ᐅ How can you tell when the mechanical ventilation system is working properly?

Hello,

sorry if this is a silly question, but how can I tell if the mechanical ventilation with heat recovery is working properly? We just turned on the system after finishing the interior, about 6 weeks after moving into the house. According to the recommendation, we should only switch it on once most of the dust has settled.

Now I don’t hear anything from the system (except in the utility room when I’m standing right next to it). How can I be sure it’s working correctly? At the fresh air outlets, I only feel a very slight breeze.

Is this normal? ops:

Thanks,
Julia
