Things to check in Lerwick
Space
Units need space in the ceiling void or a plant area with access for filter changes.
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.
Summer bypass
A bypass avoids warming incoming air in summer.
Leased premises
If your Lerwick premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
