Things to check in Cardiff
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Access and parking
Town-centre jobs in Cardiff 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.
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
Conservation areas
Historic streets and listed buildings in and around Cardiff are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Who we work with in Cardiff
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
