The steps for a project in Crawley
Assess
We work out how many people use each space and the fresh-air rate needed.

Fan, duct and grille sizes are designed for air flow, noise and energy use.
Install
Ductwork and fans are installed and connected to controls. In Crawley we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Points to plan for in Crawley
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Building Regulations
New or altered ventilation in England must meet Approved Document F. We design to it and hand over the commissioning records.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Premises we work in around Crawley
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- 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).
