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.

The steps for a project in Merseyside
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 Merseyside screened and tidy at the end of each day.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Heat recovery
Bringing in cold air in winter costs energy. Heat recovery units reclaim much of it.
Conservation areas
Historic streets and listed buildings in and around Merseyside are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Types of premises we cover in Merseyside
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
