What to think about in Isleworth
Space
Units need space in the ceiling void or a plant area with access for filter changes.
Conservation areas
Historic streets and listed buildings in and around Isleworth are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Filters
Filters must be changed regularly to keep air flow and air quality up.
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 Isleworth
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.

- Gyms and leisure: high-capacity cooling and fresh air for gym floors, studios and changing rooms.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
