Points to plan for in Chelmsford
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Premises we work in around Chelmsford
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
