The Daikin FDYQN200LCV1 is a 19.5kW three-phase inverter ducted system with 22.4kW of heating, for large homes and commercial premises across the Singleton district.
Note the capacity: rated cooling is 19.5kW, not the 20.0kW the model number implies. Coalfields Climate Control sizes from measured heat load and the real published figures.
Overview of Daikin 19.5kW Inverter Ducted Reverse Cycle System, Three Phase (FDYQN200LCV1)
▾The FDYQN200LCV1 pairs with the RZQ200MY1 outdoor unit on 415V three-phase supply. Rated capacity is 19.5kW cooling and 22.4kW heating, modulating from 10.1kW to 19.5kW in cooling.
Airflow jumps to 1400 l/s nominal and 1600 l/s maximum — a substantial increase over the 180 model and the practical reason to choose this size, since it allows longer duct runs and more zones without starving the far end of the system.
The indoor unit is 470 x 1400 x 997 mm at 85kg. The outdoor unit is 1680 x 930 x 765 mm at 138kg, the same as the 180 model. Like the rest of the FDYQN range it uses a scroll compressor and R410A refrigerant, with brazed 9.5mm liquid and 19.1mm gas connections.
Outdoor sound pressure is 58 dB(A) cooling and 59 dB(A) heating at one metre, EPA sound power 74 dBA.
– 19.5kW cooling and 22.4kW heating on 415V three-phase supply
– 1400 l/s nominal airflow, 1600 l/s maximum — significant headroom for multi-zone layouts
– Hermetically sealed scroll compressor
– Zoning compatible across multiple distinct areas
– Brazed pipe connections
– 50m maximum pipe run
– 5-year parts and labour warranty when professionally installed in domestic premises
Is the Daikin 19.5kW Inverter Ducted Reverse Cycle System, Three Phase (FDYQN200LCV1) right for your home?
▾– Very large homes, roughly 260 to 380 m2 of conditioned floor area
– Commercial premises — offices, clinics, function spaces, retail
– Multi-zone installations where several areas run on different schedules
– Buildings with long duct runs where airflow headroom matters more than raw capacity
– Properties with existing three-phase supply
The airflow headroom over the 180 model is often the deciding factor rather than the extra 1.5kW of capacity. If your duct network is extensive, that matters more than the capacity difference.

Three-phase supply required -- confirm available before specifying. Indoor unit 470mm high; check ceiling space. Brazed pipe connections: 9.5mm liquid, 19.1mm gas. Drain BSP 3/4 inch internal thread. Hermetically sealed scroll compressor. Outdoor operating range -5 to 43 degrees C DB cooling, -20 to 16 degrees C WB heating.
Refrigerant & Environment
▾Refrigerant
R410A
This range uses R410A rather than the R32 used across the single-phase FDYAN range. R410A has a higher global warming potential and a different service and top-up cost profile -- worth factoring into whole-of-life cost.

Energy Efficiency & Performance
▾The FDYQN200LCV1 is rated at 3.19 EER cooling and 3.27 COP heating — slightly better cooling efficiency than the smaller 180 model at 3.09 EER. Seasonal figures under GEMS 2019 are a TCSPF of 3.57 / 3.14 / 3.11 and HSPF of 3.25 / 2.97 / 2.63.
Rated input is 6.11kW cooling and 6.85kW heating across three phases.
As with the rest of this range, seasonal efficiency sits below the single-phase FDYAN units. Three-phase systems at this capacity are chosen because the load demands them, not because they are more efficient. Where a job could be served by either, the comparison is worth running properly.
R410A refrigerant applies here as across the FDYQN range, with the higher top-up cost and global warming potential that comes with it.
Installation Notes for the Daikin 19.5kW Inverter Ducted Reverse Cycle System, Three Phase (FDYQN200LCV1)
▾This system pairs the FDYQN200LCV1 indoor unit with the RZQ200MY1 outdoor unit, on a 415V three-phase supply, with a maximum pipe run of 50m.
A ducted system is a building job as much as an equipment job. Before quoting, Coalfields Climate Control assesses ceiling space and access, plans the zone layout and duct runs, calculates the heat load room by room, checks the electrical supply, and confirms where the outdoor unit can sit without creating a noise problem at a boundary.
What supply and install through us covers:
– Manufacturer-approved installation by qualified technicians, so the warranty is not compromised by a non-compliant install
– A lifetime guarantee of workmanship on the installation itself
– A 10-day install guarantee on split system installations in Singleton
– Drop sheets laid before work starts, mess cleaned up afterwards, and a walkthrough of how to operate the system
The most common problem we are called out to fix is not a faulty unit — it is an installation issue: undersized selection, poor outdoor unit placement, or drainage that was never set up properly. Getting the supply and the install from one local team means one number to call if anything is not right.
To arrange a site assessment and quote, call 0422 493 102.
Warranty Information
▾Daikin provides a 5-year parts and labour warranty on ducted systems professionally installed in domestic premises in Australia.
That warranty depends on the installation being carried out correctly by a qualified installer, and on normal use and maintenance. A DIY or unlicensed install is the fastest way to void it — and handling refrigerant without a licence is an offence in Australia regardless of the warranty position.
Coalfields Climate Control installs to manufacturer specification and is manufacturer-approved for full warranty servicing across all major brands, so ongoing servicing can be handled locally rather than through a metropolitan agent. Our own workmanship carries a lifetime guarantee on top of the product warranty.
Warranty coverage depends on correct installation, normal use, maintenance requirements and the manufacturer current warranty terms.
Frequently Asked Questions
▾What size home does the FDYQN200LCV1 suit?
Roughly 260 to 380 m2 of conditioned floor area. Floor area is only a rough guide though -- ceiling height, insulation, glazing and orientation change the answer significantly. We do a room-by-room heat-load calculation on site before quoting a ducted system.
Do I need a three-phase power supply?
This model needs a 415V three-phase supply. Many Singleton homes have single-phase only, and bringing three phase to a property is a significant separate cost. We confirm what your property actually has as part of the site assessment -- before you commit to anything.
Will the indoor unit fit in my roof space?
The indoor unit is 470mm high and 1400mm long, and it has to be lifted into position as well as fitted. Ceiling space and access route are among the first things we check on site -- it is far better to find a problem at assessment stage than on installation day.
What refrigerant does it use?
This model uses R410A. The single-phase FDYAN range uses R32, which has a lower global warming potential and costs less to top up. On a system with this much charge that difference is worth understanding before you commit, so we raise it at quoting stage rather than after.
How much does a ducted system cost to install in Singleton?
Ducted pricing depends on the number of zones, duct runs, ceiling access, electrical work and where the outdoor unit can go -- far more variable than a split system. We quote after a full site assessment and heat-load calculation. Call 0422 493 102 to arrange one.
Does zoning actually save money?
Yes, and it is the single biggest lever on running cost. Conditioning three rooms instead of seven cuts consumption roughly proportionally. Getting the zone plan right at design stage matters more to your bills than small differences in equipment efficiency ratings.
