Common questions about the Fujitsu SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32

How much does the Fujitsu SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32 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 $5,313. Our instant quote calculator confirms the installed price for your home from your address.

What room size does the Fujitsu SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32 suit?

It is rated for rooms up to 100 m², making it a strong fit for large open-plan areas. 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 SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32?

The indoor unit runs at 36 – 46 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 SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32 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 room reaches temperature, 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 SET-AUTH45KRTA-3PH-T5 12.5kW Inverter Cassette Split Systems 3 Phase | R32 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.
