Commercial ventilation brings outdoor air into a building and removes stale air, using fans and ductwork to supply and extract air at the rates needed for the number of people and the activity.

Before you book in Dunbartonshire
Noise
Fans and grilles are selected and attenuated to keep noise down.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
Premises we work in around Dunbartonshire
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.

Compliance in Scotland: refrigerant work falls under GB F-gas rules, and systems with an effective output of 12 kW or more need a periodic energy inspection (often called TM44).
