What to think about in Northolt
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.
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Conservation areas
Historic streets and listed buildings in and around Northolt are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
