Daisy is taking a blower door testing call. The first useful line is the volume, the target ACH50, and which house. Without that, the callback is a second interrogation and the customer has already called someone else.
ACH50 is a measured blower number. Square footage alone does not prove the house hits the target.
The blower cfm turns the counts into CFM50 the target implies. That figure is a planning total for the company that claims the job. It is not a permit, a lab result, or a price.
A local tester sets the fan and writes the number. Daisy does not seal the house. Lite is $99 per month, 1 seat, on the company's own phones. Daisy repeats the note and the address, then the local company calls back.
