Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Leased premises
If your Keynsham 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.
Noise
Fans and grilles are selected and attenuated to keep noise down.
Access and parking
Town-centre jobs in Keynsham 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.
