Split System Air Conditioner Sydney

The split system air conditioner is the most widely installed type of air conditioning in Sydney homes and businesses, and for good reason. A split system delivers effective, efficient, and quiet cooling and heating for individual rooms or open-plan spaces, with an installation that is far less invasive and expensive than a full ducted system.

Air On Temp supplies and installs split system air conditioners across Sydney from all major brands. Whether you need a single split system for a bedroom, a large wall-mounted unit for an open-plan living area, or a multi-head system connecting several rooms to one outdoor unit, we have the product knowledge and installation expertise to get the right system into your home or business.

Split System Air Conditioner Price and Value

Split AC price varies considerably across brands, capacities, and feature levels. At the entry level, a basic split system for a small bedroom is very accessible. At the premium end, high-efficiency inverter units with advanced filtration, Wi-Fi control, and extended warranties carry a higher price tag that is justified over the life of the system in energy savings and reliability.

Air On Temp advises clients on the best value split system for their specific situation — balancing upfront split system price against long-term running costs, warranty coverage, and the reliability track record of each brand. We do not push the highest-margin product; we recommend what makes sense for your home and budget.

A split system sale price seen online or in a retail catalogue rarely reflects the total cost of ownership – installation, electrical work, and the quality of the installation itself all matter. Air On Temp provides fully inclusive supply-and-install quotes so you can compare accurately.

Types of Split System We Install

Not all split systems are the same. Air On Temp installs the full range of split AC configurations available in the Sydney market:

  • Standard wall-mounted split AC – one indoor wall unit paired with one outdoor compressor. The most common configuration for bedrooms, living rooms, and offices. Available from 2.0kW for small bedrooms up to 9.0kW or more for large open-plan spaces
  • Split system inverter air conditioner — the inverter compressor varies its speed to match the cooling or heating load precisely, rather than running at full power and cycling on and off. The result is lower energy consumption, more precise temperature control, and quieter operation. Virtually all modern split systems are inverter units
  • Multi-head split system – one outdoor unit connected to multiple indoor units in different rooms. Reduces the number of outdoor units required and can be more cost-effective than separate single splits for multi-room installations
  • Wall split system AC for commercial use – higher-capacity units designed for commercial tenancies, offices, and retail spaces where a ceiling cassette is not practical

What size split system air conditioner do I need?
Correct sizing depends on room dimensions, ceiling height, insulation, window area and orientation. As a rough guide, a 2.5kW unit suits rooms up to about 20sqm, a 3.5kW unit suits 20 to 35sqm, and a 5.0kW unit suits 35 to 50sqm — but a proper heat load calculation gives a more accurate result. Air On Temp sizes systems correctly for every installation.
Daikin and Mitsubishi Electric are consistently the most highly regarded brands for reliability, efficiency, and after-sales support. Fujitsu and Panasonic are also strong performers. LG and Kelvinator offer good value at accessible price points. Air On Temp installs all major brands and can discuss the trade-offs for your specific situation.
A quality split system air conditioner, correctly installed and regularly serviced, should last 10 to 15 years or more. The compressor is the component most likely to determine system lifespan — quality brands with strong warranty backing generally correlate with longer compressor life.
Most modern split systems are reverse cycle, meaning they can both cool in summer and heat in winter. This is the standard configuration — single-mode cooling-only systems are now rare in the residential market. Confirm with us when selecting your system if heating is a requirement.
