            How to Choose the Best Split System in General – Buyers Guide and FAQ

            Simply by looking at the air conditioner brands and models above, you will have a good idea of what to look for in a split system. 

            But if you want to leave the brand debate aside completely, we’ve put together a few features to look for so you can choose the best split air conditioning in Camberwell, throughout Melbourne, and across Australia in 2023.

            10 Key Split System Features and Benefits to Look for

            1. A system that suits your budget: Split systems are among the most affordable and popular types of air conditioners. Be sure to consider both upfront costs (for supply and installation) as well as ongoing expenses (running costs, energy efficiency, maintenance and repair requirements).

            2. The right shape, size, and power capacity: The indoor unit of your split system will be a presence in your home, so think about size and shape in terms of how much room you have available and how the unit will blend with your decor. Also consider the square metres of the room you want to heat/cool. As well as length, width, depth, and shape, you need to consider size in terms of power capacity. If your system is oversized or undersized in terms of power, you will end up overpaying in running costs in the long term!

            3. Energy efficiency features: Check the energy rating for the system you are considering. The higher the energy star rating, the more efficient and affordable your unit will be to run. Other features – like an Economy Mode and DRED (Demand Response Enabling Device) will help you reduce power usage, carbon emissions, and your energy bill both during peak usage and everyday use. 

            4. Fan speeds: Multiple fan speeds allow you to easily increase heating and cooling as required, allowing you to switch your priority from efficiency to performance with ease.

            5. Operating noise: Most split systems claim to be whisper-quiet, but just make sure you check the recorded decibels produced and look for user experiences to back this up. You want a system that’s as quiet as possible when starting up and in operation, even when operating at capacity. Many systems have a “Quiet Mode” or similar that prioritises quiet operation – perfect for overnight air conditioning!

            5. Many modes: We’ve already mentioned a few operating modes your split system might have. Other modes to look out for include Auto Mode, Dry Mode (for dehumidification), and more.

            6. Timers and human sensors: A split system with timers and smart sensors can automatically power down to save you money and increase energy efficiency while promoting rapid heating and cooling and a comfortable flow of air.

            7. A wide operating range: In Australia, it’s good to know that your AC can keep operating at its best when the mercury tips over 40 Celsius or dips below zero. Most split systems offer this kind of operating range. Just make sure your AC is designed for your local climate before you buy.

            8. Cleaning features: Look for a split system with advanced, long-lasting air filters, dehumidification technology, air purification systems, self-cleaning technology, and more!

            9. Wi-Fi compatibility: Most modern Wi-Fi-enabled systems allow you to control your AC through your phone as long as you have a wireless connection. Set timers, run diagnostics, double-check that your system is turned off, pre-cool your home before you arrive, and much more – all thanks to Wi-Fi.

            10. Warranty: You want your split system to last without major problems for at least 10 years, and you should look for a parts and labour warranty that covers at least 5 years!

            8 Split System FAQs

            1. What are they? Split systems are known for being affordable, energy efficient, quiet, and easy to install. Most of all, they’re known for being split into the indoor unit and the outdoor unit. The indoor unit sits high on the wall and the outdoor unit is positioned on or near the exterior of the same wall. Split ACs are space heaters and coolers – meaning they’re designed for climate control in one room only – like the living room or bedroom.

            2. How do they work? Things can get really complicated when explaining how a split air conditioner works. You can talk about refrigerant changing from a gas to a liquid to a vapour and back again! But in a nutshell, these heat pump systems absorb warm air. In doing so, they either remove warm air from your home to create cooling or add warm air from outside for heating. Just like ducted refrigerated cooling, the doors and windows stay closed while in use.

            3. What are the pros and cons? The advantages of split systems include easy installation, small footprint, energy-efficient and affordable to run, quiet operation, and combined heating and cooling. The drawbacks of split systems include heating and cooling for one room only, must install an indoor unit (rather than just having ducts), and outdoor units may be noisy for neighbours.

            4. What is the installation method? To install split systems, a professional will mount the indoor unit and outdoor unit in the ideal positions. A small hole is made, and the two units are connected via a series of small pipes and electrical wires. Installation is fast and simple, with no need for extensive ductwork!

            5. What are inverters and why are they important? An inverter split system refers to a split AC with inverter technology. Essentially, the inverter allows the AC motor to gradually speed up and slow down, rather than just being switched on or switched off. This gradual acceleration and deceleration increases energy efficiency, reduces wear and tear, and contributes to more comfortable airflow.

            6. What is reverse cycle technology and why is it important? Reverse cycle technology is what allows your split system to offer both heating and cooling. Most split systems are reverse cycle these days, but cooling-only models are also available. Make sure you purchase a reverse cycle air conditioner if you want a split system with heating and cooling functionality.

            7. What is a multi-head split system? The indoor unit of a split AC is also known as a head unit. Multi-head split systems, or simply multi-split systems, are set-ups that allow you to run multiple indoor units using just one outdoor unit. This allows you to have heating and cooling in multiple rooms without cluttering your exterior with outdoor units.

            8. Which split AC brand is best in 2023? It’s impossible to say, as every user will have different requirements. You might want a Panasonic system if you prioritise air quality or an ActronAir unit if you love the “Follow Me” function. Daikin is widely considered among the best heating and cooling brands, so you can’t go wrong with a Daikin system. Other options not mentioned on the above list might even be right for you.
