Fans and grilles are selected and attenuated to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Darton are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
