In the harsh Australian climate, choosing the right air conditioning system is essential for your home’s liveability and energy efficiency. Daikin, with over 45 years of experience in Australia, offers a comprehensive range of ducted reverse cycle systems designed specifically for our unique conditions.
From premium models with advanced zoning capabilities to compact designs for homes with limited space, Daikin provides options to suit various requirements and budgets.
This guide explores the differences between Daikin’s ducted reverse cycle units, comparing their features, efficiency, and suitability for different home types to help you make an informed decision for your cooling and heating needs.
A ducted air conditioning system provides whole-home comfort through a central unit that distributes air via a network of ducts. Unlike split systems with visible wall-mounted units, ducted systems are largely concealed, with only the controller, return air, and discharge grilles visible inside your home. This creates a seamless, aesthetically pleasing solution that maintains a consistent temperature throughout your living spaces.
Reverse cycle technology enables a single system to both heat and cool your home. By simply reversing the refrigeration cycle, these systems extract heat from outside air during winter and remove heat from indoor air during summer. This dual functionality eliminates the need for separate heating and cooling systems, providing year-round comfort from a single installation.
Modern reverse cycle ducted systems do more than just regulate temperature—they also filter and dehumidify the air, improving indoor air quality and creating a healthier home environment. This comprehensive approach to climate control makes reverse cycle ducted systems particularly popular among Australian homeowners looking for complete solutions.
Looking for ducted gas heating for your home in Blackburn, Fawkner, or Greenvale? Absolute Airflow offers affordable supply and installation of quality ducted systems. Our team is fully qualified and has extensive experience with a variety of brands and manufacturers.
With more than 45 years operating in Australia, Daikin has established itself as a leader in air conditioning technology specifically designed for our climate extremes. Recently awarded Australia’s Most Trusted Brand for Air Conditioners, Daikin manufactures many of their indoor units locally to Australian standards. This local manufacturing focus means their systems are built to withstand our harsher summer conditions and provide reliable performance year after year.
All Daikin air conditioners exceed Minimum Energy Performance Standards (MEPS), reflecting their commitment to energy efficiency—a critical consideration for Australian homeowners facing rising energy costs. Backed by a 5-year parts and labour warranty, Daikin products offer peace of mind along with premium performance.
Daikin offers four main ducted reverse cycle ranges, each designed to address different home requirements and installation scenarios:
The flagship series in Daikin’s ducted lineup, the Premium Inverter range combines superior energy performance with flexibility and R22 retrofit capability. These units feature:
The Premium Inverter series, including models like the FDYQ250LC-TY (24kW), is ideal for large homes or commercial applications requiring substantial cooling and heating power. The R22 retrofit capability makes these systems a cost-effective upgrade option for homeowners with older ducted systems, allowing them to reuse existing piping.
Engineered to deliver a compact and efficient design, the Inverter series is perfect for installation in the tight roof spaces common in modern homes.
Key features include:
Models like the FDYAN160A-CV (15.5kW) showcase this series’ balance of power and compact design, making it suitable for medium to large homes with space constraints.
Designed specifically for narrow ceiling spaces, the Slim-Line series offers a solution for homes where installation space is at a premium. These units maintain Daikin’s commitment to efficiency and performance while accommodating architectural limitations that might otherwise make ducted systems impractical.
For homeowners seeking the most discreet installation possible, the Bulkhead System is engineered for minimal visual impact. Particularly suited to drop ceilings or shallow ceiling spaces, these systems deliver Daikin’s performance while virtually disappearing into your home’s architecture.
All Daikin systems feature inverter technology, which works “like the accelerator of a car,” gently increasing or decreasing power as needed. This approach allows systems to reach desired temperatures quicker and maintain them without the energy-wasting fluctuations common in non-inverter systems.
The Premium Inverter series leads in efficiency with its industry-leading energy performance, while the standard Inverter series also offers excellent efficiency through improved component design. This focus on energy performance translates directly to lower running costs—particularly important in Australia where air conditioning can account for a significant portion of household energy consumption.
