What to think about in Castlereagh
Diversity
Not every room peaks at once; good design accounts for diversity so central plant is not oversized.
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.
Noise
Outdoor unit noise is designed in from the start, not fixed afterwards.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Who we work with in Castlereagh
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
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).
