Key takeaway
Single-split suits one room, multi-split covers several from one outdoor unit, and ducted systems are the most discreet.
The main types of system
Home air conditioning comes in a few different forms, and the right one depends on how many rooms you want to cover and the layout of your home. Our team will recommend the best fit after a free assessment.
Common options
- Single-split: one indoor unit for one room
- Multi-split: several indoor units from one outdoor unit
- Ducted: hidden units delivering air through vents
Choosing the right type for your home
A single-split system is ideal for cooling and heating one key room, such as a bedroom or living room. A multi-split lets you control several rooms independently from a single outdoor unit, which keeps the outside of your home tidy. Ducted systems are the most discreet of all, hiding the units away and delivering air through neat ceiling vents.
What we recommend
Because every home and household is different, we never take a one-size-fits-all approach. During your free assessment we look at your rooms, your priorities and your budget, then recommend the type and number of units that will keep you comfortable without spending more than you need to.
Frequently asked questions
What is the difference between single and multi-split?
A single-split system pairs one indoor unit with one outdoor unit to serve a single room. A multi-split connects several indoor units to one outdoor unit, letting you control several rooms independently while keeping just one unit outside.
Which type is most discreet?
Ducted systems are the most discreet, as the units are hidden and air is delivered through neat vents. Wall-mounted units are also compact and unobtrusive. We can show you the options during your assessment.
Can I cover my whole home?
Yes. With a multi-split or ducted system you can cool and heat several rooms, or your whole home. We will recommend the right setup based on your rooms and how you use them.
