Things to check in Blackheath
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.
Filters
Filters must be changed regularly to keep air flow and air quality up.
Leased premises
If your Blackheath 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.
