Is it worth buying it?
In general, multi-split ACs are a good option because they are easier to operate and do not significantly affect the image of the facade where they are installed, since they only require a single external unit.
Can you run two splits with just one external unit?
Yes, even more: there are brands that allow up to 8 units to work connected to a single outdoor unit.

What is the average cost?
It will depend mostly on how many areas of your home or business you need to cool since on that basis you will need more or less indoor units but on average it costs between $4,000 and $5,000.
How much does the installation cost?
On average, you could spend between $2000- $3000 just to install your multi-split air conditioning, but the total amount will vary depending on the company doing the installation, as well as the brand and model. Now, on average, aircon professional charges $83 per hour for installation.
On the other hand, in terms of materials, the most important cost to consider during installation is that of pipes, whose average price is $60 per meter. For instance, if you have four indoor units and each one is about four meters away from the compressor, you would be spending $240 for each one’s piped and $960 for all four. This without considering eventual expenses for brackets, poly slab installation and working at heights charges, if any.
How much does it cost to service Sydney multi split AC?
The costs of servicing are equal to those of servicing a single split system, multiplied by the number of units that the system to be serviced has.
Standard servicing for a single split costs $70 includes evaporator casing hand-cleaning, regular operational and remote assessment, condenser-coil flushing, and evaporator-filter sanitizing. On the other hand, premium servicing the above, low-pressure coil-cleansing, removal and sanitizing of evaporator casing, as well as blower/fan, condensate, and drain pan checks, can cost $160.
Thus, if, for instance, your multi-split air conditioning has 3 units, standard servicing would cost $210 and premium servicing, $480.
