From enquiry to handover in Surrey
Assess
We work out how many people use each space and the fresh-air rate needed.
Design
Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls. We keep work areas in Surrey screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
Before you book in Surrey
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
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.
Who we work with in Surrey
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
