. Ducted system acting up? We’ll check the zoning, gas and airflow and sort it.
And if you need a fast response, we’ve got emergency callouts and flexible booking times too. We’re a Sunshine Coast family business, and we treat every job like it’s for our own home.
Frequently Asked Questions
What’s the best type of air conditioning for my home?
It depends on your layout, budget and how many rooms you want to cool. Split systems are great for one or two rooms, while ducted air conditioning works well across an entire home with even cooling. Multi-split systems are good when you need different temperatures in separate areas using one outdoor unit.
For open spaces or commercial areas, cassette units blend into ceilings and push airflow evenly. If you're unsure, a licensed technician can inspect your space and help you choose based on insulation, window placement and daily use.
How often should I get my air conditioner serviced?
For most homes, once a year is ideal. If you live near the beach or run your system constantly, it might need servicing every six months. Servicing includes checking refrigerant levels, cleaning filters and coils, inspecting electrical components and testing airflow.
Regular maintenance improves efficiency, prevents breakdowns and extends the life of your system. Skipping it can lead to clogged filters, high power bills and poor cooling.
Why is my air conditioner running but not cooling?
There are a few common reasons. It could be a dirty filter, low refrigerant levels, a blocked outdoor unit or a failing compressor. Sometimes, the thermostat settings are off or the system is simply too old to keep up.
If your system’s blowing air but the room isn’t cooling, it’s best to have a technician check it. They can run diagnostics, find the cause and give you options — whether it’s a simple clean or a full repair.
Do you need a licensed technician to install air conditioning?
Yes, and for good reason. Installing an air conditioner involves handling refrigerants, electrical wiring and compliance with safety codes. In Queensland, only licensed contractors with ARCtick certification can legally install or service systems.
A licensed installer will ensure correct sizing, placement, drainage and power supply — so your system runs efficiently and safely. DIY or unlicensed installs can void warranties and even be dangerous. Always ask to see a licence before the work starts.
How can I use my air conditioner more efficiently?
You can use your air conditioner more efficiently by keeping your temperature around 24° in summer, using timers, only using your air conditioner when you need it, closing all windows.
What’s the difference between a central air conditioning system and a ductless mini-split system?
A central air conditioning system uses a series of ducts to distribute cool air throughout your home, while a ductless mini-split system uses individual units to cool specific areas of your home. The choice between the two depends on factors such as the size of your home, the layout of your ductwork and your budget.
I have an older air conditioner that is over a decade old. Should I get it fixed or replaced?
Generally speaking, when an air conditioner reaches the end of its lifespan, it’s usually a good idea to replace the unit rather than repair it. You might be able to get another year or two out of your existing unit, but it’s eventually going to fail. We recommend investing in a new unit if your old one is giving you problems.
