Multi Head Split System Air Conditioners

Do you want to save on your cooling costs? If you've got a larger house, keeping every room comfortable through summer can be the biggest drain on your electricity bill. One way to beat the heat without breaking the bank is multi‑head split system air conditioning — a single outdoor unit that cools every room in your home.

One outdoor unit · every room covered
1

Individual control

Each unit operates independently, so you can set your desired temperature in every room — easy to run from remote controls or automated timers.

2

Accurate temperatures

Every indoor unit carries its own temperature sensor for precise readings, meaning faster and more efficient cooling.

3

Quiet operation

Fewer outdoor units means less noise outside your home. Indoor heads are engineered for whisper‑quiet running, even in bedrooms and studies.

4

Saving money

Only cool the areas you actually use. We'll help you choose the right size heads for optimal cooling in every room.

5

Saving space

A single outdoor unit takes up less space and has far less visual impact on your home than multiple separate systems.

6

Cleaner air

Most split systems filter the air as they cool it, removing dust, allergens and other impurities for healthier indoor air.

7

Low maintenance

Multi‑split systems are easy to live with — just clean the filters regularly. Every install is backed by manufacturer warranty.

How does it work?

Split system air conditioners separate the indoor fan coil unit from the outdoor compressor, giving you more flexibility to choose where these components are located. Multi-head split systems are even more convenient, as they only require a single compressor to power as many indoor units as you need.

These systems filter and recycle the air in the room, the air is then cooled as it passes over an evaporator coil and gets blown around the room by fans, heat removed from the internal space is then transferred outside the building through the outdoor condenser unit. If you choose a reverse cycle air conditioner, the cooling process can be put in reverse to provide energy-efficient heating in the winter.

However, unlike other air conditioning systems, multiple indoor units may be connected to a single compressor to save space outside. A multi-head split system can also provide both cooling and heating if you choose a reverse cycle air conditioner.

Multi-split systems take up less space than ducted systems, and they're also preferable if you have a flat roof or live in a humid climate. If your multi-head system has the capacity for more heads than you're currently using, these can be added later on as you need them. However, single-head split systems can't be converted into multi systems.

MaXim Air is great. My ducted aircorn was showing an erroe code after running for 10 mins or so each time. MaXim aircorn came, identified problem accurately, provide all options, no hard sale technique to push customer to replace the aircorn unit, on the contrary, they assess the problem and offered best and more economical way to resolve the issue. They serviced my aircor outdoor unit, raising the foundation structure, cleaned the vent, sealed old cables. The aircorn is working again. MaXim Air endeavoured to fit me in and come punctually, did an absolutely good job. Highly recommended.

We had our ducted AC replaced by MaximAir and they did an excellent job. Stephen conducted a site visit, inspected our ducts and provided us with a good, detailed explanation of the options. We selected an airtouch 4 system with 8 zones, all individually temperature controlled and we are really happy with it. Arran gave us a competitive quote and Victor and his team did an amazing job on the installation day. The crew arrived on time, were polite and tidy. Overall, we are very happy with the service we got from MaximAir.
