Points to plan for in London
Smells
Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.
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.
Downtime
Each unit is out of action for about an hour while it is cleaned.
Access and parking
Town-centre jobs in London often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.

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.
