The Fujitsu Comfort 9.5kW reverse cycle split system is the highest-output wall-mounted unit in the Comfort range, designed for very large open-plan spaces, combined multi-zone living areas, or commercial-adjacent applications where ducted systems are not practical.
Final sizing should be confirmed through an on-site assessment, as insulation, ceiling height, glazing, sun exposure and room layout can all affect the right unit choice.
Overview of Fujitsu Comfort 9.5kW Reverse Cycle Split System
▾The ASTH34KNTA pairs with the AOTH34KNTA outdoor unit and delivers 9.5kW of rated cooling and 10.3kW of rated heating. At this capacity, it is typically the appropriate choice for very large open-plan areas — extended living-dining-kitchen combinations in larger homes, high-ceiling spaces, or rooms with significant heat loads from unshaded glazing. The all-DC inverter compressor operates across a rated range of 2.9 to 11.2kW cooling, providing substantial headroom on the hottest days.
The indoor and outdoor units share the same physical shell dimensions as the ASTH30KNTA — 1150mm wide indoor unit and 940mm wide outdoor unit — but the outdoor unit is taller (998mm vs 788mm) and significantly heavier at 62kg. The refrigerant charge increases to 2,300g of R32. Maximum pipe run is 30m. Pipe connections are 9.52mm liquid and 15.88mm gas.
The outdoor unit weight and height mean that structural support must be confirmed before installation. A purpose-engineered wall bracket or reinforced concrete slab is required. The outdoor unit should be positioned to allow adequate airflow clearance given its increased height. Operating range extends to -15 degrees Celsius in heating mode.
– 9.5kW cooling and 10.3kW heating — top of the Comfort wall-mounted range
– All-DC inverter with wide operating range (2.9–11.2kW cooling)
– Outdoor unit 998mm tall and 62kg — structural support confirmation required
– R32 refrigerant (2,300g charge)
– 30m maximum pipe length
– Super Quiet Mode at 34 dB(A) cooling / 33 dB(A) heating
Is the Fujitsu Comfort 9.5kW Reverse Cycle Split System right for your home?
▾– Very large open-plan living, dining, and kitchen areas above 60 m2
– High-ceiling or poorly-insulated large spaces where a smaller unit is insufficient
– Large home offices, showrooms, or workshop spaces where wall-mounted units are preferred
– Applications where the 30KNTA has been assessed as undersized

Energy Efficiency & Performance
▾The ASTH34KNTA achieves an EER of 3.49 for cooling and a COP of 3.39 for heating. The EER is comparable to the 30KNTA (3.41), maintaining reasonable efficiency at top-of-range capacity. The COP of 3.39 is the lowest in the Comfort range lineup, reflecting the efficiency trade-off at maximum output levels. Despite this, 3.39 still represents a significant advantage over direct electric heating, delivering 10.3kW of heat per 3.04kW of electrical input at rated conditions.
Under the ZERL system the unit holds 3.5 cooling stars in the average zone (4 hot, 4 cold) and 2.5 heating stars in the average zone. Cold-zone heating drops to 1.5 stars — the lowest heating rating in the range for the cold zone, which is relevant for Hunter Valley properties that experience more sustained winter cold. The wide inverter range helps maintain stable output during temperature fluctuations, though the unit’s heating efficiency at very low outdoor temperatures is more limited than the smaller models.

Frequently Asked Questions
▾How large a space can the ASTH34KNTA handle?
At 9.5kW cooling it is designed for very large open-plan areas, typically 65 m2 and above, depending on insulation, ceiling height, and aspect. Your installer will assess the specific space before specifying.
Is this unit appropriate for a residential home?
Yes, where the space genuinely requires it. It is most commonly used in larger open-plan homes or homes with high heat loads. Your installer should confirm that a smaller unit cannot adequately cover the space -- oversizing has both cost and efficiency implications.
What support does the outdoor unit need?
The AOTH34KNTA weighs 62kg and stands 998mm tall. It requires a purpose-rated wall bracket or reinforced concrete slab. This must be confirmed and prepared before installation day.
What is the outdoor noise level?
Outdoor sound pressure is 58 dB(A) cooling and 59 dB(A) heating -- the highest in the Comfort range. Placement relative to neighbouring properties and outdoor living areas should be considered at quoting stage.
What warranty applies?
5-year full parts and labour warranty on all Fujitsu General domestic systems.
Can it replace an older large-capacity ducted or split system?
Possibly, depending on what it is replacing. For ducted systems, this is a different delivery method and will not replicate multi-zone distribution. For a like-for-like large split system replacement, your installer will confirm pipe compatibility and structural requirements.
