Things to check in County Antrim

Replacement logistics

Large AHU replacements need craneage, road closures and careful programming.

Leased premises

If your County Antrim 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.

Filters

Filter grades should match the original design or current guidance for the building.

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.

Typical premises in County Antrim

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).
