How it works
The right system,
in the right spot.
A split system is the simplest way to make one room genuinely comfortable — a slim indoor unit paired with an outdoor condenser, giving you both cooling in summer and heating in winter.
Sizing and placement matter more than brand. We look at the room size, ceiling height, windows, sun exposure and how you use the space, then recommend a capacity that runs efficiently instead of struggling or short-cycling.
Installation is done neatly: tidy pipework, clean penetrations, correct drainage and a proper commissioning check before we leave.

FAQs
Common questions.
What size split system do I need?
It comes down to the room's size, ceiling height, insulation, window area and orientation. We assess the space before quoting so the system isn't undersized or oversized.
Can a split system heat as well as cool?
Yes — modern reverse-cycle split systems are one of the most efficient ways to heat a room in a Sydney winter.
Can you install a split system in more than one room?
Yes. Either separate single systems or a multi-head system running several indoor units from one outdoor unit, depending on your layout.
How long does installation take?
A straightforward single split system is usually completed in a day. We confirm the timing when we quote your job.
