Residential

Ductwork in apartments and houses are typically of a smaller dimension and accumulated dust therefore has a larger restriction of the airflow. Reports are showing that it actually can make your electricity cost for the fan rise with up to 5% per year.

Apartments are according to the EN 15780:2011 standard classified as “Medium” with a recommendation to inspect the ductwork every 48 months and that the acceptable level for cleanliness is 3,0 gram of dust per square meter in the supply ductwork.
All dust and debris will be collected in transportable filters and disposed of according to local requirements.
