Before you book in London
Repeat failures
If a system has failed several times, we compare the cost of repair against 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.
Switch it off
If water is coming through a ceiling or the unit is tripping, switch it off at the isolator until it is checked.
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.
Who we work with in London
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
- Schools and education: classroom cooling, ventilation and IT room cooling, installed in the holidays.
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).
