Questions and answers

For homes, a common rule of thumb is to clean the ducts roughly every 5–10 years (depending on their condition), service a heat recovery unit once a year and replace the filters at least twice a year. Check your unit’s manual for exact intervals.

If you notice dust around the valves, weak extraction, damp or lingering odours, don’t wait. Commercial premises and spaces with heavier use usually need cleaning more often.

We cover furniture and floors and tidy up after ourselves when we’re done.

You usually don’t need the association’s permission to clean your own apartment’s valves, ducts and unit. The building’s shared shafts and roof fans are managed by the association, and their cleaning is agreed with it.
