Fan upgrades and better controls can cut energy use significantly on older units.
Access and parking
Town-centre jobs in Dover 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.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Types of premises we cover in Dover
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
