Drip trays and coils must be kept clean to avoid biological growth.
Working hours
Most Derby businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Filters
Filter grades should match the original design or current guidance for the building.
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.
