What to think about in Northampton
Replacement logistics
Large AHU replacements need craneage, road closures and careful programming.
Access and parking
Town-centre jobs in Northampton 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.
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.
Who we work with in Northampton
- 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).
