The Daikin FDYAN125AV1 is a 12.5kW single-phase inverter ducted system with 15.0kW of heating — large-home capacity that still runs on a standard single-phase supply, which is often the deciding factor.
Coalfields Climate Control designs, supplies and installs ducted systems across Singleton and the Hunter Valley.
Overview of Daikin 12.5kW Inverter Ducted Reverse Cycle System (FDYAN125AV1)
▾The FDYAN125AV1 pairs with the RZA125CV1 outdoor unit. Rated capacity is 12.5kW cooling and 15.0kW heating, modulating from 4.0kW to 14.0kW in cooling.
This is where the indoor unit steps up to the larger chassis: 360 x 1520 x 935 mm at 55kg. At 360mm high and over 1.5m long, it needs genuine ceiling space and a viable access path to get it up there. That is a real constraint in older homes and one of the first things we check on site — it is far better to find out at assessment stage than on installation day.
Airflow is 755 l/s nominal, 840 l/s maximum. The outdoor unit stays at 990 x 940 x 320 mm but rises to 78kg.
Refrigerant is R32, on a 50m maximum pipe run.
– 15.0kW heating output for large homes in Hunter Valley winters
– Still single-phase — no three-phase supply required at 12.5kW
– 755 l/s nominal airflow for extensive duct networks
– Zoning compatible for room-by-room control
– Inverter modulation from 4.0kW to 14.0kW in cooling
– R32 refrigerant
– 50m maximum pipe run
– 5-year parts and labour warranty when professionally installed
Is the Daikin 12.5kW Inverter Ducted Reverse Cycle System (FDYAN125AV1) right for your home?
▾– Large homes, roughly 150 to 230 m2 of conditioned floor area
– Two-storey homes with substantial glazing
– Homes with high ceilings where air volume exceeds what floor area implies
– Properties wanting large capacity without the cost of a three-phase upgrade
– Light commercial premises on a single-phase supply
Check ceiling space early. The 360mm-high chassis will not fit every roof, and if it does not, the conversation changes to multiple smaller systems or a different plant location.

Energy Efficiency & Performance
▾The FDYAN125AV1 is rated at 3.17 EER cooling and 3.75 COP heating. Seasonal figures under GEMS 2019 are a TCSPF of 4.26 / 3.91 / 4.02 and HSPF of 4.31 / 3.31 / 2.77.
Its average-zone TCSPF of 3.91 is the highest in the entire FDYAN range — better seasonal cooling efficiency than any of the smaller units. For a large Singleton home that runs cooling hard through summer, that is a meaningful advantage over a season, even though its single-point EER of 3.17 looks unremarkable.
Rated input is 3.94kW cooling and 4.00kW heating. At that draw on single-phase, switchboard and circuit capacity must be confirmed before the system is specified — not after.
The heating HSPF drops sharply in the cold zone (2.77) but Singleton sits in the average zone, where it reads 3.31.
Installation Notes for the Daikin 12.5kW Inverter Ducted Reverse Cycle System (FDYAN125AV1)
▾This system pairs the FDYAN125AV1 indoor unit with the RZA125CV1 outdoor unit, on a 240V single-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 FDYAN125AV1 suit?
Roughly 150 to 230 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?
It runs on a standard 240V single-phase supply, so most homes will not need a supply upgrade. We still check switchboard and circuit capacity during the assessment, because a system this size adds a substantial load alongside everything else in the house.
Will the indoor unit fit in my roof space?
The indoor unit is 360mm high and 1520mm 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?
R32, which has a lower global warming potential than the older R410A and costs less to top up if the system ever needs a regas. Daikin requires R32 ducted indoor units to be installed in the ceiling space, not under floor.
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.
