Before you book in Derry
Smells
Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.
Conservation areas
Historic streets and listed buildings in and around Derry 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.
Downtime
Each unit is out of action for about an hour while it is cleaned.
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.
Typical premises in Derry

Two rules matter for most businesses in Northern Ireland: EU F-gas rules that apply in Northern Ireland (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
