Common questions about the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA

How much does the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA cost installed?

Quoted per home fully installed by our ARCtick licensed team, including standard installation materials, electrical connection and commissioning, backed by the Fujitsu 5-year manufacturer warranty and our 2-year installation warranty. Supply-only is $4,344. Our instant quote calculator confirms the installed price for your home from your address.

What room size does the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA suit?

It is rated for rooms up to 120 m², making it a strong fit for large whole homes. We confirm sizing against the room, insulation and sun exposure before installing, because right-sizing is what keeps running costs down.

How quiet is the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA?

The indoor unit runs at 34 – 44 dB(A). At the bottom of that range it is quieter than a whispered conversation, which is why we size systems to spend most of their time on low fan.

How much does the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA cost to run?

At a typical Sydney electricity rate, running at its full rated capacity costs approximately $1.15 to $1.30 per hour. Real-world costs are usually lower once the home reaches temperature, and lower again when only the day or night zones are running, because an inverter throttles right back. Peak tariffs, extreme weather, insulation, thermostat settings and system sizing can all move the number.

What warranty does the Fujitsu 12.5kW Inverter Ducted Air Conditioner System High Static SET-ARTH45KHTA come with?

A 5-year Fujitsu manufacturer warranty on the unit, plus a minimum 2-year warranty on our installation workmanship. We register the manufacturer warranty at commissioning, and ARCtick licensed installation is what keeps it valid.
