in denmark we must build good houses så it is importennt that the heat cant com out of the hause so we test it whit af blower door

Seems all that is being explained when the blower/fan is in operation is the details of how things are measured.
Simply put, your front door is blocked off and a powerful fan is placed at the bottom. When the fan is in operation, it simulates 20 mile an hour wind hitting the house. This will allow all windows, doors and other surfaces to be tested for proper seal. Much easier than simply using your hand.

Sound quality is acceptable, at best. It is hard to understand what is going on and why the people on the screen are doing it.
The sound quality comes and goes as the equipment is run.
Very poor explanation of ACH. Explain why a certain number of air changes is good, but above 1 ACH costs extra to heat the home.
