How a job in Belfast works
Survey
We measure the space, check the ceiling void, wall construction, glazing and occupancy, and agree where indoor and outdoor units can go.
Design and quote
You get a written specification with unit sizes, positions, pipe routes and a fixed price — plus any planning, landlord or noise points to resolve first.
First fix
Pipework, cabling and condensate runs go in, usually above ceilings or in neat trunking, before the units are hung. In Belfast we agree timings around your opening hours.
Install and test
Indoor and outdoor units are fitted, the system is pressure tested with nitrogen, evacuated and charged with refrigerant.
Commission and hand over
We set up controls, check air flows and temperatures, show your team how to use it and hand over the F-gas and commissioning paperwork.
Local points to consider
Condensate
Every cooling unit produces water. We route it to a drain by gravity where possible and fit a quiet condensate pump where not.
Working hours
Most Belfast businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Planning and noise
Outdoor units on commercial buildings often need planning permission — particularly on a front elevation, in a conservation area or on a listed building — and councils may ask for a noise assessment.
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.
Premises we work in around Belfast
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
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.
