Hi! My name is Joshua Lindsey with CFM Building Science Solutions. On behalf of Expert Village,
we are going to do a duct test in this house. We've got a 196 as our fan pressure. The duct
loss was 83.
What I mean by 83 is this house is 1789 square feet in this house. We want to be less than
6 percent of that square footage, so 1789 times .06, pretty easy. My loss in this house
needs to be a 107. We were at 83 so in other words this house is down about 4 percent of
duct loss. That is great! Older homes they've got a lot of duct loss and they are going
to up like about 20 percent of your square footage. That is not good.
