Advanced multi-split systems represent a major advance on the original split system design. Previously, you required separate outdoor units for each indoor unit: however, a multi-split system can effectively cool or heat multiple rooms with multiple indoor units with just a single outdoor unit.
As with every other air conditioning system installation we carry out, we’ll first hold an initial consultation to understand your specific requirements and design a custom system that suits your needs.
• Multiple Rooms: Connect up to 5 indoor units to one outdoor unit
• Single Outdoor Unit: Space-saving design with one compressor unit
• Heats and Cools: Year-round climate control
• Energy Efficient: Intelligent power distribution reduces electricity costs
• Individual Control: Each room can be set to different temperatures
• Programmable Scheduling: Create comfortable environments when needed
For seamless room-to-room air conditioning solutions, exceptional climate control efficiency and complete customer satisfaction, we deliver comprehensive aircon multi split system installation services across Sydney. We specialise in creating tailored, comfortable environments for every space throughout your property, maximising energy efficiency and delivering the highest standards of workmanship backed by extensive after-sales support.
A multi-split air conditioner system, is a smart and efficient way to heat and cool your home. It connects multiple indoor units to a single outdoor compressor, allowing you to control the temperature in different rooms independently.
This setup reduces outdoor clutter, saves space, and gives you the flexibility to keep your living room cool and your bedroom cosy — all from one central control.

On time, friendly and professional
I would highly recommend Robert Air Conditioning company I needed a split system put in my elderly mothers home. I contacted Roberts and was amazed how efficient Monique and Mitchell were. On the day of installing Mitchell and his apprentice were very professional and polite after Mitchell was finished he explained to my elderly mother how to use the remote to her new air con now thats service thank you so much
Staff were friendly and helpful from the start. Good communication before install, serviceman was friendly and thorough, the job was a little more complicated than expected but he took it in his stride and still got it done the best he could - even took a call from my husband half way through the job to go over everything with him and answer questions. Mel followed up to make sure we were happy after install as well. Great communication, no complaints at all from me. Highly recommend! Thanks, Roberts air conditioning!
The process from quote to completion was excellent and painless. Everyone was professional and committed to doing the job well, not just getting it done.
The Roberts team were great and jumped in to help us with a very long drawn out repair when we were unable to get a response from the original installer. Monique was so helpful and responsive! On the day Jake the technician was on time (so rare these days!) and very polite. I would highly recommend the Roberts team. Thank you
All major brands available on request
Like wall-mounted split systems, floor and ceiling-mounted split systems are designed to provide air conditioning for individual rooms or targeted areas within your home or business.
The ideal choice for cooling and heating areas where a discreet installation is required. The indoor unit fits flush into the ceiling with only the supply and return grilles visible inside your home or office – leaving maximum floor and wall space for furniture, decoration and fittings.
Designed with discretion in mind, a large ducted air conditioning system seamlessly blends into your home or commercial space, delivering luxurious comfort without compromising on style. It’s a tailored solution that works perfectly for your unique needs.
What is the difference between a multi and an individual split system?
Multiple split system air conditioning offers several advantages, including energy efficiency, space saving, individual room control, and cost-effectiveness compared to multiple separate systems.
How many rooms can a multi-split system cool?
A single air conditioning outdoor unit can typically connect to up to five indoor units, making it ideal for multi-room applications.
Are multi-air conditioners suitable for large rooms?
Yes, multi-system AC for large rooms might be suitable with proper planning. You can install multiple indoor units in one large space for better air distribution. However, you need to consider some inportant factors such as room size, layout, airflow, capacity sharing. For very large commercial spaces or rooms over 700 sq ft, consider ducted systems or multiple units for optimal coverage.
Is a multi-system air conditioner energy efficient?
Yes, multi-split systems use intelligent energy distribution and modern inverter technology to minimise energy consumption while maintaining optimal comfort.
Can I control each room individually?
Absolutely. The multi room split system allows individual Room to Room air conditioners control. You can independently control each indoor unit with different temperature settings and programmable scheduling options.
What brands do you install?
We work with all major air conditioning brands and can recommend the best system for your specific needs and budget.
