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.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Types of premises we cover in Paisley
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
Compliance in Scotland: refrigerant work falls under GB F-gas rules, and systems with an effective output of 12 kW or more need a periodic energy inspection (often called TM44).
