Fujitsu Air Conditioning Systems – Powered by ACL London

At ACL London we specialise in delivering the most reliable, efficient and innovative climate‑control solutions for homes, offices and commercial spaces across the capital. Our partnership with Fujitsu – a global leader in HVAC technology – enables us to offer a complete portfolio of air‑conditioning systems that combine cutting‑edge inverter technology, quiet operation and industry‑leading energy performance. Whether you are upgrading a historic townhouse in Kensington, fitting a modern office block in Canary Wharf, or designing a boutique hotel in Shoreditch, Fujitsu’s diverse range of models provides the perfect fit for every application.

Why Choose Fujitsu?

1. Inverter‑Driven Efficiency
Fujitsu’s proprietary inverter compressors continuously adjust motor speed to match the exact cooling or heating load. This results in up to 40 % lower electricity consumption compared with conventional fixed‑speed units, helping you meet the UK’s tightening carbon‑reduction targets while keeping utility bills under control.

2. Whisper‑Quiet Operation
The brand’s advanced acoustic engineering delivers sound levels as low as 19 dB(A) for indoor units – quieter than a soft whisper. For residential installations this means an undisturbed night’s sleep; for offices and cafés it translates into a pleasant, distraction‑free environment.

3. Seamless Smart Integration
All Fujitsu indoor units are compatible with the latest smart‑home ecosystems. Through the Fujitsu General Wi‑Fi controller, users can adjust temperature, fan speed and mode from a smartphone, tablet or voice‑assistant (Amazon Alexa, Google Assistant). The system also supports scheduled operation, geofencing and energy‑usage analytics – tools that modern building managers demand.

4. Robust, Long‑Life Design
Built to European standards, Fujitsu systems feature corrosion‑resistant coil finishes, self‑cleaning filters and highly durable compressors. The company backs its products with up to a 5‑year warranty on compressors and a 10‑year warranty on heat exchangers, giving clients confidence in long‑term performance.

The Fujitsu Model Line‑Up Available Through ACL London

1. Split‑System Air Conditioners – Ideal for Residential & Small‑Scale Commercial

• Fujitsu ASU Series – Compact wall‑mounted units ranging from 2 kW to 9 kW cooling capacity. Perfect for single rooms, apartments and boutique retail spaces.
• Fujitsu Airstage™ 5 – An evolution of the classic split system, offering higher SEER (Seasonal Energy Efficiency Ratio) values, enhanced dehumidification, and a sleek, low‑profile indoor cassette.

2. Multi‑Split Systems – Flexible Zoning for Larger Homes and Offices

• Fujitsu Airstage™ 9 – Supports up to 8 indoor units (wall‑mounted, ceiling cassette, or ducted) from a single outdoor condensing unit. Ideal for open‑plan offices, loft conversions, and multi‑room dwellings where individual temperature control is essential.

3. Ducted (Central) Systems – Whole‑Building Comfort

• Fujitsu Airstage™ 10 – A fully concealed, low‑profile ducted solution delivering up to 16 kW of cooling/heating capacity. The system integrates with a single, high‑efficiency indoor air handler, providing uniform temperature distribution throughout the property.
• Fujitsu Airstage™ 11 – Designed for larger commercial premises, this high‑capacity ducted solution can be paired with multiple indoor air handlers for simultaneous zone control across multiple floors.

4. Commercial & Industrial Solutions

• Fujitsu Water‑Cooled Chillers – Energy‑efficient water‑cooled units for large‑scale HVAC plants, data centres, and industrial facilities.
• Fujitsu VRF (Variable Refrigerant Flow) Systems – Advanced multi‑zone technology that delivers simultaneous heating and cooling to separate zones from a single outdoor unit. The VRF platform is perfect for mixed‑use developments, hotels and office towers where space is premium and energy performance is critical.

Key Features Across All Fujitsu Models

Choosing the Right Fujitsu System for Your Project

1. Assess the Load Requirements – Our accredited engineers use the latest BTU‑calculation software to determine the precise cooling and heating load of each space, ensuring the selected unit is neither undersized nor oversized.
2. Define Zoning Needs – For properties with diverse usage patterns (e.g., a restaurant with a kitchen, dining area, and private rooms), a multi‑split or VRF system offers independent zone control, delivering comfort where it matters most.
3. Consider Installation Constraints – In listed buildings or heritage sites, the discreet indoor units of the Airstage™ series or concealed ducted solutions can be installed with minimal visual impact.
4. Budget & ROI – While upfront costs vary by model, the energy savings delivered by Fujitsu’s inverter technology typically result in payback periods of 3‑5 years for residential installations and even faster returns for high‑usage commercial sites.

Frequently Asked Questions

Q: Can Fujitsu air conditioners heat as well as cool?
A: Yes. All Fujitsu split, multi‑split and ducted units feature reverse‑cycle heat pump technology, delivering efficient heating down to –15 °C (5 °F).

Q: How quiet are the outdoor units?
A: Outdoor condensing units operate at a sound level of 48 dB(A) to 55 dB(A) depending on capacity – comparable to a normal conversation.

Q: Are Fujitsu systems compatible with existing building management systems (BMS)?
A: The majority of Fujitsu commercial models support BACnet, Modbus and LonWorks protocols, allowing seamless integration with most BMS platforms.

Q: What maintenance is required?
A: Routine checks (quarterly for commercial sites, bi‑annual for residential) include filter cleaning, coil inspection and refrigerant pressure verification. ACL London’s maintenance contracts cover all tasks and provide documentation for compliance audits.
