How a job in Cardiff works
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. In Cardiff we agree timings around your opening hours.
Balance
Air flows are measured and balanced to the design.
Local points to consider
Noise
Fans and grilles are selected and attenuated to keep noise down.
Leased premises
If your Cardiff 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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Conservation areas
Historic streets and listed buildings in and around Cardiff are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Cardiff
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- 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.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
In Wales, 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.
