If you're looking for the ultimate air conditioning solution for a large commercial building or home, they don't come better than VRF systems.

Also known as VRV air conditioners, these split systems only require a single outdoor unit that connects to as many indoor units as you need, without the need for bulky and rigid ducts. installation.

Individual zone controls give you total flexibility in setting your desired temperatures in multiple areas. Inverter technology makes VRF systems some of the most energy-efficient air conditioners on the market, helping to keep your energy costs as low as possible while enjoying comfortable temperatures all year round.

Maxim Air designs, supplies, installs and services VRV & VRF air conditioning in all Sydney metropolitan areas. Get in touch to arrange your obligation-free consultation with our highly experienced engineers today.


What's the difference between VRV and VRF air conditioning?

The terms VRV and VRF both refer to the same HVAC technology. The difference is that VRV (variable refrigerant volume) was the original technology and is a registered trademark of Daikin Industries. All other manufacturers use the term VRF (variable refrigerant flow).

What is a VRV system?

Daikin VRV air conditioning was first launched in 1982 and is still produced today. It was the first HVAC system to use variable refrigerant flow controls, offering more precise control over temperatures than standard cooling systems.

Daikin VRV systems are especially popular in medium to large commercial buildings or other large properties that require a flexible and efficient cooling solution.

What is a VRF system?

All variable refrigerant systems not produced by Daikin are known as VRF air conditioners, which is the vast majority of systems. These work on the same principles as VRV, but there's a much wider range of options to choose from across different brands and models.

VRF systems use refrigerant for cooling rather than water, with DC inverters controlling motor speeds and refrigerant flow to minimise power consumption. Many systems are designed to be expandable, allowing more units to be added over time in a growing business or project.

How do they work?

VRV and VRF are multi split systems with multiple indoor units connected to a single outdoor unit incorporating one or more compressors. These units are connected by refrigerant piping and communication wiring in a closed loop.

Each indoor unit can be independently controlled, either using a wired control panel or remotely. When a user activates an indoor unit and sets their desired temperature, the system responds by checking the indoor and outdoor conditions. It then delivers the precise amount of refrigerant needed to reach the optimal indoor temperature.

The system constantly monitors and responds to changing ambient temperatures to keep power consumption at a minimum and maintain consistent temperatures. Many VRF systems can provide both cooling and heating.

What are the benefits of VRF air conditioning?

VRF systems are some of the most advanced air conditioners available. They offer distinct advantages over most other systems for larger buildings or projects.

  • Save energy – VRF compressors feature DC inverters that control motor speeds and refrigerant flow with greater precision, allowing for partial load use. Because no ducting is used, VRF avoids the energy loss of ducted systems.
  • Improve comfort – VRF systems continually monitor ambient conditions and adjust the refrigerant flow to maintain consistent temperatures.
  • Total control – Each indoor unit has individual climate controls, offering precise control over internal temperatures in multiple areas. Many systems can be integrated with home automation and building management systems.
  • Fully customisable – The modular design of VRF systems offers greater flexibility for buildings and projects of varying sizes. The system can be expanded when needed by adding more indoor units up to its maximum capacity.
  • Ease of installation – VRF systems don't necessarily need to use ducting, which makes them quicker and cheaper to install. Their modular design means they can be installed in stages as needed.


What types of VRF systems are there?

There are several types of VRF air conditioners to choose from, depending on your needs. These are:

  • Heat pump systems – providing all cooling or all heating across all climate zones.
  • Heat recovery systems – heating and cooling may be used simultaneously in different zones.
  • Cooling only systems – if you live in a warmer climate and don't require heating.

    The team at MaXim Air are extremely professional and friendly. They provided expert advice and suggestions during the initial quote for a ducted system, which was also highly competitive. The installation went flawlessly, they even helped fix up a sagging ceiling when installing the ducted vents. They truly went above and beyond in making sure I was 100% happy with the job. I would highly recommend MaXim Air Conditioning.

    Arran provided expert advice and ideas (that no one else had suggested) for the initial quote for our ducted air conditioning. The quote was very competitive. We received reminders of the installation day via text prior to installation. On the day of installation Victor and his team arrived on the dot of 7am and worked all day until the job was completed. They were very conscientious and cleaned up thouroughly. Would highly recommend MaXim air conditioning services.

    Maxim recently installed 2 split system air conditioners for us and we were very pleased with their excellent service. Stephen and his team were efficient, hardworking, professional, and pleasant to deal with. We were impressed with the effort that the team went to in ensuring we were happy with the position of the units in each room, and making sure the areas were tidy and all rubbish removed after installation. The team was punctual and completed the tasks within the quoted time frame. We also were grateful for the quick responses to our queries. We would highly recommend Maxim. Thank you Stephen and team.

    Excellent service from the Maxim team. A bit late (due at 7am which is too early on a Saturday anyway!) but no concern as they did a great job and were very helpful. Highly recommended.

    I had several companies quote to replaced my existing, very old, ducted system. Maxim was the only company to actually listen to what I wanted and make great suggestions - and they delivered a quote that was much lower than I had expected. They turned up on the agreed day and worked till the job was done - no corners were cut - the quality of the install was excellent. It was a very large complex job. They cleaned up everywhere - it was like they had never been there. They left very late at night, after a very early start. Before they left I found them with a torch going over my driveway in detail to make sure no screws had been left that i would drive over - you don't see that attention to detail often. The large team we had working at our place were all very courteous and friendly. For value, integrity and a very high standard or workmanship - I would recommend Maxim to anyone without hesitation.

    Stephen provided a detailed explanation of the installation process. Air con installed 1 month ago, with new duct, motor and unit. So far so good. The customer service was good, and the price reasonable.

    Maxim did a great job installing ducted aircon into my new house. The guys were very professional and offered good practical solutions compared to others who looked at the job. I would definitely recommend them to friends and use them again.
