Cassette Type Air Conditioning
The Smart, Discreet Solution for Modern Spaces
Your specialist for high‑performance ceiling‑mounted cooling and heating – ACL London
Why Choose a Cassette‑Type Air Conditioner?
When a project demands powerful climate control without sacrificing interior design, a cassette‑type air conditioner is the answer. Mounted centrally in the ceiling, the unit delivers 360° airflow, ensuring uniform temperature distribution across the room while staying virtually invisible to occupants. The result is a clean, uncluttered ceiling line, lower noise levels, and an aesthetic that blends seamlessly with any commercial, office, or hospitality environment.
Key advantages
- Even, rapid air distribution – Four directional louvers create a balanced airflow that eliminates hot or cold spots.
- Space‑saving design – No wall or floor intrusion; the cassette sits flush with the ceiling grid.
- Quiet operation – The compressor and fan are housed in a sound‑insulated cabinet, typically producing less than 45 dB(A) in the occupied zone.
- Flexible installation – Suitable for suspended ceilings, raised floors, or plenum spaces, making it ideal for retrofit and new‑build projects alike.
- Energy efficiency – Modern units meet or exceed EU Energy‑Label A++ standards, delivering lower operating costs and reduced carbon footprint.

Applications Where Cassette AC Shines
| Sector | Why a Cassette Works |
|---|---|
| Office Buildings | Uniform cooling across open‑plan floors, low ceiling height, and silent operation for concentration. |
| Retail & Showrooms | Discreet units preserve visual merchandising; 360° airflow keeps products at optimal temperature. |
| Hotels & Hospitality | Guest rooms and public areas benefit from hidden units that maintain luxury aesthetics. |
| Healthcare Facilities | Precise temperature control and integrated filtration support infection control standards. |
| Education & Training Centres | Even climate reduces drafts on students; low noise supports learning environments. |
| Restaurants & Cafés | Ceiling placement frees wall space for décor and signage while providing consistent comfort for patrons. |

How ACL London Guarantees a Seamless Experience
- Consultation & Load Calculation
Our certified engineers perform on‑site assessments using the latest heat‑load software. We factor in occupancy, equipment heat, solar gain, and building orientation to size the cassette precisely—no over‑ or under‑sizing. - Custom Design & BIM Integration
Working with architects and interior designers, we embed the cassette model directly into your Building Information Model (BIM), ensuring clash‑free coordination and accurate material take‑offs. - Professional Installation
All our technicians are accredited under the UK Refrigeration and Air Conditioning Engineers (UKRACE) scheme. We follow strict safety protocols, secure proper duct sealing, and perform post‑installation testing to certify performance. - Commissioning & Handover
After fitting, we fine‑tune control parameters, verify airflow balance, and provide a comprehensive operation manual. Clients receive a digital asset register for warranty tracking and service scheduling. - Ongoing Maintenance & Support
ACL London offers tiered service contracts, from annual preventive maintenance to 24/7 emergency response. Our parts inventory includes all major OEM components, guaranteeing rapid turnaround and minimal downtime.
Energy Efficiency & Sustainability
The UK’s commitment to net‑zero by 2050 drives demand for greener HVAC solutions. Cassette‑type units excel in this arena:
- Inverter‑Driven Compressors – Variable speed operation matches real‑time cooling load, reducing electricity consumption by up to 30 % compared with traditional fixed‑speed systems.
- Smart Sensors & AI Controls – Integrated temperature, humidity, and occupancy sensors adapt performance on the fly, preventing wasteful over‑cooling.
- Eco‑Friendly Refrigerants – Most of our stocked models use R‑32 or R‑410A, which have lower Global Warming Potential (GWP) than older R‑22 systems.
- Heat Recovery Options – Certain models (e.g., Mitsubishi Electric’s City Multi) can capture waste heat for water heating or space heating, delivering a truly dual‑purpose solution.
In addition to lower utility bills, many of our cassette units qualify for Enhanced Capital Allowance (ECA) schemes and Reduced VAT on energy‑efficient equipment, delivering further financial incentives for forward‑thinking businesses.
Frequently Asked Questions
Q: How high should the ceiling be for a cassette installation?
A: Most cassette units fit within a 150 mm to 200 mm cavity, making them compatible with standard suspended ceilings (typically 300 mm above the finished floor). For low‑height spaces, we can recommend slim‑line models that require only 120 mm of clearance.
Q: Can the cassette provide heating as well as cooling?
A: Yes. Many manufacturers (e.g., Daikin, Panasonic) offer reverse‑cycle cassette units that deliver up to 6 kW of heating capacity, perfect for year‑round comfort in temperate climates.
Q: What maintenance is required?
A: Routine tasks include filter cleaning/replacement, coil inspection, refrigerant pressure checks, and fan motor inspection. Our service contracts cover these activities at intervals recommended by the OEM (typically every 6–12 months).
Q: Are there any noise concerns for occupied spaces?
A: Modern cassette units are designed for low sound levels, typically below 45 dB(A) at the occupied zone. Acoustic insulation within the ceiling cavity further reduces perceived noise.
