Where needed, we quote for fan upgrades or replacement.
Local points to consider
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
Filters
Filter grades should match the original design or current guidance for the building.
Leased premises
If your Oxford premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Premises we work in around Oxford
- 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.
