The steps for a project in Derry
Survey and route
We check void depths and plan routes for supply and return ductwork.
Design the air side
Grille sizes and positions are chosen for even air flow and low noise.
Install unit and ducts
The unit is hung with access for servicing; ductwork and grilles are fitted. We keep work areas in Derry screened and tidy at the end of each day.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Points to plan for in Derry
Void depth
Low-profile ducted units can fit voids of around 250 mm, but ductwork adds depth. We measure the route as well as the unit position.
Leased premises
If your Derry 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.
Access
Filters and the unit need access for servicing — an access panel is non-negotiable.
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.
Typical premises in Derry
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