Zoning functionality is available across Daikin’s ducted range, allowing you to group rooms into specific “zones” that can be controlled independently. For example, you might assign bedrooms to Zone One and living areas to Zone Two, enabling targeted cooling or heating only when and where needed.
This selective approach to climate control delivers two significant benefits:
The Daikin Zone Controller makes this functionality accessible and user-friendly, helping maximise both comfort and cost savings.
Noise consideration is important for any air conditioning system, particularly in bedrooms and living areas. Daikin’s ducted systems feature impressive sound dampening technology, with indoor sound levels ranging from approximately 46-50 dBA depending on the model.
The Night Quiet Mode available in the Inverter series is particularly noteworthy, automatically reducing out. This thoughtful feature enhances sleep quality without compromising on climate control.
Daikin uses two primary refrigerant types across their ducted range:
Both refrigerants represent significant improvements over older R22 systems in terms of environmental impact and energy efficiency. The Premium Inverter series’ R22 retrofit capability provides an environmentally responsible path for upgrading older systems while minimising waste.
Selecting the appropriately sized system is critical for both comfort and efficiency. Undersized units will struggle to reach desired temperatures in extreme weather, while oversized units may cycle too frequently, wasting energy and creating temperature fluctuations.
As a general guide:
However, proper sizing requires consideration of multiple factors beyond floor area, including ceiling height, insulation quality, window placement, and local climate. Professional assessment is strongly recommended for accurate sizing.
Different Daikin models have varying installation requirements that may influence your choice:
The outdoor unit placement also warrants consideration, with side discharge units in the Inverter series offering more flexible placement options for models up to 19.5kW.
Homes with open floor plans may benefit from the uniform distribution of air that ducted systems provide. However, if your home has distinctly separated areas with different usage patterns (e.g., day vs. night zones), ensuring your chosen model supports effective zoning becomes particularly important.
All Daikin ducted systems support zoning, but the implementation may vary between models. Discussing your specific layout and usage patterns with an air conditioning specialist will help identify the optimal zoning strategy for your home.
Ducted systems represent a more significant initial investment compared to split systems but offer several long-term advantages:
The Premium Inverter series sits at the higher end of the price spectrum, with models like the FDYQ250LC-TY retailing around $9,470 (excluding installation). The Standard Inverter series offers a more moderate price point while still delivering excellent performance and features.
While initial costs are important, calculating the total cost of ownership over the system’s lifespan (typically 10-15 years) provides a more complete picture. Daikin’s emphasis on energy efficiency and durability contributes to long-term value despite the higher upfront investment.

For new homes, the Standard Inverter series often provides the ideal balance of performance, efficiency, and value. With models available from 5.0kW to 23.5kW, this series can accommodate virtually any new home size. The compact design integrates well with modern construction methods that often prioritise space efficiency.
The Premium Inverter series with R22 retrofit capability offers particular advantages for homeowners upgrading from older ducted systems. The ability to reuse existing piping can significantly reduce installation costs and complexity, making this series a cost-effective upgrade path.
For homes with limited roof cavity space, the Slim-Line or Bulkhead systems provide solutions where standard ducted units simply won’t fit. These specialised options ensure that architectural constraints don’t prevent you from enjoying the benefits of ducted air conditioning.
Larger homes or those requiring extensive zoning capabilities benefit from the Premium Inverter series’ superior capacity and performance. With models like the 24kW FDYQ250LC-TY offering wide operating ranges (cooling at -5 to 49°C and heating at -20 to 16°C), these systems deliver consistent comfort even in extreme conditions.
Choosing the right Daikin ducted reverse cycle system involves balancing several factors:
Daikin’s comprehensive range ensures there’s a system to match virtually any Australian home’s requirements. From the premium performance of the FDYQ series to the space-efficient design of the FDYAN models, Daikin’s commitment to quality, efficiency, and reliability remains consistent across their lineup.
