Historic streets and listed buildings in and around Sunbury-on-Thames are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.

R22

Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.

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.

Typical premises in Sunbury-on-Thames

  • Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
  • Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
  • Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
  • 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.
