Local points to consider
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
Conservation areas
Historic streets and listed buildings in and around Morden are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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.
