Split system or ducted air conditioner: what's the difference?
Split system air conditioners feature an indoor unit connected to an outdoor compressor. They're generally designed to heat or cool individual rooms or open-plan spaces. The price to install a split system air conditioner is usually lower than ducted air conditioning, making it a popular option for bedrooms, living areas and smaller homes.
Ducted air conditioning distributes heated or cooled air throughout the home using concealed ducts and vents. It generally costs more to install but can provide whole-home comfort, particularly when combined with zoning controls.
For homeowners comparing systems, the split system air conditioner installation cost may be more affordable upfront, while ducted air conditioning can suit larger properties requiring temperature control across multiple rooms.

How does home size affect air conditioning installation costs?
Larger homes generally require greater heating and cooling capacity, which can increase installation costs. A small apartment may only need one split system, while a larger family home might require several split systems or a ducted system.
However, floor area isn't the only consideration. Ceiling height, insulation, window size, orientation and room layout can influence the capacity required.
A qualified installer can assess your home's heating and cooling requirements and recommend an appropriately sized system.

What additional air conditioning installation costs should homeowners consider?
Beyond purchasing the unit and paying for standard installation, homeowners may need to budget for:
- electrical upgrades or dedicated circuits
- additional refrigerant piping and drainage
- wall brackets, concrete pads or outdoor unit supports
- removal and disposal of existing air conditioning equipment
- repairs or modifications to walls and ceilings.
Ongoing electricity consumption, servicing and maintenance should also be considered when comparing the long-term costs of different systems.

Does the location of the air conditioner affect installation costs?
Yes. Where the indoor and outdoor units are positioned can significantly affect installation costs.
A straightforward split system installation typically places the outdoor unit directly behind the indoor unit, minimising pipework and labour. Installing units further apart, on upper storeys or in difficult-to-access locations may increase costs.
Outdoor units also need adequate ventilation and suitable clearance. Noise, neighbouring properties and any applicable owners corporation or planning requirements should be considered.

When is the best time to install air conditioning in Melbourne?
You can arrange an air conditioning installation at any time of year, although wait times may be longer during periods of high demand.
Spring can be a convenient time to install cooling, while autumn may suit systems that provide both heating and cooling. Demand is often lower outside the peak summer and winter periods, which may give you more flexibility when booking an installer.
