Selecting the right split system size is essential to maintaining the comfort of your space without incurring excessive energy costs. A unit that is too big will waste energy and your hard-earned money, while one that is too tiny will have trouble cooling the space. Here is a general sizing guide:

• 10–20 m² rooms require a 2.5 kW system.
• 20-30m² rooms require a 3.5kW system.
• 30-45m² rooms require a 5-6kW system.
• 45-65m² rooms require a 7-8kW system

It’s important to also consider the room’s insulation, ceiling height, and windows. For example, rooms with high ceilings or large windows facing the sun will need more power to cool down. To get a more accurate estimate of the size of the system you will need contact us for a free quote.

High-quality air conditioning systems that can withstand both intense heat and freezing winters are necessary due to Australia’s climate. These air conditioners are our top picks for dependability, longevity, and energy efficiency out of all the ones we’ve installed:

• MIDEA
• HISENSE
• MITSUBISHI ELECTRIC
• CARRIER
• PANASONIC

These companies are frequently commended for their longevity, energy-efficient models, and silent operation. Reverse-cycle split systems are popular among homeowners because they provide both heating and cooling, making them perfect for year-round comfort.

A pro suggestion is to get high energy-star rated systems because they will save you money over time even though they may cost a little more up front.

The complexity of the job can affect how much it costs to install a split system. Installing a split system air conditioner typically costs $1800 + GST. Please note, if electrical changes (such as longer pipe runs or switchboard upgrades) are required, more expenses could be incurred. These costs exclude the actual cost of the air conditioner, which varies based on size and brand and can be anywhere from $600 to $5000.

Advantages:

• Split systems are effective in heating and cooling a single room, particularly those with reverse cycles.
• Installation expenses are typically reduced because ducts are not required.
• Running costs are generally lower than ducted systems primarily because ducted systems require you to cool/heat multiple rooms that you may not be using rather than just one.
• Multiple units can be placed in various rooms to provide zoned climate control. So you can simply heat or cool the rooms as you like.

Disadvantages:

• Although split systems make more noise than ducted systems, they are now incredibly quiet. Ultimately, it is a matter of preference.
• They are more appropriate for cooling a single room than a whole house.
• You can see the interior unit on your wall, which might not be to everyone’s taste.

The annual cost of heating and cooling a medium-sized room in Melbourne is about $300 and $45 respectively. The annual cost to operate a large room is $470 for heating and $70 for cooling. The height of your ceilings and the amount of direct sunlight the space receives will affect these expenses. Importantly, a major factor in lowering operating expenses is the split system’s energy efficiency. A high energy star rating and inverter technology, which makes the unit run more smoothly and efficiently, are desirable features.
