The old desk is a voicemail box. The caller hangs up, and the insulation crew finishes before anyone knows the house misses 3 ACH50. Nobody wrote down the volume, the target ACH50, and which house.
Daisy keeps that on the note and reads it back. The Blower CFM shows CFM50 the target implies from those counts. The company that calls back starts from the note, not from "what were you calling about."
ACH50 is a measured blower number. Square footage alone does not prove the house hits the target.
A local tester sets the fan and writes the number. Daisy does not seal the house. The difference is the note, not a louder greeting. Lite is $99 per month, 1 seat.
