Why Choose a GENERAL Multi System?

A traditional split system requires one outdoor unit for every indoor unit.

For homes needing air conditioning in multiple bedrooms and living spaces, this can quickly become impractical.

GENERAL Multi Systems solve this by connecting several indoor units to a single outdoor condenser.

Benefits include:

• One outdoor unit instead of several
• Independent temperature control in every room
• Energy-efficient inverter technology
• Flexible installation options
• Modern R32 refrigerant
• Reduced outdoor clutter
• Quiet operation
• Expandable room configurations
• Suitable for new homes and renovations

 

How Does a Multi System Work?

A GENERAL Multi System uses one outdoor compressor to power multiple indoor air conditioning units throughout your home.

Each indoor unit operates independently.

This means:

• One bedroom can be cooling.
• Another bedroom can be switched off.
• The living room can be heating.
• Every room has its own controller and preferred temperature.

Unlike ducted systems that condition zones, each indoor unit operates as an individual split system connected to the same outdoor unit.

 

Save Outdoor Space

One of the biggest advantages of a GENERAL Multi System is reducing the number of outdoor units installed around your home.

Instead of mounting four or five condensers along external walls, a single compact outdoor unit serves multiple rooms.

Benefits include:

• Cleaner exterior appearance
• More usable outdoor space
• Less visual impact
• Easier planning for smaller blocks
• Ideal for townhouses
• Perfect for apartments
• Better suited to homes with limited outdoor wall space

 

Individual Room Temperature Control

Every family uses rooms differently.

Children may prefer cooler bedrooms.

Parents may prefer warmer temperatures.

Guest rooms may rarely be used.

GENERAL Multi Systems allow each indoor unit to be individually controlled, giving complete flexibility throughout the home.

Advantages include:

• Personal comfort
• Lower running costs
• Only cool occupied rooms
• Independent schedules
• Greater energy efficiency

 

Extensive Indoor Unit Options

Unlike many systems that only offer wall-mounted units, GENERAL Multi Systems provide a wide variety of indoor styles to suit different rooms and architectural designs.

Available indoor unit options include:

Wall Mounted Units

The most popular option for bedrooms, studies and living rooms.

Bulkhead Units

Hidden within ceiling bulkheads for a discreet appearance.

Slimline Ducted Units

Ideal where concealed air distribution is preferred.

Compact Cassette Units

Installed flush into ceilings for unobtrusive comfort.

Floor Console Units

Perfect where wall space is limited or for replacing older heaters.

Ceiling Console Units

Designed for spaces where wall mounting isn't practical.

This flexibility allows Southern Stars to design a customised solution tailored to your home's layout.

 

Connect Between Two and Five Rooms

GENERAL offers several outdoor unit sizes capable of connecting different numbers of indoor units.

Configurations include:

Outdoor Unit	Indoor Units
Small Multi System	2–3 rooms
Medium Multi System	2–4 rooms
Large Multi System	2–5 rooms

This flexibility allows systems to grow with your home's requirements while maintaining efficient performance.

Energy Efficient R32 Technology

GENERAL Multi Systems utilise modern R32 refrigerant.

Benefits include:

• Improved efficiency
• Lower Global Warming Potential (GWP) than R410A
• Excellent heating performance
• Excellent cooling performance
• Modern environmentally conscious refrigerant technology.

Combined with inverter compressor technology, the system adjusts output according to demand to minimise unnecessary energy consumption.

 

Is a Multi System Better Than Ducted Air Conditioning?

It depends on your home.

A Multi System is ideal when:

• You don't need every room air conditioned.
• You want independent room control.
• Ceiling space is limited.
• You want fewer outdoor units.
• You are renovating one section of the home.

Ducted air conditioning is generally more suitable when:

• You want whole-home comfort.
• You prefer hidden indoor units.
• You're building a new home.
• You want centralised zoning throughout the house.

Southern Stars can help determine which solution best suits your property.
