What to think about in Didcot
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
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.
Typical premises in Didcot
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
