Points to plan for in Hayes
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.
Filters
Filter grades should match the original design or current guidance for the building.
Access and parking
Town-centre jobs in Hayes 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.
