What to think about in Southampton
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
Access and parking
Town-centre jobs in Southampton 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.
Filters
Filter grades should match the original design or current guidance for the building.
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.
Who we work with in Southampton
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
