Before you book in Belfast
Grease
Units near kitchens need cleaning more often, and sometimes relocating.
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.
Frequency
Most units need a deep clean every one to two years; kitchens and salons more often.
Conservation areas
Historic streets and listed buildings in and around Belfast are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.

In Northern Ireland, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under EU F-gas rules that apply in Northern Ireland, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
