How to do a Blower Test

Video Transcript

"Hi! I'm Joshua Lindsey with CFM Building Science Solution. On behalf of Expert Village, we are going to be doing a blower door test on this home. So now it is asking me what ring, what flow ring I want to go with. On the fan here, this is ring A, B and C. Quite normally it is going to be B that we are going to take off. We are going to leave ring A on there. If it was a really big house, we would be going with ring A and as we move into a smaller house, we would be installing back on ring B. Obviously ring C just blocks the whole thing. So ring C is what we use when we want to close the whole thing off. So on here we are just going to pick ring A and go ahead and proceed with the test. And the fan takes off and the computer program is running the fan up. If you notice back on the computer program, it is getting a little bit loud in here but back here on the computer program, we are looking at fan pressure right here. It is a 161 and it is taking those samples again."
