Before you book in Letchworth Garden City
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Access and parking
Town-centre jobs in Letchworth Garden City often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
