Common questions about the Fujitsu 5.2kW Multi Head Indoor Unit Only ASTH18KMTD

How much does the Fujitsu 5.2kW Multi Head Indoor Unit Only ASTH18KMTD 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 $531. Our instant quote calculator confirms the installed price for your home from your address.

What room size does the Fujitsu 5.2kW Multi Head Indoor Unit Only ASTH18KMTD suit?

It is rated for rooms up to 40 m², making it a strong fit for medium living 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 5.2kW Multi Head Indoor Unit Only ASTH18KMTD?

The indoor unit runs at 29 – 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 5.2kW Multi Head Indoor Unit Only ASTH18KMTD cost to run?

Assuming a typical Sydney tariff of 33–35c/kWh: at full output this unit draws roughly 1.4–1.5 kW of electrical input (typical efficiency for a modern inverter of this capacity), which works out to approximately 48 cents to 54 cents per hour. Real-world costs are usually lower once the room reaches temperature, because an inverter throttles right back. Your exact tariff, the model's rated input power, insulation, thermostat settings and system sizing all move the number.

What warranty does the Fujitsu 5.2kW Multi Head Indoor Unit Only ASTH18KMTD 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.
