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 Hills District, North Shore and 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.

    It was a pleasant experience from go to whoa.

    Arran listened to all our requirements and concerns and came up with a suggested system that fitted our needs.

    His team arrived punctually on the day and installed it within the day,

    No problems or hassles, even cleaned up all the dust, packaging, and took the old system and rubbish with them.

    The new system was commissioned and working better than we had hoped for.

    Many thanks to Arran and his team for a job well done.

He gave us extremely competitive quotes and his team was professional on the day of installation. You will not regret using Maxim Air Conditioning! Will definitely use them again in the future.

    The guys from Maxim were really great. Our installation was a bit complicated and Arran spent a lot of time with us scoping the job to make sure everything was covered. He then presented us with options to make sure we got the best solution possible. On the day, the team of Stephen, Victor, Matt, Sam and Hamid did a really professional job. They were careful, the standard of work was excellent and they did a great job cleaning up afterwards. I would happily recommend Maxim to anyone looking for a quality air conditioning team.

    Great experience from start to finish. Arran was very professional over the phone and very informative about the products available and the whole installation process. He also made a follow up call to check on the installation and service provided. The 2 installation guys were also very friendly and professional and did a great job with the our Mitsubishi reverse split system install and even fixed some ducting on our existing ducted system. Best service we've had so far from any company during our renovations. Thanks guys!

    Just had a ducted system and a single unit installed by Maxim. The "whole journey" was an exceptional experience! - very approachable, competitive and reasonable pricing, accommodating to installation date, friendly staff including the owners, who are down to earth people.

    No need to look elsewhere!
