The Daikin FDYA140AV19 / RZAS140C2V1 is a premium reverse cycle ducted system designed for large homes, open-plan living areas, and multi-room applications. As part of Daikin’s Premium Inverter range, it delivers stronger energy efficiency, quieter operation, and greater installation flexibility than the standard FDYAN series while remaining concealed within the ceiling space.
With 14.0kW cooling and 16.5kW heating capacity, this model is ideal for larger family homes, 4–5 bedroom properties, and open-plan spaces around 80–120m² depending on insulation and layout. The inverter compressor can modulate output from 5.0kW up to 16.0kW in cooling mode and from 5.1kW up to 18.0kW in heating mode, helping maintain stable indoor temperatures and reduce running costs.
Key Features & Benefits
Premium Inverter Technology
Daikin’s Premium Inverter range uses a redesigned cross-pass heat exchanger, DC fan motor, and improved refrigerant control to deliver stronger seasonal efficiency, smoother temperature control, and quieter performance than standard ducted systems.
Improved Energy Efficiency
The system delivers an EER of 3.56 and COP of 3.86, with residential TCSPF ratings up to 5.00 in hot climates. This helps reduce ongoing energy use and running costs compared to conventional or fixed-speed systems.
Compact Indoor Unit Design
The indoor unit measures approximately 400mm high, 1505mm wide, and 980mm deep, while the outdoor unit measures around 1430mm high, 940mm wide, and 320mm deep. Despite its large capacity, the system is designed to suit many modern homes with limited roof space.
Strong Airflow Performance
The unit provides rated airflow of approximately 900 litres per second, with maximum airflow up to 1000 litres per second. This helps deliver even conditioned air across multiple rooms and larger open-plan spaces. Indoor sound levels are approximately 45.9dBA in cooling mode and 47.4dBA in heating mode.
Long Pipe Run Capability
The Premium series supports refrigerant pipe lengths up to 75 metres, giving installers greater flexibility for larger homes, multi-storey properties, and more complex ducted layouts.
Night Quiet Mode
Daikin’s Night Quiet Mode automatically reduces outdoor operating noise during sleeping hours and resumes normal operation in the morning, helping minimise disturbance to occupants and neighbours.
R22 Retrofit Capability
This model supports R22 retrofit applications, allowing existing pipework to often be reused when replacing older systems. This can help reduce installation time and overall project cost.
R32 Refrigerant
The system uses modern R32 refrigerant for improved efficiency and lower environmental impact compared to older refrigerants. Daikin uses R32 across its Premium Ducted range from 7.1kW to 16.0kW capacities.
Single-Phase Power Supply
This model operates on standard 220–240V single-phase power, making it suitable for most residential homes without requiring 3-phase power.
Wired Controller Included
The system is commonly supplied with Daikin’s BRC1E63 wired wall controller, providing simple scheduling, temperature control, and system management.
5-Year Manufacturer Warranty
Daikin ducted systems are backed by a 5-year manufacturer warranty for residential applications when professionally installed and maintained.
Ideal Applications
- 4–5 bedroom homes
- Open-plan living areas
