Before you book in Durham
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
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.
Filters
Filter grades should match the original design or current guidance for the building.
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.
