Merry Christmas first of all
Now my question:
When changing the external filters of our central ventilation system with heat recovery for the first time, I unfortunately had to find that the intake and exhaust openings are swapped, i.e. it is diligently filtering the exhaust air and the supply air enters the system unfiltered. Can I demand a cleaning of the system from the contractor in addition to the defect rectification (he will only replace the "end pieces")? (The system has currently been running for 6 months and in the meantime the street was also worked on, so there must have been a lot of dust in the air)
