How it works in Castlereagh
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. In Castlereagh we agree timings around your opening hours.
Balance and commission
Air flows are measured and balanced, then the system is commissioned.
Local points to consider
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Leased premises
If your Castlereagh 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.
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.
Access and parking
Town-centre jobs in Castlereagh often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Types of premises we cover in Castlereagh
- 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.

Compliance in Northern Ireland: refrigerant work falls under EU F-gas rules that apply in Northern Ireland, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
