Never miss another no-heat or no-cool call again.
Every missed call becomes someone else's new customer. Dial 72 answers 24/7, books the job on the spot, and wins you the after-hours emergencies other shops sleep through.
Example: a live call from Sarah Johnson comes in reporting no heat, with the indoor temperature at 58 degrees. Dial 72 captures her phone number and address, identifies the furnace as the system, and books an appointment for later that day.

THE PROBLEM
HVAC emergencies don't wait.
When a call goes unanswered, the caller dials the next shop on Google. Dial 72 makes sure you're the one who answers.

It's 95° outside.
They need cooling now.
When it's this hot, customers call multiple companies. The first one to answer gets the job.

It's 20° outside.
They need heat now.
When it's this cold, customers call multiple companies. The first one to answer gets the job.
Dial 72 makes sure the next number is still yours.

FROM HVAC PEOPLE, TO HVAC PEOPLE

What do missed calls cost you?
Slide to how many after-hours or overflow calls you miss in a busy week. The estimate uses the same averages cited above: $180 for a routine call, $900 or more for a true emergency, with roughly one call in five being an emergency.
An estimate, not a promise. Every shop's mix is different.
Formula: weekly misses x 4.3 weeks x blended $324 average (80% routine at $180, 20% emergency at $900).

Questions owners actually ask.
Does she sound robotic?
No. Natural voice, contractions, real pacing. Most callers never notice, and if someone asks, she's honest about being the AI assistant.
Can callers reach a human?
Instant transfer to you or your on-call tech, with the full call context passed along so nobody repeats themselves.
Do I keep my number?
Yes. Simple call forwarding. Keep your number and your current phone system.
What happens after hours?
That's the whole point. She never sleeps. Nights, weekends, holidays, all answered the same way.
Is there a contract?
No. Month-to-month, cancel anytime.
Can she tell a real emergency from an impatient customer?
Yes. She triages by your rules: no-heat/no-cool in extreme weather, vulnerable people, or medical equipment escalate to your on-call tech; everything else books a slot.
