What to think about in Harpenden
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Access and parking
Town-centre jobs in Harpenden 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.
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.
