From HVAC people,
to HVAC people.
Dial 72 wasn't built in a software office. It was built by people who've worked in and run HVAC shops, for the calls they used to miss.
Why "Dial 72"
72°F is the setpoint. The number every thermostat argument lands on, the temperature this whole trade exists to deliver.
Every service call is the same story: a house drifted away from 72 and someone grabbed a phone.
"Dial" points both ways: the thermostat dial and the phone call. Dial 72 is who answers.
Our Story
Nobody had to explain this trade to us.
The team behind Dial 72 includes people who've worked in and run HVAC shops. That's where Bella's rules come from: triage the emergency, flag the replacement lead, and never quote a price over the phone. It's how a good shop already runs.
Built for one trade, not fifty
Bella isn't a generic phone bot with an HVAC label slapped on. She knows a heat pump from a furnace, a no-cool emergency from a filter change, and she asks the questions you'd ask (system type, brand, symptoms, address, callback number) so the job shows up pre-qualified.
She backs up your techs, she doesn’t replace them
Bella answers the phone and books the work. She never diagnoses over the phone and never guesses a price. That's your tech's job, in person. She just makes sure the call gets answered and the job gets on the calendar.
Honest by design
If a caller asks whether they're talking to a person, she tells them she's the AI assistant. No pretending, no scripts, no phone-tree maze. Most callers never ask, but the ones who do get a straight answer.
A missed call is the most expensive habit in the trade
62% of HVAC calls come after hours. 85% of people who can't reach you never call back. They dial the next shop on Google. Bella exists to close that gap: every call answered in under a second, day or night, without overtime or a new hire.
