Before you book in Belfast
Future use
Allow for growth in occupancy or IT load.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
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.
Types of premises we cover in Belfast
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
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).
