Calling Sarah
CoolAir Heating & Air
One request hands the AI voice its brain, its ears and its script.
Then the phone rings. He speaks first.
SarahUh, yeah, I’ve got a minute. What’s this about?
BrianMm, gotcha. Quick one: when your guys are up on a roof in July, how many calls slip through?
script · “Let them talk — ask, don't pitch”
SarahHonestly? A lot. Summer’s crazy.
BrianYeah… that’s rough. We built a voice agent that picks up every call, books the job.
script · “Don't quote price or explain features. That's for the specialist call.”
SarahWe tried an answering service. Didn’t love it.
BrianTotally fair. That’s exactly what the specialist walks you through, fifteen minutes.
script · “Objections = curiosity. Acknowledge. Reframe. Redirect to booking.”
BrianI got Thursday afternoon or Friday morning. What’s better?
script · “Never ask IF. Ask WHEN.”
SarahThursday afternoon. Two o’clock?
BrianDone. I’ll shoot you a calendar invite right now. Appreciate you, Sarah.
script · “Confirm day + time”
Every line he says follows a rule in his script.
He never asks if. He asks when.
