Local points to consider
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Leased premises
If your Limavady 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.
