Belfast and surrounding areas
Belfast is one of the main commercial centres in County Antrim, with city-centre offices, retail streets, hospitality venues and business parks on its edges.
We work across Belfast's postcode districts, including BT1, BT2, BT3, BT4, BT5 and BT6. We also work in nearby Castlereagh, Newtownabbey and Lisburn. In Belfast, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
What the job covers
- Survey of void depth and duct routes

How it works in Belfast
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 Belfast 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
Return air
Every ducted unit needs a return air path; we design it rather than rely on gaps under doors.
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.
Noise
Duct sizes and grille velocities are chosen to keep noise down in quiet rooms.
Access and parking
Town-centre jobs in Belfast 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.

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.
