Drip trays and coils must be kept clean to avoid biological growth.
Access and parking
Town-centre jobs in Kent often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Conservation areas
Historic streets and listed buildings in and around Kent are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Typical premises in Kent
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
