Split System Air Conditioning Perth
Split system air conditioning gives you fast, affordable heating and cooling for a single room or open plan space, with a slim indoor unit on the wall and a compact unit outside. Advanced Air WA supplies and installs split systems across Perth, sized properly for the room, installed cleanly by licensed technicians, and backed by a 5 year warranty on components and units.
How Split Systems Work
A split system is two connected units. The indoor unit sits high on the wall and delivers conditioned air into the room. The outdoor unit handles the heat exchange. Nearly all modern split systems are reverse cycle, so the same unit cools in summer and heats in winter, with inverter technology that adjusts output smoothly to hold your set temperature without chewing power.
Where Split Systems Shine
- Bedrooms. Quiet overnight comfort without conditioning the whole house. Sleep modes on modern units are near silent.
- Living areas. A properly sized unit will comfortably handle an open plan kitchen and living zone.
- Home offices. Working from home through a Perth summer without one is rough.
- Additions, granny flats and garages. Spaces the existing system does not reach.
- Rentals and budget conscious upgrades. Comfort where you need it most, without the outlay of a whole home system.
Need most of the house covered? A ducted system is usually better value across four or more rooms. Our types of air con page compares the options.
Getting the Size Right
Sizing matters more than brand. An undersized unit runs flat out on a 40 degree day and still loses; an oversized unit short cycles, wastes power and dehumidifies poorly. As a rough Perth guide:
- Small bedroom (up to 20 square metres): 2.5 kW
- Large bedroom or office (20 to 30 square metres): 3.5 kW
- Living area (30 to 45 square metres): 5 to 6 kW
- Large open plan (45 to 60 square metres): 7 to 8 kW
Ceiling height, insulation, and west facing windows all push the number up. We confirm sizing at quote stage so you get the right unit, not the nearest one on the shelf.
Quality Brands, Tidy Installs
We supply and install split systems from Daikin, Panasonic, Mitsubishi Heavy Industries and Fujitsu General, chosen for reliability and warranty support in Australia. Every install is done by our own licensed technicians (RTA AU46880 for refrigerant, EW 193940 for electrical), with pipework run neatly, the outdoor unit positioned for airflow and noise, and the wall penetration sealed properly. It is a half day job done once, done right.
Once your split is in, we look after it too. Our air conditioning maintenance is available for systems we have installed and for new systems, so your unit keeps running cleanly and efficiently year after year.
Multi Head Split Systems
Short on outdoor space? A multi head system runs two or more indoor units from a single outdoor unit. It suits apartments, townhouses and homes where councils or strata limit outdoor units. We will tell you honestly when a multi head makes sense and when separate systems or ducted is the smarter buy.
Frequently Asked Questions
How much does a split system cost installed in Perth?
A split system supplied and installed in Perth typically costs $1,200 to $3,500 depending on capacity and brand. Larger 7 to 8 kW units for open plan areas sit at the top of that range. Advanced Air WA quotes a fixed installed price upfront.
What size split system do I need for a bedroom?
A standard Perth bedroom up to 20 square metres needs about a 2.5 kW split system. Larger bedrooms or rooms with west facing windows usually need 3.5 kW. Correct sizing keeps the unit quiet and cheap to run.
How long does split system installation take?
A standard back to back installation, where the indoor and outdoor units share a wall, takes about half a day. Longer pipe runs or difficult access can extend it to a full day.
How much does a split system cost to run?
A modern inverter split system costs roughly 25 to 80 cents per hour in Perth depending on size and settings. Reverse cycle heating in winter costs about the same, far less than a portable electric heater.
Do split systems heat as well as cool?
Yes. Almost all split systems sold in Australia are reverse cycle, which means they heat in winter and cool in summer. Reverse cycle heating is one of the cheapest ways to heat a room in Perth.
