Local points to consider
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.
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
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.
Types of premises we cover in Trowbridge
- 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.
