Things to check in Caterham
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
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.
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
Conservation areas
Historic streets and listed buildings in and around Caterham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
