Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
Filters
Filter grades should match the original design or current guidance for the building.
Working hours
Most Antrim businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
