If you’re looking for a system that offers the best heating and cooling for your home or office, you will want to explore a system that suits the size of your property. In this article, we explore the features and benefits of a 2.5kW and a 7kW split system air conditioning unit, so you can make an informed choice about the air conditioning unit to suit your needs.

What is a split system air conditioner

One of the most popular types of air conditioning systems, split system air conditioners are designed to heat or cool individual rooms with precision. Whether you’re considering a 7kW and 2.5kW Air Conditioner, these systems are ideal for managing temperature in sectioned-off areas, helping you save on energy by only conditioning the spaces you use.

Split systems are typically mounted high on an interior wall or positioned on a flat roof or wall bracket. The external compressor sits outside the property, minimizing indoor noise and disruption in both homes and commercial spaces.

The system operates through two split components: the outdoor condensing unit generates hot or cold gas, which travels through piping to the indoor unit. These 7kW and 2.5kW Air Conditioner models work by removing heat from indoor air and leaving it cooler and more comfortable.

Using refrigerant, a compressor, and an evaporator, the system efficiently expels heat and balances indoor temperatures. In reverse mode, it delivers warm air in cooler months, offering consistent comfort all year round.

Types of split systems

There is a range of split systems available on the market in Australia including multi-split systems and also inverter cassette air conditioners. Multi-split systems are essentially one outdoor unit that runs multiple indoor units. This is a great solution for when there is limited space outside for more than one unit and if property owners are looking for a more streamlined effect for their air conditioning systems.

Multi-split systems can work to heat or cool up to eight different rooms around the home or office.

The inverter cassette air conditioner works in a similar way to the wall mounted split systems however they draw air in and out of the roof level instead. This means they are a more streamlined system and come out of the roof rather than the wall mirroring more of a ducted air conditioning system.

2.5kW or 7kW split system air conditioner – which ones is best?

If you are looking to invest in a split system air conditioner, you should consider the following factors before deciding upon whether you invest in a 2.5kW system or a 7kW system.

– Geographic location and associated climate
– Size of the room needing to be air conditioned
– Whether you have wall or ceiling insulation
– The size of the window and the direction they face
– Energy efficiency rating

It’s important to find a split system that offers the latest technology to ensure the best energy efficiency, high-quality air conditioning and perfect temperature control for your property.

The split system should be large enough to be able to cool your air efficiently, keep in mind if you choose a system that is too small the split system will have to work too hard to manage heating or cooling.

7kW system information

The perfect size for a standard household, a 7kW split system air conditioning unit is a popular choice for office and residential cooling and heating. The system can cool multiple rooms within a set space.

Made to suit Australian conditions, the 7kW split system air conditioner is designed to offer low average price per watt compared to other sized systems available on the market and also offer increased heating and cooling power throughout a property.

2.5kW system information

Perfect for a bedroom, the 2.5kW split system air conditioner is ideal for one room within a home. Smaller in output and designed for intimate spaces such as consulting rooms, bedrooms, one-room offices, the 2.5kW system is perfect as a small one-room system that works to heat and cool small areas. The system allows for a low sound output as well as heating and cooling as required. The split system will have all the features of the larger 7kW system, however, be suitable for one single room.

Size matters when it comes to split system air conditioners

Size matters when choosing a split system air conditioner. Select a unit that suits your property’s specific heating and cooling needs.

Measure the room size, ceiling height, wall insulation, and window glazing to determine the right system for your space.

Consider shading and property orientation. These elements influence how well your air conditioner performs throughout the day.

Your location also matters. In areas where temperatures drop below 5°C, some systems may struggle to heat the space effectively.

Check with manufacturers for model-specific performance in extreme conditions to ensure it suits your local climate.

Determine your unit’s kW requirement. This indicates the power needed to deliver the rated heating or cooling output.

This information appears on the energy rating label and is available on the manufacturer’s website and marketing materials.

What does the star system mean?

The star rating system helps compare energy efficiency across appliances, including air conditioners, using a 1 to 6-star scale.

Split systems show heating and cooling capacity, key factors in evaluating performance and energy use for different room sizes.

The star rating scale increases in half-star increments, helping you find the most energy-efficient option available.

Higher star ratings mean better energy savings. Choosing a more efficient system reduces long-term power consumption and running costs.

Consider the star rating when comparing models. It’s a simple way to assess value and efficiency side by side.

If you’re buying a split system air conditioner, take time to research and compare systems to meet your exact requirements.

A 2.5kW system is ideal for small rooms. For larger spaces, consider a 7kW unit to ensure consistent comfort.
