How a job in Castlereagh works
Survey the floor
We look at the ceiling void, the grid layout, window orientation, occupancy and where the outdoor plant can go.
Zone the space
Open-plan, meeting rooms, reception and IT rooms are treated as separate zones with their own controls.
Coordinate the ceiling
Unit positions are set against the lighting and grid layout so cassettes and grilles sit neatly. In Castlereagh we agree timings around your opening hours.
Install around the business
Work is phased by area or done out of hours so staff can keep working.
Commission and train
Controls are set with sensible limits and scheduling, and we show your facilities lead how to manage them.
Before you book in Castlereagh
Fresh air
Air conditioning recirculates air; it does not provide fresh air on its own. Many offices need ventilation alongside it to meet the Building Regulations.
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.
Out-of-hours use
If staff work late or weekends, zoning lets you run only the areas in use.
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.
Who we work with in Castlereagh
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
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.
