What to think about in Barnet
Filters
Filters must be changed regularly to keep air flow and air quality up.
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.
Summer bypass
A bypass avoids warming incoming air in summer.
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.
