Multi Split Systems

Why Multi Split?

The ideal cooling/heating solution for each room with just a single outdoor unit.

A Multi Split System gives you the freedom to select the indoor model best suited to each room in your home and caters to your comfort without cluttering the exterior.

Enhancing aesthetics by reducing the number of outdoor units required.

With a Multi Split Air Conditioning Technology, you also get the benefit of enhanced efficiency and energy savings.

Multi-Split Air-Conditioning Systems are Ideal for:

Flat Roof Homes

Do you live in a house with a flat roof? This design style usually doesn’t accommodate the ducts associated with ducted solutions.

This smart choice connects up to 6 internal units to a single external hub.


No underfloor space

Along with flat roofs, we often encounter houses that don’t have enough underfloor space for a ducted system.

In such cases, we design and install a multi-split system that accounts for your family’s individual needs.


Double Story Homes

Double story homes are unique in that there is often no space to fit ductwork from the roof to the ground floor.

Multi-split air conditioning keeps your living area cool downstairs while entertaining, while upstairs sleeping kids can stay warm.

Limited outdoor space?

No problem – we can connect up to 6 indoor units to a single outdoor hub, which provides an excellent solution for maintaining outdoor aesthetics.

Individual Control

As each indoor unit has a controller, occupants in each room can adjust the temperature to their desired needs without worrying about affecting others in the home.


It’s an efficient way to deliver cool, fresh, and clean air to your home with individual and precise temperature control. The KW capacity can be matched to individual room sizes.

Inverter technology

Compressor inverter technology allows for the rapid cooling of isolated spaces. Once this has been achieved, only a small amount of power is needed to set temperature levels in each room.

Reverse cycle

Reverse cycle technology means you not only keep cool in the summer, but warm in winter, too! Enjoy year-round comfort, no matter the temperature outside.

Choice of indoor units

A Multi Split System is the perfect addition to any home, giving home owners the opportunity to select multiple indoor air conditioner models, with a different model in each room. The ability to incorporate a range of models within a single Multi Split System, ensures that the functional and aesthetic requirements of each room can be fulfilled.

Numerous indoor units

Individual indoor units operate independently, so every occupant of each room can set their desired temperature.

Although these units are commonly wall-mounted, they can also be installed within the ceiling cavity. There are many indoor solutions available, so you can choose the one that best suits your home’s aesthetics, easily installed by the experts at Alpha Air.

Single outdoor hub

The outdoor hub is discreetly located and housed within a sturdy cabinet to ensure its protection, while also allowing exhausted air to dissipate into the atmosphere.

It is attached to an existing structure or building and usually requires no extra elements or reinforcement. All that’s needed is a location for the distribution of clean air, a constant electrical power supply, and a stable footing base to avoid vibration.

System design

System design includes determining the most appropriate size and KW capacity for numerous rooms in the house. For example, a smaller bedroom may require less capacity than a larger living room.

The capacity required of all indoor units combined tells us what the outdoor unit’s KW capacity must be.

There are many factors used to determine the ideal capacity that’s needed for every room your multi-split system will power, including:

  • Orientation
  • Size
  • Thermal load
  • The location of doors and window
