Points to plan for in Hertford
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
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.
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
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.
