From enquiry to handover in Castlereagh

  1. Survey and loads

    We calculate loads zone by zone and check roof or plant space, risers and ceiling voids. For sites in Castlereagh we confirm access and parking beforehand.

  2. System design

    Outdoor units, indoor units, branch boxes and pipe sizes are designed together, including the refrigerant charge and any leak detection.

  3. Phased first fix

    Pipework and controls cabling go in floor by floor, often out of hours in occupied buildings.

  4. Pressure test and charge

    The network is pressure tested, evacuated and charged with the calculated refrigerant quantity.

  5. Commissioning

    Each indoor unit is commissioned and the controls set up, with as-fitted drawings and F-gas records handed over.

Before you book in Castlereagh

Leak checks

Larger VRF systems usually exceed 5 tonnes CO2 equivalent, so they need at least annual F-gas leak checks — more often at 50 tonnes and above.

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.

Refrigerant in occupied rooms

Because one network carries a large refrigerant charge, small rooms on the system are checked against the safety limits in BS EN 378 and may need leak detection.

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.

Who we work with in Castlereagh

  • Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.

In Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
