Air conditioning installation refers to the process of fitting an AC unit in a home or building to provide cooling during warm weather. With Melbourne's average summer temperatures reaching the mid 30°Cs, having good air conditioning is essential for comfort.
A split system air conditioner is a type of AC unit made up of an outdoor compressor and condenser connected to a slim, wall-mounted indoor unit via refrigerant pipes and cables. Split systems are by far the most popular type of air conditioner installed in Melbourne homes, making up over 80% of residential installations.
The team at Oz Air Group have specialised expertise in recommending, supplying and professionally installing reliable, energy-efficient split system air conditioners across Melbourne. With over 20 years of experience, they know how to select the correctly sized split system to match the unique cooling needs of each space.
Choosing the right type of air conditioning system is important to get value for money. Key factors to consider are upfront costs, estimated yearly running costs, maintenance requirements, size and layout of areas needing cooling, and aesthetic preferences. Getting these decisions right from the start will ensure the system installed meets expectations for many years.
Installing air conditioning differs considerably between residential and commercial settings. Home AC units usually cool individual rooms with simple control by the owner, while commercial buildings require complex central systems zoned into sections and controlled automatically according to occupancy and use. Noise levels also need to be far lower for homes than offices.
The team at Oz Air Group tailor their professional installation service for either residential or commercial settings, ensuring the split system air conditioning meets the unique requirements whether it's for a Melbourne family home or office workspace.
To choose the right air conditioner for your home or office in Melbourne, there are several key factors to consider:

Split system air conditioning installations are considered the top choice for most homes and offices in Melbourne. The temperate climate here with warm summers and cool winters make split system units ideal for effectively providing both heating and cooling without being overpowered.
Split systems have proven to be the most popular type of air conditioner installed across Australia over the past decade thanks to their flexibility, energy efficiency and affordability. As specialists in split system installation, the team at Oz Air Group have fitted over 10000 units across Melbourne and surrounding suburbs. With over 20 years serving the local area, their expertise provides homeowners and businesses the highest quality split system air conditioning solutions tailored for their specific cooling and heating needs all year round.
A split system air conditioner is made up of an outdoor condenser and compressor unit connected by pipes to a stylish indoor unit often mounted high on a wall. They utilise refrigerant to absorb or remove heat from indoor air to provide cooling or heating depending on the climate control settings chosen. Split systems are very quiet, efficient and allow temperature control for individual rooms.
Inside the indoor unit, a filter cleans the air which is then passed over a cold refrigerant coil to lower its temperature, effectively cooling it before being re-circulated back into the room. This cooler air displaces the naturally warmer air in the room which is sucked into the outdoor unit. Here, the refrigerant absorbs the heat from the air and dissipates it outside before being sent back to the indoor unit in a continuous cycle. Reverse cycle split systems also operate in heating mode, with the refrigerant flowing in the opposite direction to take heat from outside and transfer it indoors.


To choose the correct size split system to install, the main factors are:
