How it works in Lisburn
Survey
We size the unit to the room and agree indoor and outdoor positions and the pipe route. For sites in Lisburn we confirm access and parking beforehand.
Mount the units
Indoor unit on a mounting plate, outdoor unit on brackets or a frame with anti-vibration mounts.
Pipe and wire
Pipework, interconnecting cable and condensate are run and made off neatly.
Test and commission
Pressure test, evacuation, any extra refrigerant charge, then commissioning and handover.
Points to plan for in Lisburn
Outdoor unit position
Outdoor units need air flow and access, and should be away from neighbours' windows to keep noise down.
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.
One outdoor unit, many rooms
Multi-splits save wall space but share a single compressor. For server rooms or critical spaces we recommend dedicated systems.
Leased premises
If your Lisburn 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.
Typical premises in Lisburn
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
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).
